Fast, Reliable Chimney Inspection Across St. Johns
A chimney inspection in St. Johns typically costs between $189 and $649 depending on the level and access involved, and most inspections are completed the same week we book them. Salt-laden air from the Atlantic makes inspection here different from inland Florida, and we’ll show you exactly what we find with camera footage before anything is recommended. Call (904) 453-7823 to schedule yours.
Our Chimney Inspection team serves every corner of St. Johns, from Durbin Crossing to Julington Creek Plantation, with technicians who know what coastal humidity does to metal flue components. We don’t guess. We run a camera up the flue and you see the same feed we do.
Why Alcott Chimney Jacksonville Is St. Johns’s Preferred Chimney Inspection Company
Ruben Castellano has built Alcott Chimney Sweep around a simple idea: a homeowner should never wonder who’s showing up at the door. Every technician we send to St. Johns homes has passed a background check and identity verification through the Threshold Standard, and you’ll receive their name and photo before the visit. Not at the door. Before the visit.
We’ve served Florida homeowners since 2002, and St. Johns keeps us busy for one reason that surprises people: new construction. Homeowners in Durbin Crossing and Julington Creek Plantation often assume a prefab fireplace means no maintenance. That assumption is exactly what our camera inspections correct. We also answer the phone with a live person at any hour, because a smoky fireplace at 11 p.m. in St. Johns deserves an answer, not a voicemail.
Every quote is written before we start work. Every repair carries a written guarantee, and if that repair fails within the coverage period, the return visit is free. We call it the 365-Day Done Right Promise, and it’s included on every St. Johns job. No upsell. No fine print.

Chimney Fire in St. Johns
A chimney fire in St. Johns is the event we’re trying to prevent, and our Level 2 inspections are the tool that stops it before it starts. What you need to know: third-degree creosote, the tar-like glaze that forms when salt-driven moisture mixes with wood exhaust, is the leading cause of chimney fires in coastal Florida. It builds up faster here than in drier climates, and it burns at temperatures that can crack flue tiles and spread to framing.
What We Check for Fire Risk
During every St. Johns inspection, we look for creosote thickness, flue obstructions, and compromised components. Salt air corrodes galvanized chimney caps faster than most homeowners expect, and once a cap rusts through, rain gets in. Wet creosote then hardens into that tar glaze we mentioned. We measure it, photograph it, and tell you plainly whether your fireplace is safe to burn.
When to Act
If you hear a roar from the flue, see heavy dark smoke, or smell hot metal, that’s a fire in progress. Call 911. Once it’s out, call (904) 453-7823 for a Level 2 inspection before burning again. We’ll document the damage and quote repairs honestly. Many St. Johns homeowners catch the corrosion early enough that repair is a few hundred dollars, not a full rebuild.
Level 2 Chimney Inspection in St. Johns
A Level 2 chimney inspection in St. Johns is what we recommend after any property transfer, any chimney fire, or any significant weather event like a tropical storm. The inspection uses a camera to examine the entire flue interior, all accessible firebox and damper components, and the exterior cap, crown, and flashing. It costs more than a Level 1 visual check, typically $349 – $649 in St. Johns, because it goes where your eyes can’t.
Camera Inspection for St. Johns Real Estate
St. Johns real estate closings frequently require a Level 2 inspection, and we handle them for buyers, sellers, and agents across the county. The camera shows exactly what the flue looks like inside, which matters when a home in Julington Creek Plantation has had years of intermittent use. We provide photos and a written report you can hand to the other party or your lender.
The Coastal Wear We Watch For
In St. Johns, a Level 2 inspection is the only way to see pitting at the top edge of a stainless liner, rusted flashing under the shingles, or hairline cracks in a prefab firebox joint. These are salt-air failure points, and they show up years earlier in St. Johns than in inland Jacksonville. Catching them with a camera now costs less than the liner replacement they lead to later.
Trusted Brands We Service in St. Johns
We work on factory-built and masonry systems made by Gelco, Olympia Chimney, and Copperfield, among others. Chances are the prefab fireplace in your St. Johns home came from one of these manufacturers, and we know their specs. DurFlex liner systems and HeatShield resurfacing products are what we turn to when corrosion has gone too far for a cap-and-flashing fix, and we keep commonly needed St. Johns parts in our trucks so a simple inspection doesn’t turn into a two-week wait for delivery.

AfterCommon Chimney Inspection Problems We See in St. Johns Homes
- Corroded caps and crowns: Salt air in St. Johns eats through galvanized chimney caps in as little as five to seven years. A rusted cap lets rain into the flue, where it mixes with creosote and makes a mess that clings to the liner.
- Bird and wasp nests in idle flues: Mild St. Johns winters mean fireplaces go unused for months. In neighborhoods like Julington Creek Plantation, we pull bird nests, squirrel hoards, and wasp hives out of flues every fall before fireplace season begins.
- Rusted flashing at the roofline: The humid, salty air doesn’t just attack caps. It rusts the metal flashing where the chimney meets the roof, and a small rust hole becomes a rainwater leak inside your ceiling. Camera inspection catches it before the drywall does.
- Spalling brick and cracked mortar on older homes: St. Johns still has a good number of older brick homes, particularly in the established neighborhoods west of I-95. Salt-driven moisture gets into the masonry, freezes in rare cold snaps, and pops the face off bricks over time. Our inspection flags these before pieces start falling.
Pricing for Chimney Inspection in St. Johns, FL
Expect these ranges for a chimney inspection in St. Johns:
- Level 1 visual inspection: $189 – $289. We look at the readily accessible portions of the chimney, firebox, and damper. No camera.
- Level 2 camera inspection: $349 – $649. Includes full video scan of the flue interior, firebox, smoke chamber, and exterior components. This is what we recommend for St. Johns homes because salt corrosion happens where you can’t see.
- Level 3 inspection: $800 – $2,500. Involves partial demolition to access hidden components. Rarely needed in St. Johns, but we’ll tell you plainly if it is.
What affects your price: roof height and pitch, flue height, the number of flues, and whether we need to pull a corroded cap just to get the camera in. You get a written quote before we start, and you pay exactly what that quote says. Call (904) 453-7823 for a free estimate over the phone.

FAQs About Chimney Inspection in St. Johns
Yes, and faster than you’d expect. A galvanized chimney cap in St. Johns can fail in five to seven years because of salt-laden Atlantic air. In Durbin Crossing, our tech pulled a corroded galvanized cap off a prefab flue and found the stainless liner’s top edge was already pitting, while the roofline flashing had rusted through. We replaced the cap with stainless, sealed the flashing, and ran a Level 2 camera inspection to confirm the firebox and draft were still sound. Call (904) 453-7823 if your cap is starting to look orange or flaky.
Yes, and in St. Johns you need it sooner than the manufacturer’s interval may suggest. Direct-vent gas fireplaces still have exterior termination caps and venting that gets hit with salt-laden air, and birds love building in those vents during the months the fireplace sits unused. A Level 1 inspection runs $189 – $289, and it’s the cheapest way to confirm your five-year-old venting hasn’t already started corroding. Worth it every other year at minimum.
The cap almost always goes first, because it’s the thinnest galvanized piece and takes the most direct salt exposure. Flashing runs a close second, rusting at the roofline where water pools. The prefab chimney’s metal crown is usually last because it’s heavier gauge and better coated. In our St. Johns inspections, caps fail around year five to seven, flashing by year eight to ten, and crowns usually last twelve or more. We check all three on every visit.
Every two to three years for a factory-built fireplace in Julington Creek Plantation, or sooner if you burn frequently, hear chimney noises, or see rust streaking on the cap. Annual Level 1 checks catch buildup. But a Level 2 camera inspection is the only way to see what salt air has done inside the flue, and in this part of St. Johns, we see enough corrosion to justify it on a two-to-three-year cycle. If it’s been more than that, call (904) 453-7823 for a free phone estimate and we’ll book the camera scan.
Yes. Salt air corrodes the cap and flashing, water enters the flue, and that water mixes with whatever creosote you do produce, making it stickier and harder to remove. The result is a damp, tar-like glaze that hardens into third-degree creosote over time. Even occasional burners in St. Johns develop this faster than inland homeowners. An annual inspection before burning season is the cheapest control.
If your fireplace hasn’t been inspected this year, call (904) 453-7823. Ruben and the team at Alcott Chimney sweeps and inspects fireplaces across St. Johns, FL, and we’ll show you the camera footage so you know exactly what’s going on up there.
