Rob was incredibly prompt and extremely knowledgeable—he took the time to explain how gutters, roofs, and even solar panels work, which was both impressive and informative. His expertise really stood out. The crew was efficient and professional, completing the entire gutter replacement in just a couple of hours and leaving everything spotless afterward. Overall, a fantastic experience—I look forward to working with Hammer Exteriors on future projects!

Rob took the time to break down every aspect of the roof replacement, which I really appreciated as a first-time homeowner. His crew was ready to start just days after the contract was signed and they also quickly returned to take care of a minor issue I had following the installation.

I am super impressed with the professionalism of Hammer Exteriors . I had to get part of a fascia fixed which is when I connected with Hammer Exteriors . What made me opt for them over others is the responsive and in my conversation I felt (was also hoping) confident that they are better . Rob informed me about who will be at my place and per commitment Manny showed up to fix the issue. He fixed the issue . Clean work and handled the issue the same day. He was also gracious enough to help be flip my trampoline which was overturned due to strong winds . Great guy ! Would definitely recommend these folks for any project .

I reached out to Hammer Exteriors on Thumbtack based on excellent reviews here. My house had original gutters from 35 years ago and they were coming apart at the seams, some areas were bent and the pitching was out of whack in a couple of places. Rob got back to me promptly, came out to check my gutters and gave me some excellent options. Also, his pricing was the most competitive of all. I went with the bigger 6 inch gutters. The installation date was set and his crew showed up exactly at the promised time. Rob was there too. He stayed back until the work was done. It was quick and professionally done. I could tell the guys were professionals and knew exactly what they were doing based on how they went about it all. Everything was done right in the very first attempt. No adjusting post the fact, redoing some parts or any of that sort. They made the exact cuts, nothing was over or under. In about 3 hours, they were all done with taking out the original gutters and putting new ones in place including all new downspouts. They cleaned up after and left my property clean. Rob made all the final inspections himself and also did a final sweep to ensure no nails or metal pieces were left behind. It has rained a couple of time since then and everything works wonderfully well. I am very happy with the work and I know these gutters will last me a long time. I would highly recommend Rob and his team to others.
