I reached out with photos of a window that needed repair, and Edgar took the time to review them and provide detailed feedback. He expertly identified issues with a temporary repair performed by a third party and clearly explained the best way forward. He also explained pricing and what sort of scope of work I would be looking at if I did elect full window replacements. Even though I ultimately didn't proceed with Crystal Exteriors' services (at their own recommendation), I truly appreciated the honesty, professionalism, and helpful advice. It's heartwarming to find a business that prioritizes doing what's right for the customer over making a sale. When it does come time to replace my windows, Crystal Exteriors will be my first choice. I strongly recommend this business for anyone seeking knowledgeable, trustworthy, and customer-focused service. read more

Jason and his team are amazing to work with. Prices are competitive, they are knowledgeable, responsive, and care about their customer's satisfaction. They replaced our roof five years ago and we had them back to replace our siding/gutters because we had such a positive experience. read more

We learned Crystal Exteriors from our neighbor who installed their window several years ago. We contacted Edgar in late May 2025 for initial assessment. Edgar went through brochures with professional knowledge and addressed all our questions. Within two days, Edgar provided the detail quote of the entire house window replacement. After further questions and answers, we signed the contract in late June. Before the ordering the materials, they made second visit to ensure validation of window size. In late July, Jamie and Ivan with three additional team members showed up to install all 27 windows. They also examined and assessed of the surrounding window frame's condition to determine if additional works required. The next day they performed perticulary details to wrap external window frame with aluminum protection. They examined and sealed all the inside and outside window frame, testing back and force to ensure window perform based on their professional standard and manufacturing requirements. They also educated us about feature of the windows and maintenance of cleaning. They provided warranty registration to us before they charged us final payment. Based on two days of installation and subsequent Q&A inquiry. We would strongly recommend Crystal Exteriors for their quality service, honest dialogue, professional installation, cleaning everything of leftover. Most importantly, Crystal Exteriors'' quoted price on my whole house window replacement project is in the medium-low cost based on our research. We are very satisfied for the works and very lucky to choose this company. We wish Crystal Exteriors best for their business success in the future. Mark Wu read more

Horrible customer experience with the quoting process with crystal exteriors. We reached out to them for a quote on a fairly simple job. Their quote was easily 6-7x what we received from all the other vendors. Very rude business wouldn't recommend doing business with them. read more

Crystal replaced my shutters and the trim around a patio door. The cost was very reasonable, the installation team was excellent, and the job was finished quickly. When the installation team discovered a minor problem installing the trim due to my house having an uneven supporting surface, they worked with me on-the-fly to develop a solution. And their attention to detail was impressive. Crystal rightfully earns all the 5 star reviews - they are highly recommended! read more

Crystal Exteriors team was fabulous from quote to delivery of gutter replacement for our whole house. We got a quick response to our online request for a quote and Edgar was at the house within a week and at a time that was mutually convenient to give us a quote. He was thorough in explaining the quote, including the "forks in the road" that might lead to a more expensive total cost. The pricing (including the possible expansion in scope & cost) was completely transparent. When it turned out that we had some rotten fascia and a flat roof that would need replacement, the team was diligent in sharing very clear photographs of the damage, as well as transparent that the flat roof repair we needed was not in their wheelhouse. They paused the work so that we could get the flat roof repaired and then resumed installation as soon as the other contractor had finished the work. I can't imagine a better experience. read more

We had 4 estimates. Crystal Exteriors was very competitive. Along with that, Jason explained without pressure the options. The estimate was the most detailed and easy to read. They arrived early on the appointed day and got right to work. The team worked well and are polite and hard working. The roof was finished on time. The cleanup is meticulous. I really feel as if I made the right choice. There is a level of trust hopefully I won't but, even if needed it, I feel they will stand by the work. The quality of the work and products used all contribute to the value for the cost was easily one of the best experiences I've had dealing with a company.I highly recommend. read more

Crystal Exteriors just completed a siding job for my house, a 1989 colonial construction originally with aluminum siding. The entire process was seamless and entirely pleasant and uneventful. Jason the co-owner was professional and informative and stay in contact throughout the job from proposal to completion. The crew was extraordinary and I was able to easily monitor the work and discuss minor issues as they arose and see every one resolved without delay. The price was entirely competitive, received some 4 bids for the job and accepted this bid based on my confidence in this company as well as the price. This turned out to be without doubt the BEST experience I have ever had with a contractor and at 73, i have dealt with plenty over the years. Highly recommend! read more

We recently had Crystal replace the roof on my daughter's house and the experience was top notch from start to finish. Mr. Jason Lim provided a detailed quote within a day. The price was easily the lowest of the 3 quotes we received. Crystal's quotes are the most detailed I have seen from any contractor with materials and labor listed in a line-by-line fashion that makes it very easy to understand what all the components of the job cost. Mr. Lim patiently answered all of our questions about the quote and explained the process and exactly what would happen on the day of installation. The roofing crew was very professional and respectful of our property. The lead foreman was easy to talk to and also answered any questions we had as the job progressed. They completed the whole job in one day and cleaned up so well that you coudn't tell they had ever been there. Kudos to Mr. Jason Lim and the entire Crystal Exteriors team. This was the 2nd time we used Crystal as they installed new siding and gutters on my daughter's house last year. Once again they were the lowest price and provided superior quality and value. From now on I won't waste my time getting multiple quotes for future exterior projects. Crystal Exteriors is the only contractor you need to call for any home exterior project. They are excellent! read more

Crystal Exteriors just replace our two sliding glass doors and we couldn't be happier. The service was excellent and very considerate, the new doors look great and work wonderfully, and the price was more than reasonable. Mr. Li is super considerate and respectful and we were happy with our experience from beginning to end, I would definitely hire this company again. read more

Replaced aluminum siding with vinyl siding. Great work. Started and finished on time, meeting our tight schedule. Everything was done perfect. Great workmanship. Very good price. Friendly staff. read more

I had my front door installed with a storm door as well. I love in a 1947 brick colonial and in its original form for the most part aside from the modern updates of wiring and all that jazz. I'd recently been gifted a new door by my Dad who sent the worst guy to come and install my door for me. He wasn't smart enough to know that the dimensions would not fit what I'd had. So after months of looking at a horribly placed front door, I was able to come on Yelp and find Crystal Exteriors. I ended up speaking with Mr. Li and he was so helpful and informative. He came to my home immediately and assessed my door. By the next day I had a fully written and professional estimate in my email per what we discussed and the kind of door that I wanted. I was so impressed. About a few weeks later the door was ordered and ready for install. Jamie and his crew have been doing this for 20 yrs I was told. They were so professional and knew exactly what to do. They were so clean and made sure to clean up any debris. I can't say enough great things about this experience as I cannot tel you how many crappy situations I've been in when it comes to hiring help regarding home improvements and repairs. I would definitely recommend them to anyone in need of new doors, windows or cosmetic updates to your home. The reviews helped me choose these guys and after my experience I see why. They know their work. They stick to what they're good at and I will be getting another door installed in my home by them next year. read more

Mr. Li is the man. I primarily stick to food reviews on yelp and honestly, when Mr. Li's guys started drilling and making god awful noises around 8am on a Saturday morning I wasn't happy. I was really quite livid. But at the end of the day we're super happy with the product (about 12 windows and a door). More importantly, I hope he doesn't mind me sharing this, but Mr. Li was grieving a loss in his family and still made sure the job was done. All during record breaking winds his team still showed up and did an awesome job. They sealed off our kitchen as they replaced the windows in a way I have never seen before. Like we could still do stuff in the kitchen as they worked while also minimizing the super cold temp. From the initial consultation to seeing how the guys worked during some pretty terrible weather conditions, we were impressed. Will definitely use again for other doors. So long as they start maybe a little bit later. read more

Crystal Exteriors replaced half our windows in 2006, and when we finally got around to doing the other half in 2020 we went right back to them! The pre-sale process is clear and straightforward, with no upselling or BS. The work they did in 2006 still looks great, and has remained entirely weatherproof. The recent work they did looks just as great, and the project manager was very attentive and professional in making sure we were satisfied. If we had any windows left to replace, we'd definitely use them again! And we recommend them strongly to others. read more

Very professional, easy to work with, very responsive to our questions and concerns from the beginning to the end of the process. Completed work replacing roof and multiple skylights in one day and completely cleaned the worksite after the job was finished. Highly recommended for any roofing work. read more

Crystal Exterior did an exceptional job on my home!The pricing was fair, honest, and comprehensively explained the justification for each aspect of the project. They were transparent about everything and finished on time. Plus, they were neat and cleaned up everything. Honesty and great customer service were key selling points, as I got quotes from other exterior companies in the area basically tried to rip me off. I highly recommend Crystal Exterior to anyone looking for high quality exterior work for a fair price! read more

We purchased a combination storm door and front door by Provia through Crystal Exteriors. We found Crystal through the recommendations in Washington Consumer Checkbook. We chose between Crystal and another excellent company who dealt with both Provia and another manufacturer. Edgar Li, the owner, was patient and thorough. He answered our many questions and worked with us on issues such as the alarm system sensor. The doors arrived exactly when he promised. The installation was easy, and the installers were professional and clean, everything went as smoothly as one could imagine. Edgar offered to return to install a mailbox and door stops that we purchased, which is really great service. Highest recommendation. read more

Great experience working with Edgar and his installation team. We originally had Edgar out a year prior to quote several new doors, but then we never followed up. Despite that, he was happy to come out again to measure a year later, then came by again to triple check before we signed a deal. He seems very knowledgeable about the product line and was always available to discuss questions, with absolutely zero sales pressure. The installers came on time, kept to themselves (this was during COVID 19), kept our house neat and tidy, and explained small issues that cropped up and how they were handling them. After install was complete they removed all debris and left out house looking cleaner than it was. Highly recommend these guys for new doors! read more

Crystal Exteriors is a company with the perfect balance of being cost effective while using top quality materials and having the skills for great installation. They are also professional, easy to work with, and honest. They did our roof, gutters, windows and door. Working with Crystal Exteriors has helped take some of the stress out of being a first time homeowner. We bought our first home this summer and ended up discovering that the previous homeowner took shortcuts wherever they possibly could, and they hired a terrible roofing contractor leaving us with a brand new roof full of leaks. We weren't going to make the same mistakes he did, we were going to do this right- so we did our research and met with several different roofing companies, local and big-name, before meeting Edgar and deciding to go with Crystal Exteriors. We chose them based on their reputation, knowledge, and professionalism as well as the extremely reasonable estimate provided and warranty on the work and materials. They did a total roof replacement, from the plywood on up. The job they did was meticulous, from the details like the flashing around the chimneys, to the cleanup of nails and debris at the end of the job. They completed the job in one day as promised, and David, the roofing supervisor with decades of experience, oversaw the job and met with me at the end of the day to make sure we were 100% happy. We were so impressed with them that we hired them to redo our gutters/downspouts, and again, the estimate was the most reasonable and the materials used and workmanship was top notch. We also hired them to replace our old basement door with a steel security door, and replace our old basement windows as well. Their prices were much lower than other companies that provide the same exact brand and items (ProVia Legacy door and ProVia Endure windows). The installers were professional and did an excellent job. I ended up recommending Crystal Exteriors to my mother and she got her gutters replaced by them. I found out later on that our realtor's other clients in the same neighborhood had their roof done by them as well and were recommending them. Edgar and David are honest, reliable, and take pride in their work. read more

I recently had my siding, roof and gutters replaced by Crystal Exteriors. All the work was performed professionally and on time. No evidence left behind {debris} after the work was completed. My thanks to Jason for a job well done. I would highly recommend Crystal Exteriors to all who are in need of their services. read more

We used Crystal Exteriors to replace an older wooden entry door in our home with a more up to date and higher quality fiberglass door as well as to replace locks on other existing doors in our home. We received a total of four quotes for this work, and Crystal Exteriors was very reasonably priced and we had a great comfort level with Edgar Li, who came to measure and discuss the project. I must say, having done a ton of work on our home and having used no less than 10 contractors in the last five years with some good and some bad, we were blown away by the professionalism, efficiency and quality of work by this company. If I need any of the other services they offer going forward I won't be wasting time getting quotes, Edgar will be my first and only call! I was truly incredibly impressed and very happy with our choice to use Edgar and Crystal Exteriors. read more

Crystal exteriors replaced our entire roof and gutter system. Competitively priced, very neat and professional. Couldn't have gone better.

Crystal Exteriors has done three projects with us, most recently replacement almost all of our windows. Prior to this project we replaced storm doors. They have been great to work with. Mr Li is a true professional, their communication is great, and the crew has been consistently courteous, skilled and efficient, and the work has been high quality. We have recommended Crystal Exteriors to a number of neighbors and look forward to our next project. read more

Professional, precise and polite. Our new door enhances our home and it was a completely painless experience. I highly recommend Crystal Exteriors. They left the area around the door looking spotless as well. I was impressed! read more

Edgar and his team replaced our front door and did an outstanding job. He was very patient throughout the sales process and provided many options to guide us. We love our new door! We chose the ProVia Signet series in a dark mahogany color with decorative side lights. The quality and styling are excellent. read more

Crystal Exteriors installed our new front and back doors this week. The process was SO easy; Jessica quickly emailed multiple quotes so I could compare features and finishes. Edgar came by to measure and talk through installation prior to making an order and even brought door finish samples for me to hold on to. They were very communicative throughout the whole process, including updates on production and shipping. Installation was quick and the installers were helpful in explaining the door features and functions before they left. I chose Crystal Exteriors because their prices could not be beat (when comparing the same exact products across 3-4 different installers), but I will keep coming back to them for our home exterior needs because of their friendly, professional, high-quality, and personalized service! read more

When we moved into our house two years ago we knew we would need a number of new windows and some doors. One window with no storm window was so bad that it had ice on it on the inside in winter. We had a few different companies provide an estimate. When Mr. Li arrived he was clearly a step above the others who came to look at the scope of work. We had initially planned to replace five old windows, three entry doors, and three awful storm doors. Mr. Li suggested that, given the location of the doors, we likely would not benefit from the storm doors and told us to consider just putting on new quality doors--which would also save us money. No other person doing an estimate suggested this. The storm doors served no purpose in our particular case so why spend the money. He also looked at the windows. He left us with books and color cards. Initially we were afraid that his preferred window makers would be too costly for us, but when the estimate came it was close to what other lower-quality windows would cost. He provided a complete recommendation and estimate within two days, including colors, types, and other options, and he encouraged us to do our homework on which windows and doors would be best for us before making a decision. It was nice that there was zero pressure. We replied with a few questions and add-ons, which he clarified quickly via email. We decided to go with the company and scheduled installation across two days. We thought that the estimate was so fair that we opted to have nine old wooden panel windows replaced (adding in the basement ones) instead of five, which he had already measured. The installers were on time and worked hard for two days (basement level to three stories up in the attic) in rough summer heat. We were especially happy that they removed the windows from the outside instead of carrying them through the house. This protected our wooden floors and kept the dust and debris to a minimum. They were a great team. We have a nearly 70 year old house so a few areas are uneven and tricky. We noticed that one window was a little crooked and after showing the team, it was fixed the next days. We are so impressed at the quality of installation. Every door and window opens correctly and are cleanly caulked. Two doors needed new interior trim and that was well done. The doors even have have caulking to match the color of the door on the exterior. Everything was hauled for disposal and packed when they were done. The doors have made a huge difference in our quality of life. (Our old doors had a bunch of separate keys for each one and were hard to open from the inside.) We have also noticed that the house cools better and we can now open our attic windows to release heat and get cross ventilation. We still have one front door that we did not replace. If we plan to change it we will definitely use Crystal Exteriors. Highly recommended. Trustworthy and professional. read more

We contracted with Crystal Exteriors for the replacement of our roof. Having completed other projects with them in the recent past, it was really a no-brainer to ask them to give us a recommendation. I called Jason to ask him to come by for an estimate, but a visit wasn't even necessary. We had an estimate that very same evening for a new roof with every possible material and contingency, and options ridge vents, pipe flashing, and chimney flashing, as well as additional costs for roofing plywood, if needed. We received an estimated installation window, even with the current shortage of construction materials. As it turned out, we later received a call from Jason to let us know that they could start a few days early. On the day for the installation, the crew showed up on time, with materials, and prepared to get started. Working expeditiously, they removed the old roof, install our new roof, cleaned up every nail and last piece of debris all in one day. We had the roof on this house replaced 25+ years ago. The previous roofer did a good job, but it took them 2 days to complete. Their invoicing, scheduling, and administrative back office all work in tandem to keep you informed and to set clear expectations on scope, materials, and costs. We had a great experience with Crystal Exteriors as our contractor for our new roof, and after having had such great experiences with this and previous projects, we've become customers for life. read more

Can't say enough good things about Crystal Exteriors. Great communication with Edgar, our new front door with sidelights is AMAZING, and Jamie and his team did a phenomenal job with installation. We couldn't be happier. read more

Start of project was delayed due to cold weather, but actual start to finish of work took 2 days. Looked very professional. Everything looks good, and no indication of any leaks. read more

Mr. Li was extremely helpful and accommodating in all of the prep leading up to the work. His team came out and did an outstanding install. It looks beautiful and operates smoothly. Jaime was very nice and the whole crew was very professional and took great lengths ensuring it was right and every detail was perfect. Have every intention of using again and highly recommend. Price was comparable with the bigger window and door companies so I preferred going small business and it was worth it. Thanks again to Mr. Li and his team read more

Had four mediocre builder quality sets of doors on our addition and one was even allowing water in from a poor threshold. Mr Li came out and gave a reasonable estimate on high quality ProVia doors and from the estimate to the installation did an amazing job. I cant recommend him highly enough - professional, great communication, and he takes so much pride in his work. Amazing customer service. read more

Mr. Li and his installation team did a top-notch window and door replacement for our 1937 home. We would not hesitate to select them for future work. read more

We had Crystal Exterior to do our siding and front door. We chose Crystal Exterior because Mr. Li was a true professional. He did not rush us into making a decision on the type of sidings we want nor the color. He actually left us the siding and shutter samples so we could take our time. We got another estimate from a different company, their price was comparable to Crystal Exterior but that other company wanted us to pick the color and type right away and didn't explain the process to us. Mr. Li's crew stayed on schedule and took their time with our siding; it came out better than what we expected. We love the outcome. We also asked Mr. Li to replace our front door. Again, he educated us on the door and left us with samples. The door came out great. We enjoyed the whole experience and would definitely recommend Crystal Exterior services. read more

A roof is a major investment in a home. It is the largest structure covering one's home. And it generally lasts between 15-20 years. If one does not choose the right company to do the roof, one will repent for years to come. After weeks of research I chose Crystal Exteriors. I am glad I did. The crew came yesterday and started the work of removing the shingles and putting on the new ones. They completed the job today. I watched them work and can tell you first hand that no other roofing company can do the kind of work they did. They removed the shingles and the black sheet under it and some places where the wood was bad they took that out and put new plywood. They replaced the skylight, too. Everything is BRAND NEW!! I could tell they were meticulous about doing the work. Even one of the owners, David, came 4 to 5 times to inspect the work. This company does not believe in doing mass production. They are a quality company with a very high quality crew that does high quality work. That is the bottom line. Everything is new on the roof. Even the flashing. Another roofing company that gave me an estimate said, they will change the flashing only if it needs to be changed! And I said, What? Can you repeat that? I did not give that other company a call. I chose Crystal Exteriors. So, anyone reading this review should not waste their time looking anywhere. I have the highest praise for this company and its qualified team. And if you want to know another thing, they are booked till December! That is how popular they are. They don't cut corners. They do not believe in second best. They do not say one thing and do another. They can be trusted to do a great great job. KUDOS to Edgar, David and their entire team of dedicated, caring professionals! read more

Edgar was great to deal with and the crew did a tremendous job. They were punctual, pleasant to deal with, and did great work. Thank you all for the A+ service, and we'll call next time we need a gutter, roofing, or siding job done! read more

Great job on new gutters, windows and a door! Workers were on time, courteous and professional. The owner was very professional and took time to explain processes involved Will hire them for similar work if ever needed. read more

I can't say enough good things about this company. Edgar Li the owner was professional, honest and extremely helpful in guiding us to pick the right door for our home. Everything went according to his explanations. The price was great with no hidden costs. They protected the area around where they worked so my dogs and I could go about our routines. Edgar worked easily and knowledgeably with the stone mason who put in the sill under the door and the stoop and sidewalk leading to the front door. Jamie, his installer has been with him for over 20 years and is also a real professional . Oh, by the way I am a perfectionist with NO complaints only smiles about our new door. I chose Crystal Exteriors because of the type of positive reviews in Yelp and Consumers Checkbook and everything went perfectly as the other reviews said. It was a great experience to meet and work with Edgar and his team. read more

Edgar came out to my home today. He was very thorough and took the time to go over the whole process. He made sure that I was in clear understanding of what needed to be done to the home. He even caught my previous contractors mistakes. I highly recommend him and his company to anyone wanting a professional job! read more
