Room additions, primary suites, sunrooms, and in-law suites built foundation to finish by one experienced, family-owned crew. We tie the new structure into your existing home so it reads as part of the house, and we put a free estimate in writing before we break ground.
When a house stops fitting your life, a growing family, an aging parent moving in, or just one too few rooms, an addition adds the real space a remodel can't. But an addition is one of the more demanding projects a home can take on: it starts with a foundation, ties into your existing structure, plumbing, electrical, and HVAC, and has to match the house that's already there. Gray & Sons Contracting builds additions foundation to finish for homeowners across Calvert, St. Mary's, and Charles County, handling every stage in-house so nothing falls through the cracks between trades.
The most common addition, extending a kitchen, enlarging a cramped family room, or bumping out a bathroom. A bump-out adds usable square footage without the cost of a full-size wing, and we tie the new roofline and siding in so it never looks tacked on.
A true owner's retreat, a spacious bedroom with a walk-in closet and a full en-suite bath, added where the current house has no room for one. We coordinate the framing, the plumbing for the bath, and the finish work so the new suite feels original to the home.
A light-filled room for morning coffee and Bay-country views. A three-season sunroom extends the shoulder seasons; a fully insulated four-season room with proper heating and cooling lives comfortably year-round. We build both, matched to how you'll actually use the space.
Multi-generational living is common across Southern Maryland, and an in-law suite, a bedroom, bath, sitting area, and sometimes a kitchenette, gives an aging parent or adult child independence under the same roof. We build to the accessibility and code details these suites require.
When the lot won't allow building out, we build up. A second-story addition can nearly double a home's living space without giving up yard, though it's the most involved addition we do, the existing structure has to carry the new load. We assess that carefully before we ever quote it.
A room addition in our area typically runs from about $30,000 to $120,000 or more, depending on size and finish. Four factors move that number most: the foundation (a slab or crawl space costs less than a full basement below the addition), the overall size and how many rooms it includes, how much we have to tie into your existing plumbing, electrical, and HVAC, and the finish level you choose. A modest sunroom sits near the low end; a primary suite or in-law suite with its own bath and kitchenette lands higher. Because additions vary so widely, we price yours only after we see the site and understand the connections, always in writing, with no surprise line items.
When staying put beats moving, an addition is often the smarter money, and it keeps you in the home and community you already know.
An addition is a small house unto itself, so it draws on the full range of products we install. That means framing lumber and engineered beams from trusted suppliers, roofing shingles from GAF and Owens Corning matched to your existing roof, siding from James Hardie and CertainTeed, energy-efficient windows from Andersen and Pella, and interior finishes from the same lines we use throughout the home. Everything is installed to manufacturer spec so the warranties hold and the addition performs like the day it was built.
We build additions throughout Calvert, St. Mary's, and Charles County across Southern Maryland, including Prince Frederick, Solomons, Lusby, Huntingtown, Dunkirk, Owings, St. Leonard, Leonardtown, California, Lexington Park, Hollywood, Waldorf, and La Plata. See our full service area.
An addition touches every trade a house has, and because we handle them all in-house, you're never coordinating a separate framer, roofer, and finish crew. An addition also pairs naturally with the rest of your home, many homeowners fold it into a broader interior remodel so the new and existing space share one design, and a new addition is the natural time to also expand or build a garage. When the addition includes a new kitchen, we bring the same kitchen remodeling team that outfits kitchens across Southern Maryland. One call, one crew, one standard of work from the footing to the final coat of trim paint.
