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.
Fast, Reliable Chimney Repair Across Old Greenwich
Chimney repair in Old Greenwich, CT is a shoreline-specific job. Most calls we take here are for cracked crowns and failed flashing, not draft problems. Salt-laden air off Long Island Sound and hard freeze-thaw cycles work on masonry chimneys year after year, and by the time a homeowner sees a rust streak or damp spot, water has usually been tracking down the flue liner for months. We serve the whole Old Greenwich area, from Sound Beach Avenue down to Shore Road, with written pricing before any work starts. If you need a straight answer about a chimney, call (830) 251-4560.

Chimney Flashing Repair in Old Greenwich
Chimney Flashing Repair in Old Greenwich is the most common repair we perform in this shoreline market, and it almost always comes down to one thing: copper or aluminum flashing that has pulled away from the masonry after years of coastal wind and freeze-thaw movement. Flashing is the metal barrier where the chimney meets the roofline. When it fails, rainwater and snowmelt run straight down the outside of the chimney and into the attic. In Old Greenwich, a typical flashing repair runs $450 to $900, depending on whether we’re replacing a single side, re-securing the step flashing, or pulling and replacing the full apron and counter-flashing. Hank Delano says every Old Greenwich flashing quote starts with a roof-level inspection and photos so you can see the separation before approving any work.
What a Coastal Flashing Failure Looks Like
On homes along Shore Road and Sound Beach Avenue, we see the same pattern over and over. The windward side of the flashing loosens first, usually at the corner seams. Water seeps into the brick, the mortar behind the flashing starts to soften, and within a season or two you get a dark stain on the ceiling near the fireplace or a musty smell in the attic. This is not a maintenance item you can defer indefinitely. Once the flashing is open, every rain event is pulling moisture deeper into the chimney chase and the framing around it.
Repair vs. Replacement
Some Old Greenwich flashing failures can be repaired with fresh sealant and re-secured fasteners, and we’ll tell you when that’s a legitimate fix. But most shoreline flashing we see is original to the house, and original flashing has cycled through decades of salt air. In those cases, we replace it with new copper flashing. Copper handles the coastal environment better than aluminum, and we specify it by job, not by margin. On a 1920s colonial off Shore Road, we recently rebuilt a cracked crown and reflashed the chimney base with Copperfield copper after a Level 2 inspection showed meltwater entering the smoke chamber. The moisture reading dropped to dry on the follow-up visit.
Chimney Crown Repair in Old Greenwich
Chimney Crown Repair in Old Greenwich is the first fix on most jobs here, not a follow-up to sweeping. The crown is the concrete or mortar cap at the very top of the chimney, and in Old Greenwich it takes the worst of the coastal weather: salt spray, driving rain, and freeze-thaw cycles that crack the surface every January. A standard crown repair in Old Greenwich typically runs $600 to $1,200. If the crown has failed completely and water has reached the flue liner, the cost climbs because we have to address the liner too. Every crown job starts with a visual from the roof and a camera inspection up the flue, so you see exactly what we see.
Why Shoreline Crowns Fail Early
The crowns on pre-war Old Greenwich chimneys were often poured with mortar rather than cast concrete, and mortar crowns crack under freeze-thaw stress far sooner. Add salt air that accelerates surface spalling, and a crown that might last 30 years in inland Greenwich can fail in 12 to 15 years here. We see crowns on Sound Beach Avenue homes that look fine from the ground but have a network of hairline cracks that let meltwater into the smoke chamber every winter.
What Crown Repair Involves
When we repair a crown in Old Greenwich, we don’t just patch the cracks. The failed crown is removed, the top course of brick is cleaned and prepped, and a new crown is poured with a proper slope to shed water away from the flue. We build in a drip edge so water falls away from the brick face instead of running down it. On chimneys that have already taken on water, we combine the crown repair with a HeatShield liner application or a clay tile replacement, depending on what the camera shows. The crown stops further water entry. The liner addresses what the water already did.
Trusted Brands We Service in Old Greenwich
We work with professional-grade chimney materials and install the same lines we’d put on our own homes: HeatShield cerfractory liner systems, Gelco waterproofing and crown sealants, Olympia Chimney caps and dampers, and Famco flashing components. Because we stock common Old Greenwich parts locally and coordinate dispatch out of the Garrison Partners Hartford office, most repair jobs in Old Greenwich are quoted, approved, and scheduled in one phone call. You’ll know the material brand before we buy it. You’ll see it on the written scope. No mystery parts, no margin-driven substitutions.
Common Chimney Repair Problems We See in Old Greenwich Homes
- Salt-cracked chimney crowns. Sound air carries salt that works into the crown surface, and freeze-thaw cycles do the rest. Old Greenwich crowns on pre-war masonry chimneys start failing years before inland chimneys of the same age.
- Flashing separation at the roofline. Coastal wind off Long Island Sound flexes flashing seams, especially on the windward side. Once water gets behind the flashing, it runs down the outside of the flue and into the attic or the smoke chamber.
- Spalled clay tile flue liners. Old Greenwich’s pre-war chimneys are lined with original clay tile. When moisture and first-degree creosote sit against that tile all winter, the interior surface flakes away. The camera shows it clearly, and it’s why we recommend a Level 2 inspection on any local chimney over 40 years old.
- Water damage before draft problems. The most common Old Greenwich failure mode we see is water, not smoke. Rain drives past a loose cap into the smoke chamber, collects in the damper area, and rusts the damper hardware long before the homeowner notices any drafting issue.

FAQs About Chimney Repair in Old Greenwich
Yes, and the reason is specific to Old Greenwich’s position low on Long Island Sound. Winter air moving off the water carries salt and persistent damp, and that combination accelerates crown cracking and flashing corrosion on chimney masonry. Add freeze-thaw cycles, and the parts of a chimney that shed water fail years earlier than they do just a few miles inland in Greenwich. Most Old Greenwich repair calls we take start with the crown or the flashing, not the flue. Call (830) 251-4560 if you want a camera inspection of either.
The most reliable way is a Level 2 inspection with a camera run up the flue. But there are earlier signals: a rust streak down the firebox wall, a damp smell in the attic near the chimney, or a thin white mineral deposit on the exterior brick face. All three are common in Old Greenwich and point to crown or flashing failure before the liner is damaged. Our techs document everything with a photo report so you see the evidence yourself. If the camera shows the liner is dry, we’ll tell you it can wait.
We give a flat price before any repair begins, but the number comes after we inspect, not before. That’s the honest sequence. Without seeing the crown, the flashing, and the flue liner, a phone quote is a guess. We come out, inspect with a camera, and hand you a written quote with the scope, the materials, and the exact price. You approve that number before work starts, and the invoice matches it. If a covered repair fails within one year, we return at no charge.
That glaze is third-degree creosote, a hard, tar-like substance that forms when first-degree creosote is heated and cooled repeatedly. A standard chimney brush will not remove it. It requires mechanical removal with rotary chains, and in some cases chemical treatment. In Old Greenwich, where damp winter air accelerates creosote hardening, we often find third-degree creosote in chimneys that haven’t been swept in more than two years. If you have that glaze, book a sweep first. Then we can inspect the liner underneath. Call (830) 251-4560 and we’ll schedule it.
Once a year, per the NFPA 211 standard, and in Old Greenwich that annual check matters more than it does inland. Our shoreline-specific inspection focuses on the parts that fail here first: the crown, the flashing, and the top of the flue liner where salt air and freeze-thaw damage show up earliest. If you burn wood regularly, an annual sweeping plus inspection is the right rhythm. If you only burn a few fires a year, you can usually go 18 months between inspections, but don’t skip the crown check after a hard winter. The camera will confirm what needs work and what can wait.
