Chimney Cap Installation

Chimney Cap Installation is the process of fitting a protective cover over the top of your flue to keep rain, birds, squirrels, leaves, and debris from getting inside. In Miami, we install caps on chimneys year-round because our wet season turns an uncovered flue into a water inlet, and our trees keep squirrels busy looking for nesting spots. A standard chimney cap installation in Miami typically runs $185 to $450 depending on the flue size, cap material, and whether the top of the chimney needs any prep work first. We carry caps from Copperfield and Gelco, both built to handle coastal weather without rusting through in three years.

When a New Cap Makes Sense

An uncovered flue in Coral Gables or South Miami is an open invitation to water damage and animal problems. We see chimneys where missing caps led straight to rusted dampers, stained ceilings, and nests packed into the smoke chamber. If your chimney has no cap, or the existing one is bent, rusted through, or sized wrong, installation is a same-visit fix.

What We Check Before Installing

We measure the flue opening exactly, because a cap that doesn’t fit correctly either blocks draft or leaves gaps for rain. We also inspect the crown and top courses of brick while we’re up there. If the surface the cap mounts to is failing, we’ll tell you before we install anything and put the fix in writing.

Chimney Cap Replacement

Chimney Cap Replacement means removing a damaged or undersized cap and installing a new one that fits the flue correctly. You need replacement when the existing cap has rusted through, lost its mesh, pulled loose in a storm, or was installed wrong in the first place, which we see often in older Miami homes where a previous owner bought whatever cap was on sale. Chimney cap replacement in Miami runs $195 to $420, and the price depends on flue dimensions and whether the old cap’s mounting hardware has damaged the crown underneath. We quote it in writing before we start.

Rust and Salt Air Damage

Miami’s salt air and summer storms are hard on metal. We’ve replaced caps in Fountainebleau and North Bay Village that looked fine from the ground but had rusted mesh panels and pitted tops once we got up there. Once the mesh goes, birds get in. Once the top rusts through, water gets in. Replacement is cheaper than repairing the water damage that follows.

Correct Fit Matters

A cap that’s too small chokes the draft and forces smoke back into the house. One that’s too large leaves gaps for rain. We size every replacement to the actual flue opening, not the outside of the chimney, and we verify the draft after installation so you’re not guessing whether smoke will vent properly.

Chimney Liner Installation

Chimney Liner Installation is the process of fitting a new flue liner inside your chimney to channel smoke, heat, and combustion gases safely out of the house. You need a liner installed when the existing clay liner has cracked, spalled, or separated at the joints, which is common in Miami homes built before the 1980s. Chimney liner installation in Miami typically runs $1,800 to $2,800 for a standard single-story home, depending on the flue dimensions and the liner material specified. We install DuraFlex stainless steel liners and HeatShield resurfacing systems, both specified by the actual job, not by margin.

DuraFlex Stainless Steel Liners

DuraFlex is a flexible stainless steel liner system that we install when the existing flue is too far gone to repair with resurfacing. It’s the right call when clay tiles are missing, cracked, or shifted out of place. The liner gets sized to the appliance, insulated where code requires, and connected correctly at the top and bottom.

HeatShield Ceramic Resurfacing

HeatShield is a ceramic sealant system that restores a damaged flue without tearing out the old tiles. It works when the structural damage is limited to cracked joints and minor spalling. After application, we camera-verify the full flue so you can see the finished surface with your own eyes before we call the job done.

Chimney Flashing Repair

Chimney Flashing Repair is the process of fixing or replacing the metal flashing that seals the joint where the chimney meets the roof. In Miami, this is one of the repairs we do most often because our heavy rain and wind load puts constant stress on flashing seams, and once a seam opens, water runs straight down into the attic. Chimney flashing repair in Miami runs $450 to $950 depending on how much of the flashing has failed and whether the roof deck has absorbed moisture. We replace flashing in full sections when it’s compromised, never just caulk over the problem.

Leaks Don’t Fix Themselves

Water entering at the flashing joint shows up as stained ceilings, peeling paint near the chimney, or damp insulation in the attic. By the time you see the stain, the leak has usually been active for weeks. We trace the water path, identify the exact entry point, and quote the repair in writing before touching anything.

Proper Sealing and Step Flashing

Good flashing work depends on correct layering. Step flashing woven into the shingles, counter flashing cut into the masonry, and a properly sealed base. We don’t apply a bead of caulk and call it fixed. We remove the failed sections, replace what’s needed, and verify the seal before we come down.

Chimney Crown Repair

Chimney Crown Repair means restoring or rebuilding the concrete or mortar crown that caps the top of the chimney structure and sheds water away from the flue. Miami crowns fail faster than inland crowns because the constant wet-dry cycle works small cracks open into wide gaps. Chimney crown repair in Miami runs $350 to $700 for a full crack repair and recoat, and up to $1,100 if sections need rebuilding. We use a flexible crown sealant that moves with Miami’s temperature swings instead of cracking again in six months.

Hairline Cracks Become Big Problems

A hairline crack in the crown lets water into the brick and mortar below. In Miami Gardens and Opa-locka, we see crowns that were ignored until the top three courses of brick were spalling and the damper below was rusted. Small crack, big repair bill. Catching it early keeps the fix small.

Rebuilding vs. Resealing

We reseal crowns with our flexible sealant when the concrete is still structurally sound and the damage is limited to cracking. If the crown has crumbled, spalled, or sloped inward, we rebuild it with a proper overhang and drip edge so water sheds away from the chimney body. Either way, the price is in writing before we start.

Chimney Repair Companies

Chimney Repair Companies in Miami range from independent sweeps operating out of a truck to multi-state franchises with marketing budgets bigger than their training programs. What separates them is what they put in writing. Flint Chimney Co Miami has operated since 2002 under The Garrison Standard, which requires a written price before any work starts and a one-year written guarantee on every repair. If you’re comparing chimney repair companies, ask each one what their guarantee covers, for how long, and what happens if the fix fails. We answer those questions in plain English before you ever sign anything.

What to Ask Before Hiring

Ask if the price is written before work begins. Ask if the technicians are background-checked and uniformed. Ask what brands of materials they install and why. If a company won’t put their price in writing before the first tool comes off the truck, call someone else. We’ve had customers in South Miami and Doral tell us stories about a $99 sweep turning into a $1,500 upsell at the door. That doesn’t happen here because the price is set before work starts.

Why We Lead with the Guarantee

The 365-Day Done Right Promise isn’t a sales line. It’s a written commitment that says if a covered repair fails within one year, we return at no charge and make it right. Hank Delano built the Miami operation on that promise, and it’s the first thing every customer gets after the repair is complete. That’s the standard. The Garrison Standard.

Chimney Masonry Repair

Chimney Masonry Repair covers the brick and mortar work that keeps your chimney standing straight and sealed against Miami’s weather. We repoint failing mortar joints, replace spalled brick, rebuild top sections where water has done structural damage, and reset loose brick before it becomes a falling hazard. Chimney masonry repair in Miami runs $800 to $2,000 depending on how many courses of brick are affected and whether we’re repointing a few joints or rebuilding a section. Every masonry job starts with a written price and ends with a written guarantee.

Miami’s Mortar Problem

Humidity and salt air eat away at mortar faster than most homeowners realize. We see chimneys in Olympia Heights and Sunny Isles Beach where the mortar has turned to sand in spots, leaving brick moving under hand pressure. Once mortar fails, water gets behind the brick, and the damage accelerates. Repointing the affected joints stops the cycle.

Brick Replacement and Structural Work

Spalled brick faces, brick that’s cracked through, brick that’s moved out of plane, these are structural warning signs we address directly. We remove the failed brick, match the replacement as closely as possible, and relay it with the right mortar mix. For larger structural concerns, we tell you plainly what’s dangerous, what can wait, and what the numbers are on each path.

Brands We Service

We install and work with professional-grade chimney products from the brands we trust, and we specify them by job, not by margin. That means the brand name on your invoice is there because the job called for it, not because we made a nickel more selling it. We work regularly with DuraFlex stainless steel liner systems, HeatShield ceramic resurfacing systems, Copperfield caps, and Gelco caps and chase covers.

DuraFlex liners give us a flexible stainless steel solution for flues where the original clay has failed beyond resurfacing. HeatShield restores flues with cracked joints and minor spalling without tearing out the old structure. Copperfield and Gelco make caps and covers that hold up to coastal weather better than big-box generics. Whether your chimney needs a specific brand or you’re not sure what it needs, we’ll figure out the right fit and put it in writing before any work starts.

Signs You Need a Pro Right Now

• Water stains on the ceiling near the chimney. Water is getting past the flashing, crown, or brick, and it’s been doing it long enough to reach your ceiling. By now the attic sheathing or drywall has already absorbed moisture. Every week this waits, the repair scope grows.
• Rust on the damper or smoke chamber surfaces. Rust inside the chimney means water has been entering from above for a while. The damper rusts first because it’s the first metal surface the water hits. If you see rust during a sweep or inspection, you need the water entry point found and sealed.
• Spalling brick or crumbling mortar on the chimney exterior. Brick faces falling away or mortar turning to powder means the structural surface is failing. Loose brick at height is a safety risk, and the exposed interior brick will fail faster. This is masonry repair territory, and it won’t wait until next dry season.
• Animal sounds or nest material in the flue. Squirrels, birds, and raccoons get in through missing or damaged caps. Nest material in the flue is a fire risk the first time you light a fire, and animals can’t be safely removed until the entry point is capped and sealed.
• Smoke backing up into the house. If smoke comes back into the room instead of going up the flue, you have a draft problem caused by a blocked flue, a collapsed liner, or a cap that’s too small. This is a carbon monoxide risk if you keep burning. Stop using the fireplace and get it inspected.

Our Process, Step by Step

1. 1
   Written quote before any work starts. We inspect the chimney, identify the problem, and put the repair scope and price in writing. You approve the number before a single tool comes off the truck. The invoice matches the quote, always.
2. 2
   Site protection and prep. We lay down drop cloths, protect the work area, and set up our equipment before touching the chimney. Our technicians are background-checked and uniformed, so you know exactly who’s in your home and why they’re there.
3. 3
   Camera inspection and photo documentation. For liner, flashing, and internal repairs, we run a camera up the flue before and after the work. You see the actual damage with your own eyes, then you see the finished result. No guesswork, no trust-me pricing.
4. 4
   The repair itself, built to last. We use brand-specified materials, DuraFlex, HeatShield, Copperfield, Gelco, whatever the job calls for, and we follow manufacturer installation standards. The repair is completed in a single visit for most jobs.
5. 5
   Written guarantee and final walk-through. Every repair gets the 365-Day Done Right Promise in writing, valid for one year from the service date. We review what was done, what the guarantee covers, and what to watch for going forward. If a covered repair fails, we return at no charge.
