At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

The windows are wonderful!

Everything from picking out the windows and door, to scheduling, to installation—it was so easy and flawless! The crew who did the installation were incredible! They showed up on time, were extremely friendly and professional, and worked very efficiently. They kept the house super clean while they worked, and cleaned up thoroughly when done. The windows themselves are high quality. We can already tell that sound and air is not coming in around them like before.

The installers went above and beyond on my new windows. My home is over 100 years old and not in a charming way. They encountered some problems that were unique to my home, but they did everything to overcome them. Pleasant, friendly and efficient.

We are pleased with everything from beginning to end. When I had questions they returned my calls and answered them. The windows were finshed and ready for installation when they said they would be. The installers were quick, efficient, courteous, and friendly. When they left I couldn't even tell they were here because they cleaned up so well. They also explained how the windows work when they were finished with the installation. The windows work well and look very nice!

My wife and I were very pleased on how prompt that Window Nation was from the very start with arranging an appointment for an estimate to the very end of the window installation. I would recommend them to people I know in the future.

Anthony Kempa/Consultant was very informative and explained the differences between all of the windows and how the efficiency would lower my electric bill. Keith/installer was very polite and swift. He was in and out. He explained the installation process and answered any questions I had. I would definitely recommend!!

The process from the qoute to completion was very easy. From Josh (sales member) to Sergio (job manager) this process was stress free. Josh was extremely professional and didn't waste my time by trying to over sell. He is very proficient in his job and knowledgeable in the product he is selling. Install for 15 windows, the team got done just shy of 4hrs. They left house and property as clean as it was when they arrived. I would use window nation again and would recommend then to anyone who asks.

"Thank you for your kind review; we are happy to pass along your comments to Josh, Sergio, and the team here at Window Nation Pittsburgh! Your recommendation means so much to us and we're thrilled to have earned it. Thank you again for taking the time to let the world know about your positive experience. Have a great day!"

Workers arrived toward the end of, but still within, the given two hour window. They did call before arriving, which gave me just enough time to get the dogs situated in a different room. Due to the age of my house, they followed lead protocols. This included a deep cleaning of the floors near the windows plus other things I didn't really follow because I stayed away. The project took about 7 hours to complete. I don't know how this compares versus the average, but I didn't feel they were rushing or wasting time. When they completed, the foreman explained the lock orientation and showed me how they fold open for cleaning. Inspecting the windows and the sliding door, I found nothing wrong with the workmanship. I will look to work with Window Nation first if I decide to replace more windows in the future.

Installers (2) arrived on time. Rechecked the measurements of each window. Started quickly to install windows with one worker inside and one outside. Very professional work. Cleaned up inside and out, removed old windows, fabricated outside covering, and re-caulked. Completed in about 5 hours, including lunch break. After installation, we did a walk through and inspected each window. We are happy with the design and operation of the windows, however, disappointed with the screen design. The screens do not fit tightly and sag in places when viewed from the side. Delivery time was longer than expected.

Replaced original windows on our rental property. I was very impressed with the our Sale Rep Chris and the installation team was great. The communication was great, the windows were a little late due to supply chain issues but Chris kept us informed. The Installation team did a great job installing and clean up was good. I would use Window Nations again.

Our electricity worked when they got here and did not when they left. They acknowledge they are the cause but refuse to fix the problem. Told quote "call an electrician". ******* terrible!

The installation went wonderfully, very smooth with no issues. The installer was a one man dynamo! He easily removed each old window, prepped the window frame and installed each new window with ease! He was very conscientious and kept everything clean. He answered all our questions and addressed our concerns. Thank you to Window Nation and their installer! We would definitely use them again...
