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.

AfterFast, Reliable Chimney Repair Across Franklin Square
Chimney repair in Franklin Square usually means one of three things: repointing crumbling mortar joints, rebuilding a cracked crown, or replacing a clay tile flue liner that’s been eaten from the inside since the house switched from oil to gas. Most jobs on the Cape Cods and small ranches that fill this hamlet run between $400 and $3,800 depending on what the camera finds. We schedule Franklin Square calls within three to five business days, and every repair starts with a written price and a camera inspection you can watch over our shoulder. Call (516) 240-9612 and we’ll get a Level Two team to your street fast.
Why Level Two Chimney Jamaica Is Franklin Square’s Preferred Chimney Repair Company
Franklin Square homeowners call us because we show them the damage before we ask for a dollar. Our technicians run a camera down every flue, photograph every crack, and then sit down with you to look at the footage. We don’t ask you to take our word for a liner replacement. You see it with your own eyes. That’s been our standard since 2009, and it’s Clause 4 of the Haven Standard: a documented photo record on every visit, every time.
We know these streets. The Cape Cods off Hempstead Turnpike, the ranches along Washington Street, the colonials tucked between Fenworth Boulevard and Pacific Street. When Corrine Halstead dispatches a crew to Franklin Square, she sends technicians who’ve already worked a dozen houses like yours in this zip code. They know that a rear chimney on a 50-foot lot means talking to the neighbor before setting a ladder, and that a 1955 clay tile liner behind a gas furnace is a problem waiting to be photographed.
Our customers in Franklin Square mention the same thing in reviews: the price was on paper before work started, and the photos backed up every recommendation. No estimates over the phone that quietly double. No “you need a new liner” with zero evidence. Just documentation, a written scope, and a written warranty. Clause 1 of the Haven Standard: have it in writing.

Our Chimney Repair Services in Franklin Square
Mortar Repointing
Homes in Franklin Square built between 1945 and 1965 now have mortar joints that have endured 60 to 80 winters of Nassau County freeze-thaw cycling. Moisture gets into the joints, freezes, expands, and slowly crumbles the mortar from the surface inward. Repointing removes the failed mortar and replaces it with a mix matched to your brick’s compressive strength and color. On a typical Franklin Square cape, repointing a single face of the stack runs $45 to $75 per square foot depending on access and joint depth.
Spalling Brick Repair
Spalling is the word for brick that flakes, chips, or sheds its face. It’s common on Franklin Square chimneys where water has wicked into the brick and frozen repeatedly. The face of the brick pops off, leaving a pitted surface and exposing the softer interior. On narrow lots where chimneys sit close to a neighbor’s fence or roof, falling spalled brick is a real hazard. We replace the damaged brick, match it to the original color and texture, and address the moisture source so the problem doesn’t return. A typical partial spall repair in Franklin Square runs $350 to $900 depending on how many brick are involved and how high the damage sits.
Chimney Waterproofing
A chimney crown in Franklin Square takes a beating from Atlantic moisture and November-through-March freezes. If the crown is cracked or unpainted, water moves into the stack and starts the freeze-thaw failure cycle. We apply a vapor-permeable waterproofing treatment, typically a Gelco product, that stops liquid water from entering while still letting the masonry breathe. Before we quote waterproofing, we show you the moisture evidence on camera. Franklin Square homeowners pay $250 to $700 for a standard chimney waterproofing depending on stack height and surface condition.
Flashing Repair
Flashing is the metal seal where the chimney meets the roof. On Franklin Square’s older homes, we commonly find original galvanized flashing that’s rusted through at the corners or separated from the masonry. A compromised flashing lets water run down the chimney interior and into the attic. We remove the old flashing, inspect the substrate, and install new step and counter flashing. A flashing repair on a single-story Franklin Square ranch typically runs $400 to $950.

We install and repair chimney systems built with materials we know hold up in Nassau County’s marine air. That means stainless liners from DuraFlex, heat-shield resurfacing products from HeatShield, and crowns and caps from Copperfield. We keep common Franklin Square liner sizes and cap dimensions in stock through our procurement network, which shorts the lead time on most repairs in this hamlet. When you need a liner insert in a 1950s Cape Cod, we’re not waiting two weeks on a special order from a distributor warehouse.
Common Chimney Repair Problems We See in Franklin Square Homes
- Oil-to-gas liner failure: Franklin Square’s post-war housing stock was built around oil-fired furnaces, and the clay tile flue liners installed for those systems are oversized for modern gas appliances. The acidic condensate from gas exhaust eats through the tile from the inside, leaving hidden damage behind intact-looking brick. Most “sweep” calls on these homes end with us showing the homeowner a photo of a cracked, spalled liner they didn’t know they had.
- Crown cracking from freeze-thaw cycling: Nassau County’s humid marine climate pushes moisture into chimney crowns all fall, and winter freezes expand that moisture. Cracks deepen every year. By the time you can see the damage from the yard, water has likely already been moving through the crown for several seasons.
- Mortar joint erosion on 70-year-old stacks: The original mortar used on Franklin Square homes built in the 1950s and early 1960s has a lifespan of roughly 50 to 70 years. Most of those chimneys are at or past the end of that window. We find sand-like powder sluicing down the flue and missing mortar beds even when the exterior brick still looks serviceable.
- Staging and access complications on tight lots: Because many Franklin Square rear chimneys are boxed between close-set structures, a proper repair requires ladder staging that crosses a property line. We coordinate with neighbors early, schedule the work with enough time to set up safely, and never skip the camera inspection just because access is inconvenient.

FAQs - Chimney Repair in Franklin Square
Because Franklin Square’s homes were built between 1945 and 1965 with oil-fired heating systems, and the clay tile flue liners sized for oil are oversized for today’s natural gas furnaces. Gas exhaust is cooler and carries acidic condensate that condenses inside the tile and eats it from the inside out. By the time we put a camera down the flue, the liner is often fully spalled or cracked behind intact exterior brick. A sweep can’t fix that. A stainless liner insert from DuraFlex can. Call (516) 240-9612 and we’ll show you the camera footage of your liner before recommending anything.
Yes, we prove it with camera footage and close-up photos of the crown surface, the mortar joints below it, and any water staining inside the flue. A crown that’s legitimately letting water in will show hairline cracks, eroded areas around the flue tile, or a visible gap between the crown and the brick. We don’t recommend waterproofing unless we can show you the entry points. That’s the whole point of our Level 2 inspection standard.
In most cases, yes. Spalling brick replacement is a face repair, not a teardown. We remove the damaged bricks, install color-matched replacements, and address the moisture source with repointing or waterproofing so the new brick doesn’t start spalling too. On extremely narrow side yards where the chimney is boxed in against a fence, we coordinate ladder staging with the neighbor and schedule the work with enough time to set up safely. The only time we recommend a full rebuild is when more than about a third of the brick face is compromised or the structural core is deteriorating.
Yes, and a cap does more than keep out rain. It also keeps leaves, twigs, birds, and squirrels out of a flue that’s sitting unused most of the summer while your furnace is off. On Franklin Square’s tightly spaced lots, a missing cap also lets wind-driven debris blow sideways into the flue. A stainless cap from Copperfield installed on a gas vent runs $200 to $500 depending on flue size and whether we need to build a crown extension to mount it properly.
Repointing is surface repair: we grind out the failed mortar joints to a depth of about three-quarters of an inch and pack in new mortar. It’s appropriate when the brick itself is sound and only the joints have failed. Rebuilding means removing and re-laying brick. We recommend that when the mortar failure is so deep that the structural integrity of the stack is compromised, or when more than a third of the bricks themselves are spalled or cracked. Rebuilding costs more because it’s more labor, but on many Franklin Square chimneys with interior liner damage, the repair ends up being a liner insert plus repointing, not a full rebuild. We’ll show you the difference on camera and give you a written recommendation you can hold in your hand.
If you need a straight answer about your chimney in Franklin Square, call (516) 240-9612. We’ll schedule the camera inspection, hand you a written price before any work starts, and leave you with a photo record of exactly what we did. That’s the Level Two standard, and it’s been that way since 2009.
