Serving you since 1971.

We serve Hamburg & Erie County.

A company that believes in great service.

Here’s what sets us apart.

Founded in 1971, Duffett has been a locally trusted company for decades. In those years, we’ve seen a lot of changes. The technology, people, and the tools of the trade are all different. But, here’s what hasn’t changed: we’re still the same company we were in 1971 when it comes to how we treat our customers.

Great customer service is the cornerstone of how we run our business. It always will be. Generations of families here in Hamburg have trusted Duffett with their home service needs.
