The initial estimation visit was the best such experience I had so far – to the point, reasonable choices, helping me set priorities on pain points, select models based on my requirements, explained new technologies with pros and cons, offered the option to repair instead of replace where applicable, and set a requested installation date.
Installation itself completed smoothly, no impact to the rest of the house, very clean and thorough work, they answered to questions and let me inspect the work at the end.
Would definitely recommend and will hire Loyal Seal for future work.

Tried to get another well known and advertised company to come out and give me a quote but they never called back. Loyal was there in no time to give me an estimate and we signed a contract. Work was done on time, neat and appears to be of good quality. I am totally satisfied and as a footnote the installation contractors had no problem with me hovering as they did the work…lol

Gave us fair price, had windows made within 3 weeks and installation was done in one day the guys cleaned up after and took all old ones away great service

Amazing company! The quality of the windows and doors are good
Would highly recommend it to anyone who is looking to replace or upgrade their doors or windows
