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.

Why Level Two Chimney Stamford Is Harrison’s Preferred Chimney Repair Company

Harrison homeowners call us because we put the camera down the flue and hand them the evidence before asking for a dime. That’s been our practice since 2009, and it’s written into the Haven Standard as Clause 4: a documented photo record on every job, whether it’s a routine sweep or a full rebuild. Corrine Halstead has built the team around one idea: if you can’t show the homeowner the crack, the damaged liner, or the failed flashing, you don’t have the right to recommend the repair.
We’ve worked chimneys all over Harrison: colonials off Harrison Avenue, capes in West Harrison, and estate-scale Tudors in Purchase where three fireplaces share one masonry stack. Our techs arrive in uniform, background-checked, with a named contact assigned to your job and a text when they’re on the way. That’s Haven Standard Clause 2: arrive on schedule, verified crews. We don’t subcontract, and we don’t send a salesperson to “diagnose.” The person with the camera is the person doing the repair.
Every estimate is written. The scope, the price, the warranty: all in writing before work starts, every time. That’s Clause 1 of the Haven Standard. Bring us a competitor’s written quote and we’ll give you a free second opinion, and we’ll walk you through exactly what the other shop proposed, line by line.

AfterOur Chimney Repair Services in Harrison
Our Chimney Repair team handles the full spectrum of masonry and flue work Harrison homes require. Here’s what we do most often in this town.
Mortar Repointing
The mortar beds on Harrison chimneys take a beating every winter. When temperatures drop into the teens and then climb back above freezing, moisture in the joints expands and contracts, and the mortar cracks loose. That’s why so many Harrison chimneys show eroded joints within 15-20 years of their last repoint. We cut out the failed mortar to a proper depth and pack in fresh, breathable mortar matched to the original. Typical repointing in Harrison runs $1,200-$2,800 depending on chimney height and joint condition.

Spalling Brick Repair
Spalling, which is what happens when brick faces pop off, usually means water got into the brick and froze. Harrison’s inland winter weather, with hard freeze-thaw cycling, accelerates this far more than what you’d see in coastal Westchester towns. On Purchase estate homes especially, we see spalling concentrated at the chimney crown and the upper courses where rain and snow sit longest. We replace the damaged brick, restore the bedding, and address the water intrusion that caused it, whether that’s a failed crown, cracked flashing, or both.

Chimney Waterproofing
A lot of Harrison homeowners ask if waterproofing is worth it. It is, if the masonry is in sound condition first. We don’t waterproof over spalling brick or cracked mortar; that just traps moisture and makes things worse. But on a chimney that’s sound, we apply a vapor-permeable siloxane-based waterproofing that keeps rain and snow out while letting the masonry breathe. In Harrison’s Blind Brook watershed, where ground moisture and mature tree canopy keep air humidity higher than you’d expect, this matters year-round.

Flashing Repair
Harrison’s steep Tudor and Colonial Revival rooflines make flashing one of the most common failure points we see. When flashing rusts, lifts, or was poorly installed around tight roof penetrations, water runs straight down the masonry and soaks the brick. On a 1930s Tudor in Purchase, that’s a fast path to spalling and interior water damage. Our flashing work on Harrison homes typically runs $450-$1,400, and we use Copperfield flashing when replacement is needed, which holds up far better in freeze-thaw exposure than big-box galvanized.

Trusted Brands We Service in Harrison

We specify materials we’d put on our own chimneys, not whatever the supply house has in stock. For Harrison relines, we use DuraFlex stainless liners; for crown and flashing work, we prefer Copperfield. When a chimney needs partial repair rather than full replacement, HeatShield gives us a tested, warrantied option that’s often a fraction of a full reline. Because we buy through the Haven network, those material costs stay honest. The written quote you get includes the specific brand and part, not just “liner.”
Common Chimney Repair Problems We See in Harrison Homes
- Shared-stack cross-contamination. In Purchase and older Harrison neighborhoods, multiple fireplaces and appliance flues share one masonry stack. When a clay tile liner cracks behind the smoke chamber, a neighbor’s boiler exhaust can migrate into your fireplace opening during low-draft conditions.
- Third-degree creosote glaze. The lightly used estate fireplaces in Purchase often burn only on weekends and holidays. Smoldering, low-temperature fires deposit a tar-like, hardened creosote that mechanical brushes can’t remove and that requires chemical treatment or mechanical removal before any repointing or relining.
- Flashing failure at tight roof penetrations. Steep Tudor and Georgian rooflines put flashing under repeated stress from ice dams and snow load. Once the flashing lifts, water carries mortar fines and brick dust down the chimney face, which is a classic sign of ongoing masonry deterioration.
- Crown deterioration. Older Harrison chimneys frequently lack a proper poured crown with a drip edge. Without one, water pools on the top course of brick, and winter’s freeze-thaw does the rest.
Pricing for Chimney Repair in Harrison, NY

What you’ll pay depends on what the camera finds. That’s not a dodge; it’s how masonry works. A crack you can’t see from the ground is a different job than loose flashing. That said, here’s what Harrison homeowners should expect:
| Chimney Repair Service | Typical Range in Harrison |
|---|---|
| Flashing repair or replacement | $450-$1,400 |
| Mortar repointing (full chimney) | $1,200-$2,800 |
| Spalling brick repair (small section) | $350-$900 |
| Chimney crown repair/rebuild | $800-$1,600 |
| Chimney waterproofing (after prep) | $350-$800 |
| Partial chimney rebuild (above roofline) | $1,800-$3,800 |
| Single flue stainless reline | $2,200-$4,500 |
Multi-flue relines on a shared Harrison stack are priced per flue, and we discount the second and third flue when they’re done in the same visit because the access and staging are already in place. Every estimate is free, written, and itemized, and it shows the brand, the scope, and the warranty before you approve anything. Call (914) 537-8463 for your free estimate from Chimney Repair in Harrison.

FAQs - Chimney Repair in Harrison
The repair is a targeted rebuild of your flue liner or a full reline of that flue, depending on where the crack is. In shared-stack construction common in Harrison’s older homes, the masonry stack is structurally shared but each flue should be its own separate clay tile liner. When your clay liner cracks behind the smoke chamber, low-draft conditions pull your neighbor’s boiler exhaust into your flue instead of up and out. We verify this with a camera scan showing the crack, then rebuild or reline your flue with DuraFlex so it’s separated and sound. Call (914) 537-8463 to schedule an inspection; we’ll show you the footage before recommending anything.
That flaking, called spalling, is water freezing inside the brick and blowing the face off. Purchase estate chimneys take the worst of it because the homes sit in Westchester’s inland corridor, where winter temps drop into the teens and climb back above freezing repeatedly. Water from a failed crown or flashing soaks the brick, freezes, expands, and pops the face. We fix it by repairing the water entry point first, replacing the damaged brick, and often applying a breathable waterproofing to slow future damage. Call (914) 537-8463 for a free written estimate.
Yes, it’s a repair issue. That tar smell is third-degree creosote glaze, the hardened, tar-like byproduct of smoldering low-temperature fires. It’s common in lightly used Harrison estate fireplaces that sit all week and burn hot all weekend. Rain adds moisture, which activates the odor and pulls it into the house. This creosote requires mechanical removal, and once it’s out, we recommend a camera inspection to check the liner behind it, because glaze this bad usually means the flue has seen years of low-temperature burning and needs a close look. Call (914) 537-8463 to book a sweep and inspection.
In most Harrison homes, yes. Flashing failure is a water-entry problem, not a structural one, unless the masonry behind it has already spalled badly from years of exposure. We replace the flashing with Copperfield material, check the underlayment at the roof penetration, and repoint any brick that’s lost mortar near the flashing line. The repair typically runs $450-$1,400. Full rebuilds are only needed when the chimney has already lost substantial masonry or the crown has failed. Call (914) 537-8463 for a free estimate and we’ll show you exactly what the camera finds.
We run a camera down each of the three flues separately. That’s the only answer, and it’s why we’ve made camera-scan documentation the default on every inspection since 2009 under Haven Standard Clause 4. In a 1940s Harrison chimney with three clay tile flues in one stack, the failure rarely hits all three at once. Usually one flue shows cracking or spalling at the smoke chamber, while the other two still hold. We reline only what the footage shows needs relining. If this is a fireplace you rarely use, and the flue is only serving that fireplace, you may be able to defer it; if it’s venting a furnace or boiler, you act on it now. Call (914) 537-8463 and we’ll put the camera down all three flues and show you the footage on site.
