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 St. Augustine’s Preferred Chimney Repair Company
We’ve been part of the Garrison Partners family since 2002, and the St. Augustine homes we work on have a particular set of problems that we’ve learned to read quickly. Coastal humidity doesn’t just sit on the surface of your chimney. It works into the mortar, the crown, the brick face, and the damper assembly. That means the standard repair list here looks different than it does in Orlando or Tampa, and a company that treats every Florida chimney the same is going to miss things.
Every technician who shows up in St. Augustine is background-checked and in uniform, so you know exactly who’s walking through your door. Every job gets a written price before work starts. 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 phone tree, no callback form. A live person answers our phone 24/7.
Hank Delano runs our team, and the standard he’s set is simple: document the problem on camera, show you the photos, put the repair in writing, and stand behind it. If we can’t show you the problem, we don’t recommend the work.
Chimney Masonry Repair in St. Augustine
Chimney Masonry Repair in St. Augustine is the most common reason homeowners call us after a Level 2 inspection, because the city’s humid coastal air keeps brick and mortar damp for months at a time. That constant moisture accelerates spalling – the crumbling and flaking you see on older brick – and wears down the mortar joints between bricks. Typical masonry repair work here includes Chimney Repair for tuckpointing (removing deteriorated mortar and repacking joints with fresh compound), spalling brick replacement, and crown resurfacing. On most St. Augustine homes, masonry work runs $450 – $1,850 depending on the square footage of damaged face brick and how much of the crown needs rebuilding.
Mortar Repointing and Tuckpointing
When mortar joints start to crumble, water gets behind the brick and does its work from the inside out. We remove the loose material with hand tools and repack those joints with a mortar matched to what’s on the home. In older St. Augustine neighborhoods where brick is soft and aged, we use a softer mortar mix so the repair doesn’t become harder than the brick around it, which would cause new spalling later.
Spalling Brick and Crown Repair
Spalling brick on St. Augustine chimneys usually starts at the top, where the crown has lost its slope and water pools after rain. Once the face of a brick has popped or flaked, the damage is already structural in the sense that water is entering faster than it can evaporate. We’ll replace damaged brick, rebuild or resurface the crown with a proper slope, and often add chimney waterproofing so the repair lasts through the humid season.
Chimney Cap Installation in St. Augustine
Chimney Cap Installation in St. Augustine is the work we recommend most often after an inspection, because a properly fitted cap does three things at once: it keeps rain out of the flue, it stops birds and squirrels from nesting, and it slows the rust that our salt-laden air causes on dampers and flue liners. A stainless cap installed on a standard single-flue St. Augustine chimney typically runs $295 – $475. For larger caps, multi-flue designs, or caps that need custom fitting around historic brick profiles, the range can reach $650.
Stainless Caps for Coastal Air
We use stainless specifically because it resists the chlorides in St. Augustine’s coastal air longer than galvanized. A galvanized cap near the shore can start showing rust within a few seasons. Stainless holds up better, and it pairs well with a waterproofing treatment on the crown below it.
Custom-Fit Caps for Historic Chimneys
Many homes in the St. Augustine historic districts have chimney crowns with irregular profiles and older brickwork that standard caps don’t seat properly on. We measure and fit each cap to the actual flue opening, not the closest stock size, and we document the fit with photos before we leave.
Trusted Brands We Service in St. Augustine
We stock the parts St. Augustine customers actually need from brands we can stand behind, including Gelco crown coats and waterproofing sealants, Olympia Chimney caps and dampers, and Famco flashings. Using professional-grade materials matters here more than it does inland, because the salt air and humidity punish cheap parts in ways that show up within a year or two. We don’t spec products by margin. We spec them by what survives on a coastal chimney.
Common Chimney Repair Problems We See in St. Augustine Homes
- Spalled crowns from constant humidity. Because St. Augustine’s coastal air keeps crown surfaces damp much of the year, the concrete or mortar at the top of the chimney degrades faster than it does in drier parts of Florida. Flaking and cracking at the crown are the first signs, and that’s where water starts entering the chimney stack.
- Rusted dampers that won’t seat or seal. The combination of salt-laden air and humid summers means dampers in St. Augustine homes corrode faster than the same part would inland. A damper that won’t fully close lets conditioned air escape all summer and lets moisture in during storms.
- Unlined or deteriorated flue liners in older homes. Many 1920s-era homes in the historic districts were built with unlined flues or with clay tile liners that have cracked after decades of use. Once the liner fails, the heat and gas have a direct path to the home’s framing, and mortar joints inside the flue can open unnoticed.
- Third-degree creosote from skipped inspections. Because St. Augustine rarely sees hard freezes, homeowners often go years without a sweep, assuming there’s nothing to check. First-degree creosote progresses to a hard, glazed buildup that a standard brush cannot remove, and that becomes a repair job rather than a maintenance visit.
Pricing for Chimney Repair in St. Augustine, FL
A standard chimney cap installation in St. Augustine runs $295 – $475, while masonry repair work like tuckpointing or a partial crown rebuild falls between $450 and $1,850 depending on access and how much material needs replacing. Flue relining (replacing the inner liner that channels smoke safely out of the house) starts at $1,500 and goes up from there based on flue height and liner type. The factors that move your number are access to the chimney, whether the home is in a historic district with stricter material requirements, and the condition of the surrounding masonry. The written price we give you before work starts is the price you pay – nothing moves, and we put that on paper before we pick up a trowel. Call (830) 251-4560 for a free estimate.

FAQs About Chimney Repair in St. Augustine
Yes, and the reason here is the moisture, not the fire. Even if you never light a fire, St. Augustine’s humid coastal air is working on your crown, your damper, and your mortar year-round. An annual inspection catches spalling before it becomes structural and finds rust on dampers before they seize. The inspection also documents liner condition, which matters on older homes where hidden mortar joint failures are common. Call (830) 251-4560 to schedule an inspection with a camera report.
For most St. Augustine homeowners who burn wood regularly during the cooler months, once per year is the honest answer. If you burn soft woods like pine, or if you burn during the humid season when creosote adheres more aggressively, you may need a second sweep. The buildup rate depends on what you burn and how often, but skipping more than two years near the coast is where we start seeing glaze that requires chemical treatment rather than a standard brushing.
Third-degree creosote is a hard, glazed tar-like layer that has baked onto the flue walls and cannot be removed with a brush alone. It becomes a chimney repair job because the flue needs chemical treatment or mechanical removal with specialized tools, and in serious cases, a liner replacement becomes the honest recommendation. It also increases the chimney fire risk significantly. If a previous inspection found heavy buildup, call (830) 251-4560 and we’ll show you the photos before any work is proposed.
It is urgent in the sense that it will not get better on its own, and in St. Augustine’s humidity, a spalled crown lets water into the chimney stack nearly every week. The damage compounds: water gets behind the brick, the brick spalls, and the crown eventually needs a full rebuild rather than a resurface. Acting when you first notice the crumbling typically means a crown coat like Gelco and maybe minor tuckpointing, which is far less expensive than waiting for a rebuild.
You can install a cap on a historic St. Augustine chimney without damaging the brick, yes, but it requires custom measurement and a cap that seats properly on the existing crown profile rather than clamping to rough brick. We measure each flue opening on site, account for irregular crown shapes, and install with a method that does not require drilling into historic masonry. The same applies to waterproofing – we use a breathable sealant designed to shed water without trapping moisture inside older brick.
