Replaced all the windows in our townhouse. Reasonable price, windows came in sooner than estimated, and the installers were terrific. Highly recommended.

In January, my husband and I met with Jim regarding replacing 11 windows in our home. Jim was very friendly and knowledgeable and answered all of our questions. The quoted price was much lower than we were expecting. After letting Jim know we needed to talk the decision over first, he left with no high pressure sales tactics or attempts to guilt us or force us into signing a contract that day. We ultimately decided to go with Windows Pittsburgh and could not be happier with the experience. The windows were ready to be installed in about a month. The two installers were exceptional. Friendly, professional

Jim was an outstanding contact person for this business. He was a straight-shooter regarding price and quality. The installers did a great job and cleaned up the old window debris and disposed of it. I have zero complaints about this company and the job they did for me and my home. I highly recommend them and their products.
Thanks Windows Pittsburgh!

I called Windows Pittsburgh for replacement windows for my home in Bethel Park. From the first call to the finished product, Jim and his team were perfect. From the initial (no pressure) consultation, to the installation, to the follow-up to make sure the windows were installed as promised, I couldn’t be happier. If you are in the market for new windows in the Pittsburgh area, I would highly recommend Windows Pittsburgh!

We had 10 windows replaced this week and our house looks like a completely different house. I love it! The installer did an amazing job and cleaned up after himself as he worked. Our old windows were around 55 years old and well past their useful life span. The new windows open easily, don't leak, and look great. I would highly recommend Windows Pittsburgh!

I had procrastinated on doing the many things that needed to be done to maintain the quality of my home. I have a small ranch house built in the 50's. The time had come to tackle these issues. I knew I needed new windows, but also a lot more like a new roof and gutters. I searched online for companies and I came across Windows Pittsburgh that could do all three of these items. In can be a crapshoot when you chose a company from the internet, but after dealing with them, I have no regrets. Jim is the owner and you deal with him. He's honest, upfront and has integrity. Very knowledgeable

Windows Pittsburgh is the best! I had consulted with several window companies and Windows Pittsburgh was a great choice! The installation was awesome and the company saved me lots of money! My townhouse has all new windows and the sliding glass door in the family room looks like a brand new room! Several neighbors complimented on what a great job they did!

I don't think I could have been more impressed with Windows Pittsburgh. Jim was very courteous and friendly, patient and understanding ... basically an all around good guy. Prices were very good and the quality is top notch. The installation was a breeze! The guys were courteous of my toddler and my house. They cleaned up everything and hauled away all trash. Would recommend Windows Pittsburgh to absolutely everyone.

We we 14 windows replaced in our home recently. While our home is only 13 years old many of the windows were failing and we had moisture between the panes. We decided to just invest the money and replace them with a high quality replacement. We couldn't be happier. The installation went well and only took about a day in a half. So far we are very happy with them and hope they help with our energy bills some. Jim Montgomery handled everything from start to finish and always answered any questions we might have had.
