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 Hearthstone Chimney Co. Is New Hempstead’s Preferred Chimney Repair Company
New Hempstead homeowners call us because we understand what other companies miss. The village’s dense Orthodox Jewish community means chimneys here carry heavier winter loads than typical Rockland County homes - large families, frequent Shabbat and holiday use, and extended heating seasons that push masonry to its limits. We’ve repaired chimneys off Summit Road, along New Hempstead Road, and throughout the village’s ridgeline neighborhoods where downdraft conditions accelerate spalling and creosote damage.
Our reputation here is built on documentation. Every inspection ends with photos you can see and a plain-English verdict. No surprises on the bill - the number on the estimate is the number on the invoice. Our 90-Day Done Right Promise covers every repair in writing with no arguing. If it’s not right, we come back.
Background-checked, uniformed technicians complete most jobs in a single visit. And when we say we’ll be there, we’ll be there.
Our Chimney Repair Services in New Hempstead
Mortar Repointing
The 40-55 year old mortar in New Hempstead’s colonials and split-levels has endured decades of freeze-thaw cycling at the foot of the Ramapo highlands. When joints crumble, water penetrates the wall cavity and accelerates deterioration from the inside out. We grind out failed mortar to proper depth and repoint with color-matched, professional-grade mortar rated for our climate. Most repointing jobs on a standard New Hempstead chimney run $650-$1,200 and finish in one day.

Spalling Brick Repair
Spalling - bricks flaking and crumbling at the surface - is common on New Hempstead’s ridgeline homes where winter nor’easters drive moisture into the masonry, then freeze it. We remove damaged brick, assess the underlying structure with our camera system, and rebuild with matching units. Severe spalling often signals crown failure or flashing gaps above, so we inspect the full system before quoting. Typical spalling repair in New Hempstead: $800-$1,800.

Chimney Waterproofing
Rockland County’s wet springs and heavy winter precipitation saturate porous brick. We apply breathable, silane-based waterproofing agents from professional-grade suppliers that allow vapor to escape while blocking liquid water. For New Hempstead homes with shared flue configurations or non-original offsets from family expansions, waterproofing is preventive maintenance that protects masonry where internal access is limited. Expect $450-$850 for application on a standard chimney.

Flashing Repair
Flashing is where most New Hempstead chimneys leak first. The village’s original 1970s-80s construction often used step flashing that has separated from the roof plane after decades of thermal movement, or counter-flashing that was never properly integrated with the masonry. We fabricate and install new flashing with proper overlap and sealant, using materials from Copperfield and Famco. Because many New Hempstead homes have been expanded with rooflines that now abut the original chimney, flashing repair here often requires custom work. Typical range: $550-$1,100.

Chimney Rebuilding
When spalling, settling, or freeze-thaw damage has compromised structural integrity, partial or full rebuild becomes necessary. We’ve rebuilt chimneys on expanded New Hempstead properties where the original structure could no longer safely support added flue loads. Rebuilds range from $2,200 for a partial stack to $6,500+ for full reconstruction with new liner. Every rebuild includes camera inspection of the remaining structure and documentation of the work.

Tuckpointing
For chimneys where mortar deterioration is cosmetic or early-stage, tuckpointing addresses the visible joints without full repointing. We match existing mortar color and profile to preserve the home’s appearance while stopping water intrusion. Tuckpointing on New Hempstead’s older colonials typically runs $400-$750.

For New Hempstead customers, this means faster turnaround because we don’t wait on special orders for standard components.

Our technicians are trained on each manufacturer’s installation requirements, and we document every repair with photos and a written verdict you can reference.
Common Chimney Repair Problems We See in New Hempstead Homes
- Shared or adjacent flues in expanded properties. Because New Hempstead flues were built for one appliance and many homes have since added boilers, wood stoves, or a second fireplace without cutting a new flue, a single shared stack can carry two households’ combustion byproducts. A repair on one side of the masonry can be compromised by a neighbor’s appliance venting into the same run. We never trust an assumed “last cleaning” date when scoping shared-flue work.
- Non-original flue offsets hidden behind remodel walls. Significant room additions common in New Hempstead’s Orthodox community have altered original flue paths, making liner condition unpredictable until camera inspection. We’ve found offsets behind newer interior walls that redirected smoke into stud cavities.
- Ridgeline downdraft accelerating crown and brick damage. Homes on New Hempstead’s higher lots catch northwest winds channeling through the Ramapo valley. Downdraft pushes combustion byproducts back into the flue rather than drawing them out, creating third-degree creosote and spalling brick at the crown where freeze-thaw cycles concentrate.
- Undocumented service histories from informal home transfers. Because New Hempstead properties frequently transfer through rabbi-brokered arrangements rather than standard MLS sales, chimney maintenance records are often completely absent. Technicians regularly find three or more seasons of unswept creosote buildup in fireplaces where the current owner assumed the previous family had kept up maintenance.

FAQs - Chimney Repair in New Hempstead
Yes - we regularly repair offset flues in expanded New Hempstead homes without disturbing interior finishes. We run a Level-2 camera inspection first to map the actual flue path, then determine whether relining, HeatShield resurfacing, or targeted masonry repair will restore safe venting. On that Summit Road job, the offset was hidden behind a newer interior wall; we confirmed it with camera, installed a HeatShield liner, and replaced the rusted damper - no drywall removed. Call (845) 599-0930 to schedule camera inspection.
We schedule all New Hempstead work to respect Shabbat from Friday sundown through Saturday night, and we maintain a current holiday calendar to avoid conflicts with Pesach, Sukkot, and other observances. Our live-answer phone staff notes these constraints when booking, and our technicians plan accordingly. This is standard practice for us, not an exception - we’ve served New Hempstead’s Orthodox community for decades and understand the rhythm of the village’s calendar.
The only reliable way to confirm shared flue configuration is camera inspection combined with a smoke test. We insert a camera to document all flue openings and their connections, then introduce non-toxic smoke to trace airflow paths. In New Hempstead’s attached and expanded properties, we’ve found boilers, water heaters, and second fireplaces venting into single stacks that were never designed for multiple appliances. This is a genuine carbon monoxide and creosote cross-contamination risk. If your home shares walls or was expanded from an original structure, call (845) 599-0930 for inspection.
Bad enough that we treat every undocumented chimney as unswept until proven otherwise. In New Hempstead’s informally transferred properties, we’ve found three or more seasons of glazed creosote, deteriorated liners, and blocked flues that the current owner had no idea existed. The previous family may have maintained it. They may not have. Without records, we assume nothing. Camera inspection takes 45 minutes and gives you photos you can see with a plain-English verdict. Estimates are free.
Most spalling crowns with early-stage damage can be repaired with CrownCoat or similar professional-grade resurfacing products, combined with downdraft mitigation such as a properly sized cap or flue extender. If the crown has cracked through to the flue liner or the brick below is saturated and failing, partial rebuild becomes necessary. New Hempstead’s ridgeline exposure to Ramapo winds makes crown condition especially critical - a compromised crown lets water into the stack, freeze-thaw does the rest. We camera-inspect, show you the photos, and tell you honestly whether repair or rebuild is the right call. Call (845) 599-0930 for a free estimate.
