Where JDH Serves:
Maryland & Northern Virginia

Our headquarters is in St. Leonard — right in the center of our primary service area. From there, our crews work active jobs daily across Calvert, St. Mary’s, Charles, Anne Arundel, and Prince George’s Counties. For Northern Virginia, we run regular crews along the US-301 and I-95 corridors. You’re not getting a relay contractor or a crew dispatched from three hours away — you’re getting the same JDH team that works on homes throughout your county every week.

For our five primary Maryland counties, yes — daily. Our crews are in the field on active projects across Calvert, St. Mary’s, Charles, Anne Arundel, and Prince George’s Counties throughout the work week. For Northern Virginia, we maintain regular scheduled operations in Stafford and Prince William Counties. If you need an inspection or estimate, we can almost always get someone to your property within 24–48 hours.

Yes. JDH holds a Virginia Class A Contractor license. Our Owens Corning Platinum Preferred certification and HAAG credentials apply to every Virginia job, not just Maryland. You get the same 50-year non-prorated warranty backed by Owens Corning on both sides of the Potomac — it’s not our word, it’s the manufacturer’s.

Roofing is live across all our primary counties right now. Window replacement, siding, gutter installation, exterior door replacement, and attic insulation pages are actively being added county by county. If you don’t see a service page for your area yet, call us — we almost certainly serve your location and the page is likely already in production. Our phone number is (443) 241-7356 and we’re available 24 hours.

For emergency situations in our primary Maryland counties, we aim to have someone on-site within 24 hours of your call. Our HAAG Master Level inspectors document damage with photos and Xactimate reporting — the same format insurance adjusters use — so your claim process is as straightforward as possible. We’re a local company, not a storm chaser. We’ll still be here after the paperwork is done.
