Chimney Repair in Greenwich - Inspected on Camera, Then Priced in Writing

Trusted Chimney Repair for Greenwich Homeowners

Chimney repair in Greenwich, CT typically runs between $450 and $3,800 depending on what’s actually wrong: a flashing leak might cost a few hundred dollars, while a partial rebuild near the crown can push into the low thousands. We’ve inspected and repaired more than 38,000 chimneys since 2009, and in Greenwich specifically we see the same three issues repeat across Cos Cob, Riverside, and Old Greenwich: failed flashing at the roof line, spalling brick from freeze-thaw cycles, and mortar joints that have turned to sand. Corrine Halstead leads our Greenwich team, and she’ll tell you straight: most repairs in Fairfield County don’t need a full rebuild when caught early. If you’re seeing water stains on the ceiling near the chimney or mortar bits in the firebox, call (516) 399-5497 and we’ll get a camera down the flue to show you exactly what’s happening.

Call (516) 399-5497

Every repair we quote comes with a written price, a written scope, and a written warranty under Haven Standard Clause 1. No exceptions, no “we’ll see when we get up there.” You get the number before we start, and you get a documented photo record when we’re done. That’s been our practice since 2009, and it’s why homeowners across Greenwich, Byram, and Port Chester call us when they want evidence, not assurances.

Key Takeaways

• Camera inspection first: We don’t recommend repairs until we’ve put a camera down the flue and shown you the footage (Haven Standard Clause 4).
• Written price before work starts: You’ll know the exact dollar amount, scope, and warranty terms before anyone touches the chimney.
• Local to Greenwich: We work in Greenwich, Byram, Cos Cob, Riverside, Old Greenwich, and surrounding Fairfield and Westchester towns.
• 365-Day Done Right Promise: If it’s not done right, we make it right. It’s stamped on every job.
• Repairs, not upsells: If your liner is fine, we’ll say so. If it can wait, we’ll tell you that too, with the camera footage to prove it.

What Our Chimney Repair Service Includes

Chimney repair covers a lot of ground, from a single cracked brick to a full tear-down and rebuild. What follows is what we actually do for Chimney Repair in Greenwich, the conditions we typically find, and how we address each one. If you’re not sure which category your chimney falls into, start with a camera inspection and we’ll walk you through what the footage shows.

Mortar Repointing

Mortar Repointing is the process of removing deteriorated mortar from between the bricks and replacing it with fresh, correctly-mixed mortar. Over decades, Greenwich winters push moisture into the joints, where it freezes and expands, and the mortar slowly crumbles out. We grind out the old joints to a proper depth, pack in new mortar that’s matched to your existing brick’s hardness and color, and tool it so it sheds water the way it should. If your chimney looks fine from the street but sheds sandy grit onto the roof after a rain, repointing is likely your fix.

Spalling Brick Repair

Spalling Brick Repair addresses what happens when the face of a brick pops off, leaving a rough, recessed surface behind. It happens when water gets trapped inside the brick and freezes, and it’s common in Greenwich chimneys that were built before modern water repellents existed. We remove the damaged brick, clean the cavity, and set a replacement brick in fresh mortar, matching the size, color, and texture as closely as the supply houses allow. Left unaddressed, spalling spreads inward until the chimney loses structural integrity.

Chimney Waterproofing

Chimney waterproofing is the single most cost-effective repair we do in Greenwich. It’s a penetrating, vapor-permeable treatment brushed or sprayed onto the masonry that lets water vapor escape from inside while keeping rain and snowmelt out. We apply it after any masonry repair, because it locks in the new work and dramatically slows the freeze-thaw cycle that causes spalling and joint failure. This is the repair that should have been done when the house was built, and it’s the one Corrine recommends most often after seeing what Fairfield County weather does to untreated brick.

Flashing Repair

Flashing is the metal band where the chimney meets the roof, and it’s the number one source of chimney leaks in Greenwich. We see it constantly: aluminum flashing that’s lifted, corroded or was never stepped and counter-flashed correctly in the first place. We remove the old flashing, install proper step and counter-flashing in copper or aluminum, and seal the transition so water has no path into the roof deck. If you’ve got a water stain on the ceiling near the fireplace, flashing is the first thing we check.

Chimney Rebuilding

A partial rebuild is required when the top few feet of masonry, usually from the roofline up, have deteriorated past the point where pointed repairs make sense. We tear down to sound brick, rebuild with new brick and fresh mortar, and install a proper crown and cap while we’re there. A full rebuild, from the firebox up, is rarer and usually follows decades of neglect or a structural failure in the foundation. Either way, you get a written price and a photo record, so what we say we found is what you see.

Tuckpointing

Tuckpointing is the more refined version of repointing, where we match both the mortar joint and a thin contrasting line in the joint face for older or decorative brickwork. It’s common on Greenwich homes with historic or architecturally distinct masonry where the look matters as much as the waterproofing. We cut out the old joint, fill it with a color-matched mortar, and tool the thin line that gives tuckpointing its name. It’s slower work and costs more per linear foot than standard repointing, but it’s the correct repair when aesthetics are part of the brief.

Signs You Need Chimney Repair Right Now

• Water stains on the ceiling or walls near the fireplace. This usually means flashing failure, a cracked crown, or a stucco/frame gap at the roofline. Water is already inside the house, which means the inside of the chimney is getting wet too, and wet masonry fails faster. The sooner it’s sealed, the cheaper the repair.
• Bits of mortar or brick in the firebox or on the roof. If you find sandy grit or small brick fragments on the floor of the fireplace, the joints above are actively failing. That material is coming from somewhere, and the somewhere is the structural skin of your chimney. It will not stop on its own.
• A musty smell from the fireplace after heavy rain. That’s the smell of water-soaked masonry and creosote drying out. It means water is getting in somewhere, and a damp flue accelerates liner corrosion. A camera inspection will find the entry point quickly.
• White staining on the exterior brick. That’s efflorescence: mineral salts left behind when water evaporates out of the brick. It means the masonry is absorbing water and has been for a while. Waterproofing and repointing are the standard fix, once we confirm the source of the moisture.
• Cracks in the chimney crown or a missing cap. The crown is the concrete slab at the top of the chimney, and the cap is the metal cover that keeps rain and animals out. If either is cracked or gone, the flue is open to rain, snow, and birds, all of which accelerate every other repair on this list.

Our Chimney Repair Process - Step by Step

1. 1
   Camera inspection and photos. We run an NFPA 211 Level 2 camera inspection on every visit, no exceptions. You’ll see the flue interior on the screen while we do, and the footage becomes part of your documented record under Haven Standard Clause 4. Nothing gets recommended off a roofline glance.
2. 2
   Written scope, written price, written warranty. Before any work begins, we hand you a written document listing exactly what’s wrong, what we’ll do, what it costs, and what’s covered under the 365-Day Done Right Promise. That’s Haven Standard Clause 1, and it’s not optional in our book.
3. 3
   Repair work with background-checked, uniformed techs. A named technician is assigned to your job, with a text sent when they’re on the way. They’re licensed, insured, and trained to the Haven Standard. You’ll never wonder who’s on your roof or whether they’re qualified to be there.
4. 4
   Documented photo record on completion. Once the work is done, we document it the same way we documented the damage: with the camera. You’ll have before-and-after images showing the repair, the materials used, and the condition of the surrounding masonry. The record is yours to keep.
5. 5
   Follow-through on the 365-Day Done Right Promise. If anything we repaired fails within a year because of our workmanship, we come back and correct it. That promise is stamped on the paperwork, not mentioned in passing. It’s the backstop that makes a written warranty actually mean something.

Brands We Service for Chimney Repair

We work with materials from DuraFlex and HeatShield on liner-related repairs because they’ve held up well in Fairfield County conditions and their specs are consistent. When a chimney needs a new stainless liner, we install DuraFlex systems and document the install with the same camera we used to find the problem. For parging and smoke chamber repairs, HeatShield’s cerfractory system lets us resurface without tearing out masonry, which matters a lot in older Greenwich homes where the structure around the flue shouldn’t be disturbed more than necessary.

We also keep Copperfield and Famco components in the truck for cap and crown work, because those brands have proven themselves over years of Greenwich winters. Whether you have a chimney built with those products or any other make, the process is the same: we inspect with the camera, give you a written price, do the work, and hand you the photo record. The brand matters less than the condition of what’s installed, and we’ll show you that condition before we touch anything.
