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 Bala Cynwyd
Chimney repair in Bala Cynwyd, PA typically runs $185 – $3,800 depending on whether you’re fixing a cracked crown, relining a flue, or rebuilding masonry above the roofline. Most repairs we handle in the 19004 ZIP are water-related, not creosote-related, because so many homes here were built between the 1920s and 1950s with soft local brick and slate roofs. Flint Chimney Sweep serves Bala Cynwyd with written pricing agreed before any work starts and a full-year guarantee on every repair. Call (830) 251-4560 for a free estimate, or keep reading to see what a proper repair actually involves in this town.
Bala Cynwyd is a place where stone colonials and stucco-sided houses sit on tree-lined streets off Montgomery Avenue and City Avenue, and the chimneys on those homes were built to a different standard than anything going up in newer developments. That matters when a crew knocks on your door and starts talking about what’s wrong above the firebox. Our technicians know the housing stock here: slate roofs, low-slope sections, original masonry that has been taking on Philadelphia-area weather for 70 to 100 years. We work on those chimneys every week.
Why Flint Chimney Sweep Is Bala Cynwyd’s Preferred Chimney Repair Company
Flint Chimney Sweep has been part of the Garrison Partners family since 2002, and the way we operate in Bala Cynwyd comes down to the Garrison Standard: a written price before any tool leaves the truck, a written guarantee on every repair, and a live person answering the phone 24/7. No voicemail trees, no callbacks on Monday morning. You call, a person picks up, and you get a straight answer.
Homeowners around Bala Cynwyd keep our number because we do not move the price at the door. The figure on your invoice is the figure you approved before we booked the job. Every technician who shows up in Bala Cynwyd is background-checked and uniformed, so you know exactly who is walking through your front door. And every repair carries the 365-Day Done Right Promise: if a covered repair fails within one full year, we return at no charge, no argument, no second invoice.
We also know what we are looking at when we climb onto a slate roof off Levering Mill Road or inspect a chimney from a back patio in the Bala neighborhood. That local familiarity means fewer misdiagnoses and less wasted money on repairs you did not need. Hank Delano leads the company with a straightforward rule: document everything. If we tell you a crown is cracked or a liner is failing, you will see it in the photo report.
Chimney Cap Replacement in Bala Cynwyd
Chimney cap replacement is one of the most common calls we get from Bala Cynwyd homeowners, especially on older homes where the original cap has rusted through or blown off entirely during a Nor’easter. The cap is the metal cover and screen assembly that sits on top of the flue opening, and in Bala Cynwyd it does two jobs: it keeps rain from running straight down into the smoke chamber, and it keeps squirrels, raccoons, and birds from nesting inside your chimney. A standard chimney cap replacement in Bala Cynwyd runs $185 – $425 depending on flue size and whether the cap needs a custom fit for a slate-roof mounting.
Signs Your Cap Has Failed
If you hear animal noise from the flue or see water staining on the firebox side wall after heavy rain, the cap is usually the first thing we check. Rusted or missing caps also let rain pool at the base of the flue liner, which accelerates spalling on the surrounding brick. We replace caps with professional-grade material and photograph the install so you can see the work without climbing onto the roof yourself.
Slate Roof Mounting
On Bala Cynwyd homes with slate roofs, cap replacement needs to be done carefully so the mounting bracket does not crack surrounding slates. Our techs have worked on enough slate in this area to know that you do not walk on slate the way you walk on asphalt shingles. We use the correct flashing and mounting hardware for slate applications, and the written quote includes everything before we start.
Chimney Liner Installation in Bala Cynwyd
Chimney liner installation is the repair we never want to recommend without camera evidence, because replacing a liner is the single most expensive item on a chimney repair invoice. In Bala Cynwyd, a new flue liner typically runs $2,500 – $3,800 installed, depending on the length of the flue and whether we are using a flexible stainless system like DuraFlex or a poured product like HeatShield. The liner is the inner sleeve that channels smoke and combustion gases safely up and out of the house, and when it fails, the result can be carbon monoxide leaking into living space or heat transferring directly into the old masonry around it.
When a Liner Actually Needs Replacing
An older Bala Cynwyd stone house might have a clay tile liner that is cracked or spalling in sections. That is different from creosote buildup, which can be swept. We only recommend liner replacement when the camera inspection shows physical failure in the liner itself: cracks, gaps, or missing sections. The photo report goes to you before any quote is written, so you are making a decision based on what the inside of your chimney actually looks like, not what a technician tells you from the ground.
HeatShield vs. DuraFlex
For Bala Cynwyd homes where the existing clay liner is mostly intact but has gaps or minor cracks, we often specify HeatShield, a cerfied poured material that seals and restores the liner without a full tear-out. When the liner has failed beyond repair, we install a DuraFlex stainless system, which is the workhorse liner in this trade. The brand gets specified by the condition of your flue, not by what is in the truck that day, and both carry the same one-year written guarantee.
Trusted Brands We Service in Bala Cynwyd
We do not install whatever part happens to be cheapest this month. On Bala Cynwyd chimneys we work with professional-grade materials including DuraFlex for stainless liners, HeatShield for poured liner restoration, and Olympia Chimney cap and flashing components. Because we stock these parts for our local service area, we can usually schedule the repair and complete it in one visit without waiting on a backordered part. That means less time with a chimney offline and no second trip charge for a part that did not arrive.
Common Chimney Repair Problems We See in Bala Cynwyd Homes
- Soft brick spalling on 1920s – 1950s masonry. The original Philadelphia-area brick used on Bala Cynwyd chimneys is softer than modern brick, and after decades of freeze-thaw cycles it starts to flake and crumble. Homeowners see a pile of reddish dust at the base of the chimney and assume the flue is dirty. It is usually a masonry repair, not a sweep, and the fix is tuckpointing or spalling brick replacement before the chimney loses structural integrity.
- Crown and flashing failures at the roofline. Where the chimney meets a slate or low-slope roof on homes near the Cynwyd Heritage Trail or up toward Belmont Avenue, the crown cracks and the flashing pulls away over time. Water gets behind the flashing, runs down the exterior of the flue, and shows up as interior staining on the firebox wall. This is the most common “mystery leak” we diagnose in Bala Cynwyd.
- Glazed third-degree creosote hiding behind first-degree deposits. We have swept chimneys in Bala Cynwyd where the brush pulled out first-degree creosote but the camera showed a hardened, shiny third-degree layer behind it. A visual check from the firebox would not have caught it. That glazed layer is a chimney fire risk, and it does not brush out; it has to be removed chemically or with specialized rotary equipment.
- Missing or rusted dampers and caps. On older stone colonials off Llandrillo Road and in the Bala neighborhood, we regularly see dampers that stick halfway or have rusted completely in place. A failed damper is also a sign that rain has been getting past a missing or damaged cap for years, which means the firebox and smoke chamber have been taking on water every time it rains.
Pricing for Chimney Repair in Bala Cynwyd, PA
Here are the ballpark ranges for the most common repairs in Bala Cynwyd, so you know the number before you call: chimney cap replacement $185 – $425, mortar repointing and tuckpointing $375 – $900 for a typical crown-to-roofline section, chimney crown recasting $550 – $1,100, flashing repair $275 – $650, fireplace damper replacement $225 – $475, and full flue liner installation $2,500 – $3,800. A standard chimney sweep in Bala Cynwyd runs $185 – $275, and a Level 2 camera inspection is $275 – $400 if booked as a standalone.
What moves the price up is access. A chimney on a steep slate roof with difficult ladder placement costs more in labor than a straight shot up a shallow-pitch roof. A flue that needs scaffolding at the roofline will be higher than one reachable from a ladder. But whatever the job, you get a written flat price before we book, and the price on the invoice is the price you approved. Call (830) 251-4560 for a free estimate and we will put the numbers in writing.

FAQs About Chimney Repair in Bala Cynwyd
An older stone house in Bala Cynwyd with original 1920s – 1950s masonry should have a Level 2 camera inspection once a year if the fireplace is used regularly, or once every two years if it is occasional. The reason is not creosote buildup. It is the soft local brick and the crown-and-flashing failures at the roofline that show up on these homes, and a Level 2 inspection catches those before water has a chance to rot the smoke chamber. If you light fires only a few times per winter, the inspection can wait, but do not go more than two years without a camera up the flue. Call (830) 251-4560 to schedule one and get a written report with photos.
You need a camera inspection if the chimney is original to a pre-1960 Bala Cynwyd house or if you have had any water staining, animal noise, or a damper that sticks. A visual check from the firebox cannot see cracks in the flue liner, cannot see a glazed third-degree creosote layer hiding behind a first-degree layer, and cannot see crown damage from below. The camera show you the inside of the flue inch by inch, and we hand you the photo report so you are looking at the same evidence we are. If the chimney looks clean on camera and the masonry is sound, we will tell you that too, and you do not need to pay for a sweep you do not need.
It means the concrete or mortar cap on top of your chimney is cracking and flaking away, which lets rain run into the masonry and eventually into the flue and smoke chamber. On Bala Cynwyd homes with the original soft brick, a spalling crown is often the first sign that water has been soaking the chimney for years. The fix is to recast the crown with a proper sloped shape and a drip edge, not to patch it with caulk. Crown recasting around here runs $550 – $1,100, and it is a repair you can schedule before the next heavy rain; it rarely requires the fireplace to be shut down.
Yes, and on a Bala Cynwyd slate-roof home a properly fitted cap is the single most cost-effective repair you can make. It keeps rain, snowmelt, and animals out of the flue, and it prevents the freeze-thaw damage that spalls the soft brick below. The key is that the cap has to be mounted correctly so it does not crack the surrounding slate, which is why we use a proper slate-compatible mounting and flashing rather than a one-size-fits-all bracket. A standard cap replacement in this area runs $185 – $425 installed, and the quote is written before we book.
No, a glazed third-degree creosote layer cannot be removed with a standard wire brush. It is hardened, shiny, and bonded to the flue liner, and brushing it only polishes the surface while leaving the fire risk intact. In Bala Cynwyd we occasionally find this on homes where the fireplace gets used heavily during winter and the liner was last swept years ago. Removal requires chemical treatments or rotary cleaning tools, which is more involved than a standard sweep, and the written price will reflect that before we start. If you have a glazed flue, the chimney is not safe to use until it is addressed; call (830) 251-4560 and we will scope it and give you a straight answer on what removal will take.
One more thing worth knowing. A crew was called to a stone colonial off Llandrillo Road in Bala Cynwyd where the homeowner had water staining on the firebox side wall and a damper that stuck halfway. We ran a Level 2 inspection, put a camera up the flue liner, and found the chimney crown cracked and the flashing pulled away from the slate, not a creosote problem at all. We reset the flashing, recast the crown, replaced the damper, and left the firebox intact; the homeowner got a photo report showing every step, and the price matched the flat quote agreed before we booked. That is how every Bala Cynwyd job goes: evidence first, written price second, repair third.
