A fireplace that smokes, a ceiling stain beside the chimney after a nor'easter, mortar washing out of the joints. Hard winters and salt air are rough on brick. Call our Victory Boulevard shop and we'll send someone out to look at it.

From the firebox to the cap, we clean, inspect and repair every part of the chimney on wood-burning fireplaces, gas inserts and boiler flues.
Creosote & sootCreosote builds up inside the flue every time you burn. We brush it out top to bottom and vacuum the firebox clean.
Annual checkA look at the firebox, damper, flue, crown and exterior brick. Good before the heating season, after a chimney fire, or when buying a home.
Crown · brick · rebuildLoose top courses, cracked crowns and leaning stacks. We repair what can be saved and rebuild above the roofline when it can't.
Where roof meets brickMost chimney leaks start where the roof meets the brick. We reseal or replace failed flashing so wind-driven rain stays outside.
Keep out rain & animalsA cap with a screen keeps out rain, raccoons, birds and squirrels. We fit caps, top-sealing dampers and new crowns.
Oil-to-gas conversionsSwitching your boiler from oil to gas, or have a cracked clay flue? A properly sized stainless steel liner vents exhaust safely.
Water soaks into brick and mortar, freezes, expands and pops the faces off bricks. Each winter makes cracks wider.
Sideways rain finds every gap in flashing and crowns, and shows up as stains on ceilings and walls.
Homes near Midland Beach, South Beach and Great Kills see faster mortar erosion and rusting caps.
Gas exhaust is wetter and more acidic. In an unlined or old clay flue it can eat away at the mortar from the inside.
The same crew that fixes chimneys handles the rest of your brick and block. We match mortar color and brick as closely as possible so repairs blend in.
Crumbling mortar is ground out and replaced with fresh joints, tooled to match the rest of the wall.
Cracked, flaking and missing bricks are cut out and replaced on walls, chimneys and garden features.
Loose treads, cracked risers and crumbling stoops rebuilt so they're safe to walk on again.
Leaning or bulging block and brick walls repaired or rebuilt, common on the island's sloped lots.

The national fire safety standard, NFPA 211, recommends having chimneys, fireplaces and vents inspected at least once a year. Sweeping is done when the inspection finds creosote or debris building up, which for regular wood burners is usually every year.
The usual causes are worn or loose flashing where the chimney meets the roof, a cracked crown, a missing cap, or porous brick and mortar soaking up rain. We trace the source before repairing so the fix actually stops the leak.
Often, yes. Gas appliances produce cooler, wetter exhaust that can damage an unlined or deteriorated clay flue. A stainless steel liner sized for the new appliance helps it vent properly. We inspect the flue and tell you what your setup needs.
Tuckpointing, also called repointing, means grinding out old, crumbling mortar and replacing it with new mortar. If you can scrape mortar out with a key, see gaps between bricks, or notice sand at the base of a wall, it's time.
That's called spalling. Water gets into the brick, freezes in winter and pushes the surface off. Damaged bricks should be replaced and the water source fixed, or it keeps spreading.
Yes. We repair and rebuild brick and block stoops, steps and porches, from loose treads and cracked risers to full rebuilds.
