We hired K&J to replace all of our old 1960 single pane windows on our house after a consultation with Tony. My wife was home alone to receive quotes from about 5 different contractors. My wife felt comfortable with Tony and his personality definitely helped sell the job.
In my communication with Tony after the initial consultation and quote, he was very quick to reply every time to every question and helped come up with some different options for one of our larger windows.
K&J was not the lowest bid but Tony's service and their reputation led us to go with them. The only negative was the length of time between the purchase and the installation which isn't their fault, it is due to the manufacturer, but it was about 4-5 weeks we had to wait.
The installation team led by Nick was awesome. I was home that day and their crew knocked out the install in about 4 hours for 6 windows. Nick is a great foreman and kept the job moving and was also teaching and coaching some other installers as they went which was cool to see.
Some brick crumbled from the old window nails being removed which they quickly patched and repaired. The windows look great and the whole time they kept covering flooring and furniture where they were working to avoid making any messes. Nick even offered to use our vacuum to make sure there was no glass left in the carpet from one window they had to bust out to cut the frame (since they only had a shop vac which wouldn't quite do the job). Super polite and went above and beyond with his team. I would recommend K&J and will be having a door installed by them shortly as well!
