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.
