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 Armonk’s Preferred Chimney Repair Company
Armonk homeowners tend to ask harder questions than most, and we’re built for that. Every job we do here includes a camera-scan inspection that produces a documented photo record you keep. Clause 4 of the Haven Standard has required this on every visit since 2009, long before anyone in Westchester asked for it. You see exactly what we see inside the flue, the smoke chamber, and behind the crown before you approve a dollar of work.
Our crews know the terrain. From Route 22 to the winding approach roads off Route 128, we’ve worked on 1960s colonials off Overlook Road, 1980s contemporaries near Wampus Lake, and everything between. That local familiarity matters when you’re scheduling a repair on a property that drops three feet at the back and puts the chimney on a north-facing elevation. Corrine Halstead, our owner, insists that every Armonk customer gets the same thing: a name, a phone number, and a written scope of work before anything begins.
We also know that Armonk homeowners are comparison shoppers. That’s fine. Bring us a competitor’s written estimate and we’ll give you a free second opinion on it. If it’s fair, we’ll tell you. If it misses something, we’ll show you in photos.
Our Chimney Repair Services in Armonk

Every chimney repair we do in Armonk starts with the camera. Here’s what we’re typically fixing once the inspection is done.
Mortar Repointing
Armonk’s freeze-thaw cycles are harder on mortar joints than almost any other town we serve in the region. The elevated, hilly terrain keeps chimneys colder longer, and older homes built in the 1960s through 1980s used mortar mixes that break down after 40 to 50 years. Repointing means cutting out the deteriorated joints and replacing them with the correct mortar. On an Armonk chimney, it’s usually $800-$2,200 depending on height and access. Skip it, and water keeps getting in, which is how small cracks become spalling brick and full rebuilds.

Spalling Brick Repair
Spalling is what happens when moisture trapped inside the brick freezes, expands, and blows the brick face off in chunks. It’s common on Armonk properties where chimneys sit on north-facing elevations that never dry out fully during winter. We replace the damaged brick one unit at a time, matching the existing color and texture as closely as the original masonry allows. Repairs in Armonk generally run $600-$1,800 per affected area, and we always check for the underlying moisture source first. Patching spalled brick without fixing the water entry is a waste of your money.

Chimney Waterproofing
Given the leaf load Armonk chimneys carry each fall, waterproofing is the most underused repair in town. We apply a vapor-permeable waterproofing agent, typically ChimneySaver, that lets moisture out but stops rain and snowmelt from soaking in. On the large estate homes common around Armonk, we typically waterproof all flues on the property at once, which runs $450-$950 depending on chimney count and square footage. It extends the life of new mortar and brick work for a decade or more.

Flashing Repair
Flashing is the metal where chimney meets roof, and in Armonk it fails more often than in White Plains or Rye. Blame the canopy cover. Heavy falling branches and accumulated debris shift flashing over time, and when water gets through, it travels down the interior chimney structure before you ever see a stain on the ceiling. Repairs in Armonk typically run $400-$1,500. We remove the old flashing, inspect the underlying sheathing, and install new step and counter flashing sealed correctly to the masonry. It’s one of the most common repairs we perform before October in this area.

AfterTrusted Brands We Service in Armonk
We stock and install materials from DuraFlex and Copperfield for flue liner work, and HeatShield for resurfacing smoke chambers that show cracking. These aren’t entry-level parts. They’re what we’d put in our own chimneys. Because we order through Haven’s buying network, we keep customer pricing honest in Armonk without juggling suppliers. When your repair needs materials, we carry common Armonk sizes for the older chimneys found on these estate lots, which keeps turnaround faster than a special-order line.
Common Chimney Repair Problems We See in Armonk Homes

- Leaf-clogged spark arrestors and crowns. Armonk’s wooded lots drop heavy debris on chimney crowns every fall. Blocked spark arrestors trap moisture against aging mortar, which accelerates damage before the first hard freeze.
- Freeze-thaw spalling on north-facing elevations. The hilly terrain around North Castle keeps north-facing chimney walls shaded and cold. Water inside the brick freezes, expands, and pops the face off, a failure mode we see constantly here.
- Third-degree creosote glaze in multiple flues. Armonk homeowners burn a lot of local oak and maple, much of it not seasoned long enough. That produces a hard, glossy creosote that adheres to clay tile liners and overwhelms older smoke chambers.
- Original clay tile liners cracking from thermal cycling. Most Armonk homes built between 1960 and 1990 still have original clay liners. Forty to sixty years of heating cycles crack them, and once cracked, they fail inspection and can vent into the house.

FAQs - Chimney Repair in Armonk

A typical Armonk estate home has two to four flues: formal living room, family room, master suite, sometimes a basement fireplace or a separate oil flue. That means a repair here isn’t a single-chimney job. When we inspect one flue that’s failing, we camera-scan every flue on the property because they’re usually the same age and the same clay tile material. Quoting a repair without looking at all of them would miss half the picture. If all three flues need repointing, for example, we’ll price each line separately. Call (914) 537-8463 and we’ll scope the full property at once.
Flashing fails more often in Armonk because the mature tree canopy drops heavy debris that sits on roof intersections and chimney bases. Add the hilly terrain, which pitches roofs at steeper angles and drains water unevenly, and flashing takes more stress than it does in flatter towns like Rye or White Plains. When water works under the flashing, it travels down inside the chimney structure and shows up as a ceiling stain or damp smell near the fireplace. We see it constantly. It’s repairable, but it’s not a DIY fix. Call us for a camera inspection and a written price before you spend anything.
Usually yes, provided the clay tile liner is either intact or we install a properly sized liner. We can run a gas insert through a relined flue, and on many Armonk homes we do the liner and the insert in one call. What you don’t want is venting a gas appliance into an old, cracked clay liner that’s leaking into the walls. Our camera scan shows us whether the existing liner can carry a gas appliance, and if it can’t, we quote the DuraFlex stainless liner work. You’ll have a written price for the whole scope before anything starts.
A Level 2 inspection covers the interior of every flue, the smoke chamber, the damper, the crown, the flashing, and the clearances to combustibles in the attic and around the appliance. On an Armonk multi-flue property, that means we bring the camera down each flue separately, photograph everything, and hand you a documented record when we’re done. We’ve been doing camera-documented inspections since 2009, and Clause 4 of the Haven Standard requires a photo archive on every visit. That record is yours, whether or not you proceed with repairs.
Even properly seasoned hardwood produces creosote, and Armonk’s dense, wet autumns mean wood stored outdoors never dries as well as homeowners think. The real issue is that a multi-flue home burning wood in several fireplaces each winter accumulates creosote faster than a single-flue home. An annual cleaning also gives us the chance to spot cracked liners, failing flashing, or crown damage before they become $3,000 repairs. On a large Armonk property, skipping a year is how a $350 cleaning becomes a $4,500 liner job. Call (914) 537-8463 to schedule, and we’ll work around your winter burning schedule.
