Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Cleaning in Mamaroneck, NY
Chimney cap and crown work in Mamaroneck usually runs $400-$1,900 depending on whether we’re sealing a crown or replacing a multi-flue cap, while liner and rebuild jobs start around $2,500 and can reach $12,000 for a full rebuild. Homes here, mostly 1920s-1940s brick and stone construction sitting a few blocks from Long Island Sound, absorb salt-laden wind off the water all winter, and that weather pattern creates crown cracking and mortar washout sooner than inland towns see. Call (914) 350-5204 for a written quote before any work starts.
Why Mamaroneck Homes Are Different
Mamaroneck sits directly on Long Island Sound, and that position does two things to chimneys that inland Westchester towns don’t face. First, persistent salt air works into mortar joints and accelerates erosion, especially on the south and southwest faces where prevailing Sound winds hit hardest. Second, the freeze-thaw cycle common here means water that seeps into hairline crown cracks freezes, expands, and pries those cracks wider every winter. The dense stock of 1915-1950 Tudor, Colonial, and center-hall homes compounds the issue: most still carry original clay tile flue liners that are now a century old, cracked, and often unlined by modern standards. Sweeps working Orienta Point and the waterfront blocks routinely find chimneys that look fine from the street but have severe salt-accelerated mortar washout on the weather-facing sides. That failure pattern doesn’t appear the same way even a few miles inland in Scarsdale or Harrison.
Our Main Mamaroneck Services
These are the three service pages most Mamaroneck homeowners land on when they research chimney work here.
Chimney Cleaning & Sweep in Mamaroneck
Annual sweeping in Mamaroneck matters more than in inland towns because coastal humidity mixes with creosote and accelerates glazing inside the flue. We run a camera down the flue on every visit under NFPA 211 Level 2 standards, document what we find, and hand you a written record before we leave. The full scope for sweeps in this area is on our Chimney Cleaning & Sweep in Mamaroneck page, including pricing for wood-burning and gas fireplace systems.
Chimney Repair in Mamaroneck
Spalling brick and cracked crowns are the two most common repair calls we get from Mamaroneck homeowners, and both trace back to Sound-driven moisture intrusion. We address mortar joints, flashing, smoke chamber parging, and crown resurfacing with written pricing before any work starts. See the full breakdown of what we fix and what it costs on the Chimney Repair in Mamaroneck page, which covers masonry, flashing, and structural repairs common to coastal Westchester homes.
Fireplace Services in Mamaroneck
Mamaroneck’s older homes often have fireplaces that were converted from coal to wood or gas decades ago, and those conversions leave behind draft issues, worn dampers, and firebox cracks. We inspect the full firebox, damper assembly, and smoke chamber, then provide a written scope for any gas log set, fireplace repair, or rebuild work. Details on gas and wood-burning fireplace service in this area are on our Fireplace Services in Mamaroneck page.

BeforeAfterChimney Cap & Crown in Mamaroneck
Chimney cap and crown failures are the single most common structural issue we repair in Mamaroneck, because the cap and crown are the two parts of the chimney that take direct hits from Sound-driven wind and salt air. A cracked crown lets water into the masonry below, which freezes and spalls brick faces within a couple of seasons; a missing or rusted cap lets rain, leaves, and sometimes birds straight into the flue. The full scope for this work is covered on our Chimney Cap & Crown page.
Cap Installation
Signs you need it
You can see down into the flue from the roof, or you’ve found birds, nests, or rainwater pooling in the firebox after storms.
What it costs in Mamaroneck
Expect $400-$900 for a standard single-flue cap installed, depending on flue size and roof access.
How we do it
We measure the flue tile, select a stainless steel cap that fits, secure it with mechanical fasteners, and photograph the finished install.
Crown Repair
Signs you need it
Hairline cracks, crumbling mortar at the top of the chimney, or water staining on the ceiling near the flue chase.
What it costs in Mamaroneck
Crown repair and resealing typically runs $500-$1,500 depending on crown size and how much of the top surface needs rebuilding.
How we do it
We grind out loose material, build a proper crown form with a drip edge where needed, apply a waterproof sealant, and record the work photographically.
What Chimney Cap & Crown Costs in Mamaroneck
| Item | Typical range in Mamaroneck |
|---|---|
| Single-flue cap installation | $400-$900 |
| Multi-flue cap installation | $800-$1,900 |
| Crown repair and resealing | $500-$1,500 |
Do I need a new crown or can it be patched?
If the crown has hairline cracks and no spalling, patching with a waterproof sealant usually works. If the surface is crumbling or the drip edge is gone, a full recast is the durable fix. We’ll show you photos either way.
Will a new cap stop my chimney from leaking?
A cap stops rain from entering the flue directly, but leaks around the crown, flashing, or masonry will continue. We inspect all three during the same visit and give you a written scope covering only what needs work. Call (914) 350-5204 for a quote.
Chimney Liner & Rebuild in Mamaroneck
Mamaroneck’s pre-1950 housing stock almost always has original clay tile flue liners, and a century of coastal moisture and temperature swings leaves many of them cracked or separated at the joints. A compromised liner means combustion gases can move into the house, which is a carbon monoxide risk, not a cosmetic issue. See what’s involved on our Chimney Liner & Rebuild page.
Stainless Steel Liner
Signs you need it
Clay liner sections are cracked, spalled, or missing, or the chimney was built without a liner and you’re burning wood or gas.
What it costs in Mamaroneck
Stainless steel liner installation runs $2,500-$5,500 depending on flue height and whether insulation is required.
How we do it
We size the liner to the appliance, insulate if code requires, drop it down the flue, connect at top and bottom, and photograph the entire run.
Partial Rebuild
Signs you need it
The top section of the chimney has spalled bricks, loose mortar, or a leaning stack above the roofline.
What it costs in Mamaroneck
Partial rebuilds in Mamaroneck typically run $2,500-$7,000 based on how many courses need to come down and rebuild access.
How we do it
We remove deteriorated brick course by course, match the masonry as closely as the original allows, rebuild with new mortar, and cap with a new crown.
What Chimney Liner & Rebuild Costs in Mamaroneck
| Item | Typical range in Mamaroneck |
|---|---|
| Stainless steel liner | $2,500-$5,500 |
| Partial rebuild | $2,500-$7,000 |
| Full chimney rebuild | $8,000-$12,000 |
How do I know if my liner is actually cracked?
The only way to know is a camera scan. We run a camera down the flue and show you the footage on site. If the liner is intact, we’ll tell you and you owe nothing beyond the inspection.
Can a partial rebuild fix all my chimney problems?
Only if the damage is confined to the top section. If the liner, smoke chamber, or firebox is also compromised, you’ll need a larger scope. We’ll show you photos of every area before quoting anything. Call (914) 350-5204.

Prices in Mamaroneck run slightly higher than inland Westchester because roof access on older waterfront homes is often tighter and masonry work takes longer when salt exposure requires more material removal. Whatever the number, it’s written down before we start, with a written scope and warranty, and the price doesn’t change after the fact.
