“Valdicass installed new windows at my house, and my wife and I couldn't be happier. The quality of the windows are great. Their communication, installation and sales team were really excellent to work with. Their cleanup was also excellent. They arrived on time and completed the job in a shorter timeframe than I would have expected. I would definitely recommend to anybody!”

“From our first meeting, we knew Valdicass was better than the other teams we were getting quotes from. They took far more measurements and called out small imperfections and problems with the house that may be an issue, which the other companies hadn't even noticed. Our new doors and windows are already making a huge impact on our winter energy bills, and the whole team did a wonderful and meticulous job!”

“I have worked with Valdicass in the past with windows in a prior home and was so pleased that we used them again at our current home. The installers arrived on time and got to work right away. They were also very professional, took care of my furniture very well, and left everything clean after they were done. It’s been over a month since the installation and the windows are working perfectly and look great too. I recommend Valdicass for your next project as you will not be disappointed.”
