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.
Fast, Reliable Chimney Liner & Rebuild Across Hempstead
Chimney liner and rebuild work in Hempstead typically runs $1,800-$4,200 for a stainless steel liner installation and $3,500-$9,000 for a partial to full rebuild, with most jobs completed in one to two days. The number that matters more than the price is whether the liner is sized right for the appliances venting through it, and whether the mortar joints holding the chimney together will survive another South Shore winter. Wendell Pike and his crew at Top Hat Chimney have been inside more Hempstead flues than we can count, and we’ll show you the camera footage before we recommend spending a dollar. Call (516) 963-1068 for an honest look at what your chimney actually needs.
Why Top Hat Chimney Is Hempstead’s Preferred Chimney Liner & Rebuild Company
Founded in 1999, Top Hat Chimney is the locally owned alternative to the national outfits that quote one price on the phone and a different one at the door. Wendell puts his name and license number on every job, and the 90-Day Done Right Promise is stamped in writing: if the work isn’t right, one call brings the crew back at no charge. Hempstead homeowners ask around. They talk to neighbors on Nichols Court, on Linden Avenue, over by Kennedy Park. What they hear is that Top Hat answers the phone with a live person, gives a real arrival window, and the number quoted before a tool comes off the truck is the number on the invoice.
We know Hempstead’s housing stock because we’ve worked on it for decades. Brick and stucco Cape Cods off Front Street, colonials near Hofstra, semi-detached two-families along Peninsula Boulevard. Most were built between 1925 and 1960, and nearly all of them have original masonry chimneys that predate modern liner standards. That’s not a general observation. That’s what we see standing on Hempstead roofs, week after week. If you’re within Hempstead’s borders, we’re close by, and we’ll give you a straight answer on the phone before we ever schedule the visit.
Key takeaways:
- Owner-operated since 1999; Wendell Pike stands behind every job with a written 90-Day Done Right Promise.
- A live person answers 24/7, not a call center, and it may well be Wendell himself.
- Upfront pricing before work begins; no surprises at the door.
- We show you the camera footage and give a plain-English verdict, every time.
Our Chimney Liner & Rebuild Services in Hempstead
Most Hempstead homes were built with single-wythe or double-wythe brick chimneys that never had clay tile liners at all, or had liners that cracked decades ago. The work we do falls into a few clear categories, and we’ll tell you plainly which one applies to your chimney, or whether you can safely wait.
Stainless Steel Liner
For a Hempstead home converting from oil to gas, a stainless steel liner is usually the right answer. The lower-temperature exhaust from a gas boiler or furnace condenses inside an oversized, unlined flue and creates acidic byproduct that eats mortar from the inside out. We install properly sized stainless liners from DuraFlex and Olympia Chimney that handle the corrosive exhaust and bring the flue up to current code. This is the single most common job we do in Hempstead, because the oil-to-gas conversion wave here is more concentrated than nearly anywhere else in Nassau County.

Flexible Liner
Older Hempstead chimneys are rarely perfectly straight. A 1930s colonial near Hempstead Turnpike might have a slight offset where the flue passes the smoke chamber, and that’s where a flexible liner makes sense. A rigid liner would require cutting into masonry. A flexible stainless liner follows the existing path and gets the job done without turning a one-day reline into a two-week reconstruction. We’ll show you the measurement and the path on camera before we quote it.

Liner Replacement
If you already have a liner but it’s cracked, separated at a joint, or sized for an oil furnace that’s now gone, we replace it. The old terra-cotta liners common in 1940s and 1950s Hempstead Capes crack under decades of freeze-thaw cycling, and salt-laden air off the South Shore accelerates the damage. We pull the old liner, inspect the surrounding masonry, and install a new liner sized to the actual appliances venting through it. No guesswork. We measure, we calculate, and we show you the numbers.

Partial Rebuild
Sometimes the liner is fine but the chimney above the roofline is failing. Spalled bricks, crumbling mortar joints, a cracked crown. In Hempstead’s coastal air, mortar joints often look intact from the street but crumble on contact once we’re on the roof. A partial rebuild replaces the damaged courses, rebuilds the crown with a proper overhang and drip edge, and leaves the lower chimney untouched. It’s a targeted repair, not a full tear-down, and it costs significantly less. We’ll tell you if that’s all you need.

Full Chimney Rebuild
When the structural damage runs deep, a full rebuild is the only honest recommendation. We tore down and rebuilt a 1938 brick colonial near Hempstead Turnpike last season. The terra-cotta flue had cracked under years of salt air and freeze-thaw cycling, the mortar joints were dust, and the crown had been patched so many times it was more patch than crown. We pulled the whole thing, installed a DuraFlex stainless liner, rebuilt the chimney, and cleared the shared flue that served both a converted gas boiler and the living-room fireplace. The homeowner got a clean Level 2 inspection for their title. That’s the standard here.

Trusted Brands We Service in Hempstead
We install and service liners and components from DuraFlex, Olympia Chimney, Famco, and Copperfield, and we stock the parts Hempstead jobs actually need, so we’re not waiting on a distributor in another state when your liner needs to go in before a closing. These are brands we’ve worked with for years, not whatever a supply house happened to have on sale that week. If you already have a liner from one of these manufacturers and it’s failing, we’ll tell you whether it can be repaired or needs to come out, and you’ll see the reason on camera before you spend anything.
Common Chimney Liner & Rebuild Problems We See in Hempstead Homes
- Shared flues failing modern inspections. Many 1920s-1950s Hempstead homes have a fireplace and an oil furnace venting into the same flue. It was grandfathered in for decades. Now, when the oil furnace gets swapped for a gas boiler, inspectors flag the shared setup, and the homeowner finds out at the closing table. We fix this constantly.
- Missing or destroyed clay tile liners. Original single-wythe brick chimneys in Hempstead were often built with no liner at all, or with clay tiles that cracked within twenty years. Condensation from lower-temperature gas appliances accelerates the damage from the inside out, where nobody can see it until we scope the flue.
- Salt-air mortar failure. Hempstead sits 10-15 miles from the Atlantic and Great South Bay. Salt-laden air attacks mortar joints and metal flashing faster than inland Long Island. Mortar looks fine from the ground. On the roof, it crumbles when you touch it. That’s how a chimney gets to the point of a partial rebuild before anyone notices.
- Gas conversion without relining. Homeowners convert from oil to gas and assume the chimney is fine. It’s not. The oversized flue that worked for a hot oil exhaust now collects acidic condensation from a cooler gas exhaust, and the masonry starts dissolving. A reline at the time of conversion is half the cost of a rebuild three years later.
Pricing for Chimney Liner & Rebuild in Hempstead, NY
You deserve real numbers, so here they are. A stainless steel liner installation in Hempstead typically runs $1,800-$4,200, depending on flue height, liner diameter, and whether we’re working from the roof or through the firebox. A flexible liner job runs on the lower end of that range. Liner replacement with tear-out of old terra-cotta runs $2,500-$5,000. A partial rebuild, including crown work and repointing above the roofline, runs $2,800-$6,500. A full chimney rebuild in Hempstead starts around $7,500 and can reach $14,000 for a large two-story chimney with multiple flues. These are Hempstead market prices, not national averages. Factors that move the number: roof pitch and access, flue height, whether scaffolding is required, and the condition of the surrounding masonry. Every quote is free, in writing, and the price we quote is the price you pay. We also offer $40 off any repair over $200, a free second opinion on any competing written estimate, and 10% off always for seniors and veterans.

FAQs - Chimney Liner & Rebuild in Hempstead
Yes, the Town of Hempstead building department requires a permit for chimney liner installations, and we handle the permit paperwork as part of the job. Nassau County inspectors have been increasingly flagging shared oil-furnace/fireplace flues during real-estate transactions, which means we often get called in by an attorney or real-estate agent trying to clear a title issue before closing, not by a homeowner who noticed a problem. If you’re buying or selling in Hempstead and the chimney comes up on an inspection report, call (516) 963-1068 and we’ll walk you through exactly what the permit process looks like and what the inspector will want to see.
No, and this is the most common compliance failure we see in Hempstead. The shared flue that worked for oil was grandfathered in, but once you convert to gas, the lower-temperature exhaust creates condensation that the oversized, unlined flue was never designed to handle, and modern inspections will not pass it. The fix is usually a properly sized stainless steel liner dedicated to the gas appliance, with the fireplace either getting its own liner or being sealed off. Call (516) 963-1068 and we’ll scope the flue so you can see exactly what the inspector will see.
Because in Hempstead, the damage that matters is rarely visible from the street. Salt-laden air off the South Shore attacks mortar joints from the outside while condensation from a gas conversion eats them from the inside, and the result is a chimney that looks intact but crumbles on contact once we’re on the roof. We’ll show you the camera footage and give you a plain-English verdict. If a partial rebuild will do the job, we’ll tell you that. If the base is shifting or the flue is compromised down to the firebox, a full rebuild is the only honest answer, and we’ll show you why before you commit to anything.
Yes, and in older Hempstead homes, offsets are common. A rigid stainless liner wants a straight run, but a flexible liner follows the existing path through the smoke chamber and up the flue without cutting into the masonry. We measure the flue, confirm the offset on camera, and size the flexible liner to the actual length and diameter your appliances require. The result is a clean, code-compliant installation that doesn’t turn a one-day job into a demolition project. Call (516) 963-1068 for a free estimate.
What happens next is that we scope the flue, document the condition on camera, and give the attorney and the seller a written report with a plain-English recommendation. If it’s a cracked liner only, the fix is usually a stainless steel reline, and we can often get it done before the closing date with a permit from the Town of Hempstead. If the masonry around the liner is also failing, we’ll quote a partial or full rebuild and explain which one is actually necessary. We do this constantly in Hempstead, and we know what the local inspectors and title companies need to see. Call (516) 963-1068 and we’ll get the camera in the flue this week.
