Discover why we are becoming the "Go To" Door Service company in the Valley of the Sun.

Call Principal Door Service the next time there is a door problem of any kind and you will learn why many restaurant chains, facility maintenance companies, general contractors, property managers and home owners make Principal Door Service their first and only call.  So trusted in the industry, many of our referrals come from area door manufactures, locksmiths, current clients, and even other service companies when faced with an unfamiliar door problem.

Principal Door Service Inc. is an offspring of Principale Door & Hardware of Western NY, where founder Russell Principale started in the 1950's and became known in that region as "THE" industry expert.  Russell not only trained his two sons in the family business but most of the quality door men in the area.

Son David has brought that tradition of quality workmanship to the Valley.
