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.

Why Flint Chimney Sweep Is Ambler’s Preferred Chimney Repair Company
Flint Chimney Sweep has been operating since 2002 as part of the Garrison Partners family of independently owned chimney service companies, and Ambler homeowners tend to call us for one reason: we put everything in writing. The 365-Day Done Right Promise means every repair we complete in Ambler carries a written guarantee valid for one full year from the service date. If a covered repair fails during that window, we return at no charge. No argument, no second invoice.
The technicians who come to your Ambler home are background-checked and uniformed. You know who’s walking through the door before they arrive. Our phones are answered by a live person 24 hours a day, seven days a week, so you’re never leaving a voicemail and hoping for a callback. For Ambler homeowners off East Butler Avenue or up near the Wissahickon Creek corridor, that means you reach a person, not a phone tree, even on a Sunday night when you notice water streaking down your chimney breast.
Hank Delano leads our repair work with a straight-talking approach: no upselling, no vague assurances. Just documented findings, a flat price, and a photo report you can keep. That’s why Ambler residents who’ve been burned by no-show companies or door-price changes call Flint first.
Chimney Cap Replacement in Ambler
Chimney Cap Replacement in Ambler usually costs between $350 and $850, and it’s one of the most common repairs we do on homes near the SEPTA rail line where original brick chimneys have taken a century of weather. A chimney cap does two jobs: it keeps rain and snow from pouring directly down the flue, and it keeps animals, leaves, and debris out. When the cap rusts through or the mesh screen tears, water gets in and starts working on the masonry from inside.
Signs a Cap Needs Replacement
Walk outside and look up. If you see rust streaks on the exterior chimney, a cap that’s tilted or missing entirely, or birds roosting inside the flue, the cap has failed. In Ambler’s older housing stock, we frequently find original copper or steel caps that have corroded past saving. A replacement cap with proper screening stops the water intrusion before it reaches your liner and firebox.
What the Repair Involves
We measure the flue opening, supply a correctly sized cap, and seal it to the crown with proper fasteners, not just caulk. For Ambler homeowners with multiple flues, we’ll check each one. The written price covers the cap, the labor, and the sealant. We don’t add a “materials surcharge” at the door.
Chimney Liner Installation in Ambler
Chimney Liner Installation in Ambler typically runs $2,500 to $4,500 for a full relining, depending on the flue dimensions, the liner material, and access from the roof. A chimney liner is the inner pipe that channels smoke and combustion gases safely out of the house. When that liner cracks, separates, or washes out inside a century-old Ambler flue, the chimney can leak carbon monoxide into the living space and hot gases into the masonry.
When a Liner Must Be Replaced
We recommend a liner inspection any time a home in Ambler has been converted from oil to gas heat, because gas exhaust is cooler and more corrosive to older clay tile liners. If your inspection shows a cracked clay tile, a liner that has separated at the joints, or a perforated metal liner, the fix is not a patch. It’s a full reline with a DuraFlex or HeatShield system sized for your appliance. We name the brand on your written quote so you can verify it yourself.
Liner Materials We Use
For most Ambler homes, we install DuraFlex stainless steel liners because they handle gas, oil, and wood exhaust well and carry a strong warranty. For chimneys with compromised original flues, HeatShield’s cerfractory coating can sometimes reline the existing flue without demolition. We’ll tell you which one fits your chimney and why. We never pick the material by margin.
Trusted Brands We Service in Ambler
We work with professional-grade chimney products from brands you can look up and verify: DuraFlex for stainless steel liners, HeatShield for cerfractory flue restoration, Gelco for caps and chase covers, Olympia Chimney for flashing and crown sealants, Famco for dampers and vents, and Copperfield for custom caps and shrouds. We stock common replacement parts for Ambler homes, which means less waiting on a supplier and faster turnaround when your cap is rusted through or your damper plate has cracked. Every brand we specify goes on your written quote, so you know exactly what’s being installed.
Common Chimney Repair Problems We See in Ambler Homes
- Spalling brick and softened lime mortar on century-old chimneys near Butler Avenue and the rail corridor. What starts as a cosmetic issue, a few flaking bricks, becomes a structural problem when freeze-thaw cycles open the crown and let water into the flue. A camera inspection catches this before the chimney leans.
- First-degree creosote mistaken for “just soot.” Ambler homeowners with wood-burning fireplaces frequently defer a sweep because the buildup looks light. First-degree creosote is flaky and easy to brush out. Second-degree glazed creosote requires chemical treatment or HeatShield restoration, and third-degree is a fire hazard inside the flue.
- Dampers that won’t seal. In older Ambler twins and rowhomes, we regularly find original cast-iron dampers that have warped or rusted. The homeowner keeps the fireplace clean but misses a damper that’s letting conditioned air escape and water drip down the flue. A Level 2 inspection catches this in minutes.
- Crown cracks from missing or failed chimney caps. Without a functioning cap, rain and snow fall directly into the flue and sit in the smoke chamber. Repeated wetting and drying destroys the interior masonry faster than any exterior weather.

FAQs About Chimney Repair in Ambler
Every year, especially if you burn wood. The National Fire Protection Association recommends annual inspection regardless of fuel type, and Ambler’s older brick chimneys make that schedule the minimum, not the maximum. A short Level 1 inspection catches small crown cracks and early creosote before they become repair jobs. If you burn wood weekly, a sweep plus visual inspection every year is appropriate. One exception: after buying an older Ambler home where the chimney history is unknown, get a Level 2 camera inspection before lighting the first fire. Call (830) 251-4560 for a flat-price sweep and inspection quote.
Third-degree creosote is a hardened, tar-like glaze that has baked onto the flue wall after repeated low-temperature fires. A standard chimney brush will not remove it. It requires rotary cleaning tools or chemical treatment, and in severe cases a HeatShield resurfacing. Third-degree creosote is also the form most likely to ignite during a chimney fire because it burns hot and fast. If you’re burning green or unseasoned wood in your Ambler fireplace, you’re feeding this problem. Get it checked with a camera so you know what degree you’re dealing with. Call (830) 251-4560 to schedule an inspection.
White staining on exterior brick is called efflorescence, and it means water is moving through the masonry. The water dissolves salts inside the brick and mortar, carries them to the surface, and leaves the white deposit when it evaporates. In Ambler’s older homes with original lime mortar, this is common because lime mortar is more porous than modern cement-based mortar. The fix is not to paint over it. The fix is to identify where the water is entering, usually a failed crown, a missing cap, or deteriorated flashing, and repair that first. A camera inspection plus a masonry evaluation tells you what’s leaking. Call (830) 251-4560 for a free estimate.
For standard repairs like cap replacement and mortar repointing, yes. We can often quote a flat price over the phone based on the chimney’s height, the repair type, and photos you send. For anything structural, a liner, a rebuild, a flashing repair, we send a technician to run a camera inspection and then provide a written price before any work begins. The price on the quote is the price on the invoice. We’ve operated this way since 2002 under The Garrison Standard, and we don’t open the work without your signed approval. Call (830) 251-4560 and ask for Hank Delano.
Some things can wait; some cannot. A hairline crack in a chimney crown with no water intrusion can safely wait a season. Minor flaking on exterior brick that hasn’t opened into the flue can wait. First-degree creosote can wait until the next sweep if you’re not burning regularly. What cannot wait: a cracked flue liner, because that’s a carbon monoxide risk. A chimney with missing flashing in Ambler’s wet winters cannot wait, because water is actively entering the house. A damper that won’t seal should not wait, because you’re losing heated air and inviting moisture year-round. Call (830) 251-4560 and we’ll tell you honestly which camp your chimney falls in.
