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.

Our Chimney Repair Services in Monsey
Most Monsey chimneys we look at fall into one of these repair categories. Here’s what each one means and what it costs when we do it here.
Mortar Repointing
Monsey’s oldest ranch homes have been through 60 winters of freeze-thaw cycles, and the mortar joints are usually the first thing to go. Mortar repointing means cutting out the soft, crumbling joints and troweling in fresh mortar that matches the original. For a standard single-flue chimney in Monsey, repointing runs $180-$340 depending on how high the damage runs and whether we need scaffolding on a two-story split-level. Done right, it keeps water out and adds years before any rebuilding is necessary.
We see the worst of it on the west side of the hamlet, where northwest winds off the Ramapo Mountains drive rain directly against exposed brick faces. If your chimney faces that direction, you’ll notice the mortar eroding faster than on the sheltered side.

Spalling Brick Repair
Spalling is when brick faces crack off and fall, leaving pitted, crumbling surfaces. It happens when water gets inside the brick and freezes, expanding and blowing off the face. Monsey’s sustained freezing winters make this common on any chimney over 30 years old. Repairing spalled brick costs $35-$70 per brick face replaced, and a typical repair section runs $250-$600.
If the spalling is localized, we cut out the damaged brick and set replacements into fresh mortar. If it covers the whole structure, we’ll tell you honestly whether the chimney is a candidate for rebuilding or whether waterproofing will buy you time.

Chimney Waterproofing
Brick is porous. Rain soaks in, freezes, expands, and cracks things. Monsey gets cold, snowy winters that punish chimneys. A breathable waterproofing treatment like what we apply with the ChimneySaver brand runs $300-$550 for an average chimney here. It keeps water out while letting the masonry breathe, so trapped moisture doesn’t do worse damage inside the brick.
Waterproofing is the single best way to stretch the life of an older Monsey chimney that’s still structurally sound. We recommend it after any repointing or rebuilding job. It’s not an upsell. It’s the difference between another repair in five years or fifteen.

Flashing Repair
This is the most common chimney repair in Monsey, and the one most homeowners don’t notice until water spots appear on the ceiling. Flashing is the metal where the chimney meets the roofline. When it fails, water runs down the interior drywall and traces back to the firebox. Flashing repair here runs $400-$900, with full replacement on the higher end when the old flashing is torn or improperly stepped.
Monsey’s mix of steep ranch roofs and added sections from expansions means we see a lot of flashing that was never re-installed correctly after a renovation. On a kitchen addition, the original flashing is often bent, reused, or shingled over. We strip it, install proper step and counter flashing with brand-name materials, and water-test it before we come off the roof.

Common Chimney Repair Problems We See in Monsey Homes
- Shared flues from kosher-kitchen additions. Monsey’s housing stock has been modified more than almost any community we serve. Secondary kitchens for kosher meal preparation mean added exhaust and heating appliances tied into flues that were never sized for them. The result is an overloaded flue that builds creosote twice as fast and pulls a weak draft.
- Northwest winds off the Ramapo Mountains. Homes on the western-facing slopes get hit with strong channeled winds that push down the flue. Backdrafts push smoke and creosote into the attic framing. We see this on the Saddle River Road corridor more than anywhere else in the hamlet.
- Cracked terra-cotta liners from freeze-thaw cycling. Those 1950s-1970s ranch chimneys often still have their original clay tile liners. Monsey’s winters split them. Water follows the cracks, spalls the brick outside, and sends damp into the smoke chamber. Liner inspection should be part of every repair call here.
- Heavy creosote loading in wood stoves. Monsey burns more wood than most of Rockland County. Homes off the main gas lines and older ranch houses with stoves running November through March accumulate third-degree creosote faster. That’s a chimney fire waiting for a Saturday morning. Catch it with an annual sweep, and for stoves, twice a year if you burn a lot.
Pricing for Chimney Repair in Monsey, NY
Here’s the honest range for the work we do most in Monsey. Mortar repointing runs $180-$340. Flashing repair runs $400-$900. Spalling brick repair runs $250-$600 depending on how many faces need replacing. Chimney waterproofing runs $300-$550. A full chimney rebuild above the roofline starts around $2,500 and goes up from there based on height and material. A flue liner installation, which often accompanies these repairs, runs $1,800-$4,000 depending on the liner material and access.
What affects the price: how tall the chimney is, whether we need a lift or scaffolding, and how much of the original masonry is still sound. We give an upfront price before a single tool comes off the truck, and the number you hear on the phone is the number on the invoice. There’s no trip charge for calls inside the county, and we offer $40 off any repair over $200. Seniors and veterans always get 10% off.

FAQs - Chimney Repair in Monsey
Yes. We schedule all work around Shabbat and the full Jewish holiday calendar. No work begins Friday afternoon or on yom tov. If you tell us your family’s observance schedule, we’ll work the job around it. We’ve been doing this for Monsey customers for decades, and the calendar is built into how we book. Call (845) 599-0832 and we’ll find a date that works for you.
Because adding a second, kosher kitchen usually means adding a second stove, oven, or exhaust system, and contractors often tie those new appliances into the original single-flue chimney without upgrading the liner. That leaves an unlined or undersized flue serving double duty, which builds creosote fast and compromises the draft. We inspect the liner on nearly every post-renovation chimney we touch in Monsey, and most need at least a partial reline. Call for a camera inspection and we’ll show you exactly what’s inside.
The northwest winds that channel off the Ramapo range come down hard on homes built on the western-facing slopes and along exposed sections of Route 306. High wind pressure at the chimney crown can overcome the updraft and force smoke back down the flue into the house. We address it with taller flue terminations, properly sized caps, and sometimes wind-resistant cap models. If your living room smells like smoke on windy winter nights, that’s the Ramapo wind at work. A flue cap and draft adjustment usually fixes it.
Yes. Wood stoves burn longer and cooler than open fireplaces, so they produce more creosote per cord. In Monsey, where many homes heat with stoves from November through March, we recommend sweeping twice per burn season and inspecting the liner once a year. That’s more than a fireplace needs, but it’s what keeps third-degree glaze from forming in the smoke chamber. The repair bills from a neglected stove flue run far higher than a sweep ever will.
Saturated brick faces freezing and expanding. Monsey’s sustained below-freezing stretches, combined with driving northwest wind and rain, push water deep into the masonry. When it freezes, the brick face pops off. Original unlined or clay-lined chimneys are most vulnerable. If your chimney is flaking brick onto the lawn after a hard winter, the water has already been doing damage for years. We can patch localized spalling and waterproof to stop it advancing, and we’ll tell you if a rebuild is the smarter call.
What a Chimney Inspection Actually Looks Like in Monsey
Let’s walk through a real job, because it shows what we mean when we say we look before we quote. On a ranch home off Route 306 near the Monsey hamlet center, our tech found a 1960s single-flue masonry chimney now shared by a wood stove and a retrofitted gas insert. The added appliance was tied into an unlined flue with heavy third-degree creosote glaze in the smoke chamber. That’s a chimney fire built out of renovation decisions made two decades ago. We installed a DuraFlex stainless steel flue liner, repointed spalling brick at the chimney crown, and replaced failed step flashing. Then we advised the homeowner on burning only seasoned hardwood to keep first-degree creosote from returning.
The camera footage and a plain-English verdict, every time, no exceptions. If your chimney was modified during a kitchen addition or a heating system swap, the original flue may be doing work it was never designed for. A liner inspection costs a fraction of what a chimney fire costs, and it gives you a clear answer without anyone selling you anything.
