Drywall Repair in Montgomery County, MD

One county, three generations of walls

Montgomery County has roughly 408,700 homes, and what sits behind your paint depends mostly on when your house was built. Census survey figures for 2024 put about four in ten county homes in the 1950s, 1960s and 1970s, fewer than one in ten before 1950, and close to a quarter in 2000 or later. That spread is why we ask for a photo and the build year before quoting: a crack in 1920s plaster, a split seam in 1960s gypsum board and a popped screw in a 2015 townhouse each need a different repair.

Housing type matters as well. A little under half of county homes are detached houses, about 18% are townhouses, and roughly a third sit in buildings with two or more units, from garden apartments to high-rise condos near the Red Line. Attached homes share walls and ceilings with neighbors, so a leak or a repair can involve a property manager or homeowners association as well as you.

Our Montgomery County service area: down-county, mid-county and up-county

Down-county: Chevy Chase, Somerset, Kenwood, Bethesda, Silver Spring and Wheaton

The oldest walls in the county are here. Chevy Chase grew out of the Chevy Chase Land Company's streetcar suburb along Connecticut Avenue, begun in 1890, and Somerset's first house went up in 1893; its historic district runs from Queen Anne and bungalows to Colonial Revival. Plaster stayed the standard interior finish until after World War II, so many of these homes still have it. We repair plaster as plaster instead of dropping a square of drywall into it; our guide to plaster vs. drywall in older homes explains why. In Kenwood, Somerset and Kensington, we confirm the wall material before choosing a method.

Silver Spring and Wheaton add a large stock of post-war houses; Wheaton filled in during the 1950s with Cape Cods, ramblers and split-levels. Their early gypsum board and thin-coat walls tend to crack at door corners and ceiling joints as houses move. See drywall repair in Chevy Chase, drywall repair in Bethesda and drywall repair in Silver Spring for neighborhood detail.

Mid-county: Rockville, North Bethesda, Potomac, Gaithersburg and Olney

Mid-county is largely post-war and later. Rockville annexed the Twinbrook subdivision in 1949, adding hundreds of homes at once, while Gaithersburg stayed largely rural until the 1970s and Olney was farmland into the 1960s. Planned communities followed: Montgomery Village, begun by Kettler Brothers in 1966, and the Kentlands in Gaithersburg, started in 1988 as a New Urbanist neighborhood. Typical calls here are ceiling seam cracks, anchor holes left by past owners, chipped corner bead on stairways and water damage under bathrooms. More on drywall repair in Rockville, plus our Gaithersburg, North Bethesda, Potomac and Olney pages.

Potomac

Potomac homes run bigger than most of the county, and so do the walls. Many houses from the 1980s and 1990s, in Avenel, around Potomac Village and off River Road, have two-story foyers, great-room ceilings and open stairwells where a crack or a dented corner sits well beyond the reach of a step ladder. Those repairs need a tall extension ladder or a rolling scaffold set up indoors, with floors and stair treads protected, so tell us the ceiling height when you text your photos. Drywall of that era often cracks along the metal corner bead at stair and archway corners and along ceiling seams over long spans. We cut out failed bead, set new bead, and rebuild the corner in thin coats before priming and painting. For everything else we do there, see our handyman in Potomac page.

Gaithersburg and Clarksburg

Newer neighborhoods in Gaithersburg, such as the Kentlands and Lakelands, and much of Clarksburg were framed with lumber that keeps drying through its first few heating seasons. As it shrinks, fastener heads push through the finish as round bumps, and hairline settlement cracks open over doorways, along stairwell seams and where walls meet ceilings. If your home is still under a builder warranty, check that first; after that, we reset the pops and tape the cracks instead of caulking them, so they stay closed.

Olney and Kensington

Olney grew out of farmland from the 1960s on, so most calls there are seam cracks, nail pops and patches after plumbing work in ranchers, colonials and townhouses. Kensington's Victorian and early-1900s houses near the historic district are the opposite: plaster on wood lath, which we repair as plaster; see plaster wall and ceiling repair for how.

Up-county: Germantown, Clarksburg and beyond

Up-county has the county's newest homes. Clarksburg was planned for townhouse and single-family neighborhoods under master plans adopted in 1968 and 1994, and much of it, like much of Germantown, has gone up in the last few decades. New construction brings its own wall problems: fastener pops as framing dries, hairline cracks over doorways and along seams, and cracked corner bead. Much of the rest of up-county lies in the 93,000-acre Agricultural Reserve created in 1980, so homes are farther apart; send your address with your photos and we'll confirm a window. See our Clarksburg and Laytonsville pages.

Nail pops in newer homes

A nail pop is a fastener working loose from the framing behind it. Seasonal humidity swings make it worse: wood swells in a humid Maryland summer and shrinks again once the heat comes on. Pushing the old nail back in rarely lasts. We drive a drywall screw an inch or two away to pull the board tight to the stud, set or remove the old nail, then spot the area with compound, sand, prime and paint. Our guide to why nail pops keep coming back covers the causes in more detail.
