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.

AfterFast, Reliable Chimney Repair Across Old Greenwich
Chimney repair in Old Greenwich generally runs $425-$1,850 for the most common jobs: flashing replacement, mortar repointing, and crown resealing. That range covers the repair work most sound-side homes need after a nor’easter season. Full chimney rebuilding starts around $6,500 for a single-flue stack and $12,000+ for the multi-flue Victorian stacks common along Shore Road. Call (516) 399-5497 for a written, line-item quote before any work is scheduled - that’s how we’ve quoted every job since 2009.
Our crews know Old Greenwich block by block. The salt air off Long Island Sound shortens the life of chimney caps, flashing, and mortar joints on Shore Road, Sound Beach Avenue, and the side streets running down to Binney Park - Chimney Repair here isn’t a seasonal afterthought. It’s recurring maintenance on masonry that faces conditions inland Fairfield County homes never see.
Why Level Two Chimney Greenwich Is Old Greenwich’s Preferred Chimney Repair Company
We’ve inspected and repaired chimneys across Old Greenwich for years, from the colonials on Forest Avenue up to the shingle-styles near Greenwich Point, and two things show up on our work orders more than anything else: salt-corroded flashing and spalled upper brick courses. Corrine Halstead leads our Greenwich operations, and every repair quote she signs follows the same standard: camera-scan inspection first, written price second, photo record before we leave.
That last part isn’t optional for us. Clause 4 of the Haven Standard requires a documented photo record on every repair job, and we’ve worked that way since 2009 - you see exactly what we saw inside the flue, on the crown, and behind the flashing. No other chimney company in Old Greenwich shows customers their own chimney on camera before asking for a signature. We do it on every visit, repair or inspection.
Every technician sent to an Old Greenwich address is background-checked and uniformed. You’ll get a text when your crew is en route, and your written scope includes the material brands before we touch a single brick. Chimney Repair in Old Greenwich has to account for coastal corrosion cycles, and our repair recommendations reflect that local reality rather than a generic checklist.
Our Chimney Repair Services in Old Greenwich
Key takeaways:
- Flashing repair in Old Greenwich runs $425-$850 for standard step flashing replacement.
- Mortar repointing on a sound-side chimney averages $850-$2,200 depending on upper-course access.
- Chimney waterproofing with a vapor-permeable sealant runs $550-$1,400 per chimney.
- Post-nor’easter inspection calls spike every March and April along Shore Road and Sound Beach Avenue.
Mortar Repointing in Old Greenwich
Salt-laden nor’easter winds push moisture into exposed mortar joints on chimneys facing Long Island Sound. Old Greenwich homes within a few blocks of the water - Shore Road, Sound Beach Avenue, and the streets off Laddins Rock Road - show joint erosion years ahead of inland chimneys. Repointing means cutting out the deteriorated mortar to a proper depth and packing in fresh mortar matched to the original’s strength and texture. For Old Greenwich chimneys, we typically use Type N mortar with a slight polymer additive for salt resistance.
Repointing on a standard single-flue chimney in Old Greenwich runs $850-$1,800. A multi-flue Victorian stack with heavy upper-course erosion runs $1,600-$3,200. The price difference is almost always access and square footage of the affected masonry - we’ll show you photos of every joint we plan to cut before we quote it.
Spalling Brick Repair in Old Greenwich
Spalling is the flaking or popping of brick faces caused by absorbed moisture freezing and expanding. On Old Greenwich chimneys within the salt-spray zone, spalling usually appears on the upper three to five courses first - that’s where nor’easter winds drive the most water into the brick. We see this on Shore Road Victorians where the chimney crowns were built without proper overhang, leaving the top courses permanently damp from October through April.
Individual brick replacement in Old Greenwich runs $85-$165 per brick including mortar work and color matching. If spalling affects more than a quarter of the upper stack, partial rebuilding is the better route. We’ll tell you plainly when patching will hold and when it won’t - the photos make the case either way.
Chimney Waterproofing in Old Greenwich
Waterproofing matters more here than anywhere else in Fairfield County’s inland towns. The persistent salt air off the Sound, combined with Connecticut’s hard freeze-thaw cycles from October through April, means untreated masonry absorbs moisture continuously. We apply a vapor-permeable silane-siloxane sealant that blocks liquid water while letting the brick breathe. This is the single most cost-effective preventive measure for Old Greenwich chimneys under five blocks from the water.
Waterproofing runs $550-$1,400 per chimney depending on height and masonry condition. The sealant bonds properly only after any necessary repointing and crown repair - waterproofing over crumbling joints is waste. We sequence the work correctly and document each stage with photos.
Flashing Repair in Old Greenwich
Flashing is the sheet metal where the chimney meets the roofline, and on sound-side Old Greenwich homes it fails faster than anywhere else in town. Salt corrosion eats through galvanized flashing in five to seven years. We replace it with stainless steel or copper, fabricated on-site for the chimney’s exact dimensions. Shore Road and the streets running down to Binney Park see flashing failures every spring after the nor’easter season.
Step flashing replacement in Old Greenwich runs $425-$850. Full counter-flashing with new base flashing and soldered corners runs $750-$1,250. We use Famco and Copperfield flashing components because they hold up under coastal conditions better than big-box galvanized stock.

BeforeAfterTrusted Brands We Service in Old Greenwich
We stock repair materials from HeatShield, DuraFlex, and Copperfield for Old Greenwich jobs, and we can usually have specialized parts in hand within two to three business days when a chimney needs something unusual - a specific crown form, a stainless cap for an odd flue dimension, or a HeatShield resurfacing kit for a compromised clay tile liner. We don’t make our customers wait on mail-order parts. We keep the common Old Greenwich repair inventory in our trucks: stainless caps, step flashing stock, crown sealant, and mortar color-matched to the warm red brick common on pre-war colonials along the Sound.
Common Chimney Repair Problems We See in Old Greenwich Homes
- Salt-corroded caps and dampers. Within five years of installation, standard galvanized chimney caps near the Sound show rust-through, and damper assemblies seize from salt accumulation. We routinely replace failed caps with stainless steel and treat damper assemblies with corrosion-resistant hardware. Homes on Shore Road and the streets off Laddins Rock Road are the worst affected.
- Third-degree creosote glaze in seldom-used fireplaces. Large Old Greenwich colonials often have one or two fireplaces that never get burned. The cool flue temperatures allow creosote to condense, harden, and form a glass-like glaze that routine brushing can’t remove. Chemical treatment and camera-scan verification of the flue liner are required before the fireplace is safe to use.
- Upper-course spalling from salt-laden wind. The top three to five courses of masonry absorb wind-driven salt moisture all winter. When the water freezes, brick faces pop. Left unaddressed, upper-course spalling progresses downward until a partial rebuild is necessary - which costs six to ten times what early repointing and waterproofing would have.
- Original multi-flue clay tile liners at the end of their service life. The 1890s-to-1940s colonials along Shore Road and Sound Beach Avenue still have their original clay tile liners in many cases. After 80 to 130 years of thermal cycling and salt exposure, those tiles crack and spall from the inside out. A camera scan tells us whether the liner can be resurfaced with HeatShield or needs full replacement with DuraFlex stainless steel.

FAQs - Chimney Repair in Old Greenwich
Sound-side Old Greenwich chimneys need a Level 2 inspection every year, ideally in early fall before the burning season starts. Homes within three to five blocks of the water on Shore Road, Sound Beach Avenue, and the streets off Laddins Rock Road face salt-laden wind exposure that accelerates flashing corrosion, cap failure, and upper-course spalling - damage patterns that inland Greenwich chimneys see at roughly half the rate. If you burn wood through the winter, that annual inspection also documents creosote buildup before it becomes a fire hazard. Call (516) 399-5497 to book an inspection - the camera scan and photo report are included on every visit.
Original clay tile liners in Old Greenwich Victorians are 80 to 130 years old and have been exposed to salt-laden moisture for all of those years, so they crack and spall from the inside far earlier than liners in inland Connecticut homes. When you repair a multi-flue Victorian chimney, the liner is the part you can’t see from the ground - and if it’s compromised, repointing or crown work won’t make the chimney safe to burn. We camera-scan every flue before recommending repair scope. If the liner is shot, we can resurface it with HeatShield or replace it with DuraFlex stainless steel - and you’ll see the footage that justifies either path.
No. A gas insert installation in an Old Greenwich masonry fireplace requires a structurally sound chimney with intact upper courses, a functional liner, and a crown that sheds water properly. If salt damage has spalled the upper brick or corroded the flashing, those conditions must be corrected before the insert venting can be safely connected. Installing an insert into a compromised chimney creates a carbon monoxide risk. We don’t do it, and any reputable installer in Old Greenwich will tell you the same. We repair the masonry first, then coordinate with your insert installer on vent sizing.
Repointing is structural - cutting out deteriorated mortar and replacing it with fresh, properly matched mortar to restore the joint’s water resistance and structural integrity. Tuckpointing is cosmetic - a thin contrasting line of lime putty applied over fresh mortar to create the illusion of fine, uniform joints in older brickwork. For Old Greenwich chimney repair, repointing is the work that matters. Tuckpointing on a chimney is rarely worth paying for unless you’re restoring an architectural feature on a landmark-quality home. If your mortar joints are eroded, repointing fixes the problem; tuckpointing just dresses it up. We’ll tell you which one your chimney needs, with photos.
Yes. Crowns on sound-side Old Greenwich chimneys need a flexible, breathable sealant designed for constant salt exposure and hard freeze-thaw cycling - a standard crown coat fails in two to three seasons near the water. We use a silane-siloxane crown sealant with elastic properties so it stretches with thermal expansion instead of cracking. The crown is the most water-vulnerable surface on any chimney, and on Shore Road and Sound Beach Avenue it takes a beating. Crown sealing runs $350-$700 depending on size and condition, and it should be done before or alongside waterproofing the masonry below it. Call (516) 399-5497 and we’ll camera the crown from above so you can see its condition before we quote.
