Frequently Asked Questions

A standard sweep and Level 1 inspection takes 45–75 minutes for most Yonkers homes. Heavily glazed systems in older homes near the Hudson River, where maritime moisture accelerates creosote buildup, may need 90–120 minutes with rotary chain equipment. We protect your floors with drop cloths, run HEPA vacuums, and leave no soot behind. You can stay home the whole time — many customers in Hastings-on-Hudson schedule during their work-from-home day.

We inspect the firebox, damper, and flue from top and bottom, then run brushes sized to your flue diameter to remove soot and creosote. We check for cracked mortar, deteriorated crown wash, and proper clearances to combustibles — critical in Yonkers' pre-war housing stock. After cleaning, we provide a written condition report with photos. If we find issues, we explain exactly what's urgent versus what can wait. No pressure, just facts from a team that's been doing this since 2013.

The National Fire Protection Association recommends annual inspection; cleaning frequency depends on use. Burning 2–3 fires weekly October through March means yearly sweeping. Occasional weekend users in Riverdale or Pelham can often go 18–24 months. The key factor is creosote buildup — Yonkers' cold, damp winters and many unseasoned firewood sellers mean our flues glaze faster than drier climates. We can check your buildup level and advise a personalized schedule.

You can run a brush from the hearth up, but you won't see what we see with our camera systems, and you can't safely access steep roofs common in Yonkers' hilly terrain. More importantly, DIY cleaning misses the critical inspection component — cracked flue tiles, missing mortar, and creosote glazing in the smoke chamber cause house fires we respond to every winter in Mount Vernon and Greenville. For safety and insurance documentation, hire a certified professional. We've been trained to spot what homeowners can't.

We service masonry fireplaces, factory-built metal chimneys, pellet stove vents, and gas fireplace inserts throughout Yonkers and surrounding areas. Many homes in Wykagyl and Bronxville have 1920s–1960s masonry systems with clay tile liners needing gentle handling. Newer constructions near Ridge Hill often have stainless steel factory-built units. We carry brushes and equipment for every common configuration in Westchester County — no "we'll come back with the right tools" delays.

For stainless steel relining, we install Olympia Chimney and Gelco products — both carry lifetime warranties and handle the freeze-thaw cycles brutal on Yonkers masonry. For resurfacing existing clay liners, we use HeatShield cerfractory foam, which seals cracks and restores smooth draft surfaces without full replacement. We don't push one brand for every job; we match the product to your chimney's condition, fuel type, and budget. Gary Murphy personally oversees every liner installation.

Yes — Famco stainless steel caps are our go-to for Yonkers homes needing animal and debris protection. Their multi-flue models work well on the large shared chimneys common in pre-war duplexes and apartment conversions near Getty Square. We also stock Gelco and Olympia caps for custom sizing. A proper cap prevents the water intrusion that destroys crowns and spalls brick faces every winter — it's the cheapest major protection you can add. Call (844) 660-6590 for cap sizing and pricing.

We're fully insured and bonded, carry New York State general liability coverage, and our technicians are CSIA-certified (Chimney Safety Institute of America). Yonkers doesn't require a specific chimney sweep license, but Westchester County mandates proper permitting for liner replacements and structural repairs — we handle all paperwork. Gary Murphy built this business on doing things by the book; our 4.7-star average across 1,142 reviews reflects that consistency. We carry certificates of insurance for co-op and condo buildings common in Bronxville and Tuckahoe.

Minor cleaning and cap installation don't require permits. Liner replacement, crown reconstruction, and any structural modification need permits through the City of Yonkers Building Department — we pull these as part of our service. Most towns in our service area, including Eastchester and Hastings-on-Hudson, have similar requirements. Unpermitted work can void insurance coverage and complicate home sales. We handle the paperwork and inspections so you don't worry about compliance.

We offer same-day and next-day availability for urgent situations — chimney fires, blocked flues, or carbon monoxide alarms — throughout Yonkers and neighboring areas. Standard cleanings typically book 3–7 days out October through February, our busiest season. We maintain expanded hours during peak demand because Yonkers winters don't wait. If you're in Wakefield, Woodlawn, or Pelham and smell smoke backing into your living space, call (844) 660-6590 immediately — we'll prioritize your safety.

Smoke pouring back into your home, visible flames in the flue, a strong gas odor from a fireplace insert, or a carbon monoxide detector alarm all require immediate professional response. A cracked crown or missing cap isn't an emergency but should be addressed before the next storm. We've responded to chimney fires in Mount Vernon and Greenville where homeowners delayed calling because they weren't sure — don't hesitate. If you're uncertain, call (844) 660-6590 and we'll triage over the phone.

We cover all Yonkers neighborhoods including Getty Square, Dunwoodie, Crestwood, Lawrence Park, Park Hill, Lincoln Park, Bryn Mawr, and Ludlow, plus adjacent areas in Bronxville, Tuckahoe, Mount Vernon, Eastchester, Woodlawn, Hastings-on-Hudson, Wakefield, Wykagyl, Riverdale, Pelham, and Greenville. Our technicians live locally — Gary Murphy is based in Yonkers — so we know the specific chimney types common in each area, from the pre-war masonry stacks in Park Hill to the newer prefab systems near Ridge Hill.

Every sweep and inspection comes with a 90-day workmanship guarantee — if smoke leaks, odors return, or you suspect we missed something, we'll return at no charge. Liner installations carry manufacturer lifetime warranties plus our 10-year installation guarantee. HeatShield resurfacing includes a 20-year warranty. We've honored these without argument since 2013 because our reputation in Yonkers matters more than any single job. Our 1,142 reviews show we stand behind our work.

We document everything with photos and video, explain urgency levels clearly, and never pressure for immediate add-on sales. Critical safety issues — blocked flues, severely cracked liners, or dangerous clearances — get flagged immediately with written documentation for your insurance or records. Maintenance items like minor crown cracks or cap replacement can usually wait until next season. Homeowners in Riverdale and Pelham particularly appreciate this transparency when managing co-op board approvals or escrow requirements.

Absolutely — a $200 sweep prevents $15,000+ in fire damage, structural repairs, or health costs from carbon monoxide exposure. Yonkers averages 40–60 chimney fires annually according to local fire department data, and nearly all involve uncleaned or uninspected systems. For homes with oil or gas heating, blocked flues force deadly gases back into living spaces — we've found bird nests and collapsed liner debris in Wykagyl and Eastchester that would have become tragedies. Annual service is inexpensive protection for your biggest investment. Call (844) 660-6590 to schedule — estimates are free.
