Phil, Joe, and others worked carefully and thoughtfully through exterior and interior work on my 1890’s row home downtown. I am so happy with all of the work that they performed, and would highly recommend their services.

The exterior finish on our fiberglass entry doors had faded significantly (detail photo on right), and we had a hard time finding a painter that was willing to refinish them until we contacted Frederick Painting & Supply Co. The Zimmermanns were meticulous in preparation, stripping the old finish, and applying new stain and varnish. They took extra care even while the doors were drying by placing a temporary barrier to protect them from potential rain. We are very happy with the result and would happily recommend them.

A beautiful finished project. They removed existing wallpaper, fixed a water stain, and painted. Looks almost brand new in a 36 year old kitchen.

It has been a pleasure working with Frederick Painting and Supply for the last 20 years.  Owning a frame home with sections constructed over 150 years ago, has its challenges.  Phil and Shawn Zimmerman and their team have provided quality work and professional guidance in updating, enhancing and maintaining our home.  They answer our calls, arrive as promised and treat our home as if it was theirs. Thank you!

Thank You for a great job!  It was a pleasure working with you.  We felt like you and your employees treated our home like it was yours.  You seemed to take pride in your work.  We really appreciated a great job.

Worked me in so once the electric was done, I didn’t have to wait.


Workers were quiet and efficient.  End result was amazingly well done and neat.
