Custom Molding Solutions

The type of molding you use on a job can make the difference between an ordinary finish and one that gives every room a quality feel. We can make custom profiles to your specifications, with special orders for many wood species including poplar, oak, mahogany and cherry. Moldings are offered in widths up to 12” and interior or exterior priming can be applied in our shop.

Custom Millwork

Deciding which millwork is right for the job is not easy. No matter how intricate the design, we can help ensure its proper production and fit. We will advise you, providing customer support every step of the way that the product fits and performs as intended. We can check to make sure installations are proper. We can even make a template for your custom windows. This frees up valuable time for you to attend to other important matters.
