What People Say About Us
Andrei and his team are top- notch. They keep you informed throughout the process from purchase to manufacture, to install. They were able to move our installation date up and his team was thorough, respectful of our property, clean, courteous and professional. This is the second time we’ve used them to replace windows and we’ll continue to do business with them again.
Very, very satisfied with Andrei and his team. They were so professional, polite, and were very detailed with their install of my windows and patio door. Everything was so clean after they left you wouldn't even know they had been here. Andrei stopped by after and inspected every thing to make sure all was right and to be sure I was satisfied with all. I will not hesitate to recommend them highly to anyone wishing to upgrade their home. Thank you Sidings & Windows Wizard LLC!!
We highly recommend this team at Sliding & Windows very professional, responsive and on time. Andrei was great pleasure to work with and was available for support through entire cycle and post installation support. He has great technical knowledge about different type of windows and installation process. Installation crew was very professional and finished the project on time, they will always consult you before making any decision.
The team at Siding & Windows Wizards are amazing. Super friendly and knowledgeable about their products. Installation was done quickly and without issue. I would highly recommend these guys for any window installation. I had basement windows installed and I could not be happier with the results!
