Short answer
Alexandria homeowners can get a repair estimate from Runhome in minutes by sending a description or photos, priced from real contractor data. From there, Runhome contacts contractors in Northern Virginia, gathers their quotes and sets a visit time. Only about 14% of Alexandria homes are single-family detached, so many repairs involve shared walls in rowhouses, townhomes and condos.

What Alexandria’s housing means for repairs
Alexandria's housing is dense and varied. Only about 14% of homes are single-family detached, the lowest share in this group, and 42% are owner-occupied. The rest are rowhouses, townhomes, condos and apartments. The median home was built in 1974, about 29% predate 1960 and about 22% went up in 2000 or later, much of it around Potomac Yard and Carlyle.
Old Town holds rowhouses from the 18th and 19th centuries, with brick walls, wood floors, plaster and old plumbing that has been updated piece by piece. Exterior changes there generally go through the city's historic review process. Del Ray and Rosemont have early 20th-century bungalows and foursquares with basements. Gas and electric heat are close to even (about 47% and 50%), so you see both furnaces and heat pumps.
Weather that wears on Alexandria homes
Alexandria has hot, humid summers and cold winters with freeze-thaw cycles that crack brick, mortar and front steps. Low-lying parts of Old Town near the Potomac waterfront flood during high tides and storm surge, and heavy summer thunderstorms have overwhelmed storm drains and flooded basements in neighborhoods like Del Ray. Humidity keeps basements damp and helps mold grow after leaks. Nor'easters and the remnants of tropical storms bring wind-driven rain that finds gaps in old windows and flashing. Snow is moderate, but ice dams form on older roofs. Large street trees drop limbs and fill gutters each fall.
Common repairs in Alexandria
Basement waterproofing
Heavy storms and a high water table near the river push water into basements.
Bathroom leak through the ceiling
In multi-story rowhouses, a failed tub or shower seal often shows up on the ceiling below.
Brick and mortar repair
Freeze-thaw cycles and age loosen mortar on brick rowhouses and steps.
Heat pump and furnace service
Alexandria splits between gas and electric heat, and both run hard in humid summers and cold winters.
Old window repair
Older wood windows stick, leak air and let in wind-driven rain.

Fix guides for Alexandria homeowners

In Alexandria's multi-story rowhouses, bathroom leaks show up as stained ceilings on the floor below.

Sewage backs up into the basement floor drain
Heavy storms can overwhelm sewers and back up basement drains in Alexandria.
Seasonal checklist
- Spring
- Clear downspouts and check that basement drains and sump pumps work before storm season.
- Summer
- Run a basement dehumidifier and watch ceilings below bathrooms for new stains.
- Fall
- Clean gutters after the leaves drop and service your furnace or heat pump.
- Winter
- Check brick steps and walls for loose mortar after hard freezes.
Common questions
- Do I need approval before exterior repairs in Old Town Alexandria?
Exterior changes to homes in Alexandria's historic districts generally go through the city's Board of Architectural Review, which can affect materials such as windows, doors and siding. Like-for-like repairs may be simpler than replacements. Check with the city before work starts, since approvals add time and can affect what materials a contractor quotes.
- Why is water coming through my Alexandria ceiling after a shower?
In rowhouses and townhomes, bathrooms often sit right above living areas. A cracked grout line, failed caulk or worn shower valve lets water into the floor and it shows up on the ceiling below. A plumber finds the source first, then the ceiling gets dried and repaired.
- How do I keep my Alexandria basement dry during summer storms?
Extend downspouts away from the house, keep window wells clear and make sure your sump pump works. Older homes may need a backwater valve to stop sewer water from backing up. The cost of waterproofing depends on whether the fix is outside grading, interior drainage or a combination.
