If you own one of the split-levels or ranches built across Plainview in the 1950s and 60s, you already know these houses were framed around brick chimneys that have now seen six or seven decades of Long Island weather. We work those same blocks every week, from the streets north of Old Country Road down to the neighborhoods around the Plainview-Old Bethpage border.

We arrive in uniform, we show up inside the window we give you, and we document everything on camera before recommending a single repair. No guesswork. No scare tactics. Just a written scope and a price you can hold us to.

Styles & brands we work with





Chimney Cap Replacement in Plainview
Chimney cap replacement in Plainview addresses the single most common entry point for water, animals, and debris in a 1950s or 60s chimney. On homes throughout Plainview, we routinely find rusted galvanized caps that have warped, pulled loose from the flue tile, or gone missing entirely after a nor’easter. A proper replacement cap – typically stainless steel from Olympia Chimney or Famco – keeps rain out of the flue, blocks squirrels and raccoons from nesting, and stops sparks from escaping onto roof shingles.
What the Job Involves
We measure the flue opening, remove the old cap and any damaged mortar from the crown, and install a correctly sized cap with a mesh screen. On Plainview homes where the flue tile extends only an inch or two above the crown, we often need to build up the mortar or install a cap designed for a low-profile flue. The job usually takes under an hour once we’re on the roof. Cost in Plainview runs $225 – $425 including the cap and labor, depending on flue size and whether the crown needs patching.
When Plainview Homeowners Actually Need One
You need a cap replacement if you can see daylight through the top of your flue, if you’ve heard animals inside the chimney, or if the existing cap is rusted through. The freeze-thaw cycles Plainview gets every winter crack the mortar bed under the cap, and once water settles there, the crown starts spalling. That’s how a $300 job becomes a $1,200 crown rebuild. We’d rather catch it early and show you the camera view before recommending anything.
Chimney Liner Installation in Plainview
Chimney liner installation in Plainview means replacing the inner pipe or clay tile that channels smoke and exhaust safely out of the house. This is the repair we recommend most often in the older sections north of Old Country Road, where original terra cotta liners have cracked from decades of heating-oil soot. When a Plainview homeowner switches from oil to gas, the acidic gas exhaust accelerates that damage. At Flint Chimney Co Hempstead, we never recommend a liner replacement without first running a Level 2 camera inspection and showing you exactly what the video reveals. Hank Delano’s policy is simple: no camera evidence, no liner recommendation.
Stainless Steel Liners for Gas and Oil Conversions
For most Plainview homes, we install DuraFlex stainless steel liners – a flexible, UL-listed system that handles both gas and oil exhaust without corroding. The liner gets sized to your furnace or water heater’s BTU output, not to whatever pipe happened to be on the truck. Typical cost for a gas conversion liner in Plainview runs $2,800 – $4,200. It’s a one-day job in most cases, and we cap the flue top and bottom, install a rain cap, and photograph the finished installation for your records.
Why a Patch Job Usually Fails
A contractor might offer to “repair” a cracked terra cotta liner by parging over it with refractory cement. In a Plainview home that’s been converted to gas, that patch gets eaten through within a season or two. The acidic condensate from gas exhaust degrades the parge coat, and you’re back to the same draft problem with less money in your pocket. If the camera shows spalling or gaps between tiles, replacement is the honest answer. We’ll tell you that directly, with the video pulled up so you can see it yourself.
Trusted Brands We Service in Plainview
We stock and install professional-grade chimney products from manufacturers that publish their specs and stand behind their warranties. For liner work across Plainview, we specify DuraFlex stainless systems because they’re built for the acidic exhaust conditions common after oil-to-gas conversions. Our cap replacements draw from Olympia Chimney and Famco, both of which make heavy-gauge stainless caps that hold up to Long Island coastal air. For crown repair and waterproofing, we use Copperfield products when the job calls for it. Because we keep common sizes on our trucks, most Plainview jobs don’t need a second visit for parts. You approve the brand and the part before we install it, and the written quote tells you exactly what’s going in.

AfterCommon Chimney Repair Problems We See in Plainview Homes
- Cracked terra cotta liners north of Old Country Road. Original clay tiles from the 1950s and 60s crack after decades of oil soot. Gas conversion accelerates the damage. The fix is a Level 2 camera inspection first, then a stainless liner if the tiles have failed.
- Freeze-thaw damaged flashing and crowns. Plainview’s winter cycles – freezing nights, thawing days – open gaps where the roof meets the chimney. Water gets behind the flashing, rots the decking, and cracks the crown. Repointing the brick without addressing the crown just lets water keep entering.
- Unused chimneys after oil-to-gas conversion. Many Plainview homeowners think a converted chimney needs no attention. What we actually find is first-degree creosote from the oil years, animal nests, and hidden gaps now venting CO into the house. An inspection costs a fraction of the risk.
- Spalled brick at the roofline. The brick sections above the roofline on Plainview’s split-levels take the worst of the weather. Once the brick face starts popping off, water intrusion accelerates, and you’re looking at partial rebuilding rather than simple repointing.

FAQs About Chimney Repair in Plainview
Do I still need a chimney inspection if I switched from oil to gas heat in Plainview?
Yes. Switching to gas does not make your chimney safe by default. The oil years left creosote, soot, and possibly animal nests inside the flue. Gas exhaust is acidic and accelerates damage to old terra cotta liners. In Plainview homes north of Old Country Road, we find cracked clay tiles and failed dampers in chimneys that were “never used anymore” after conversion. A Level 2 camera inspection gives you the answer in one visit. Call (516) 559-6922 to book yours.
My home north of Old Country Road still has the original terra cotta liner. Can it be repaired instead of replaced?
In most cases, no. Terra cotta tiles that have spalled or separated cannot be patched in a way that lasts. Parging over the cracks is a temporary fix that gas exhaust deteriorates within a season or two. The honest answer is replacement with a stainless steel liner sized to your appliance. We’ll show you the camera footage before we recommend anything, so you’re not taking our word for it. Call (516) 559-6922 for a free estimate.
Why does the chimney crown matter if I have a chimney cap?
The cap covers the flue opening. The crown is the mortar or concrete slab that covers the top of the brick chimney structure itself. Water that lands on the crown seeps into the brick below if the crown is cracked. In Plainview’s freeze-thaw winters, that water freezes and pops brick faces off. We see chimneys with perfectly good caps and failing crowns all the time. The fix is a new crown, and it’s far less expensive than rebuilding the top three feet of your chimney. Call (516) 559-6922 and we’ll inspect yours.
My fireplace has a third-degree creosote glaze. Can you just brush it out?
No. Third-degree creosote is a hard, tar-like glaze that standard brushing won’t remove. Burning a fire under those conditions is a chimney-fire risk. It requires chemical treatment or mechanical removal with rotary tools, and depending on the flue condition, possibly a liner replacement afterward. A chimney sweep in Plainview should inspect before recommending anything. Our crew was called to a split-level north of Old Country Road after a gas conversion left the homeowner with a drafty, whistling flue. The camera showed a clay tile liner spalled in three places, with first-degree creosote hiding behind a partially failed damper. We installed a DuraFlex stainless liner and a new chimney cap in the same visit – no guessing, just the video the homeowner watched with us. Call (516) 559-6922 for an inspection.
How do I know if I need a new damper or just a repair on my old split-level chimney?
The camera tells you. A damper that’s rusted through, warped, or detached from its frame is a replacement. A damper that’s merely stiff or slightly misaligned can often be repaired or adjusted. On Plainview’s 1950s and 60s split-levels, we frequently find original dampers that were never designed for gas inserts or have rusted from years of rain coming down an uncapped flue. The inspection shows us which situation you have. Then you get a written price for the work. Call (516) 559-6922 to schedule.
