Customer Reviews

I had a ProVia entry door installed and everything went great from start to finish, from consulting with Ryan on options, to delivery and install (quality of work was excellent). And price was super reasonable. If they can get the product you want, do not go with the big companies. Window and Siding Source is who you want.

These guys installed new, energy efficient windows on my home this Spring. I couldn't be happier!! Had a small issue with one of the windows that left them and myself puzzled, but in no time they ordered a new sash from the manufacturer and fixed the issue. I am so pleased and will recommend these guys to everyone! Ryan, thanks for your patience with me too! LOVE my new windows!

Ryan and his team did outstanding work. Highly recommend The Window and Siding Source for any home exterior project.

Wow! If I had known my house would look so great and the process would be so easy I would have called the Window & Siding Source years ago. They took care of it all — siding, soffit, fascia, and gutters. Ryan was incredibly responsive, friendly and professional. The crew was fantastic too — they worked long days to finish the job quickly, but never left my yard or patio a mess. I definitely recommend them — we've been raving to family and friends.

We had all of our windows replaced about 15 months ago by Ryan and the team at Window and Siding Source of St. Louis. They did a superb job in the installation as well as the follow-up on a couple of sashes that needed replacing (due to manufacturer defect, not poor installation). I would highly recommend them for doing great work, being on-time and communicating well throughout the entire process.

My wife and I wanted to thank Window Source and the team — Ryan, Steve and Darrel — for the fantastic job they did for us. Replacing 12 windows in my house was one of the best things we did lately. Ethic, honesty, punctuality, excellent work and nice people. The quality of the windows was exactly what we expected and the price offered by Window Source, as a local company, was more competitive than the one offered by other big known companies.

Pat, Ryan and installers Daryl and Steve did a fantastic job from start to finish. Very helpful, answered my questions honestly. I have recommended them to friends already. If you want honesty, no high pressure, and great windows this is the company to use.

Patrick, Ryan and their crew did an excellent job on our siding and guttering. Once they got started it took less than a week to install. They cleaned up their mess and left us with a beautiful job well done. Thank you.

Worked with Pat and Ryan to get new windows and siding on our home. They were honest in what we should and shouldn't pay for based on our long term plans (didn't just up-sell us on stuff we didn't need to make a buck), they got the work done fast, and we couldn't be more happy with the service and quality of their work. I wouldn't hesitate to recommend them to any of my friends or family.

I had a ProVia door installed. The rate was fair and the installation was perfect. They did what they said they would do, which is hard to find. They set up plastic to reduce dust, spoke to me along the way to let me know of the process, and finished the job timely. NO PRESSURE — gave me time to make a decision. I am so pleased.

Patrick and Ryan from The Window and Siding Source were very professional in helping us to understand different types of windows and making recommendations. Totally solution focused rather than high pressure selling. The installers were fantastic, professional, courteous and extremely competent. Cleaned up each day. We are so proud of our new windows and have recommended The Window and Siding Source to friends and relatives.

This team was on time, easy to work with and very professional. Would use again.

Patrick and Ryan — what a great team along with fantastic work crew! Best price out of 4 other quotes, highly recommended and will refer them to friends!

I was in need of two exterior French doors. The Window and Siding Source was the cheapest by quite a bit. The doors came quicker than expected and the installation was flawless. My doors look amazing. As an added bonus, I had a piece of Plank Siding that was in need of repair. They came and replaced it even though they were not the original installers. I would highly recommend their services to anyone.

We had a great experience, the siding only took two days to complete and the guys were fantastic. If there were 10 stars I would give 10.

They were diligent and called a few times when we were originally collecting siding replacement bids from a few companies. Very courteous and friendly, knowledgeable as well. Speaking with them now about possibly replacing a window.

Great guys to work with. Started the project on time, finished on time, and paid attention to the details. Great experience, so I have already contracted with them to work on my next project.

I had a fantastic experience with Pat Pimmel at The Window and Siding Source. There was no pressure from him to choose their product. The install was just as great of a process and our house looks AMAZING!! Ryan and Pat both came out the next morning to move the materials to the side of the house for us. Very impressed by this.

Everything went smoothly and came out great. Thank you Patrick for making this a wonderful experience — our house is now a beautiful home, thanks again.

Patrick and Ryan were incredible. Excellent price and work. I Highly recommend.
