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 Greenwich
Chimney repair in Greenwich, CT typically runs $350 – $950 for crown repair, $850 – $2,400 for flashing replacement, and $1,200 – $3,800 for repointing, depending on access and material condition. We’re Flint Chimney Sweep, part of the Garrison Partners family founded in 2002, and we’ve rebuilt, repointed, waterproofed, and reflashed chimneys from Cos Cob to backcountry Greenwich. Our crews work across the town’s split housing stock, pre-war masonry in Riverside and Old Greenwich, post-1980 factory-built units in the backcountry, and we know which system you have before we ever give you a number. Call (830) 251-4560 and a live person answers, any hour, any day.
Why Flint Chimney Sweep Is Greenwich’s Preferred Chimney Repair Company
Greenwich homeowners call us after a chimney company no-shows, moves the price at the door, or leaves a tarp in the yard and a voicemail nobody returns. We run The Garrison Code: a written price before work starts, a uniformed background-checked technician on the call, and a 365-Day Done Right Promise on every repair we perform. If a covered repair fails within one full year, we return at no charge. No argument, no callback form.
Our repair crews understand Greenwich’s two chimney realities. The pre-war masonry flues along the Post Road corridor and down into Riverside and Old Greenwich. And the factory-built systems scattered through backcountry estates off North Street and Round Hill Road. That dual familiarilty means we don’t show up and guess. We identify the system, scope the work, and quote it in writing. Reviews from Greenwich customers consistently mention the same two things: the written price matched the invoice, and the technician left the work area as clean as he found it.
Dispatch and scheduling are coordinated from our Hartford office; the crews serving Greenwich are local, familiar with the town’s permitting quirks and its older housing stock. When you book, you get a window, a name, and a photo of the technician before anyone arrives. No mystery vans. No “the guy will be there sometime Tuesday.”
Chimney Crown Repair in Greenwich
Chimney Crown Repair in Greenwich means addressing the concrete or mortar cap at the top of your chimney, the flat surface that sheds water away from the flue. In Greenwich’s coastal climate, wind-driven rain and winter freeze-thaw cycles crack crowns faster than they do a few miles inland. A cracked crown lets water into the chimney’s bones, and that water freezes, expands, and slowly spalls the brick and erodes the mortar joints below. By the time a homeowner sees staining on the ceiling or a damp smell near the hearth, the crown usually cracked years earlier.
A crown repair in Greenwich typically runs $350 – $950, depending on whether we’re sealing hairline cracks with a professional-grade elastomeric coating like Gelco or rebuilding the crown entirely with a proper overhang and drip edge. The cheaper fix buys time. The rebuild buys decades, when it’s done correctly.
Signs a Greenwich Homeowner Needs Crown Repair
Hairline cracks running across the crown surface are the earliest warning. Look for spalling, small chunks of concrete or mortar flaking off and landing on the roof or in the gutter. A crown that has pulled away from the flue liner lets water run directly down the outside of the flue, which is a slower, more insidious path into the smoke chamber and firebox. If you see efflorescence, a white chalky deposit on the brick below the crown, water is moving through the masonry.
What the Crown Repair Job Involves
We inspect the crown, document the damage with camera photos, and give you a written price before any work starts. For hairline cracks, we clean, prep, and apply the sealant in weather conditions that allow proper curing. For a rebuild, we form and pour a new crown with a proper slope, an overhang beyond the brick edge, and a drip edge cut into the underside so water sheds away from the chimney. A full rebuild usually takes one day on site.
Chimney Repair Companies in Greenwich
Chimney Repair Companies in Greenwich fall into two groups. The general contractors who add chimney work as a side line, and the specialized shops that inspect, sweep, and repair chimneys every working day. We’re the second kind. Flint Chimney Sweep was born in this trade, we’ve been doing it since 2002 under the Garrison Partners banner, and every repair we perform carries a written one-year guarantee, backed by a free return visit if the covered repair fails within that period.
What actually sets repair companies apart in Greenwich isn’t the truck or the logo. It’s whether the technician carries a camera inspection unit and hands you photographic evidence of the problem before he quotes a fix. We do that on every repair call. You see what we see. If we recommend a repointing job or a crown rebuild, we hand you photos that show exactly why. If work can safely wait, we tell you that plainly and give you a written note on what to watch for.
What Greenwich Homeowners Should Ask Before Booking
Ask whether the price is written before work begins. Ours is, every time, no exceptions. Ask whether the repair carries a written guarantee. Ours does, for one full year. Ask whether the technician is background-checked and in uniform. Ours are. The Garrison Standard isn’t a slogan, it’s the operating code we run every call on.
Why We Inspect Before We Quote
On a recent Midcountry Greenwich property, our tech pulled a Level 2 inspection on a 1920s masonry chimney and found a hairline crack running through the chimney crown with water staining down into the smoke chamber. We rebuilt the crown, renewed the flashing at the roofline, and reinstalled a stainless chimney cap, then sent the homeowner a full photo report before any invoice went out. No surprises. No vague promises. Just a documented job.
Trusted Brands We Service in Greenwich
We specify materials by the job, not by the margin. For flue relining in Greenwich’s pre-war masonry chimneys, we work with HeatShield’s cerfractory sealant system, a cast-in-place product that restores damaged clay flue liners without the cost of full liner replacement. For crown sealing and waterproofing on the town’s coastal-exposed chimneys, we use Gelco’s elastomeric breathable products, which handle Greenwich’s damp winters far better than a hardware-store bucket of masonry sealer. For factory-built systems in newer backcountry homes, we source components through Olympia Chimney and Famco, so the cap or liner matches the original manufacturer’s specification instead of some generic part that never fits right. Because our crews live in and around Greenwich, we keep common parts and materials close by, which shortens turnaround on standard repair work.
Common Chimney Repair Problems We See in Greenwich Homes
- Spalled brick on pre-war masonry chimneys. The freeze-thaw cycles along Long Island Sound’s edge push water into brick faces all winter, and come spring the brick face pops off. We repoint and replace spalled units before the damage reaches the flue liner.
- Flashing failures mistaken for roof leaks. Wind-driven rain off the Sound hammers chimney flashing at the roofline. Homeowners call a roofer, the roofer replaces shingles, and the leak returns. The flashing was the problem all along.
- Crown cracks that go years before anyone notices. The crown is the first line of defense against water, and a hairline crack can sit there quietly for five or six Greenwich winters. A Level 2 camera inspection catches it before the water reaches the smoke chamber.
- Wrong parts on factory-built chimneys. Backcountry homes built after 1980 often have factory-built chimney systems with specific manufacturer requirements. A generic cap or liner voids the warranty and fails early. We match components to the original spec.

FAQs About Chimney Repair in Greenwich
The National Fire Protection Association standard is once a year, and that holds for Greenwich even if you only burn occasionally. Coastal moisture accelerates crown and flashing deterioration, and pre-war masonry in neighborhoods like Riverside and Old Greenwich ages faster than newer systems. Call (830) 251-4560 to book an inspection, and we’ll send you the photo report afterward.
Third-degree creosote, the hard, shiny, tar-like glaze, usually can’t be brushed out with standard sweep methods. In many cases we address it with a rotary chain system or recommend a HeatShield cerfractory sealant application to restore the flue liner after the creosote is addressed. We’ll show you the camera footage before we recommend anything, and the written price covers what we actually do, nothing else.
We inspect the chimney, usually with a Level 2 camera inspection, document the condition with photos, and identify the specific system you have. Then we write the price, in writing, before any tool comes off the truck. You review it, you approve it, and that number is the number on the invoice. No moving the price at the door.
A hairline crack in the crown doesn’t usually demand an emergency repair, but it should be addressed before the next freeze-thaw season in Greenwich. Water that enters a hairline crack will freeze, expand, and widen the crack each winter. If we inspect it and determine it can safely wait, we’ll tell you that straight and give you a written note. Call (830) 251-4560 and we’ll take a look.
Both. Greenwich’s backcountry homes from the 1980s onward often have factory-built chimney systems, and we service those with manufacturer-spec components from Olympia Chimney and Famco. Pre-war masonry chimneys in Riverside, Old Greenwich, and along the Post Road get the full masonry treatment. We identify the system before we quote anything.
