“Nathan and Eric were at my home today replacing a rotted-out garage service door for us. They were here for about 3.5 hours, and let me tell you, I am impressed. They did an awesome job; the door looks so clean, and it’s finally safe. They were so kind and courteous and took the time to review the project steps beforehand and everything they did after it was done. I will recommend TightSeal Exteriors & Baths to anyone needing work done. Thank you so much!!”
