A Customer in Springfield, VA

Griffin was not the lowest bid but was honest about all of the potential conditions that could increase the price. The quality of the work was first rate, and he was very good about keeping me informed about progress on the job throughout. He took pride in using high-quality materials and completing work of the highest caliber. Griffin inspires confidence in their work. I would not hesitate to recommend him to anyone.

A Customer in Bethesda, MD

The two-person crew was very efficient and proficient in moving from task to task — slate replacement, woodwork, and gutter replacement.

A Customer in Chevy Chase, MD

Matt Hoffman was very easy to work with. His attention to detail in estimating and performing the work was exceptional.Carlos was team foreman. HIs work and supervision in shingle, slate, and copper was top notch.

A Customer in Chevy Chase, MD

I was certainly impressed with the estimate of the quality work that Mr Hoffman provided. For example, he pointed out that Griffin would only use new copper in all of the valleys and flashings. Also a key reason for choosing Griffin was Mr. Hoffman’s guarantee of a 10 year warranty on the workmanship.

A Customer in Washington D.C.

In replacing facia boards, copper gutters and downspouts, and roof slates, the crews demonstrated true craftsmanship and were always neat, friendly, and polite. Besides Matt Hoffman, the team leaders were able to give competent advice.
