Testimonials

Henry was very responsive and the repairs his crew did went above and beyond my expectations. Would recommend to anyone needing home repairs or improvements.

Heather Sylvis

Henry and Mike was great to work with. Henry’s initial observation of the damage for my roof was spot on. Mike and the team came out and did a great job replacing my entire roof in 1 day. I would recommend them to anyone who needs roof work.

Nathan Brown

Absolutely love the efficiency and quick response I received from the company. The same day I called they had someone come out and give me a free estimate!

Malaka Hasz

I am more than pleased with the service that Daniel and the GRB team provided us here at Riverdale Baptist church. They were able to provide us with everything we needed in a timely manner and always seemed to be available if we had any questions. Overall, we were very happy with the overall experience and would definitely recommend them to others in our community.

Our Core Values

Reliability

If we say we will do something, we will do it. If we say we will be there, we will be there. Too often this isn’t the case, and it’s a non-negotiable for our team in all the projects we do with each of our clients.

Attention to Detail

The details matter, not just aesthetically, but functionally. Our team takes pride in the details of their work, seen and unseen. We believe that the quality of our work speaks for itself, and we’re confident you’ll agree.

Responsiveness

We know that it can be difficult to undertake big projects. We also know how frustrating it can be when companies don’t respond. Our commitment is to be responsive before, during and after your project is complete.
