Regrade and waterproof a still-flooding basement areaway at a rowhouse on the 4900 block of Nannie Helen Burroughs Avenue NE, Deanwood, Washington, DC 20019

The drain-clear job at this rowhouse on the 4900 block of Nannie Helen Burroughs Avenue NE, Deanwood, Washington, DC 20019 found the areaway still ponds with a clear drain — the floor itself slopes the wrong way and the wall face is bare masonry soaking up every rain. Regrading the floor and coating the wall stops the seepage at the source. Standard: Intermediate repair of a rowhouse areaway that keeps flooding after drain clearing — regrading the areaway floor to positive drainage and applying a waterproof coating to the below-grade wall face, ground-level work only (no excavation beyond the areaway's existing floor). Proof: before/after photos + slope measurement + water-test + GPS Method (Rowhouse areaway regrade + waterproof coating — intermediate ground-level masonry/drainage repair, no excavation below the existing areaway floor, ~90-180 min): 1. ASSESS: confirm via the prior drain-clear job's finding that the areaway still ponds after a clear drain; photograph the floor slope, wall face and drain location; confirm the areaway walls are sound (no active structural cracking) before regrading. 2. Regrade the areaway floor with sand/gravel fill to a positive slope toward the drain (minimum 1/4 inch per foot), tamping as you go; re-test water flow to the drain. 3. Patch any minor wall cracks with masonry compound, let cure, then apply a waterproof/damp-proofing coating to the below-grade wall face per the product's instructions. 4. Let the coating cure per spec, then photograph the finished areaway (floor slope, coated wall, clear drain) and re-run the water test showing drainage with no ponding. Equipment: masonry patch compound + trowel, waterproof/damp-proofing coating + brush or roller, sand/gravel for regrading the floor slope, camera + level + tape measure Done when: Floor slopes positively to the drain (measured, not just visual); Wall coating fully cured with no missed spots in the after photos; Water test after the work shows no standing water

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

before/after photos + slope measurement + water-test + GPS

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 90–180 minutes. Method of record: Rowhouse areaway regrade + waterproof coating — intermediate ground-level masonry/drainage repair, no excavation below the existing areaway floor

Bring

• masonry patch compound + trowel
• waterproof/damp-proofing coating + brush or roller
• sand/gravel for regrading the floor slope
• camera + level + tape measure

Steps

1. 1. ASSESS: confirm via the prior drain-clear job's finding that the areaway still ponds after a clear drain; photograph the floor slope, wall face and drain location; confirm the areaway walls are sound (no active structural cracking) before regrading.
2. 2. Regrade the areaway floor with sand/gravel fill to a positive slope toward the drain (minimum 1/4 inch per foot), tamping as you go; re-test water flow to the drain.
3. 3. Patch any minor wall cracks with masonry compound, let cure, then apply a waterproof/damp-proofing coating to the below-grade wall face per the product's instructions.
4. 4. Let the coating cure per spec, then photograph the finished areaway (floor slope, coated wall, clear drain) and re-run the water test showing drainage with no ponding.

If it does not match the plan

• A structural wall crack, bulge, or sign of foundation movement -> STOP, do not coat over it; route to a licensed structural/foundation contractor.
• Any excavation below the existing areaway floor level (deeper drain-line repair) is outside this job's scope -> route to a licensed plumber/excavation contractor.

What counts as done

• Floor slopes positively to the drain (measured, not just visual)
• Wall coating fully cured with no missed spots in the after photos
• Water test after the work shows no standing water

Proof is measured against these, not judged by taste.
