We’ve been driving out to Keystone since the early 1980s, back when much of this area was still dirt roads threading through oak hammocks. The homes we service here aren’t like the tract houses closer to Tampa. They’re spread across acreage off Gunn Highway and Van Dyke Road, with chimneys that may have been installed as afterthoughts during the building boom of the 1980s and 1990s. That distance from the city center is exactly why response time matters. Our technicians know the back routes past Lake Keystone, and we schedule Keystone calls with realistic drive-time built in. We’ll be there when we say.
Why Hearthstone Chimney Co. Is Keystone’s Preferred Chimney Cap & Crown Company
Keystone homeowners don’t call a chimney company twice a year. They call once, when something has gone wrong, and they need it handled without drama. We’ve earned that trust over 42 years by treating every Keystone job as if we’ll be back next decade to service it again.
Our reputation here is built on showing up. Not “sometime Tuesday,” but a specific window, confirmed by text, with a uniformed technician who has already reviewed satellite imagery of your roofline. Most Keystone jobs finish in a single visit because our trucks carry DuraFlex and Copperfield caps in common sizes, plus crown-coating materials ready to mix.
We document everything. Our Level-2 camera inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown has three hairline cracks and one serious spall, we’ll show you which is which and explain exactly what happens if you wait.
The 90-Day Done Right Promise applies to every Keystone job in writing, no arguing. If the cap leaks or the crown coating fails because we missed something, we come back. That’s the Keystone Standard, and it’s why homeowners off Tarpon Springs Road and along the lake have kept our number posted on their refrigerators for decades.
Our Chimney Cap & Crown Services in Keystone
Cap Installation
New cap installation in Keystone runs $340-$580 for a standard single-flue stainless steel unit, including measurement, custom fitting, and secure mounting. We size caps to your flue exactly, not close enough. On Keystone’s larger custom homes, we regularly install multi-flue caps spanning three or four flues on a single masonry chase, which runs $620-$950 depending on dimensions. Every installation includes a wildlife screen with proper mesh spacing - tight enough to stop squirrels and raccoons, open enough to maintain draft. Given the nesting pressure on wooded lots near Lake Keystone, this isn’t optional. It’s the reason you called.

Cap Replacement
Replacing a rusted, wind-damaged, or improperly installed cap in Keystone typically costs $280-$520. We see a lot of builder-grade caps out here that lasted maybe five Florida summers before the galvanized coating surrendered to humidity. Our replacement caps use thicker-gauge stainless or copper from Copperfield and Famco, with proper counter-flashing integration into your existing crown. If the crown itself is compromised, we’ll tell you before we remove the old cap, not after. No surprises on the bill.

Crown Repair
Crown repair in Keystone averages $380-$720, depending on whether we’re patching localized spalls or rebuilding the entire concrete wash. Keystone’s elevated humidity near the lake accelerates the freeze-thaw cycling that cracks crowns, even without actual freezing - the daily expansion and contraction of moisture-saturated concrete does similar damage over time. We pour new crowns with a proper drip edge and slope, or apply HeatShield crown coating when the structure beneath is sound. Either way, water sheds away from your flue instead of pooling against it.

Crown Coating
Crown coating with HeatShield or similar professional-grade elastomeric sealant runs $320-$480 in Keystone. This is the right choice when your crown has surface cracking and minor spalling but hasn’t delaminated from the brick course below. We pressure-wash, let it dry thoroughly in this humidity, then apply two coats with embedded mesh for tensile strength. On Keystone homes where the fireplace sees only occasional December use, crown coating can add ten years of protection without the cost of full replacement. We’ll show you the photos and give you the square deal either way.
Our Chimney Cap & Crown team also fabricates custom caps for non-standard flue configurations common in Keystone’s semi-custom builds. If your chimney was designed by an architect who never consulted a sweep, we’ve seen it before and we’ll measure twice.

Trusted Brands We Service in Keystone
We stock caps, crowns, and repair materials from Famco, Copperfield, and DuraFlex - brands that have proven themselves in Florida’s coastal humidity over decades, not seasons. Our Keystone warehouse carries the common sizes and profiles so we’re not ordering special parts while your flue stays open to the weather. For custom work, we fabricate from detailed field measurements, not guesses. The materials arrive when we do, and most jobs finish before we leave.
Common Chimney Cap & Crown Problems We See in Keystone Homes
- Wildlife occupation in uncapped flues. On wooded lots off Gunn Highway and around Lake Keystone, raccoons and squirrels treat an open flue like a pre-built den. We regularly find nesting material packed six feet down, sometimes with active chimney swift colonies that legally cannot be disturbed during breeding season. A proper cap with integrated screen prevents this entirely.
- Crown cracks from humidity cycling. Keystone’s persistent moisture, especially June through September, penetrates porous concrete crowns daily. The expansion and contraction spalls the surface, exposes aggregate, and eventually channels water straight into the chimney structure. We catch this early with camera inspection.
- Builder-grade cap rust and failure. Homes built in the 1980s and 1990s around Cheval and Citrus Park often received the cheapest galvanized cap the contractor could find. After twenty years of Florida rain, they’re rusted through or blown off in a thunderstorm. Replacement with stainless or copper is a permanent fix.
- Efflorescence and biological growth on dormant fireplaces. Keystone fireplaces may sit unused for ten months, letting moisture and mold colonize the firebox. The cap is your first defense; without it, the crown can’t do its job, and the whole system deteriorates from the top down.

FAQs - Chimney Cap & Crown in Keystone
We typically schedule cap and crown repairs in Keystone within 2-4 business days, with emergency same-day service available if water is actively entering your flue or wildlife is trapped inside. Our technicians know the back roads past Lake Keystone and build realistic drive time into every appointment window. Call (844) 803-1545 and a live person will find the next available slot.
Yes, we service the full 33556 ZIP, from the estate lots along Lake Keystone to the semi-rural acreage off Van Dyke Road and the custom homes near Cheval. We’ve worked on chimneys with boat-lift views and chimneys tucked back in oak hammocks with half a mile of dirt driveway. The access type affects scheduling, not whether we’ll come.
We check first, always. Chimney swifts are federally protected, and active nests cannot be disturbed. Our technicians are trained to identify swift occupation by sound, visual inspection, and camera. If we find an active nest, we document it, explain the timeline, and reschedule your cap installation for after the breeding season. A temporary screened exclusion may be possible depending on configuration. This is non-negotiable protocol on every Chimney Cap & Crown in Keystone job.
Material costs are consistent, but Keystone’s larger custom homes often require bigger or multi-flue caps, and the semi-rural location adds modest travel time that we absorb rather than surcharge. In practice, a standard cap replacement in Keystone costs about the same as in Carrollwood or Citrus Park. Custom fabrication for architect-designed chimneys runs higher everywhere. We quote your specific job upfront so you can compare fairly.
Yes, every cap and crown job in Keystone carries our 90-Day Done Right Promise in writing, with no arguing and no paperwork chase. If the cap leaks, the crown coating fails, or any detail of our work is not right, we return and make it right at no charge. We’ve been serving this area for over 42 years, and we plan to be here when your next need arises. That’s why we stand behind it.
Ready to protect your chimney from Keystone’s humidity, wildlife, and weather? Call (844) 803-1545 for a free estimate.
