"The Hammer Exteriors team was wonderful to work with! We had 3 exterior doors put in — 2 glass storm doors and 1 fiberglass front door. Rob was excellent at communicating with us each step of the way to ensure ordering, delivery and install all went smoothly. Even when they encountered something unexpected during the install, they handled the situation promptly and efficiently, and our project was not delayed. Our cats are very pleased with their new doors (and we are too!) We would definitely use Hammer Exteriors again for our next home improvement project!"
"Our skylight started leaking after 5pm on Tuesday evening, I reached out to Rob Kurzner of Hammer Exteriors and within moments he was already figuring out when to come out to assess the damage and repair it. By the following Wednesday my skylights were replaced and the other problem areas of my roof were fixed. Highly recommend Rob and his team at Hammer Exteriors for their promptness and professionalism. Rob clearly cared to fix our roof ASAP and made sure it got done properly!"
