HeatShield Chimney Liner & Rebuild Nationwide

HeatShield Chimney Liner & Rebuild in Hempstead: What to Know First

We repair and rebuild HeatShield chimney liners in Hempstead, NY, and most jobs wrap up in one to two days once we’ve seen the flue. HeatShield’s cerfractory coating system works well when it’s intact, but when it starts spalling or separating from the flue wall, you need someone who actually knows the product, not someone learning on your roof. If you own a HeatShield liner in Hempstead and it’s showing problems, or you want a straight answer on whether it needs attention, call (516) 963-1068 and we’ll schedule a camera inspection. We give you the footage, tell you plainly what it means, and quote the repair before any tool comes off the truck.

This page is for Hempstead homeowners dealing with HeatShield liner deterioration, cracked flue tiles behind the coating, or thinking about whether a rebuild is smarter than another patch. Wendell Pike and his crew have been repairing chimney liners across Hempstead and Long Island for over 29 years. As an independent HeatShield service provider, we’re not tied to the manufacturer’s sales playbook, and if we think a repair can wait, we’ll say so – in writing, if you want it.

How HeatShield Products Fail - and How We Fix Them

HeatShield has a good concept – a cerfractory sealant pumped up the flue to fill gaps and smooth the surface. But any product installed inside a chimney lives a rough life. Here’s what we actually run into in Hempstead homes:

• HeatShield Eco-Fix spalling at the smoke chamber. This entry-level application is a thinner coating, and in older Hempstead homes with oversized smoke chambers, it tends to flake off within five to eight years. The cause is thermal cycling; every fire expansion-and-contraction cycle works the coating loose from the parged surface. Our fix is removing the loose material, evaluating what’s underneath, and either reapplying with proper surface prep or stepping you up to a more durable solution if the underlying masonry is shot.
• HeatShield Cerfractory P2A delamination at flue tile joints. This is the one we see most. The P2A formula is HeatShield’s mid-range coating, and on tiles with even minor offset at the joints, the coating bridges the gap beautifully until year three or four, when cracked tile edges start moving with freeze-thaw cycles. The coating can’t flex, so it separates from the tile and hangs. Camera inspection shows what looks like peeling paint inside the flue. We fix it by removing delaminated sections, addressing the root cause (usually missing mortar or tile displacement), and relining with stainless steel where HeatShield can’t hold.
• Joint filler failure on HeatShield’s repaired mortar joints. HeatShield works partly by filling eroded mortar joints between flue tiles. Those filled joints are smoother than open gaps, but they’re only as strong as the tile they sit between. In Nassau County’s wet-dry freeze cycles, tiles shift. The filler cracks at the joint line and falls away in small chunks. We find these on camera as clean vertical fissures. If the tile structure is still stable, a targeted HeatShield reapplication works. If not, it’s a rebuild conversation, not another patch.
• Corrosion breakthrough at the flue base with HeatShield joint sealant only. Some homes got a partial HeatShield application – just the joints sealed, no full coating. At the first flue tile above the firebox, creosote and moisture settle, and over time the sealant at that junction degrades. Water gets behind it, sits against the tile, and when chimney fires happen, the thermal shock cracks the tile at that beltline. We see this in Hempstead homes with older fireplaces that burn a lot of pine. The real fix is usually a stainless liner from DuraFlex, sized to the appliance, with proper insulation. HeatShield wasn’t designed to handle that kind of thermal load alone.
• HeatShield 360 full resurfacing that fails after ignition without insulation. The 360 system is their most complete application, but in unlined exterior chimneys in Hempstead, the masonry behind it keeps conducting cold. The coating gets brittle, hairline cracks appear, and before long the flue gases find them. We remove what’s left, rebuild the damaged brick at the crown and upper courses, and install a properly insulated liner system. HeatShield 360 on an uninsulated exterior chimney is a known weak spot in this climate, not a guessed-at one.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Call and talk to a person. You call (516) 963-1068, Wendell or one of the crew answers. We set a real arrival window, and if we’re running late, you get a phone call, not a surprise.
2. 2
   Camera inspection first. We run a camera down the flue from the crown, and you watch the screen with us if you want. You keep the footage. We document every crack, delamination, and failed joint with timestamps.
3. 3
   Plain-English diagnosis. We tell you what the camera showed, what it means, and what can wait. If your HeatShield liner has three more years, we’ll tell you. If it doesn’t need work at all, we’ll tell you that too. If it doesn’t need doing, including a repair, we’ll say so.
4. 4
   Parts decision – OEM vs. what actually holds up. For HeatShield reapplications, we use HeatShield material. For repairs where HeatShield isn’t the right product, we tell you why and quote a stainless alternative from DuraFlex or Gelco. No mystery substitutions. You see the line item before we start.
5. 5
   The repair or rebuild. For liner repairs, we remove failed material, prep the surface correctly, and reapply. For rebuilds, we set up staging, tear down what’s unsafe, and rebuild with the same tools and pace we’ve used on Hempstead chimneys for 29 years.
6. 6
   Test fire, cleanup, and the 90-Day Done Right Promise. We light a test fire, check the draw, sweep up every bit of dust and debris, and hand you the warranty paperwork. If anything’s not right within 90 days, one call brings us back at no charge.

What HeatShield Chimney Liner & Rebuild Costs in Hempstead

HeatShield work varies widely because it depends on what the camera shows. A targeted joint repair or small reapplication in a Hempstead single-story home can run $1,200 to $2,800. A full HeatShield 360 removal and stainless liner replacement typically lands between $3,800 and $7,500, depending on flue height, access, and whether we’re rebuilding sections of the chimney at the same time. A partial rebuild of the crown and top few courses adds $1,500 to $4,000. A full chimney rebuild from the roofline up in Hempstead usually runs $8,000 to $15,000, and more if the firebox needs work.

What moves the price here is access, mainly. Exterior chimneys with a clean roof line get done faster. Interior chimneys through the middle of the house, or rooflines near Hofstra-area split levels with steep pitches, take more time and staging. Also, the more HeatShield material we have to remove before starting fresh, the higher the labor. We give you a flat price before we start, and the number you hear is the number you pay.
