Fast, Reliable Chimney Repair Across St. Johns
Chimney repair in St. Johns typically runs $250-$1,800 depending on whether you need Chimney Cleaning & Sweep - St. Johns or a full chimney rebuild, and most jobs we can schedule within 48 hours. We’re familiar with the specific construction patterns out here - the master-planned communities along CR 210 and the St. Johns River corridor - and we carry the parts to fix most problems in a single visit.
St. Johns isn’t Jacksonville, and it isn’t historic St. Augustine. The homes here are newer, built fast during the 2000s boom, and the chimneys reflect that. Our technicians have worked in Julington Creek Plantation, Durbin Crossing, and RiverTown long enough to know which builder packages fail where, and why. When you call (844) 803-1545, a live person answers - day, night, weekend - and we’ll give you a real arrival window, not a four-hour guess.
Why Hearthstone Chimney Co. Is St. Johns’s Preferred Chimney Repair Company
We’ve been serving Northeast Florida for over 42 years, and the St. Johns growth corridor has been our bread and butter since the first phase of Julington Creek broke ground. That longevity matters here. We’ve watched the same galvanized chase covers rust through across entire subdivisions, and we know which production builders used which specs. When a homeowner in Durbin Crossing calls with water stains on their drywall, we often know the chase pan model before we arrive.
Our customers in St. Johns mention the same things in their feedback: we show up when we say, we explain what we found in plain English, and we leave photos they can actually see. The 90-Day Done Right Promise isn’t a slogan here - it’s in writing, with no arguing. If something isn’t right, we come back and make it right. That’s how you stay in business for four decades in the same towns.
Response time to St. Johns is typically same-day or next-day, depending on call volume. We’re not dispatching from downtown Jacksonville and hoping to beat bridge traffic. Our routes are planned around St. Johns County’s road network, and we know the difference between a RiverTown address off SR 13 and a Julington Creek home near Race Track Road. That local routing saves you waiting.
Our Chimney Repair Services in St. Johns
Mortar Repointing
True masonry chimneys are rare in St. Johns, but they exist - mostly in the older fringe areas near the river or in custom builds that predated the master-planned boom. Where we do find them, the mortar joints suffer from the same humidity cycling that affects the rest of Northeast Florida: wet winters, dry spells, expansion, contraction. We grind out failed joints to proper depth and repoint with color-matched mortar rated for our climate. In St. Johns, we typically quote mortar repointing at $450-$850 for accessible sections.
Spalling Brick Repair
Spalling - brick faces flaking off from freeze-thaw or moisture intrusion - shows up in St. Johns on chimneys that were built with softer brick or sealed improperly. The damage usually starts at the crown and works down. We remove spalled units, install matching brick where possible, and address the water source so it doesn’t repeat. For St. Johns homes with genuine masonry, spalling repair runs $350-$700 per affected area, with full rebuilds starting around $1,200 if the structural course is compromised.
Chimney Waterproofing
This is where St. Johns homeowners should pay close attention. With prefabricated metal-chase fireplaces dominating the market here, “waterproofing” often means sealing the chase top, replacing the chase cover with a proper stainless or copper model, and ensuring the crown or chase pan sheds water correctly. The original builder-grade galvanized covers in communities like RiverTown and Durbin Crossing are reaching end of life simultaneously. We apply professional-grade water repellents to masonry where found, but for most St. Johns homes, the real waterproofing work is metal: new chase covers, proper flashing integration, and sealing the chase structure against wind-driven rain. Typical waterproofing service in St. Johns: $400-$950.
Flashing Repair
Roof-to-chimney flashing fails in St. Johns for two predictable reasons: the step flashing was never integrated properly during fast production construction, or the sealant has aged out in our high-UV environment. We see this constantly in the 2005-2015 build era throughout Julington Creek Plantation. Our flashing repair removes the damaged material, installs new step and counter flashing where appropriate, and seals with compounds rated for Florida’s thermal expansion. Most flashing repairs in St. Johns run $350-$650, with full replacement at $700-$1,100 if the roof interface is complex.
Our Chimney Repair team also handles full chimney rebuilding and tuckpointing when the damage has progressed beyond spot repair. And if your issue turns out to be chase cover or crown related, we coordinate with our Chimney Cap & Crown in St. Johns specialists to handle it without bringing out a second crew.

Trusted Brands We Service in St. Johns
We don’t use builder-grade substitutes, and we don’t make you wait three weeks for a part. Our trucks carry DuraFlex liner components, Famco termination caps, and Copperfield masonry supplies because we’ve learned which products survive in St. Johns’s humidity. When your chase cover has rusted through or your flue needs Chimney Liner & Rebuild in St. Johns, we install what we’d put in our own homes - professional-grade materials with documented ratings, not whatever was cheapest at the supply house that morning. That inventory on the truck means most St. Johns repairs finish in one visit, and you’re not paying for a return trip.
Common Chimney Repair Problems We See in St. Johns Homes
- Galvanized chase covers rusted through from the inside out. The humid microclimate inside an infrequently used metal chase is aggressive, and homeowners in early Julington Creek Plantation phases discover this only after water damage appears on interior walls near the firebox surround. We replace these with stainless steel or copper models that won’t repeat the failure.
- Improperly sealed chase tops allowing wildlife entry. Squirrels and birds find gaps in aging sealant or corroded mesh, and St. Johns’s river-corridor habitat means plenty of wildlife pressure. A nesting situation can block the flue entirely and create real hazard.
- Flashing separation at roofline on homes built 2005-2015. Fast production schedules in communities like Durbin Crossing and RiverTown meant flashing was sometimes tacked in rather than properly integrated. Five to ten years of thermal cycling opens these gaps wide enough for measurable water intrusion.
- First-stage creosote buildup from low-temperature burns. St. Johns homeowners who fire the fireplace only a handful of times per season tend to build small, smoldering fires - the kind that deposit sticky, ignitable creosote rather than burning it off. This compounds any existing draft or venting problem.
