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.

AfterChimney Cleaning Services in Midwood, NY
Chimney cleaning in Midwood typically costs between $199 and $349 for a standard sweep with Level-1 inspection, and most appointments are completed in a single visit. For the older brick homes that define this Brooklyn neighborhood, we strongly recommend adding a Level-2 camera inspection, which runs $289-$449 and includes photos you can see plus a plain-English verdict on whether your flue is safe for another season. Call us at (516) 613-3035 - a live person answers 24 hours a day, and we’ll schedule you at a time that actually works.
We’ve been working on Midwood chimneys long enough to know what waits inside them. The detached Colonials along Avenue J, the Tudors tucked behind Ocean Parkway, the cape-style homes on East 16th Street - they all share the same lineage. Built in the 1920s through 1940s with full masonry chimneys sized for coal furnaces, most were never properly adapted for the gas boilers and fireplaces they vent today. That mismatch between an oversized flue and a modern appliance is not a minor quirk. It’s the reason we carry DuraFlex liner stock on every truck, and it’s why we open every job with a camera before we commit to a scope of work.
Our scheduling runs from our New York City office, but the crews serving Midwood live and work in Brooklyn. They know the local permit environment, the NYC DOB liner-sizing rules that trip up homeowners during resale inspections, and the particular way salt-laden moisture from the nearby Atlantic coast works into mortar joints that haven’t been tuckpointed in four decades. When you call, you get a human who understands the neighborhood, not a call center reading from a script.

Why Midwood Homeowners Choose Hearthstone Chimney Co.
After 42 years in this business, we’ve learned that the homeowners who call us in Midwood aren’t looking for the cheapest sweep in Brooklyn. They’re looking for someone who will tell them the truth about a chimney they’ve ignored for fifteen years, document what they find, and stand behind the repair without making them chase down a warranty.
Our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit. They carry professional-grade materials from HeatShield, Gelco, and Copperfield - no builder-grade substitutes that fail in three seasons. Every inspection ends with photos and a written verdict. If we recommend a liner, you’ll see the flue damage that justifies it. If the chimney can safely wait another year, we’ll say so plainly. The 90-Day Done Right Promise covers every job in writing: if it’s not right, we make it right, no paperwork and no arguing.
We serve homeowners throughout the neighborhood, from the quiet blocks near Brooklyn College to the tree-lined streets of Fiske Terrace. Whether you’re off Coney Island Avenue or closer to the historic district around Avenue L, our response time is consistent - typically within a few days for non-urgent sweeps, faster when creosote buildup or structural damage creates a genuine safety concern.
Midwood residents tend to stay in their homes for decades. We plan to be here for decades too. That changes how you treat every job.
Chimney Cleaning Services We Offer in Midwood
Chimney Cleaning & Sweep
Our standard sweep removes soot, creosote, and debris from the flue, smoke chamber, and firebox, followed by a Level-1 visual inspection. For Midwood’s older chimneys, we often find glazed creosote - the hard, tar-like buildup that forms when fires don’t burn hot enough or long enough to fully heat the flue, common in homes that use fireplaces only occasionally during holiday weeks. Learn more about our Chimney Cleaning & Sweep in Midwood.
Chimney Repair
Freeze-thaw damage from Brooklyn’s coastal winters attacks mortar joints and brick faces that haven’t been maintained since the Reagan administration. We tuckpoint, rebuild crowns, and replace damaged brick with matching materials - documented with before-and-after photos, priced upfront, and backed by the 90-Day Done Right Promise. Learn more about our Chimney Repair in Midwood.
Fireplace Services
Gas insert installations, firebox refractory panel replacement, and damper repair for the working fireplaces in Midwood’s pre-war homes. We size every installation to the existing flue or specify relining when the chimney was built for a coal furnace and now needs to vent a sealed gas unit safely. Learn more about our Fireplace Services in Midwood.
Chimney Cap & Crown Installation
A proper cap keeps rain, squirrels, and wind-blown debris out of your flue. We fabricate and install crowns that shed water correctly - critical in Midwood, where salt-laden moisture accelerates deterioration - using Gelco and Copperfield components sized to your chimney’s exact dimensions.
Chimney Liner & Rebuild
This is the defining job in Midwood. On East 17th Street and blocks like it, we routinely find 12×12 unlined flues venting modern gas boilers - a configuration NYC DOB guidelines prohibit because it risks carbon monoxide spillage into living spaces. We install DuraFlex stainless steel liners and HeatShield cerfractory flue sealant systems, sized precisely to your appliance’s BTU output and documented with photos for your records.
Neighborhoods We Serve in Midwood
Our crews work across the full Midwood grid, with particular familiarity in these areas:
- Fiske Terrace - the detached brick homes near the Q train, many with original 1930s chimneys never adapted for gas
- Avenue J corridor - Colonials and Tudors with full-height masonry that demands careful ladder staging on narrow lots
- Brooklyn College vicinity - mixed housing stock where rental conversions often skipped proper chimney maintenance
- Ocean Parkway east - cape-style homes with steep-pitched roofs and chimneys exposed to full coastal wind load
- East 16th to East 18th Streets - dense concentrations of pre-war brick where unlined gas flues are epidemic
Most appointments are scheduled within a few days; we coordinate dispatch from our New York City office to keep routes efficient and arrival times reliable.
Why Midwood’s Climate & Housing Affect Chimney Cleaning
Midwood sits in a narrow Brooklyn corridor between the Atlantic coast and Jamaica Bay, and that geography matters more than most homeowners realize. Salt-laden moisture rides in on easterly winds, penetrates hairline cracks in century-old mortar, and expands through repeated winter freeze-thaw cycles. A chimney that looked sound in October can show spalled brick and eroded joints by March. We’ve opened clean-out doors on East 16th Street chimneys and found the interior face of the flue crumbling into the soot - damage the homeowner never saw because it was hidden behind a boiler and a water heater.
The housing stock compounds the problem. These brick detached and semi-detached homes were built with clay tile flues designed for coal combustion at temperatures modern gas appliances never reach. When a 150,000 BTU gas boiler vents into a flue sized for a coal furnace, the exhaust cools too quickly, condenses on flue walls, and combines with sulfur traces to form acidic moisture that attacks mortar from the inside. Meanwhile, the low, intermittent firing typical of modern heating systems never generates enough sustained heat to drive proper draft. The result is a chimney that “works” until it doesn’t - often discovered during a home inspection, or worse, when a CO detector sounds at 2 a.m.
For fireplaces, the pattern reverses. Midwood homeowners who burn wood only during Christmas week or the occasional February cold snap tend to build small, short fires in cold flues. That produces the glazed creosote that standard wire brushes won’t remove. We carry rotary cleaning systems and chemical treatments for exactly this scenario, and we flag it during inspection so you understand why the sweep took longer than expected.

FAQs About Chimney Cleaning in Midwood
A standard chimney sweep with Level-1 inspection runs $199 to $349 in Midwood, with most homeowners paying near the middle of that range. Older homes with glazed creosote or difficult access may fall at the higher end. Call (516) 613-3035 for an exact quote - estimates are free.
The National Fire Protection Association recommends annual inspection for all chimneys, with sweeping as needed based on creosote accumulation. In Midwood’s climate, we find that wood-burning fireplaces used even occasionally need sweeping every 1-2 years, while gas-venting chimneys should be inspected annually for liner integrity and draft performance. Call (516) 613-3035 to schedule - we’ll tell you honestly if yours can wait.
Only if your current flue is damaged, improperly sized, or unlined - and we’ll prove it with camera photos before recommending anything. In Midwood, we frequently find unlined 12×12 flues venting gas boilers, which violates NYC DOB guidelines and creates real carbon monoxide risk. But we’ve also inspected chimneys with intact clay tile that will serve another decade. The photos decide, not a sales pitch. Call (516) 613-3035 if you’ve been told you need a liner and want a documented second opinion.
Skipped maintenance leads to three predictable problems: creosote buildup that can ignite into a chimney fire, blocked or deteriorated flues that vent carbon monoxide into living spaces, and moisture damage that turns a $300 tuckpointing job into a $4,000 rebuild. In Midwood’s older housing stock, the risk is elevated because so many chimneys were never properly adapted for modern appliances. The good news is that all three are preventable with regular inspection. Call (516) 613-3035 to get back on schedule.
Yes. We’ve worked on Midwood’s narrow lots for decades and carry ladders and staging equipment sized for tight side yards. The brick semi-detached homes along East 17th Street and similar blocks are routine for our crews. We protect your property, your neighbor’s property, and your landscaping - documented with photos, priced upfront, done in a single visit. Call (516) 613-3035 to schedule.

What Midwood Customers Say
"The crown was cracked and taking water. He repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
- Rashad Jackson"The cap keeps the birds out now, which after two springs of scratching noises above the bedroom is worth every penny."
- Nisha Gupta"Swept it, capped it, and fitted a proper damper. The downdraft smell we had lived with every summer is gone."
