Don't take our word for it — hear theirs
“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. 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 for their promptness and professionalism.”
“Full roof replacement done in a single day. The crew showed up on time, protected the landscaping, and you couldn't tell they were there when they left — except for the beautiful new GAF roof.”
“We had our entire home re-sided and the difference is night and day. Rob walked us through every color and profile option without any pressure. Fair pricing and truly excellent workmanship.”
“New seamless gutters and guards installed after years of overflow issues. Clean install, great communication, and the first heavy rain proved it out. Would hire again without hesitation.”
“Replaced nine windows throughout the house. Our heating bill dropped noticeably and the house is so much quieter. The team was courteous and cleaned up every single day.”
“After a bad windstorm Rob came out the same day, tarped the roof, and helped us document everything for insurance. That kind of responsiveness is rare — genuinely grateful.”
“Honest advice is why I'll keep calling Hammer Exteriors. They told me a repair would hold instead of upselling a whole new roof. Two years later, still bone dry.”
“Siding, trim, and gutters all done together. Detail work around the dormers was flawless. The GAF Certified Plus designation isn't just a badge with these guys — the quality shows.”
