About Chimney Waterproofing
Brick is a sponge, and DMV winters are merciless to a wet one. Brickline applies vapor-permeable siloxane sealant that blocks liquid water from entering while letting trapped moisture escape — never paint, never film-forming sealers that suffocate historic brick. Applied after any needed repointing, so you're not sealing over a problem.
Price: $300–$900 · Duration: 2–4 hours
Signs You Need Waterproofing
- White staining (efflorescence) on the brick
- Damp patches on interior walls near the chimney
- Spalling brick faces after winter
- Moss or algae growth on the stack
Why Vapor-Permeable Matters
Film-forming sealers trap moisture inside the brick, where winter freeze-thaw pops the faces off — the exact damage you were trying to prevent. Breathable siloxane blocks incoming rain but lets internal moisture vapor escape. On soft pre-war brick this distinction is everything.

Reviews
What the Neighbors Say
“They matched the mortar on our 1918 rowhouse perfectly. You can't tell where the repair starts. Flat quote, no surprises, brick dust swept off the sidewalk when they left.”
Laura B.
Capitol Hill, DC
“Two other companies told us to tear the chimney down. Brickline rebuilt the top four courses with reclaimed brick and it looks original. Historic review board approved it without a note.”
James O.
Old Town Alexandria, VA
“Sweep and Level 2 inspection before we bought the house. The photo report caught a cracked flue tile the general inspector missed. Worth every dollar of the $250.”
Priya N.
Bethesda, MD
“The $189 sweep is actually $189. Drop cloths everywhere, HEPA vacuum running the whole time, written report with photos before they left. Booking again next fall.”
Marcus T.
Petworth, DC
“Water had been getting into the firebox for two winters. They found the cracked crown in one visit, quoted it flat, and fixed it in an afternoon. Dry ever since.”
Ellen W.
Silver Spring, MD
“No upsells, no scare tactics. The mason who quoted the repointing was the one on the roof doing it. That alone puts them ahead of everyone else we called.”
