Do I need a permit for relining in Hempstead?

In New York, permits are issued locally by the municipal or county building department, not by a state agency. Relining a flue as part of an appliance installation typically requires a permit, while routine sweeping and inspection generally do not. Call your local building department before work begins, since thresholds vary between jurisdictions.

Is there a state chimney licence I should check?

New York does not issue a statewide licence for chimney sweeping, inspection or masonry repair. Nassau County runs its own home improvement contractor licensing programme, so verify current requirements with the county consumer affairs or licensing office. You can confirm code questions with your local building department or the NYS Division of Building Standards and Codes.

What code applies to this work?

Chimney work in New York is evaluated against the New York State Uniform Fire Prevention and Building Code, which is based on the International Code Council family of codes with state amendments. Solid-fuel appliance and chimney installations are also commonly evaluated against NFPA 211 and the appliance manufacturer's listed instructions.

I'm converting my boiler to gas. Does the chimney still need lining?

Converting to gas without relining leaves acidic condensate attacking the masonry. Many older Hempstead homes vent oil or gas boilers into unlined masonry chimneys, which is exactly the situation where this comes up. Have the flue inspected and matched to the new appliance.

Liner damaged in Hempstead, NY

Someone has looked up your flue and told you the liner is cracked. That liner is the layer that keeps heat and combustion gases inside the chimney and away from the wood framing of your house. When clay tiles crack or a metal liner fails, heat and carbon monoxide can reach the structure. Until the flue has been checked and verified, do not use the fireplace or the appliance that vents into it.

Chimneys in Hempstead take a beating. Winters here bring repeated freeze-thaw cycles, and a flue that has absorbed moisture breaks down faster each time the temperature swings. The village sits about five miles inland from the South Shore bays, so salt-laden air and nor'easter winds still reach it and work on caps and flashing. Much of the housing stock predates 1960, and across Nassau County older homes often still run oil or gas boilers vented into unlined or clay-tile masonry chimneys. Humid summers keep unused flues damp, which does the masonry no favours either.

While you wait — please don't

Stop using the fireplace or appliance. A damaged liner lets heat and carbon monoxide pass into the structure of the house, so the appliance should stay off until the flue is verified.
If anyone feels sick or a CO alarm sounds, get outside. Headache, dizziness, nausea or a sounding carbon monoxide alarm means everyone leaves the house and you call 911 from outside.
Do not use the flue again after a chimney fire. Clay tiles crack in a chimney fire, and the flue must be inspected before it is used again.
Do not light the fire to test it. Burning to see whether it draws properly puts heat straight against the damage you were told about.
Do not run a gas conversion through an unlined flue. Converting to gas without relining leaves acidic condensate attacking the masonry from the inside.

What the technician does

Camera inspection firstThe technician runs a camera the full length of the flue before quoting anything. Ask to see the footage and ask for the reasoning in writing.
The appliance and flue are matchedSize, material and termination all have to suit what is actually venting into the chimney, whether that is an open fireplace, a wood stove or an older boiler.
A stainless steel liner sized to the applianceIn most cases the fix is a stainless liner cut to the right diameter for the appliance, insulated where that is required.
Cast-in-place lining where appropriateSome chimneys suit a cast-in-place lining instead, particularly older masonry where the existing tiles have broken up.
Cap and crown addressed at the same timeThere is no sense lining a flue and leaving water pouring in at the top, so the cap and crown are dealt with in the same visit.
Price before workThe technician inspects, gives you the price, and you approve it before anything starts. The estimate is free.

Why this happens in Hempstead, NY

Hempstead's older wood-frame Colonials, Capes and Tudors, along with the two-family homes and apartment buildings near downtown and the Hofstra University area, often have masonry chimneys serving fireplaces and older boilers. Those chimneys are frequently unlined or lined with clay tile. That is fine until the tile cracks. New York has some of the oldest housing stock in the country, and relining is one of the most common repairs on it.

Timing matters here. Demand across the area spikes in early spring after winter freeze-thaw damage, then again in late summer and fall as people prepare for hurricane season and heating-system startup. Tropical storms and hurricanes, Irene in 2011 and Sandy in 2012, plus winter wind-driven rain, are the main severe-weather threats in Hempstead, and mature street trees mean downed-limb damage to chimney crowns is a recurring call. If your flue is already compromised, the heating season is not the time to find out.
