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 Liner & Rebuild Services in New Hempstead
Stainless Steel Liner Installation
We install DuraFlex and Olympia Chimney stainless steel liners throughout New Hempstead for oil, gas, and solid-fuel systems. These liners handle the thermal cycling that cracked your original clay tiles, and they flex through the offset flues common in expanded colonials. A stainless installation in New Hempstead typically runs $2,800-$4,200 for a standard single-flue chimney, including the connector, top plate, and rain cap. We size every liner to the appliance - oversized liners draft poorly and collect creosote; undersized ones overheat and fail early.
Flexible Liner Solutions
For chimneys with offsets or bends - the kind we find in New Hempstead homes where a rear addition shifted the original flue path - flexible liners navigate corners rigid pipe cannot. Our crew pulls the liner through from the top, seals the joints with high-temp sealant, and pressure-tests before we call the job complete. Flexible installations run $3,200-$4,800 depending on length and access. We pulled up to a split-level off Route 45 in New Hempstead where the homeowner had added a rear family room and rerouted the original flue around a new beam. A camera sweep showed the old clay tile had cracked at the offset; we ran a DuraFlex stainless liner through the reconfigured path, reset the damper, and completed a New Hempstead Chimney Cap & Crown repair before the next nor’easter rolled through the Ramapo valley.
Liner Replacement
When your existing liner is spalling, cracked, or separated at the joints - conditions we find regularly in New Hempstead’s 40-55-year-old masonry - replacement is the only safe option. We remove the damaged material, inspect the surrounding brick and mortar with our camera, and install a new liner sized to your heating appliance. Liner replacement in New Hempstead ranges from $3,500-$5,500. If the smoke chamber or firebox needs parging, we’ll show you the photos and quote it upfront. Nothing is added after the fact.
Partial Chimney Rebuild
Not every failing chimney needs to come down to the roofline. A partial rebuild addresses the stack above the roof - the crown, the upper courses of brick, and the flue termination - while preserving sound masonry below. In New Hempstead, where ridge-line homes take the brunt of northwest winter winds, we’ve found that upper-stack deterioration often outpaces the rest of the chimney. Partial rebuilds run $4,500-$6,500 and typically resolve the water infiltration and draft problems that damage liners from the outside in. Our Chimney Liner & Rebuild crew will tell you honestly whether a partial rebuild is sufficient or whether the full stack needs attention.

These are not builder-grade substitutes - they’re the materials factory-certified technicians specify.

Common Chimney Liner & Rebuild Problems We See in New Hempstead Homes
- Shared or adjacent flues in attached properties. New Hempstead’s dense housing means neighboring appliances sometimes exhaust into the same stack or one directly beside it. A failing liner in your unit can let your neighbor’s furnace fumes migrate through gaps in the masonry - or vice versa. We map the flue path with our camera before any repair begins.
- Downdraft on ridge-line lots. Homes on the village’s higher ground, especially near the Ramapo escarpment, catch northwest winds that push combustion byproducts back down the stack. The symptom is smoke or odor in your living room; the cause is often a liner too deteriorated to maintain adequate draft pressure. A properly sized stainless liner with a correctly terminated cap usually solves it.
- Misaligned liner joints from colonial additions. The 1970s-80s colonials expanded in the 1990s or 2000s to accommodate larger families frequently have flue offsets that left original liner joints misaligned. Spalling mortar hides in these gaps until a Level-2 inspection exposes the separation. We’ve found three-foot voids where the liner should be continuous.
- Undocumented service history. Because New Hempstead properties often transfer through informal arrangements rather than standard sales with disclosure, many chimneys arrive with zero documented sweeps. We regularly find three or more seasons of creosote buildup in systems the current owner assumed had been maintained. That accumulation accelerates liner deterioration and hides cracks from casual inspection.

What moves the number? Access - steep roofs or tight side yards add labor. The condition of the existing masonry - sound brick saves money, spalled courses don’t. And the appliance type: solid-fuel systems need higher-grade liners than gas inserts. We price every job after inspection, not before. The estimate is free, and the number we give you is the number on the invoice. Ask about our $50 off any repair over $250, or the permanent 5% senior and veteran discount.

FAQs - Chimney Liner & Rebuild in New Hempstead
Yes, if either liner is cracked or the masonry between flues has deteriorated, combustion gases can migrate through gaps into your firebox. We see this in New Hempstead’s attached properties more than in surrounding towns because of the village’s dense housing pattern. A Level-2 camera inspection maps every flue and identifies cross-connection points before we quote Chimney Repair in New Hempstead. Call (845) 599-0930 - we’ll inspect both sides and show you exactly where the separation has failed.
All our liner inspections and rebuilds in New Hempstead are scheduled Sunday through Thursday afternoon, with no crew arrivals on Friday after sundown or anytime Saturday. We’ve maintained this rhythm for years - it’s simply how we operate in this community. Bookings during the High Holidays and other major observances also adjust to the calendar. Call anytime; our live dispatch will find a slot that respects your household’s schedule.
Often it does not, because the addition rerouted the flue path and left the original clay tile cracked at the offset or misaligned at the joints. We’ve found this exact condition in dozens of expanded New Hempstead homes - the fireplace looks fine, but the camera reveals a three-foot gap where exhaust leaks into the wall cavity. We won’t know until we look. The $250-$350 inspection is the cheapest insurance against a concealed hazard.
A partial rebuild addresses only the stack above the roofline - crown, upper brick courses, and flue termination - while preserving sound masonry below. A full rebuild removes everything from the roofline up, and sometimes the breast below, when the entire structure is compromised. In New Hempstead’s 40-55-year-old housing stock, partial rebuilds handle roughly 60% of what we see; we only recommend full rebuilds when the camera shows systemic mortar failure or shifting foundation. We’ll show you the photos and explain which category you’re in - no guesswork, no pressure.
You’re likely experiencing downdraft, common on New Hempstead’s ridge-line lots where northwest winter winds hit the stack directly. A deteriorated liner can’t maintain the negative pressure that draws smoke upward, so the wind wins. The fix is usually a properly sized stainless liner with a code-compliant termination cap, not a magic draft inducer or our Fireplace Services in New Hempstead rebuilding the whole structure. We’ll confirm the diagnosis with a smoke-puff test during inspection. Call (845) 599-0930 for a camera evaluation - estimates are free.
