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.

What a positive experience during recent renovation project. The sales and installation were done in a timely, accurate, attentive way. I was impressed with the personalized attention I received from an evening call from telemarketers; the sales rep, Dan, that provided the quote; the scheduling and booking department; and the installation crew that did the field work flawlessly. Would highly recommend for windows replacement and plan to use Loyal Seal again for patio door and front door replacement next year. Thank you so much guys.
