Salesman Phil Gardner was a no pressure wealth of information regarding our choices and we cannot say enough about our lead installer Mike Loving and his entire team who installed our windows over three days. They worked with baby and toddler nap restrictions, work from home occupants and did it all with a smile on their faces! Mike even took time to show me his secrets for the best caulking job I have seen!! Overall, A great group of professionals committed to making our window purchase and installation easy snd pleasant!“

“From estimate to final cleanup, Regal was professional, courteous, punctual, and an overall great value. Regal's work is top-notch, but where they really shine is in customer service, specifically communication. There was never a time that I did not know where in the process we were, what was happening financially, or when work would begin and end. I will contract with them again for future renovations and repairs.“

“Nathan's did a tremendous job installing new windows and siding on our home. Our home truly feels brand new. They took the time to understand our needs and provided great recommendations. A special shoutout to Lee and his amazing crew. Lee was super communicative and professional. The install crew did quality work, cleaned up thoroughly, and were very respectful of our living space. Could not recommend Nathan's enough. Thank you!“
