Testimonials

Mark Geragos – New Berlin

The new window installation was neat and tidy. I was very impressed with how well everything went. As far as home remodeling goes, this was probably the best experience one could ask for.

Rachel Chesler – West Allis

I would highly recommend Custom Trim Inc. for siding and window installation. The work crew was highly professional and really fast. They were great and my husband and I were so pleased with the results.
