Frequently Asked Questions

We lay protective floor coverings, seal the fireplace opening with a vacuum attachment, and run rotary brushes up the flue from the firebox or down from the roof depending on your system. Soot and creosote are contained and removed. The sweep takes 45 minutes to 90 minutes for most Flushing homes. Afterward, we walk you through what we found and leave the work area cleaner than we found it.

The National Fire Protection Association recommends annual inspection, with sweeping as needed based on creosote buildup. In Flushing's climate, where heating systems run hard from November through March, most wood-burning chimneys need sweeping every year. Gas and oil flues typically need less frequent cleaning but still require annual inspection for blockages, liner deterioration, and venting integrity. If you burn more than three cords of wood per season, consider mid-season inspection.

Most standard sweeps in Flushing, Jackson Heights, and Rego Park take 45 minutes to 90 minutes from arrival to cleanup. Level-2 inspections with camera work run 90 minutes to two hours. We don't rush. The tradesman who trained us said the flue doesn't care about your schedule, and we've found that to be true. We'll be there when we say, and we'll stay until it's done right.

No. We use industrial HEPA vacuums and sealed containment for every job in Queens, from Astoria to Middle Village. The fireplace is blocked off before brushing begins, and our tools are designed to capture debris at the source. In twelve years of service, we've learned that a clean jobsite is part of a square deal.

Remove ashes from the firebox if there's more than an inch, clear the mantel of fragile items, and make sure we have access to the fireplace and an electrical outlet. Don't light a fire for 24 hours before we arrive - a hot flue can't be swept safely. If we need roof access, we'll discuss that when we book. No other preparation is needed.

For stainless steel relining, we often specify DuraFlex or Olympia Chimney products, both of which carry proper UL listings and perform well in our northeast climate. For cast-in-place liner restoration, we've had consistent results with HeatShield cerfractory systems. We don't push one brand for every job - the right liner depends on your fuel type, flue dimensions, and whether the chimney serves a fireplace, furnace, or both. Every recommendation comes with photos showing why it's needed.

Yes. Gelco makes a reliable line of stainless steel and copper caps that hold up well against Flushing's coastal weather cycles - the salt air off the Long Island Sound accelerates corrosion on cheaper galvanized products. We measure on site and fit caps that actually cover the full flue opening, not the one-size-fits-most versions that let rain in around the edges.

We source mortar mixes to match the age and composition of Queens masonry, from the soft lime-based mortars of pre-war Flushing bungalows to harder Portland cement blends in newer construction. Color matching isn't perfect on century-old brick, but we get close enough that you won't notice from the sidewalk. The hearthstone is the stone the whole home gathered around, and we treat it that way.

Every pro working under our name is required to hold the license and insurance New York requires, and we prioritize CSIA-certified sweeps for field work. Certification matters because chimney work sits at the intersection of fire safety, carbon monoxide venting, and structural integrity. We document every inspection with photos and a written report - that's part of our K.E.Y.S. values code, specifically "Krafted right" and "Standing behind it."

We carry general liability and workers compensation coverage as required for residential chimney work in New York. We're happy to provide a certificate of insurance for your records, particularly for real estate transactions or co-op board requirements common in buildings from Rego Park to Elmhurst. Just ask when you call (516) 206-6672.

Structural chimney repairs, liner replacements, and new appliance connections in Flushing fall under NYC Department of Buildings permitting requirements. We handle permit applications as part of the project scope when they're required. For standard sweeping and level-1 inspection, no permit is needed. We'll tell you upfront if your job triggers permitting, what it costs, and how long it takes - no surprises on the bill.

A chimney fire - marked by loud cracking, dense smoke, or a roaring sound in the flue - requires immediate evacuation and a 911 call. Carbon monoxide alarms, sudden downdrafts filling the house with smoke, or visible structural damage after a storm also need prompt professional assessment. Our phone is answered 24/7, and we'll schedule urgent inspections as quickly as possible for situations that don't require emergency services.

Yes, and we recommend it. A level-2 inspection with internal camera is standard for real estate transactions in Flushing, Bayside, and Whitestone. We provide a dated report with photos that satisfies most co-op boards and mortgage underwriters. Schedule early in your inspection period - if we find liner damage or missing mortar, you'll want time to negotiate repairs or get second opinions.

Our standard service area includes Flushing, Astoria, Bayside, Whitestone, Elmhurst, East Harlem, Jackson Heights, Middle Village, College Point, Throgs Neck, Rego Park, and Woodside. We've swept chimneys in pre-war apartments near Astoria Boulevard and in detached homes off the Cross Island Parkway. Each neighborhood has its own chimney quirks - the tight flues in 1920s Elmhurst duplexes, the salt-air corrosion in College Point - and we adjust our approach accordingly.

Our chimney sweep and inspection work is covered by The Keystone Standard: 90 days, in writing, no arguing. If we swept it and you discover a blockage or performance issue we should have caught, we come back. The guarantee covers our workmanship, not new damage from weather, animal intrusion, or changes in how you use the fireplace. We stand behind it because we document everything - photos, readings, observations - so there's no dispute about what was true on the day of service.

Stainless steel liners from DuraFlex and Olympia Chimney carry manufacturer warranties ranging from lifetime to limited lifetime, depending on the product line and fuel type. Our installation workmanship is covered separately under The Keystone Standard. We register the manufacturer's warranty on your behalf and provide you with the documentation. Keep it with your home records - a properly installed and maintained liner should outlast your mortgage.

Call us. The "Y" in our K.E.Y.S. code stands for "Your home first" - we work in your house the way we'd work in our mother's. If something's not right, we don't hide behind paperwork or phone trees. Russell Haines reviews every callback personally, and we'll make it square. In twelve years, we've learned that a company that plans to be in Flushing in thirty years doesn't quibble over a job that wasn't done right.

We don't promise same-day dispatch - a proper sweep can't be rushed, and we'd rather book you correctly than squeeze you in poorly. During peak season (September through November in Queens), we recommend calling two to three weeks ahead. For urgent safety concerns, we do our best to accommodate quickly. The phone is answered 24/7, and our live coordinator will find you the earliest slot that allows us to do the job properly.

Every inspection includes a written report with dated photos, delivered by email or printed copy before we leave. Real estate transactions in Flushing and Bayside often require this documentation for co-op boards or insurance underwriters. We keep records on file for at least three years, so if you misplace your report, we can resend it. No charge for that - it's part of the square deal.
