Start your next roofing, siding, deck, window, or door project with clear guidance from a reliable family-owned exterior construction team.

Rooted in Quality Work and Family Values

Since the 1980s, Glissans Mill Builders, LLC has proudly served homeowners throughout Hagerstown, MD, with dependable exterior construction services built on honesty, reliability, and quality craftsmanship. What started as a family-driven business has continued through three generations, creating a strong foundation rooted in hard work, personalized service, and long-term relationships with residential customers. Over the years, we have remained focused on helping homeowners improve and protect their properties with dependable roofing, siding, deck, window, and door solutions.

We started this business after seeing how difficult it was for homeowners to find a contractor they could truly rely on for exterior home improvement projects. Many customers were frustrated by poor communication, delayed timelines, inconsistent workmanship, and contractors that only specialized in one area instead of offering complete exterior solutions. We believed homeowners deserved a dependable team that would take the time to explain their options clearly, complete projects carefully, and treat every property with the same level of respect we would give our own homes.

Today, we continue that same approach with every project we complete. Whether we are handling roof replacement services, deck repairs, siding installation, or window and door upgrades, we focus on providing dependable service and long-term value for homeowners throughout Hagerstown, MD. Our team understands that exterior problems such as roof leaks, damaged siding, unsafe decks, and outdated windows can create stress and costly long-term damage when ignored. That is why we work carefully to deliver reliable solutions that improve safety, energy efficiency, comfort, curb appeal, and property value.

As a family-owned and operated business, we believe communication and trust matter just as much as the finished project itself. We work closely with homeowners throughout every stage of the process, from planning and material selection to installation and final cleanup. Our goal is not simply to complete a project. We want homeowners to feel confident knowing we completed the work correctly and built it to last.
