I've shopped for doors at many places in SF and Marin and gotten the "homeowner treatment" (not a contractor, not important enough for their time). Collier has been exactly the opposite, treating me like their most important customer from day 1. My sales rep, Julio, was knowledgeable and incredibly patient, the order went through like clockwork, and they've been responsive to every request. Marvin shipped a broken handle and quoted four weeks for a working one; Julio made sure we got it within the week. A month after the installation, the door started sticking; Julio was on it immediately and the receptionist at Collier called at least five times to make sure Marvin was taking care of us. I don't know what these other reviews are about, but I could not recommend Collier more highly - great selection of doors, great sales rep, great customer service. read more

In follow up. I had to hire an attorney spending thousands of dollars force them to replaced the doors under warranty. If you have 10,000 dollars to hold them accountable and can afford a year delay ,I'd use them. Otherwise, I wouldn't. read more

My first interaction was with Ernesto, Collier's sales rep. Ernesto patiently walked me through all the options and has been very responsive throughout the process. I chose fiberglass windows from Marvin. Collier's installation team were meticulous. I was really impressed with their commitment to getting all the details right. I'm very happy with the windows and will use Collier for my next project! read more

I used Collier through my contractor for ordering windows. Collier was the supplier for the high-end Marvin windows I wanted. Ernesto came out and measured--and also came back out at no additional charge to replace one of the screens that had come damaged. He was friendly and helpful and even offered to do a handyman type favor while he was here that had nothing to do with the job. I would use them again. And the Marvin windows I got are top of the line and were price competitive with another company that had given me a quote. There are several different types of window formats--and the sizing is very specific. You need to be able to trust your window supplier to know exactly what to order. Next time I would probably also use them for the installation. read more

Ernesto is the best! We had an issue with a couple of handles from our Fleetwood windows that were installed during our to-the-studs remodel in 2017. He reached out to the company on our behalf and secured replacements. He delivered the handles to our home himself and installed them too! No charge. Exceptional customer service! read more

Collier Warehouse has been very professional, reliable and courteous. I have been a customer since 1990's and highly recommend!

I am giving one star because zero is not an option. I have remodeled 4 houses and Collier Warehouse is the worst vendor I have ever encountered. I assumed it was a sales and ops problem, so I reached out to the owners multiple times and they can't be bothered to respond. The bottom line, their windows do not open and close properly and they do not honor service contracts. I used them 20 years ago and had a positive experience but do not fall for their current diamond certification status. Terrible company! read more

The front door they sold me was fantastic. However, two years later, the door started to sag and rub against the floor. Their customer service was great until they realized that there was no way for them to fix the problem because there was a defect in the hinge on the Fleetwood Pacific 3500 front door that they had installed. Each time they would fix it, it would be fine for a couple of weeks, then start sagging again. They claimed that the problem was with the floor. However, that made no sense, since the door was fine for two years, then for about two weeks after each service visit. Clearly, the door was sagging because my floor definitely wasn't rising. The situation dragged on for years. Eventually, I was told that the owner of the company would come out to inspect the situation, which impressed me very much. However, he never showed up and I never heard from them again. I think that they were just trying to get the statute of limitations to run out. I strongly recommend that you find a company that has unwavering integrity. Collier Warehouse is definitely not that company. read more

Collier did a great job replacing the windows in our office. Their installation crew was amazing and very friendly. They did a great job and it was done fast and beautifully. Highly recommended. read more

I'll prioritize that this is a review on trying to GET a service quote from this company. My husband reached out regarding a very large custom skylight that we need replaced on our home - Paul responded saying he would be happy to provide a quote if we provided pics and such, which we did right away and has since ghosted us. It's now been almost two weeks since then. I don't normally leave this type of review (services not yet performed), but it's an epidemic in the residential housing services industry here in SF and I'm frankly sick and tired of contractors and the like not having basic professionalism in how they communicate. When we research who to reach out to, as well as who we eventually work with, we read reviews and communication skills and ease of ability to work with someone is top of our list. So, sharing this for anyone else doing the same. I'd be happy to update this review if Paul decides he has time to respond to us. In the meantime, we have sought bids from two other local companies who we reached out to at the same time as Collier and they have not only responded and given us preliminary bids, but set up times to come out and assess in person for next steps. Given the great initial response from Paul, we were actually hoping he would have been part of this as they were our top choice. read more

Oh Yelp Master, may I give these people 0 stars? Please? Pretty please? They really deserve 0 stars. They're rude, they're way too many weeks late in my order and now they're solving the problem by simply not answering my questions. The lady that answers the phone has an attitude - seriously? Your job is to (a) answer the phone and (b) be polite. Can you really miss 50%? I should have read the reviews - too bad they're the only distributor for Fleetwood doors in SF. If you can stay away. read more

Everything went perfectly - I'd definitely recommend Collier to anyone considering. I spoke with Paul directly and he seemed like such a genuine, nice guy who really cares about his work. They wanted to make sure that I got everything I needed on my end exactly how I wanted it and worked hard to ensure it was all perfect. It was great to work with them and I'll definitely do business with them in the future. Thanks Collier! read more

We had to replace curved solarium windows on the fourth floor. Paul and Ernesto from Collier came, assessed the situation, and custom-ordered the curved windows from us. After the windows were shipped to their warehouse, they reached out to schedule an install date, arranged the scaffold contractor and sent a work crew who - within 1.5 days had seamlessly and flawlessly replaced my old windows, caulked and painted the new ones. Paul and his entire team took great care to be responsive and were very professional. We're grateful for their wonderful service and will gladly hire them again for any complicated window job in the future. read more

First, DO NOT recommend for window replacement. Wildly underwhelmed with the service here. We have a pretty large home we were exploring a window solution for: either glass replacement or inserts. After hounding our rep for numbers, we finally got a reasonable quote for inserts and a completely insane quote (90K not including scaffolding which we learned wasn't even necessary) We got 2 other quotes for the same job, one for 19K and another for 23K... Needless to say we won't be using the crooks at Collier for anything now or in the future. Even if their rep did return our emails or phone calls. read more

We were very fortunate to have chosen Collier Warehouse to guide us through the selection and installation of the windows and French doors when we built our new home. After 15 years we are still extremely pleased with how our beautiful windows and doors look and have performed. When we need a tune-up or adjustment, Collier's support is easy to schedule and the servicing is done by reliable, able technicians. I highly recommend using Collier Warehouse for anyone seeking knowledgeable salespersons, high quality windows & doors and outstanding service. read more

I ordered two velux skylights and was told they would be delivered on friday. On monday I called to see why they had not been delivered and was told they would not come in till wednesday, five business days late. When I explained that I had scheduled the work already Rick the salesperson said "what do you want me to do about it". I explained that he should have called me on friday(the day they where due) and told me of the delays. I will never order from an unreliable place with horrible customer service like colliers. Go to beronio lumber instead!!!!! read more

Joe Thomas at Collier Windows, Doors & Skylights is terrific. They have a great selection of super high quality products and their service team is first rate. Joe recently helped me on a custom job. He is a true professional, highly knowledgeable, courteous, super timely, great at follow up and making sure the job got done on time and on budget. I highly recommend Joe Thomas and Collier - they are great! read more

I am a General Contractor and have worked in the City for many years. I tried Collier on the recommendation of an Architect. This was a large project, around 40K in windows and doors. I wish I'd checked out the Yelp reviews beforehand. I have never worked with a more incompetant, disorganized and unresponsive company in my life. I'll spare you the details but take it from me run, don't walk from this business. read more

I wanted to send in my compliments to your crew who worked our window installation project at 96 Toledo Way in San Francisco. From the beginning they were professional, courteous and accommodating to me and our tenants. They didn't blink an eye when tenants had special requirements in moving furniture. They were also very conscientious in cleaning up after each unit installation and the building common areas. Bravo for a job well-done! Harlan Woodring 96 Toledo Apartments Resident Building Mgr. read more

Stay away. These guys are bad at their jobs and worse at customer service. After screwing up my custom window order, all they had to say was "too bad" -- no suggestions, no inclination to help (and I was staring down el nino with my house wide open.) The installer who spoke to the guy on the phone later described him as 'Almost rude' Do yourself a big favor and stay away from these people. read more

We worked with Jorge and his team to replace a old, cracked skylight and repair holes around the base of the skylight. Jorge was great to work with and helped make the process easy for us. The new skylight looks fantastic, the base they built looks extremely durable, and the guys patched up a couple of random holes in our roof that they spotted (so nice!). We couldn't be more satisfied. Thank you again! read more

This is the the worst customer experience I've ever had. To replace the windows at the front of my house, the Collier rep I worked with assured me a permit would only take a week or two (I specifically asked as we have a historic house in San Francisco I was concerned about this being a big time suck) and then the windows once ordered would take 5-7 weeks, and a day to install. This was in May, which seemed plenty of time until our baby would be born in November. I promptly paid in full which the Collier team processed immediately. It took 3 months for them to get the permit, with no proactive communication that entire time, only responses once I reached out following radio silence. Then another 3 weeks passed as they waited for the manufacturer to confirm the color matching - this was something Collier also neglected to mention from timelines in May. It's now September, they still have yet to order the windows, and just told me the manufacturer is now quoting 9-11 weeks from date of order, AND the cost has now increased by 25%. I understand there are some things out of Colliers control, however as a business, they should be explicit and not overpromise on timelines (realistically they should know how long a permit on a historic house will take, the color matching timelines, and explicitly communicate the risk of of manufacturer delays) -- timelines have shifted at least four times and never been proactively communicated. We will now have a newborn before the windows are replaced which is not ideal, after initiating this process with Collier and paying in full 6 months earlier. read more

Highly recommend Collier. Ernesto did a great job. high quality custom windows (18' window in one piece), skylights and frameless corner glass door. Will use them again in the future. read more

Would recommend them. Very professional. From the original salesperson who came to my home and explained the different types of skylights I could choose from to the followup and installation, I was very happy read more

Terrible service, including highly unresponsive reps. Installation quote was much higher than those provided by general contractors. In addition, price for windows and doors SIGNIFICANTLY higher than competitors. My advice: go to Beronio Lumber's showroom and get your own quote (don't ask your contractor to do it!). You will save thousands. read more

Sadly i've had two dealings with this company, one two years ago, horrible customer service, and then the 2nd this year. The only reason I've gone with them is that my contractor uses them. Late delivery without any customer service at all. When I call to check on status, they say, "I don't know it hasn't arrived" this was after two missing windows in our order for nine didn't arrive. Please be warned and don't work with these people read more

I contacted Collier to perform repair on some Millgard Doors that were supplied, but not installed by them, about 5 years ago (for the original owner of our house). I had another distributor try to do the adjustments that were needed and they just had no clue. The 2 techs were on time, professional, competent and did an amazing job repairing my doors so they finally function properly. They even left the glass, threshold and surrounding area cleaner than when they arrived. I couldn't be happier! read more
