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.

Chimney repair in Charleston, SC most often comes down to water damage, and around here that means salt, storms, and old masonry. We serve every part of Charleston, from the historic homes on the peninsula grid to newer construction in West Ashley and Daniel Island.

Why Flint Chimney Sweep Is Charleston’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. We bring The Garrison Standard to every job: written pricing, documented scope, and a guarantee you can hold in your hand. Charleston homeowners tell us the same thing over and over. They want a crew that shows up, does what they said, and stands behind the repair. That is the whole job.
Every technician who comes to your door in Charleston is background-checked and uniformed. You know exactly who is walking through the door. And when you call our number, a live person picks up. No voicemail tree, no callback form, no waiting until Monday. If you live in Mount Pleasant, James Island, or out toward Johns Island, the process is the same: book the appointment, get the written price, approve the work, done.
We work with professional-grade chimney materials, including Olympia Chimney, Famco, and Copperfield. We specify the product by the job, not by the margin. That means a liner reline gets the liner material that matches the appliance and the chimney, not whatever is sitting on the truck.
Chimney Liner Installation in Charleston
Chimney Liner Installation in Charleston is one of the most common repairs we do, because so many older homes on the peninsula and in neighborhoods like Wagener Terrace and Riverland Terrace were built without modern flue liners. A flue liner is the inner channel that carries smoke and heat safely from the firebox to the top of the chimney. Without it, heat and carbon monoxide can reach nearby framing that was never built to today’s clearances. That is a genuine safety issue, not a scare tactic.
In Charleston, a standard stainless steel liner installation for a masonry chimney typically runs $1,800 to $3,400 depending on the height of the flue, access, and whether the old terra cotta liner needs to be broken out first. We use DuraFlex and Olympia Chimney liner systems, both built for coastal conditions. A new liner also matters if you are switching to a gas insert or upgrading an older open fireplace.
When a Liner Is Required
We recommend a liner when the existing flue is cracked, spalling, or missing entirely. Our camera inspection shows the exact condition before any work is quoted. If the liner has failed, the repair is not optional. The chimney cannot perform its job without a continuous, sealed pathway for exhaust.
What the Install Involves
We size the liner to the appliance, drop it in from the top, and insulate where the code requires it. The job usually takes one day for a single-story chimney in Charleston. You get a written warranty on the liner and the workmanship, valid for one full year under the 365-Day Done Right Promise.
Chimney Flashing Repair in Charleston
Chimney Flashing Repair in Charleston gets called out most often after summer thunderstorms and hurricane-season wind-driven rain. Flashing is the metal seal where the chimney meets the roofline. When it fails, water travels down the chimney chase, into the attic, and along the ceiling. In Charleston’s salt air, flashing rusts faster than it does inland. A repair that might last 20 years in Columbia can fail in half that time here.
Typical flashing repair in Charleston runs $450 to $1,200 depending on how much flashing needs replacing, whether the roofline is steep, and what material is used. We work with Copperfield flashing products and fabricate on-site for a clean fit. Copper flashing holds up better against salt and storm-driven rain, and it is what we recommend for most Charleston homes.
How We Find the Leak
We do not guess. We inspect the flashing, the crown, and the masonry with a camera, then document it all with a photo report. You see what we see. If the flashing is intact and the leak is coming from a cracked crown or a porous brick face, we tell you that. No upsell.
Storm-Damage Checks
After a big blow, worth checking the flashing before the next rain. Lifted flashing, missing counter-flashing, or separated laps let water in fast. We do free estimates on flashing work anywhere in the Charleston area, including West Ashley and North Charleston.
Trusted Brands We Service in Charleston
We stock and install professional-grade chimney products that hold up in Charleston’s coastal climate. That includes DuraFlex liners, Olympia Chimney caps and dampers, Famco flashings, and Copperfield copper products. When a Charleston homeowner needs a part, we typically have it on the truck or can source it quickly, because we maintain local parts access for the Lowcountry market. Using named brands means you can verify exactly what you are getting before you sign a work order. We put the part names in writing, alongside the labor and the guarantee.
Common Chimney Repair Problems We See in Charleston Homes
- Spalling brick and rusted dampers from coastal moisture. Salt-laden air and storm-driven rain push moisture into the chimney crown and brick face. In Charleston, it is common to see spalling on a 1980s chimney that would still look fine inland. Repointing and crown sealing address the damage before the structure fails.
- Unlined flues in older peninsula homes. Many pre-War homes in neighborhoods like Cannonborough and Elliotborough were built before modern liner standards. If the flue has no liner, heat and carbon monoxide can move through cracks in the old brick mortar joints into living space. A liner installation is the permanent fix.
- Creosote glazing after long gaps between burns. Charleston has a mild burn season. Long stretches without a fire let first-degree creosote harden into a glassy glaze that a routine brush pass will not remove. A chemical treatment or a mechanical rotary clean is sometimes required alongside the sweep.
- Animal nesting in the flue during off-seasons. Squirrels, birds, and raccoons find Charleston chimneys easy spring and summer housing. A properly fitted cap with mesh sides prevents most of it, but if nesting has already occurred, we remove it and then inspect the flue for blockage and fire damage.
Pricing for Chimney Repair in Charleston, SC
Here are honest numbers for the Charleston market. A basic chimney crown seal runs $450 to $900. Flashing repair runs $450 to $1,200. A full stainless liner installation runs $1,800 to $3,400.

FAQs About Chimney Repair in Charleston
Once a year. NFPA 211 calls for annual inspection regardless of how many fires you light. Charleston’s humid, salt-heavy air rusts dampers and breaks down mortar even in fireplaces that sit unused all season. A Level 1 inspection costs less than the repair you skip by catching moisture early. Book a Chimney Inspection in Charleston by calling (830) 251-4560.
A Level 2 inspection adds a camera scan of the entire flue interior. You need it when you buy a home, after a storm or chimney fire, or when the chimney has not been used in years. In Charleston, we recommend Level 2 for any pre-War brick chimney that has never had a documented liner inspection. The camera shows cracks, gaps, and creosote buildup you cannot see from the top or the firebox.
Third-degree creosote looks like a black glassy glaze on the flue walls. A brush alone will not remove it, and continued burning creates real chimney fire risk. The only way to know is a camera inspection. If we find glaze, we recommend a rotary clean or chemical treatment before you burn again. Do not wait. Chimney fires in Charleston homes happen in chimneys people thought were fine.
Depends on the rust damage. A rusted damper plate can sometimes be cleaned and lubricated, but if the frame itself is corroded, replacement is the only safe fix. A damper that will not fully open or close affects draft and can push carbon monoxide back into the house. Our tech will show you the condition on camera, then quote either the repair or the replacement with a flat price before work begins.
Yes. Flashing repair and crown sealing are two of our most common Charleston calls after hurricane-season rain. We schedule the work for the next available appointment, not same-day, because storm-related calls come in fast. You get a written estimate first, and the repair carries the full one-year guarantee. Call (830) 251-4560 and we will get you on the schedule.
