Crew was prompt and worked efficiently
Crew was prompt and worked efficiently to complete window install to our expectations. Would rate higher, however; one out of the 18 windows be replaced was the incorrect size and had to be reordered. Due to this we had to wait an additional 4 weeks for the final front entry-way picture window to be delivered, which then required us to clean it after installation.

The installer were just awesome przmemek and yurii always kept our home clean and with very little clean up for us to do. The windows were installed correctly and foamed correctly and completely caulked the entire window and smoothed the caulk on all windows, we were pleasantly surprised how much warmer the house feels. We greatly appreciated the care the installer took in our home. 😁😁😁😁

Very good product at competitive price
Very good product at competitive price. The installers were a very good, efficient team and got all windows and patio door installed in one day. Very careful with tarps inside to cover work areas as well as cleaning up outside.

Disappointed
Sadly the first time our windows were installed they did not match our HOA requirements. We then had to start the ordering and installation process over again and eventually customer service stopped following up with us. An installation tech had to contact us to fix the problem. No compensation was given for this mistake or inconvenience.
The technician was wonderful but for a company that prides itself on communication and customer service I was disappointed at the lack of both.

We appreciate you sharing your experience. We regret that the initial window installation did not meet HOA requirements, and the follow-up communication was lacking. We're glad the technician was able to resolve the issue. We will use your feedback to improve our teams and practices moving forward.

Window installers have to work at a fast pace which I understand but that gives them no time to be careful. This is our home and we do not want extra damage done to the home.
