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 Stamford
Chimney repair in Stamford runs anywhere from $300 for a small mortar repointing job to $4,800+ for a partial rebuild, and most repairs we perform fall between $850 and $2,600. Salt air off Long Island Sound, 25-35 freeze-thaw cycles per winter, and 1920s-1950s masonry chimneys that were often modified without proper liners mean Stamford homeowners face repair issues inland Connecticut towns rarely see. If you’re in Springdale, Shippan Point, Glenbrook, or anywhere else in Stamford, call us at (516) 399-5497 and we’ll put a camera down your flue, show you exactly what’s there, and hand you a written price before any work begins.
Why Level Two Chimney Greenwich Is Stamford’s Preferred Chimney Repair Company
We’ve inspected and repaired chimneys in Stamford long enough to know this city’s housing stock and what Long Island Sound does to it. The brick colonials in Glenbrook and North Stamford, the waterfront homes on Shippan Point and the Cove, the cape cods in Springdale: many of these chimneys were built well but modified poorly during the 1970s and 80s, and the salt-humid air has been working on the mortar ever since. Our camera scan is NFPA 211 Level 2, and it’s included on every visit, not sold as an add-on. You see the footage. You get the written scope, written price, and written warranty before the work starts, which is Clause 1 of the Haven Standard, the inspection and pricing standard we’ve operated under since 2009.
Stamford homeowners tend to call us after they’ve already had one company tell them they need a full rebuild and they want a second set of eyes. We bring a competitor’s written estimate and we’ll give you a free second opinion on it. Corrine Halstead runs our repair division, and every technician who shows up at your door in Stamford is background-checked, uniformed, and assigned to your job by name. You’ll get a text when we’re on the way. And when we’re done, you’ll have a documented photo record of everything we found and everything we did. That’s Clause 4 of the Haven Standard, and it’s been our practice on every one of the 38,000+ chimneys we’ve inspected and cleaned since 2009.
Our Chimney Repair Services in Stamford
Most Stamford chimney repairs fall into a few categories: deteriorated mortar joints, spalling brick, water intrusion through worn crowns or flashing, and rusted-out caps. Here’s how we handle the four most common repairs we perform across Stamford’s neighborhoods.
Mortar Repointing in Stamford
Mortar repointing is the most common repair we do in Stamford, especially on the 1920s-1950s brick chimneys that dominate Springdale, Glenbrook, and North Stamford. Repointing means raking out deteriorated mortar joints and packing in fresh mortar, and at the top of a coastal chimney, those joints are taking salt spray, rain, and freeze-thaw stress every winter. On Shippan Point, we routinely see mortar that should’ve lasted 30 years crumbling in 15 because salt keeps the joints damp and every hard freeze pushes them further apart. A typical repointing job on a Stamford chimney runs $750-$2,200 depending on how many courses are involved and how much scaffold work the roofline requires.
Spalling Brick Repair
Spalling is what happens when water gets into the brick face, freezes, and pops the outer layer off. It’s not cosmetic, even though it looks that way at first. In Stamford, the salt-humid air keeps brick faces saturated longer than inland towns, which speeds up the freeze-thaw damage. We rebuilt the crown and repointed the upper ten courses on a 1938 brick colonial in Glenbrook after our camera showed salt-driven spalling and a corroded Famco cap that had let water into the smoke chamber. We installed a stainless Olympia Chimney cap, replaced the flashing with copper, and waterproofed the masonry with Gelco. That repair was $4,300 and it’ll hold for decades. If we’d reused galvanized materials, it would’ve been a $1,800 patch that failed in five years.
Chimney Waterproofing
Waterproofing is not an upsell in Stamford. It’s the difference between repairing your chimney once and repairing it every eight years. We use Gelco masonry sealer, which is vapor-permeable, meaning water stays out while moisture inside the brick can still escape. That’s critical because sealing a coastal chimney with the wrong product traps salt moisture inside the masonry and accelerates spalling. A chimney waterproofing treatment in Stamford typically runs $450-$900 depending on chimney size and surface condition.
Flashing Repair
Flashing is the sheet metal where the chimney meets the roof, and on Stamford’s waterfront and near-water neighborhoods, it’s the first thing to go. Galvanized flashing on Shippan Point routinely corrodes through in 8-12 years. Homeowners who moved here from Danbury or Waterbury are often stunned by that timeline, because the same flashing lasted 20 years inland. We replace flashing with copper or stainless on Stamford jobs, because salt air makes galvanized a bad investment. Flashing repair in Stamford runs $650-$1,800 depending on roof pitch, chimney placement, and whether we need to cut into roofing to properly step-flash the chimney. We never caulk over failed flashing and call it a fix.

BeforeAfterTrusted Brands We Service in Stamford
We stock parts and materials from Famco, Copperfield, and DuraFlex, and we install them in Stamford homes every week. When a Shippan Point cap has rusted through, we’re not waiting two weeks on a specialty order; our technicians arrive with stainless and copper options on the truck. Our Chimney Repair crews also carry DuraFlex liners for homes in Springdale and Glenbrook where 1970s oil-to-gas conversions left clay tile flues that fail inspection. Materials are sourced through the Haven buying network specifically to keep pricing honest for Stamford homeowners.
Common Chimney Repair Problems We See in Stamford Homes
- Salt-corroded flashing and caps. Homes within two miles of Long Island Sound, especially on Shippan Point and the Cove, lose galvanized flashing and steel caps in half the time inland homes do. The corrosion lets water behind the brick, and by the time you see stains on the ceiling, the damage is already inside the chimney.
- Spalling brick from coastal freeze-thaw cycling. Stamford gets 25-35 freeze-thaw cycles per winter, and the salt in the air keeps brick faces damp during every one of them. That’s why spalling on Stamford chimneys looks worse at the top few courses than anywhere else.
- Unlined or improperly lined flues in converted colonials. The 1970s and 80s corporate migration boom brought thousands of renovations to Stamford, many of which converted coal or oil chimneys to gas without installing proper stainless liners. Modern gas appliances venting into oversized or cracked clay tiles fail inspection under current CT code.
- Crown cracking and water pooling. Original crowns on 1930s-1950s Stamford chimneys are usually too thin and lack proper overhang, so water pools and cracks them. Once a crown is cracked, freeze-thaw works it open further every winter, which is why crown rebuilding is so common in Glenbrook and North Stamford.
Pricing for Chimney Repair in Stamford, CT
Here’s what Stamford homeowners can expect to pay. Mortar repointing: $750-$2,200. Flashing replacement: $650-$1,800. Crown rebuild: $900-$2,400. Chimney waterproofing: $450-$900. Full chimney rebuild above the roofline in Stamford: $3,200-$6,800, with partial rebuilds running proportionally cheaper. Waterfront homes on Shippan Point and the Cove trend toward the higher ends because we’re using copper or stainless materials instead of galvanized. Every job gets a written price before we start, and that price doesn’t move unless we find something structural we show you on camera and you approve in writing.

FAQs - Chimney Repair in Stamford
Long Island Sound wraps around Shippan Point on three sides, which means salt-laden air hits your chimney cap from every direction nearly year-round. Salt accelerates galvanic corrosion in steel and galvanized metal, and the constant salt-humid air during fall and winter means there’s never really a dry season for that cap. On Shippan Point, we routinely find standard galvanized caps corroded through in 8-12 years. The fix is stainless or copper, not another galvanized cap. Call (516) 399-5497 if you want us to take a look and show you the difference on camera before you decide.
If the conversion didn’t include a stainless liner, there’s a very good chance your gas appliances are venting into an oversized or cracked clay tile flue, which fails inspection under current CT code. During the 1980s, many Stamford conversions were done quickly and cheaply, without relining. We can run a camera up the flue and show you exactly what’s in there. If a liner is needed, we install DuraFlex stainless liners and you’ll see the before and after photos. Call (516) 399-5497 to schedule a Level 2 camera inspection with the written report included.
Yes, and in Stamford that’s often the right call. Salt air and freeze-thaw hit the top few courses hardest, so we frequently repoint the upper eight to twelve courses and leave the lower masonry intact. Our camera inspection tells us whether the lower joints are sound or if there’s hidden damage we should address now. We won’t ask you to repoint brick that doesn’t need it. A partial repoint like this typically runs $750-$1,400.
Annually, and that’s the NFPA 211 recommendation everywhere, but on the Stamford waterfront it’s not a formality. Salt corrosion moves fast, so a cap or flashing that was fine last year can be leaking water this year. Annual Level 2 inspections catch that before water intrusion becomes a rebuild. Our camera scan and photo record are included on every visit, so you have documentation to compare year over year. The 365-Day Done Right Promise backs every job we do in Stamford.
For most Stamford chimneys, yes, it’s still worth it. A cap and flashing protect the top and the roofline, but they don’t stop wind-driven salt rain from soaking into the brick face. Waterproofing with a vapor-permeable sealer like Gelco keeps water out while letting the masonry breathe, and it’s the single most cost-effective way to slow spalling on a coastal chimney. A Stamford chimney waterproofing treatment runs $450-$900, and it’s cheaper than repointing every few years.
