Window Nation Pittsburgh
Window Nation Pittsburgh
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.

Champion Windows of Pittsburgh
Champion Windows of Pittsburgh
With over six decades of experience and expertise, Champion Windows and Home Exteriors is one of the nation's leading home improvement companies. Champion transforms homes with premium-quality products that are designed, built, installed, and guaranteed by Champion. Every product the company offers - from new windows and sunrooms, to siding and entry doors - is built right here in the USA, backed by industry-leading limited lifetime warranties, and comes recommended by more than 9 out of 10 recent Champion customers.
"Install was summer of 2023 and shortly after our patio door started leaking profusely when it rained. They came out after several calls were made and did minor repairs. Low & behold, each spring since it continues to leak profusely. Calling for service & submitting the online service ticket has gotten us nothing but "crickets", no return calls. The time on hold for someone to pick up is soooo long! Buyer Beware of the warranty. Not sure they want to honor any work once you fork out $28,000.00 for the window and door install. I will reach out to the BBB to file a claim."

"At first I rated them a 5 but they had me put in a review before the job was even completed. They used old tarp from previous jobs. There were debris all over my bedding and furniture from the old plastic tarp. If they needed new tarp I would supply them. Who knows what the previous projects had in their homes. I didn't notice till after they left. Yes, you definitely will need to vacuum. Which I expected, but not having to wash all bedding and vacuum furniture. The windows look good, but it's so much cleaning afterwards. So when they say you'll never notice they were there. Was not true at all. One of my bushes in the front were also damaged and trampled on."

"I am very unsatisfied with my experience. I called the office to talk about my projects and get a quote on the jobs that I needed completed. We discussed all three jobs. The office said this would take a day and quoted me a price. They charged me money to hold my appointment date. A month went by, I had to call the office the day before the appointment to make sure that someone was still going to be arriving the next day. The appointment was scheduled to start at 8:00 am. The handyman came to my house at 12:45. He looked at the jobs that were to be completed and said that he could only finish one of them and asked which of the three I would like him to do. He went out to buy materials and returned back to my house sometime around 3:00. He never even fully finished one of the jobs. He left my house at 5:30 and I was charged over $1000. I was also charged for a gallon of paint that he never even used because the job was never completed. I asked if someone would be calling to schedule the work to be finished. He assured me that someone would be calling. No one ever called or returned."
