Chimney Cap Install for DC, Maryland & Virginia
An open flue is an invitation — to rain, squirrels, raccoons, birds, and every leaf on the block. A properly fitted stainless or copper cap with mesh screening is the cheapest insurance a chimney can have. Brickline measures, supplies, and installs caps that fit right and stay put through DMV storm seasons.

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.”
