"The previous owner I bought the house from concealed the rotten windows and the home inspector my realtor recommended did not mention that the windows need to be replaced. 5 years later, water started to come into the house and I learned that not only I need windows, but my house susteined significant damage. I looked for a local company willing not only to replace the windows, but to fix the potential damage as much as possible. Not a same day or 2 days replacement company that will slap the new window in the rotten frame but someone willing to replace a rotten stud or seal. And I found Travis that made me an excellent impresaion- honest, knowledgeable and surprisingly, not pushy. After an initial quote I let it sit for about 2 weeks until I decided and except an email asking me if I have more questions...which I had -about 10 of them lol, he let me decide. In 4 weeks his team was already on site. Now his guys are the best. I had Adam and Rafal installing my windows and oh, my , when they opened the walls I was looking in disbelief at the rotten wood. They were able to replace all that rotten wood including wood studs, top and bottom seal, joists, etc and make the window casing look like new. Most companies either walk away or cover the rot but these guys were absolutely amazing. Every detail was adressed and every concern was answered. And I was not an easy customer because I was over concerned and watched everything they did, asking a bunch of questions. Yeah, that kind of a customer. What can I say. There are a lot of windows companies but these guys standed apart being able to handle this complex and challenging project. Highly recommended, a company that stands apart through the quality of work and professionalism."

"There were efficient, came as projected, did window replacement and screen door and were on their way. There was a screw missing on the screen door, but repairman didn't fix."

"We used Integrity Windows and Siding back in 2012 to replace our siding and half of our windows (one of the windows did break shortly after installation - it was quickly replaced at no cost, no questions asked). Fast forward to 2023, we again sought out Integrity and Howard to install some of the remaining windows. Howard is very knowledgeable, easy to work with, explains options, kept us informed during the process and sells a quality window at a fair price. Mike, who has been with Integrity for 20+ years, was very careful during the installation - clearly he knows what he is doing! The windows look great, work great and keep us warmer. We highly recommend Integrity and Howard for your next project. We couldn't be happier."

"Closed stuck windows. Now OK as long as these windows are not opened. Offered service to replace hardware on window for $150 per window. Decided not to do anything."

"Siding and Windows Group is a top not h company and we highly recommend using them if you are looking for high quality and honest work. We were in a special situation and Angelo was with us from the moment I placed a call to the company, until we were ready to move forward. His approach was no nonsense, no pressure, and that is because they want to do place you within the right product categories and at the right budget. We started with just new James Hardie siding but decided to add a new front door and a new rear patio french door. Could not be happier with the design and color choices. There is a reason this company is top rated and has a long list of references which they provide so you can drive and see the work yourself."

"Matt was amazing. He fixed my window in freezing cold weather at no cost and had it done in under 5 minutes. Super kind, efficient, and clearly knows what he’s doing. Really grateful for his help. Highly recommend!!"

"On 6/17/2021 your Techs Jose and Eduardo came to repair one of my windows in my family room. These two young gentlemen were extremely professional, polite, and hard working and made my window look like new. Based on my experience with them, I will definitely call Apex Window Werks for future window repairs and will highly recommend your services to others. Thanks for a job well done."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."
