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.

Chimney repair in Southampton typically costs between $350 and $4,500 depending on whether you need mortar repointing, flashing replacement, or a partial rebuild. Most repairs we perform in Southampton, Sag Harbor, and Hampton Bays are completed in a single visit with no-hassle upfront pricing agreed before we start. You can reach us at (516) 619-2915 - a live person answers, 24 hours a day.
We’ve been repairing chimneys in Southampton since 1984. That’s over 42 years of watching salt air off the Atlantic eat away at mortar joints, of seeing freeze-thaw cycles in North Sea and Water Mill crack crowns that were fine in October, of finding squirrel damage in flues from Jamesport to Bridgehampton. Russell Haines built Hearthstone Chimney Co. on a simple idea: document what’s wrong with photos, explain it in plain English, fix it with materials that last, and stand behind the work in writing. No arguing. No surprises on the bill.
Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like Gelco, Olympia Chimney, and Famco. We don’t send a salesman who commissions up your estimate. We send a sweep who knows the difference between a crown that needs sealing and a crown that needs rebuilding, and we’ll show you the photo evidence either way.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In Southampton, we see accelerated mortar decay in homes within a mile of the salt air, particularly in neighborhoods like North Sea and along Meadow Lane. Our repointing uses color-matched, type-N or type-S mortar suited to your chimney’s age and exposure, applied with proper joint profiles so water sheds instead of pools. Most repointing jobs on a standard chimney run one to two days.
Spalling Brick Repair
Spalling Brick Repair addresses what happens when moisture trapped inside bricks freezes, expands, and pops the face off the brick. It’s common in Southampton after wet winters, especially on chimneys with failed crowns or missing caps. We remove spalled bricks to sound substrate, install matching replacements, and address the water source so it doesn’t repeat. In older homes near Cutchogue and Mattituck, we often source reclaimed brick to maintain visual consistency with historic facades.
Chimney Waterproofing
Waterproofing is a breathable silane/siloxane treatment applied to the exterior masonry that repels liquid water while letting vapor escape. We apply it after any masonry repairs are complete, never as a cover-up for active leaks. A properly waterproofed chimney in Southampton’s coastal climate can add 10 to 15 years of service life. We use professional-grade formulations, not the big-box versions that trap moisture and accelerate damage.
Flashing Repair
Flashing is the metal seam where your chimney penetrates the roof, and it’s the single most common leak point we find in Southampton inspections. We repair or replace step flashing, counterflashing, and cricket saddles using copper or galvanized steel, properly integrated with your roofing material. In homes near Shinnecock Hills with complex rooflines, we often fabricate custom flashing on-site for a watertight fit that factory pieces can’t match.
Chimney Rebuilding
When deterioration exceeds what spot repairs can address, we rebuild. This ranges from partial rebuilds of the top few courses above the roofline to full teardowns when the structure is compromised. Every rebuild in Southampton starts with a level-2 camera inspection to assess the flue condition inside before we touch the brick outside. We match existing brick and mortar profiles, and we document the entire process with photos you can see.
Tuckpointing
Tuckpointing is the decorative and functional technique of removing old mortar and installing new mortar with a thin contrasting line for a crisp, maintained appearance. In Southampton’s historic districts and in classic shingle-style homes from Water Mill to Bridgehampton, proper tuckpointing preserves architectural integrity while sealing out water. We match the original joint style, whether it’s struck, weathered, or flush, using lime-based mortars appropriate to the building’s era.

Brands We Service for Chimney Repair
We work exclusively with professional-grade materials from manufacturers we’ve trusted for decades. For chimney caps and custom shrouds, we regularly specify Gelco products - their stainless steel and copper caps hold up to Southampton’s salt air far better than the galvanized units we replace. We’ve installed hundreds of Gelco caps from Noyack to East Quogue, and we stock common sizes for same-visit replacement when a cap has blown off in a nor’easter.
For liner repairs and relining work, we rely on Olympia Chimney and Famco components. Olympia’s flexible stainless liners are what we use when a Southampton flue has suffered glaze buildup or minor deformation but doesn’t need full replacement. Famco’s venting accessories solve draft problems in tight clearances common in 1970s-era homes throughout Hampton Bays and Flanders. Whether your system was originally built with these brands or any other make, we can source the right parts and install them correctly.
We also work with Copperfield supply components and HeatShield cerfractory resurfacing products for flue restoration. The point is this: we don’t improvise with builder-grade substitutes. The material specification is written on your estimate, and that’s what goes in your chimney.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on exterior brick - This powdery white deposit means water is moving through your masonry, dissolving salts, and depositing them on the surface. It’s not just cosmetic. In Southampton’s freeze-thaw climate, that water is expanding inside your bricks every winter, opening cracks that let more water in. We’ve repointed chimneys in North Sea that went from light efflorescence to spalled brick in three seasons.
- Cracked or missing chimney crown - The crown is the concrete cap that sheds water away from your flue and masonry. A crack as thin as a dime lets water straight into the chimney core. We inspect crowns with binoculars from the ground first, then up close - and we photograph what we find so you can see whether a sealant repair will suffice or if the crown needs rebuilding.
- Rust stains on the chimney face or fireplace surround - Rust means metal is corroding inside your chimney, usually the damper, firebox, or liner. In coastal Southampton, salt accelerates this dramatically. Rust stains on a brick face almost always trace to a failed cap or crown that has been letting rain onto metal components for months or years.
- Damp or musty smell from the fireplace in summer - That odor is moisture in your flue, often from a leak at the flashing or crown. It means water is pooling somewhere it shouldn’t be, and in humid Southampton summers, it’s also a mold risk. A camera inspection locates the entry point without guesswork.
- Loose or crumbling mortar you can flake with a fingernail - Sound mortar should resist scratching. If you can dig it out, water already has. This is especially urgent on the windward side of chimneys in exposed locations like Flanders and Jamesport, where driving rain accelerates deterioration.

How Much Does Chimney Repair Cost in Southampton?
Chimney repair costs in Southampton vary with the scope, access difficulty, and materials required, so here’s how much Chimney Repair costs in typical cases. Here’s what we typically see in local homes:
| Repair Type | Typical Range in Southampton | What Affects Price |
|---|---|---|
| Mortar repointing (standard chimney) | $1,200 - $3,500 | Height, scaffold needs, mortar type match |
| Spalled brick replacement (localized) | $350 - $1,200 | Brick sourcing, extent of water damage behind |
| Chimney waterproofing | $450 - $950 | Surface area, prep cleaning needed |
| Flashing repair or replacement | $650 - $2,200 | Roof pitch, metal type (copper vs. galvanized), cricket needed |
| Partial chimney rebuild (above roofline) | $2,800 - $6,500 | Courses to rebuild, liner condition, cap/crown replacement |
| Full chimney rebuild | $8,500 - $18,000+ | Height, foundation, flue system, historic match requirements |
These ranges reflect Southampton’s market specifically - higher than inland regions due to coastal access challenges, salt-air material specifications, and the prevalence of custom architectural details in homes from Bridgehampton to Water Mill. The best way to avoid overpaying is to get a documented inspection with photos you can see, not a verbal quote from a ladder.
