In the Fall of 2020, my husband and I decided to remodel our run down 1978 home. We were spending more time at home due to Covid, and we were ready to finally make our home into a peaceful sanctuary for our family. After living here for almost 20 years, our "To Do" list had grown rather long. We needed windows, siding, bathrooms (no longer set in the 70's), and more room in our 1500 sq ft dwelling. We excitedly met with an architect to see how we could extend our house and add more windows and natural light in the process. We had the plans and were ready to start construction. Then, the general contractor we had chosen ghosted us. Knowing that this was going to be a big job that would require a very large chunk of change, we knew we needed to make an informed decision. We already had trust issues after having chosen a contractor recommended by a friend who flaked out on us. So, it's a big deal to make a decision about who is going to redo your home into a place that you will love and enjoy, stay on time, on budget and use our money wisely. This was our first major home project and we planned to meet with several contractors to find out how the process would work and how they could stay within our budget. We looked on Yelp first and searched for someone in our general location, (we love to support our local businesses). The first listing was Alter Construction. The reviews mentioned "responsive"," great communication'', "trustworthy'', "best materials", "great craftsmanship," all the things that you'd want in a general contractor. I checked out their website and really liked what I saw, so I filled out the form and got an immediate response to set up a phone call the next day. After speaking to Eli for the first time, I got a warm and friendly vibe. We set up a meeting at our home to discuss the project and when Eli and Cynthia came over we talked about what we wanted to accomplish and let them know that this remodel would totally change our quality of life going forward. They showed us some photos of their previous jobs and their qualifications were obvious, all of the projects were amazing. The happy client testimonials spoke to Eli and Cynthia's character and genuine desire to help us reach the quality of life we had longed for for many, many years. Needless to say, we never met with any other contractors, our minds were made up during that first meeting to work with Eli and Cynthia at Alter Construction. We went back and forth via email about what we needed and at our next meeting, we went over the scope of work, timeline, total cost of the project and the payment scheduled. We gave them a check as a deposit, but Eli let us know that until the City's permits were in hand, no money would be deposited. Once the permitting process was complete, work went fast. We completely moved out and 5 months later, we were back in a BRAND NEW HOME! We did have a bit of a delay during the project waiting on the City inspectors, but the communication between us and Alter was constant. We felt very comfortable calling or texting and Eli was always available and he treated our home with special love and care as if it were his own. Eli is a perfectionist and is always the first to notice if any little thing is off and is quick to reply with, "I'll fix it!" or "I'm on it!" and he is! The end result is stunning, we have so much more space, our bathrooms are gorgeous, the exterior is perfect and EVERYTHING inside and out is new and improved! We really formed a nice friendship with Eli and Cynthia and miss not talking to them as regularly as before. They are amazing, honest and trustworthy people who really care about you and want the best for you. They are more than happy to help your remodeling dreams come true. read more

Alter Construction has been wonderful! I had hole damages from snow storm and squirrels chipping it away around it (one very big including 3 sidings). Had holes closed/covered temporarily . Contacted 3 contractors (including ABC Home and Commercial services) , all contractors told me as sidings in my house not available anymore on the market, they could not keep esthetics of the house. They said would cover the holes in the back with new sidings and not take down the original sidings and re-placed them ("That is the way we do it now"). After 1 year of searching, I contacted Alter Construction. Eli, owner-PM, not only promised me to resolve these issues, but he would keep esthetics, so important to me. He found a material that resembled my original sidings. When his crew had already repaired properly the front, but the T groove was not aligned (because of the different material) asked his crew to tear down, and found a way to cut the new sidings in a way that would match the measurements of previous sidings. Called me outside and checked with me if I liked alignment, they nailed new sidings after my ok. If you look at the house, you do not see the new material at all, or any misalignment with the rest of the T grooves. The sidings of the front windows look aligned, symmetrical and pretty perfect. Same in the back, where they replaced all the first sidings row. They had already painted the house, and I noticed, for the first time and not included in the work order, a siding in the back that seemed old. Eli told me not to worry, his lead crew came next day and took it out, cut new material sidings, replaced it and painted again. No difficult discussions, just Eli saying " We want the client happy, we are here to make it happen!" Yes, I would suggest this company. read more

Highly, highly recommend! Alter Construction rescued us in a true time crunch. Exceptional integrity, detailed communication, and quality workmanship. We're SO happy!! The Problem: Our first baby was quickly on the way, and we were at a loss with our primary bathroom. We had searched for months for a quality contractor with fair pricing. Several shady contractors ran valuable time off the clock. We were getting increasingly concerned that we would be bringing our first child home to chaos and construction dust. We needed someone who could jump in quickly and would be extra sensitive to our health needs. We also needed to be able to trust them to show up, tell us the truth about our project and get the job done in a high quality way. Oh, and stay within the agreed budget. A VERY tall order these days!! Enter Alter Construction: From the very beginning, Eli Malkin impressed us with his personable, quick but in-depth assessment of our needs. He and his team respected our home, our vision and our time. He was honest about the timeline & budget - it would take considerable coordination to get things done the way we wanted before our daughter arrived. (They completed the project a FULL TWO WEEKS EARLY!) Eli handled everything. Alter Construction gave us such peace of mind. They allowed us to focus on our health and actually enjoy the birth of our first child. And our bathroom shower LOOKS and FEELS incredible!! What an awesome post-partum gift. Alter Construction made a potentially disastrous situation a breeze. We will always be grateful to Eli for his excellent work ethic, customer centric attitude and integrity. Go with Alter Construction if you want quality!! read more

We decided to close in an open game room upstairs. We had several contractors come over to provide numbers and scope for the project. As someone who is in the design/build industry you expect a certain level of service and knowledge. All the contractors minum Alter spent a grand total of 20 minutes looking at the project. Alter spent an hour looking at the project and going over various options and plans. Alter took measurements, pictures, videos of the area to remodel. While also presenting pictures and videos of previous projects. We are a firm believer in you get what you pay for. Alter's proposal for the project was 10 pages compared to the 1 page proposals from other contractors. Alter laid out the entire project scope, what is covered, what is excluded and expectations. During the project, Alter was at our house multiple times a day checking on the progress. What they said would get done for the day was done that day. The craftmanship was impeccable, and clean. We are forever grateful for Alter treating our home like their home. With the great work they did, we decided to excel another project to roll right after the first remodel. We wanted the master closet redesigned and they made it happen. As picky and precise we are as customers, there was nothing we noticed that had to be redone. Lines were clean and straight. They made both project match our dreams and desires. I will never venture out to hire someone else to work on our home. Only Alter will be the contractor to work on our home and feel like family. read more

We had an amazing experience with Alter Construction having our bathroom shower remodeled. There was a little bit of a rocky start to the process when selecting the materials for the work, my wife and I had never been through a remodeling project before and were overwhelmed with the amount and specifics of materials that needed to be picked out. However, after getting some help and a bit of hand holding we were able to get all the materials selected and construction set a date to start construction. The construction process was a dream. We spoke to Eli everyday during the construction process, he would give updates and explain in detail how things were going. When changes were needed, Eli explained the reason for the change and layed out all of the options as well as gave his personal recommendations. There was also a week that my wife and I were out of town (my brother was staying at the house) Eli called and texted everyday with updates and pictures of the work. During the construction process, the crew that was here working throughout the day was very polite and courteous. We are so extremely happy with the finished shower, we love it so much. I cannot express enough about how happy we are about the work that was done, the crew, and about Eli. I would highly recommend and am looking forward to reaching out to Eli and Alter Construction if we decide to have any more work done around the house. read more

We recently hired Alter Construction to replace and paint all the doors in our house, as well as to frame our TV cabinet, and the results were nothing short of spectacular! From the very beginning, communication with chef Eli was smooth and effortless. He was attentive to our needs and provided valuable insights that enhanced the final outcome. Scheduling was a breeze, and Eli kept us informed every step of the way. The team of workers was incredibly polite and professional. They arrived on time every day and were respectful of our home, ensuring that everything was kept clean and tidy throughout the process. Their attention to detail was impeccable, and their craftsmanship truly shows in the quality of the finished work. The new doors are beautifully crafted and the paint job is flawless. The TV cabinet framing adds a stylish touch to our living room, making it a focal point that we absolutely love. Overall, our experience with Alter Construction was fantastic. We are extremely satisfied with their work and would highly recommend Alter Construction to anyone looking for high-quality home improvements. We'll definitely be calling them again for future projects! read more

We initially contacted Alter Construction to get a bid on fireplace remodel. After meeting with Eli and explaining that our main concern was about fireplace leaking during heavy rain he presented us with two options: actual remodel (at a few thousand) vs re-caulking outside and repainting inside. We decided to proceed with a second option - his team found gaps in the roof/siding, re-caulked them and repainted outside and inside. They've done an excellent job - everything looks great, we already had few heavy rains and confirmed that they eliminated the leak and saved us some money. After that we contacted them for a slightly bigger project to replace siding on one side of our house (original siding from 1993 had some water damage). I also had concerns about other side of the house, but both Eli and his team pushed back and told me that it would be just a waste of money and they don't recommend it. Eli and Cynthia kept us informed about the project, explained extra scope that they uncovered after demolition and insisted on delivering high quality of their team's work. We are very happy with outcome of both projects and I would be happy to work with them again. read more

A Stunning Solution with Heart We reached out to Alter Construction with a unique challenge: we needed a safety barrier for the upstairs ledge in our home -- a 20-foot drop that had become a real concern after rescuing our blind kitten, who lost both eyes during the devastating July 2025 floods. Initially, we had something completely different in mind, but Eli from Alter suggested a glass partition. At first, we weren't sure -- but it turned out to be the absolute right choice. The 3.5-foot tall glass barrier is not only secure and sturdy, but it also preserves the open, airy feel of the space. It's sleek, modern, and blends in beautifully with our home's design -- a perfect balance of form and function. What truly sets Alter apart is their empathy, open conversation, and attention to detail. They understood that this wasn't just a construction project -- it was about protecting a vulnerable little life. Thanks to their thoughtful work, our kitten can now explore safely and confidently. We're beyond grateful! If you're looking for a contractor that combines craftsmanship with compassion, we highly recommend Alter; both Eli and Cynthia are good people! read more

Alter Construction has a great team that is on your side. They renovated our first floor after it was flooded from a water leak. Eli presented his plan and cost estimate, and stuck to it. More than that, he didn't nickel and dime us for anything. They painted a third coat on the ceiling without charging us. We really wanted the pantry replaced by kitchen cabinetry, but the cost was a concern. Eli saw how important that was for us and did not charge us for the demo of the pantry, the drywall repairs, texturing and repainting. He wanted us to have the kitchen we envisioned, and we are so grateful for that. His employees are responsible. Friendly and know what they were doing. Job site was clean and neat every evening. At the end of each day, Eli called us with a summary of what was done and what to expect for next day. They worked fast and finished sooner then expected. I personally never heard of a remodel being done ahead of schedule and on budget. They are a great team that cares about your family and your well-being. We are very glad we met them. read more

Eli with Alter Construction is an amazing GC to work with. My husband and I wanted to change out the the shower door and floor of our master bathroom. This was a small job and most GCs refused to do anything less than the entire bathroom. We spoke to someone regarding replacing the shower door and that person (Hero, with Shower Doors Today) referred us to Eli for the tile work. Eli was exceptional to work with. He spoke with us and told us step by step what to expect and what needed to be done, including any worse case scenarios that may arise. They began work within a few days. Luis, his main tile worker, was punctual and very respectful and worked efficiently and diligently. Despite not being able to use my bathroom for several days, this was an overall pleasant experience. We still need to get the door installed which will happen in a week but the tile work is beautiful and I can't wait to use my shower once everything is complete. Thank you Eli and Luis! read more

After trying to find a company that could do a full bathroom remodel, I found Alter Construction on google. I called them, and I spoke to Cynthia, we discussed about the project and it was so relieving. She gathered all the info, and scheduled the meeting with Eli the next day. Eli came and explained me in extreme detail about he bathroom remodel, and educated me about the building codes. He was super nice and easy to talk to! He always had amazing ideas how to get the best value for the money. Eli was coming everyday to the job site, to check the progress, and letting us know what was happening everyday and told us what will be the schedule for the next days. I felt like he always was there for me and my family, always cared that the jobsite was clean and safe! The result of the remodeling was unbelievable! My wife and my self are so happy! Thank you Eli & Cynthia for making this project so nice and easy! read more

Started with a project to turn his and hers "walk-in" closets in master to a single walk-in. While we switched from one rep to someone else we were worried we wouldn't like them as much- my wife was comfortable with the woman we had been dealing with and we were jazzed to move forward. As it turns out Eli at Alter has been wonderful, he's been straightforward and honest and kept communicating through the process and each stage of the project work. We expanded scope to do new matching doors and new fans for the rooms of the house, and the estimates and contracts were detailed and he went over everything to make sure we had no unanswered questions. Workers were always on time, or we had advanced notice for rescheduling when supplies were delayed. Looking forward to continuing to work with Alter! - Matt read more

Primary bathroom ceiling leak required immediate attention. After four contractors failed to respond (job likely too small), a neighbor referred us to Alter Construction. They inspected the roof just before a major ice storm, identified the issue, and installed a temporary patch to prevent further damage. After the storm, their team completed the roof repair, provided photos, and left the worksite spotless. They also repaired and repainted the interior ceiling and wall, carefully matching the original color. The owner and crew arrived on time, explained each step, and obtained our approval before proceeding. They honored their quote without pushing unnecessary upgrades. As seniors on a budget, we greatly appreciated their professionalism, transparency, and quality workmanship. Highly recommended. read more

Done a handful of jobs on the house through different contractors and this company is easily the best one. He will help you every single step of the way. Starting from walking you through the house, selecting materials at the store, suggesting opinions/input, constant updates throughout the whole process, and even finishing touches that are outside of your project. He fixed a patch on a carpet that was outside of his work. He did baseboard work that was outside of his area that happened to connect to the living room. His ETA for the project was spot on too. It's insane how much detail and work ethic Eli and his company has. My wife and I love him so much that we are legit planning another project with him in the future. 100% recommend. I don't normally post reviews and I just had to for Eli. read more

I needed a remodel for my new investment home because it was definitely outdated, the bathrooms, bedrooms the kitchen needed a lot of work. After a lot of research for a contractor, I found Alter Construction and I saw that they had a really nice reviews, so I call to set up an appointment and next day Eli came to see the job. I instantly felt comfortable with him. He is very knowledgeable and he explained me all the process for me to know what to expect. Once the work started I notice their crew cleaned every day before the left, and Eli told me the schedule and sending me pictures of every stage of the work. So I can say I had a very smooth and very enjoyable experience working with them. I would absolutely recommend Alter Construction for your remodeling project. read more

I can't say enough great things about Alter Construction! Eli and Cynthia offered a reasonable estimate which they kept to, kept us informed, and helped me feel comfortable throughout. Eli was here daily to inspect the work done that day by his perfectionist workers. After a large water leak and plumbing repair, I needed all new flooring and baseboards, sheetrock repair and painting in several rooms and also had tile removed in kitchen, laundry room and bathroom and new vanity and floor tile in bathroom. we also had shiplap installed on one wall of two rooms. All the work done was quality. We are much more than pleased with the results! And to top it all off, we made some great new friends. Many thanks to you, Cynthia and Eli!!!

After contacting several companies for our home renovation work of extending laundry room and converting formal dining into a second office we were disappointed in the lack of communication and response and very high estimates and proposals. We fortunately came across Alter Construction which was amazing to work with! Eli and team did great and quality work, kept us up to date and informed on progress and any items that came up during the remodel with options on how to address them. Most of all they completed the work in time before we moved into the house. I would highly recommend Alter Construction and already have in mind future remodeling projects we will reach out to them for. Thanks Eli and the Alter Construction team! read more

We've worked with Eli since 2016 with several projects over the time. They helped us with projects such as renovating our four full bathrooms, building outdoor decks & fences, and installing new french door. He and his crews are simply amazing!!! And they have been an absolute delight to work with. We go back and forth between 2 houses in California and Florida. So we've truly believed that solid communications must be the keys to success in our projects. Eli has worked closely with us to maintain the highest standards of sensitivity, quality, value, and professionalism. The performance from his entire crew has been outstanding in every regard. We appreciate his effort and dedication to our needs. Highly recommended!!! read more

Alter Construction gave me 5 star results combined with white glove customer care! My garage had been crashed into, and it was in shambles. Both of my vehicles were stuck in that garage, and I was stressed. One day and a phone call later, and Eli and his team had gotten my vehicles out and they started immediately setting up a timetable for all of the other work. From there on out, I never needed to call Eli because he was always diligent in calling me to give updates, and every goal was completed on time. The work was done impeccably and it exceeded all of my expectations! I highly recommend Alter Construction, and the next time I need work done on my home I won't hesitate to call Eli! read more
