Masonry Contractor
Licensed Masonry Contractor Serving All Four Boroughs
New York is a masonry city. Brick, brownstone, limestone and block hold up most of the buildings in the Bronx, Brooklyn, Queens and Manhattan, and when the mortar in those walls fails, water follows it straight into the interior. Alliance General Contracting NY Inc restores and rebuilds masonry with matched mortar, matched brick and the flashing details that keep the repair from failing again in three winters.
Mortar is supposed to be softer than the masonry it holds. A great deal of the damage we repair was caused by a previous contractor using a hard Portland-heavy mix on soft historic brick, which forces moisture and movement into the brick face and spalls it. We match mortar type, color and joint profile to the original wall, which matters both structurally and for anything within a landmarked district.
Every masonry contractor project starts with a free on-site estimate and a written scope. We are based at 2362 Westchester Ave, Bronx, NY 10462 close enough to the whole Bronx to respond quickly, and working daily in Brooklyn, Queens and Manhattan. Call 718-737-2143 or email info@alliancegeneralcontractingny.com to get on the schedule.

Common Questions
Frequently Asked Questions
Look for recessed, sandy or crumbling joints, mortar dust at the base of the wall, or damp patches inside along exterior walls. A free inspection will confirm depth of deterioration.
In most cases yes. We source reclaimed and color-matched brick and tint mortar to blend repairs into the surrounding wall.
Small pointing and patching generally does not, but facade work involving scaffolding or structural elements often does. We advise on filing before we start.
