Window Installation reviews across the US

We had 5 lower-level windows and a set of sliding glass doors replaced by the Window Source. Even though the installers - Ray and Andrew - were working on a very cold day - mid-20's for the high - they still did an excellent job. They were very courteous and professional and paid a great deal of attention to detail. We can't believe that they got all of it done in one day. They kept all areas clean throughout the process and were very easy to talk to and were very respectful. I highly recommend the Window Source and those two installers.

This was our second time using window source. Last year we replaced our basement windows and felt a difference. This year (January) we did 7 windows and our front door. Bob and his crew called first thing in the morning to let me know that they were on their way. It was a crew of 4. They worked together like a well oiled machine. Everyone knew their jobs and got right to it. Prompt, curiosity and polite. Completed the install in 3 hrs. We had a small issue with the door handle. They came back the next morning to get the handle on and installed the put in the new threshold. I had a few questions. Bob took the time answer them. All of the staff is Amazing. From Wayne who came out and helped us pick windows and give us our quote . Rick the owner coming out to measure to make sure we had the correct size. Aleea in the office making the appointments, follow up and payment. And of course Bob and the boys for install. Highly recommended.

We ordered a new bathroom window, two kitchen windows and a bay window. They told us they would arrive between 8 and 9 AM, and arrived shortly after 8 AM. Each window had its own crew to do the installation and the team worked together very well and efficiently. They were like a well oiled machine and finished the total job in under four hours. They even left the area cleaner than how they found it before installation. Each crew member was very respectful and polite, and I would 100% hire them again to do future window installations should we require it in our home. I truly believe that anyone who wants to hire them for work on their own home can rest assured that they will receive wonderful service and great products.

We had Window Source RI come and do our front window. From the quote to the job being done was simple and easy. They did a wonderful job. Everyone was friendly and professional. I love my new windows.

Had Window Source replace 11 windows in our home. Installers, Bob and crew, arrived on time, were courteous and professional and completed the project in less than 2 hours. We have already noticed a big difference in the noise level and expect to see a big difference in our summer and winter electric bills. Highly recommend The Window Source.

This company is amazing. Not only are their prices reasonable, the professionalism of their installers is superb. They were fast, clean and friendly. I recommend the Window Source very highly!

We recently used Window Source RI to replace our outdated, 4 panel crank out window. From the moment of contact through the design, measuring, ordering to install process was exceptional!!! The customer service through this family owned operation was like working with actual family (minus the headache 😂) and attention to detail was given from beginning to end. During the install, they were constantly updating me in the progress and ensuring everything I requested in our new windows was correct. Such a polite and warm team to work with. From the start conversation/quote to the end clean up, everything was top notch and will recommend Window Source RI to any and everyone looking for new/ replacement windows! Our new window looks like it was always part of this home- thank you!

This company did a great job on the our windows. The customer service is excellent and the staff is professional and respectful. We had Joe P, Freddy and Dave in our crew and they were on time and worked together seamlessly and efficiently! They didn’t even take a break- just got the job done! They cleaned everything thoroughly and you wouldn’t know they were there. Took extra time to add moulding around the windows for a neater job. The windows are great quality and look fabulous. I will recommend this company to everyone.

I just got 8 windows installed this morning. Bob and his crew were excellent. They were all very respectful. They did a wonderful job in less than two hours. I was amazed. The windows look awesome! I would highly recommend this company! Thank you to all of you!

We got all new windows in our house today by The Window Source and I gotta say, the team showed up when they said they would and took exactly as long as they said they would and left the house in great condition (as in didn’t leave a mess behind). They were professional, kind, and clearly very experienced. Within an hour of them leaving our house feels cooler and quieter. I couldn’t be more pleased. Highly recommend. Great local company. Great local service.

1/23/2026 Bob and his crew did an excellent job installing our new windows. We had a HUGE 5-paned bay window replaced, a 4-paned bay window replaced with 3-doubled hung windows, and a 3-paned crank out window replaced with 3-double hung windows. They all look beautiful. Bob and his crew worked together seamlessly and left everything neat and clean, inside and outside. Thank you so much! Tom & Wenda

Bob and crew from Window Source were great to deal with and were a well orchestrated team. They did an excellent and efficient installation job and were courteous, clean and informative in showing the operation of the new windows. Everything was done right with no issues and we would highly recommend Bob and his crew to others!
Nice product and great job guys 👍

We recently had all the windows in our home replaced by Window Source RI, and the entire experience exceeded our expectations from start to finish. The quality of the windows themselves is outstanding, but what truly set this company apart was the incredible installation team led by Bob.

Bob and his crew were the definition of professionalism. They arrived on time each day, communicated clearly about the process, and treated our home with genuine care and respect. It’s not often you come across a team that is not only highly skilled, but also so friendly and easy to work with. They made what could have been a stressful project feel smooth and even enjoyable.

Their attention to detail was especially impressive. Every window was installed with precision, and they took the time to ensure everything was perfectly aligned, sealed, and finished. They didn’t rush the job—instead, they focused on doing it right. You could tell they take pride in their work, and it shows in the final result.

Customer service was top-notch throughout the entire process. Bob and his crew were always happy to answer questions, explain what they were doing, and make sure we were completely satisfied at every step. They also left our home spotless at the end of each day, which we really appreciated.

If you’re considering replacing your windows, I can’t recommend Window Source RI highly enough—especially if you have the chance to work with Bob and his team. Their professionalism, friendliness, and commitment to excellence truly make them stand out.

Window Source was a great experience. Replaced 9 windows. Very professional, and polite. Job was done in a day. Reviewed the particulars of the new windows. Explained paperwork on windows guarantee. No mess left. Cleaned everything up and took away.

Great people to work with. We went through Mass save and they were very patient and understanding and made it happen for us, including applying for the rebates afterwards. Bob and his team installed our windows( 12 bedroom windows) and they we on time, fast and efficient. They even kept an eye on my cats, who escaped the room I had them locked in and let me know right away. Really kind and wonderful people; decent prices and quality work. We know who to call for our next set of windows we need to replace.

I had the Window Source install six basement windows for me, five hoppers and one dryer vent. Kevin and Cappy showed up on 7/1 as scheduled. They both did a beautiful job and were very personable. The dryer vent was a little too big, so a new one was ordered. Bobby and his crew showed up on 8/21, right on time to install the new one. They did a great job, and also were nice to talk to. Glad I had the Window Source install the windows for me. If the windows perform for me over the years as well as the installation went, I’m a happy camper. Highly recommend to friends and family!

I ordered a new slider and kitchen window. So pleased with my new windows! Anthony was wonderful to work with! Honest, didn’t feel scammed or pressured. Joe and Freddy did an amazing job with the installation!! Great team, great product!

Replaced original front door, patio slider, and custom picture window. Extremely pleased with the service from start to finish. Absolute professionalism from the service technicians. Our 4 year-old was super excited to have the "workers" in his house and they were great interacting with him and making him feel "helpful". Will definitely consider when we are ready to replace the remaining windows in the house. Would recommend to anyone! Thank You!

James and Zach came out today and installed our window and did a very efficient and fast job.

Eric came right over the same day i called to take measurements on my windows. Then i received the quote including all options. I chose the Great Lakes triple pane insulated eco window. Price and quality was excellent. Then Zack and James did an excellent job installing my windows. They were excellent and very proffessional. Their attention to detail was great. They took their time to be sure everything was done correctly. I would definitely highly recommend Vanderlaan. My windows look great!!!!

My experience is only from getting a consult with Dave and I was very impressed. We went over what I thought was an issue, he mentioned the best way to move forward. I’m very impressed and I will go to this company with improvements in the future.
