J&S General Contractor is a family-owned and operated exterior contracting company based in Derry, New Hampshire, serving condominium communities, homeowner associations, and professionally managed properties throughout the state led by Tom Galusha.

After years of working for traditional contractors, the company was founded to address a common problem in the industry: a disconnect between promises made during planning and the work delivered onsite. Too often, property managers and board members spend time outlining expectations, only to have projects handed off to rotating crews unfamiliar with the scope, priorities, or standards required for multi-unit properties.

What You See Is What You Get

With Granite State Contractor, the contractor you meet is the contractor overseeing the work. Projects are managed directly, with hands-on involvement from start to finish. This approach ensures continuity, accountability, and a clear understanding of each property’s needs—especially important when working within shared residential communities.

We work closely with HOA boards and property managers to coordinate exterior projects efficiently, minimize disruption to residents, and maintain clear communication throughout every phase of the job. Our experience with association governance, approval processes, and long-term maintenance planning allows us to deliver dependable results without unnecessary complications.

Focused on Exterior Systems That Matter

Granite State Contractor specializes exclusively in exterior construction and maintenance for condominium and HOA properties. Our work centers on building systems that protect structures, support safety, and preserve long-term value.

• Deck repair and replacement for shared residential buildings
• Siding repair and replacement
• Roofing repair, maintenance, and replacement
• Exterior maintenance projects for multi-unit properties

By maintaining a focused scope of services, we provide consistent quality, realistic project planning, and results that align with association budgets and expectations.

Built on Accountability and Long-Term Relationships

In an industry where follow-through is often lacking, Granite State Contractor emphasizes responsibility, transparency, and reliable execution. Our goal is not one-off projects, but long-term working relationships with associations and property managers who value dependable exterior care.

If your condominium community or HOA is seeking an exterior contractor who understands shared properties, communicates clearly, and stands behind their work, Granite State Contractor offers experience you can rely on.
