We’ve been working in Hollis for over 42 years. We know the brick Colonials along 199th Street, the semi-detached Tudors near Jamaica Avenue, and the two-family homes throughout Terrace Heights. These houses were built with chimneys designed for coal, converted to oil decades ago, and many never received proper clay-tile relining. That history lives in your flue. It affects how creosote builds, how acidic condensate eats mortar, and why a standard sweep without inspection can miss the real problem. Our Chimney Cleaning & Sweep team treats every Hollis chimney with that context in mind.
Why Hearthstone Chimney Co. of New York City Is Hollis’s Preferred Chimney Cleaning & Sweep Company
Hollis homeowners call us because we document what we find. Every Level 2 inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics, just what is wrong and what it costs to fix. We’ve earned our reputation in 11423 one chimney at a time.
Our response time to Hollis averages same-day or next-day for standard sweeps, and we keep our scheduling promises. We’ll be there when we say. That’s not a slogan - it’s how you run a company that plans to be in business thirty years from now.
Our technicians are background-checked, uniformed, and trained specifically on the multi-flue masonry chimneys that dominate Hollis housing stock. Most jobs are completed in a single visit. Our no-hassle upfront pricing means the number on the estimate is the number on the invoice. And every job is backed by our 90-Day Done Right Promise - in writing, no arguing.
We also understand the local regulatory landscape. Because Hollis sits just inside the NYC-Nassau County line, we’ve seen too many chimneys with work performed by Nassau-licensed contractors who didn’t know NYC DOB and FDNY requirements. That gap surfaces during home sales and insurance inspections. We fix those problems, and we document our work to NYC code from the start.
Our Chimney Cleaning & Sweep Services in Hollis
Level 1 Inspection
A Level 1 inspection is the visual examination required annually for chimneys in regular service. In Hollis, we perform these during every routine sweep, with special attention to the accessible portions of flues serving oil-fired boilers. We check for obstructions, creosote buildup, and basic structural integrity. For many Hollis homeowners, this is sufficient if the chimney has been well-maintained and no changes have been made to the appliance or liner.
Level 2 Inspection
Level 2 inspection is where our work in Hollis becomes essential. We run a camera through every flue, documenting the interior with photos you can see. This is non-negotiable for Hollis’s 1920s-1940s housing stock. Those original multi-flue chimneys, built for coal and converted to oil without proper relining, hide acidic condensate damage that visual inspection simply cannot catch. We recently serviced a two-family Colonial on 199th Street in Hollis where the shared chimney serving both oil-fired boilers had no liners; acidic condensate had eaten away the mortar in the upper flue, causing smoke spillage. We installed two HeatShield liners and performed an annual sweep to restore safe operation. Every Level 2 inspection ends with a plain-English verdict and written documentation.
Creosote Removal
Creosote accumulates differently in Hollis chimneys depending on fuel type and flue condition. Oil combustion produces sulfur-laden deposits that combine with moisture to form acidic sludge, particularly in oversized or unlined flues. Wood-burning fireplaces produce the familiar tar-like glaze. Our technicians match the removal method to the deposit type - rotary sweeping for glazed creosote, chemical treatment for heavy buildup, and mechanical brushing for standard accumulations. We use professional-grade materials from Olympia Chimney and Copperfield, never builder-grade substitutes that can damage older clay tile.
Soot Removal
Soot removal in Hollis requires attention to the two-family configurations common throughout the neighborhood. A single chimney structure frequently serves two separate boiler or furnace connections, meaning soot and debris from one flue can affect draft in another. We seal work areas, protect floors and furnishings, and use HEPA-contained vacuums to prevent any mess from spreading between units. For homeowners in Hollis’s attached and semi-detached housing, that containment matters - your neighbor’s air is separated by a wall, not a yard.
Annual Sweep
The annual sweep is the foundation of chimney safety in Hollis. Given the oil conversion history, freeze-thaw exposure, and age of local housing stock, we recommend every Hollis chimney be swept and inspected once per year - more frequently for heavy-use wood-burning fireplaces. Our annual sweep includes debris removal, flue brushing, damper check, and basic crown and cap assessment. We schedule these throughout the year, though late summer and early fall appointments fill fastest as homeowners prepare for heating season.

Trusted Brands We Service in Hollis
We stock professional-grade materials from Gelco, Olympia Chimney, and Copperfield - the brands we trust for Hollis’s demanding conditions. Gelco caps and screening withstand the freeze-thaw cycling that cracks lesser hardware. Olympia Chimney’s liner systems handle the acidic condensate produced by oil combustion in unlined flues. Copperfield’s professional tools let our technicians work efficiently in the tight flue configurations common in two-family Hollis homes. We don’t substitute builder-grade materials to save a few dollars. The job is either done right, or it’s not done.
Common Chimney Cleaning & Sweep Problems We See in Hollis Homes
- Acidic condensate damage in unlined oil flues. The majority of Hollis chimneys have oversized, unlined, or undersized flues that were never properly relined during the coal-to-oil conversion. Acidic condensate from oil combustion pools on smoke shelf ledges and eats away interior mortar joints and clay tile. We find this in nearly every 1920s-era home we inspect in 11423.
- Freeze-thaw spalling on exposed crowns. Hollis’s inland position in southeastern Queens means it lacks the mild temperature buffer of waterfront neighborhoods. Repeated freeze-thaw cycles crack mortar joints and spall brick facing on chimney crowns, opening paths for water intrusion. Annual inspection catches this before it reaches the flue.
- Unpermitted liner inserts from Nassau contractors. Because Hollis borders Nassau County, we regularly encounter liner installations performed by contractors licensed there but not compliant with NYC DOB and FDNY requirements. These gaps surface during home sales or insurance inspections, often requiring complete rework to code.
- Shared chimney conflicts in two-family configurations. A single masonry structure serving two separate heating appliances creates complex draft interactions. One tenant’s new high-efficiency boiler can alter draft sufficiently to cause backdrafting in the neighbor’s flue. Our Level 2 camera inspection identifies these interactions before they become safety hazards.
Pricing for Chimney Cleaning & Sweep in Hollis, NY
Chimney cleaning and sweep pricing in Hollis reflects the specific conditions we encounter in 1920s-1940s housing. A standard annual sweep with Level 1 inspection runs $189-$249 for a single-flue chimney, and $279-$349 for two-flue configurations common in Hollis two-family homes. Level 2 camera inspection, which we strongly recommend for first-time service or any chimney with oil conversion history, costs $425-$675 depending on flue count, accessibility, and whether rooftop rigging is required.
Heavy creosote removal requiring chemical treatment or rotary equipment adds $150-$300. Liner repair or installation, when needed, is quoted separately after inspection - we don’t guess. Our $89 Seasonal Tune-Up covers basic sweep and inspection for qualifying systems, and we offer $50 off any repair over $250. Seniors and veterans receive a permanent 5% discount. Every estimate is free, and the number we quote is the number on the invoice.

FAQs - Chimney Cleaning & Sweep in Hollis
Every Hollis chimney should be swept and inspected at least once annually, and any chimney with an unlined or questionably lined oil flue needs a Level 2 camera inspection every two to three years regardless of apparent condition. The acidic condensate produced by oil combustion in oversized coal-era flues causes damage that visual inspection cannot detect. Call (855) 950-3861 to schedule - we’ll tell you whether your flue history warrants more frequent attention.
You need a contractor licensed and insured to work in New York City, familiar with NYC DOB and FDNY requirements, not just Nassau County codes. We’ve corrected too many Hollis chimneys where Nassau-licensed work left documentation gaps, unpermitted liner inserts, or appliance connections that failed inspection during home sales. The few dollars saved upfront cost thousands to rework. We provide NYC-compliant documentation on every job.
Interior mortar and tile deterioration from acidic condensate in unlined or improperly lined flues. These chimneys were built for coal, converted to oil, and often never received proper clay-tile relining. The result is a flue that looks sound from the outside but has compromised interior surfaces that leak gases and accelerate creosote accumulation. A Level 2 camera inspection reveals what cannot be seen from the roof or fireplace.
Hollis’s inland position exposes chimneys to sharper temperature swings than waterfront Queens neighborhoods, with repeated crossings of the 32°F threshold that crack mortar joints and spall brick facing on exposed crowns. Water enters hairline cracks, freezes, expands, and widens them progressively. Annual inspection catches crown and mortar damage before it compromises flue integrity. We repair crowns with professional-grade materials rated for this exact cycling.
A complete internal camera survey of every flue, photos you can see, assessment of liner condition and compliance with NYC Mechanical Code, evaluation of shared-flue draft interactions, and a written plain-English verdict with repair priorities. For Hollis two-family homes with single chimneys serving two appliances, we specifically document whether each flue is independently lined and whether draft conditions in one unit affect the other. Call (855) 950-3861 to book - estimates are free.
