Chimney Cap Installation

Chimney Cap Installation means fitting a protective metal cover over the flue opening that keeps rain, birds, squirrels, and leaves out of your chimney. Houston homeowners need caps more than most because our spring storms dump inches of water into open flues, which accelerates liner rust and can leave standing water in your smoke chamber. Flint Chimney Co Houston installs stainless steel and copper caps from Gelco and Olympia Chimney, and a standard cap installation in Houston typically runs $325 to $650 including the cap, mounting hardware, and sealing.

Why an Open Flue is a Houston Problem

In neighborhoods like Cinco Ranch and Deer Park, we regularly pull squirrel nests and rotted leaves out of uncapped chimneys during fall inspections. The humidity inside the flue makes whatever falls in decompose fast, and the smell works its way into the house when the air conditioning runs. A $400 cap is cheaper than a $2,000 liner, and it stops the problem at the source.

What Installation Actually Involves

We measure the flue, match the cap to your tile or liner size, fasten it with stainless hardware, and seal the joints with high-temperature caulk rated for chimney use. The written quote includes everything, and you’ll see the cap installed and photographed before we leave.

Chimney Cap Replacement

Chimney Cap Replacement is what happens when the original cap is rusted through, bent beyond repair, or missing entirely after a Houston storm. We see a lot of caps along the Ship Channel corridor near Channelview and Cloverleaf that have been eaten away by salt air and industrial exhaust. When we replace a cap, we pull the old one, check the flue for hidden damage, install a new cap from Olympia Chimney or Gelco, and seal everything so it holds for years. Cap replacement in Houston generally costs the same as new installation, $325 to $650, unless the flue itself was damaged by exposure and needs additional liner work.

Rust and Salt Air Damage

Homes in Seabrook and Baytown get hit harder by corrosion than inland neighborhoods. A cheap galvanized cap can start rusting through in five years, especially if the cap wasn’t angled correctly during the original install. We replace it with stainless or copper and warrant the work for a full year.

Signs Your Cap is Failing

If you can see daylight through rust holes from the ground, or the cap sits crooked after a windstorm, water is getting in. A replacement is usually a one-hour job. The bigger cost comes later if you ignore it: a waterlogged flue liner cracks faster, and cracked clay liners are a serious fire risk.

Chimney Liner Installation

Chimney Liner Installation means replacing the inner sleeve that channels smoke and combustion gases from the firebox to the outside, and in Houston, it’s the repair we recommend most often after a Level 2 camera inspection. If the clay tile liner is cracked, you’re looking at a fire that can spread into the house framing, because gap-tooth mortar joints expose wood to heat. Flint Chimney Co Houston installs DuraFlex stainless liners sized specifically to your appliance and flue dimensions, and a typical liner installation runs $1,800 to $2,800 depending on flue length and access.

Why DuraFlex Matters

DuraFlex is a continuous stainless steel liner system, which means no clay tile joints, no mortar gaps, and no places for creosote to collect. It’s the brand we spec when the existing liner is cracked or when a homeowner is switching from a furnace vent to a wood-burning setup, and it’s rated for the temperatures that come with regular fireplace use.

When a Liner Can Wait

Not every cracked tile is an emergency. If the firebox is sound and the wood framing is far enough away, we’ll tell you plainly that your liner can wait a year. We show you the camera footage and let you decide. If the crack runs through the full length of the flue or the smoke chamber is heavily glazed with creosote, the liner job is justified and we’ll quote it in writing before you commit to anything.

Chimney Flashing Repair

Chimney Flashing Repair means fixing the sheet metal where your chimney meets the roofline so water stops leaking down around the chimney chase and damaging ceilings, attic insulation, and the roof deck itself. Houston gets about 50 inches of rain per year, and failed flashing is the leading cause of chimney-related water damage we find in homes across Tomball, Jersey Village, and Kingwood. Our repair typically runs $425 to $800 when we can reseal and refasten existing flashing, and $850 to $1,500 when the flashing is too far gone and needs full replacement with new copper or aluminum step flashing.

What Failed Flashing Looks Like

If you have a water stain on the ceiling near the fireplace, or you hear dripping in the attic after heavy rain, the first place we look is the flashing line. Caulk and tar patches fail fast in Houston’s heat. Real flashing repair means cutting back shingles, laying new metal in the proper overlap, and sealing with roofing-grade polyurethane, not silicone squeeze-out.

The Difference Between a Patch and a Fix

A lot of chimney companies will tar the joint and call it a day. Hank Delano has a standing rule: if the metal is still structurally sound, we refuse to layer more caulk over it; if the metal is loose, we replace it correctly or not at all. That’s the Garrison Standard, and it’s why our flashing work lasts, even through hurricane season rain bands.

Chimney Crown Repair

Chimney Crown Repair means rebuilding or resurfacing the concrete slab at the top of the chimney that sheds water away from the flue and brickwork. A cracked crown lets water seep straight down into the brick and the firebox, and Houston’s freeze-thaw cycle, mild as it is, still opens hairline cracks wider every winter. Flint Chimney Co Houston crowns typically cost $550 to $1,000 for crack repair and resurfacing, and $1,200 to $2,200 when the old crown is so deteriorated that we pour a new one with an expansion joint and proper slope.

Why Crowns Crack in Houston

The concrete crown takes a beating from sun exposure and sudden downpours, then it shears when the temperature drops. We also see crowns that were poured too thin by original builders, often under two inches, which is a code violation that was never caught. A proper crown is at least 2.5 to 3 inches thick and overhangs the brick by about an inch and a half, so water runs off instead of running down.

What We Do Differently

We build crowns with a formed overhang and a flexible bond-breaker between the crown and the flue liner, so the two don’t crack against each other as they expand and contract. That detail is the difference between a crown that lasts ten years and one that cracks in two. It’s the same method we’ve used on chimneys in Deer Park, Sugar Land, and every corner of the Houston metro since 2002.

Chimney Repair Companies

Chimney Repair Companies in Houston vary widely in what they actually inspect, and the difference usually shows up in what they write. Some companies quote you over the phone, some send a salesperson with a photo album, and some won’t put anything in writing until you’ve already paid a deposit. Flint Chimney Co Houston operates under the Garrison Code: a written price, a documented scope, and a one-year guarantee before any tool comes off the truck. When you compare Houston repair companies, ask what’s in writing and whether they’ll show you camera evidence of the repair before they do it.

What Separates the Franchise from the Local Shop

A national chain might have the same logos in Houston, Humble, and Sugar Land, but the technician who shows up at your door is the only thing that matters. Our technicians are background-checked and uniformed, and they walk the job site with you before any work starts. The live phone is answered around the clock, and the person who answers can actually schedule your repair.

How to Vet Any Chimney Company

Ask for the warranty in writing. If they hesitate, that’s your answer. Ask whether they’ll show you camera footage before and after. If they won’t, you’re buying assurances instead of evidence. Ask what brands they install. If they can’t name the liner or cap manufacturer, you get whatever is on the truck, and we think you deserve better. We name our materials because they’re verifiable: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, Copperfield.

Chimney Masonry Repair

Chimney Masonry Repair covers brick replacement, mortar joint repointing, and structural rebuilds of the chimney above the roofline. In Houston, brick chimneys take a beating from wind-driven rain and that sticky Gulf humidity that keeps mortar damp for weeks, and we regularly see spalling brick faces on homes in the older neighborhoods around the Heights and Garden Oaks. Our masonry repair starts at $650 for small repointing jobs and runs $1,500 to $3,500 for larger rebuilds where sections of the chimney need to come down and be relaid. Every masonry job gets a written price before we start, and the work carries the full one-year guarantee.

Spalling, Crumbling Mortar, and Loose Brick

When water gets behind the brick face, it freezes and pops the outer layer off, leaving the softer inner brick exposed and eroding. If you can see brick chips on the ground near the chimney, or the mortar joints look like they’ve been carved out, water is moving inside the structure. The fix isn’t caulk. The fix is removing the damaged units, grinding out the old mortar, and relaying with mortar matched to the existing joint profile.

When a Rebuild is the Honest Answer

If more than a third of the brick is spalled or the chimney leans more than a degree off plumb, we’ll tell you the chimney needs a partial rebuild, not a patch. That’s sometimes a hard conversation, but it’s the only honest one. We’ll show you the camera footage from the crown down and the brick-by-brick list of what we’re replacing. No scare tactics, just a clear recommendation and a written line item for every course of brick.

Brands We Service

We work with DuraFlex liners daily. It’s the stainless system we trust for its track record with both wood and gas applications, and we stock the common diameters so a liner job doesn’t stall waiting on freight. Our technicians are trained on DuraFlex’s install specs, which means the liner gets sized, insulated, and supported the way the manufacturer intended.

We also install and repair HeatShield resurfacing systems, which let us save some chimneys from full liner replacement, and we fit caps and chase tops from Olympia Chimney, whose stainless and copper caps we’ve put on hundreds of Houston homes. Whether your chimney uses one of these brands or something else entirely, we can assess it, quote it, and stand behind the work in writing.

Signs You Need a Pro Right Now

• Water stains on the ceiling or wall near the chimney. This almost always means a flashing, crown, or brick water path. Houston rain doesn’t pause for you to get a second opinion, and the longer it runs, the more drywall and framing gets torn out.
• Chunks of brick or mortar on the lawn or roof. Spalling brick doesn’t heal itself. Every loose piece that falls is more surface area for water to work into, and the cycle speeds up from there.
• Strong, foodlike or smoky smell from the fireplace on humid days. Creosote and nesting material absorb moisture and release odor as the humidity climbs. It’s a sign the flue isn’t venting properly and may have structural issues worth a camera look.
• Visible rust holes or a missing cap after a storm. Open flues fill with rain, leaves, and animals. In Houston, after a line of thunderstorms rolls through, it’s worth a glance at the chimney from the yard.
• Smoke rolling back into the room instead of up the flue. A blockage or a cracked liner can change the draft enough that smoke backs up. Carbon monoxide is invisible and odorless, so if the draft is wrong, it’s not a courtesy visit anymore, it’s a safety call.

Our Process, Step by Step

1. 1
   You call and a live person answers. No phone trees. We take the details of what you’re seeing, ask a few questions about the chimney, and set a window for arrival. You get a confirmation and the name of your technician before anyone shows up.
2. 2
   We inspect the chimney with a camera. The technician uses a leveled camera system to look at the flue, the smoke chamber, the crown, the flashing, and the firebox. You see the footage in real time, and we pause it to point out what’s wrong and what’s fine.
3. 3
   You get a written quote. Every recommended repair is written down, line by line, with the exact price, the material brands, and the scope. Nothing is verbal, nothing is “we’ll see when we get in there.” If we can’t know the full extent until we open something up, we tell you that too and split the quote into confirmed and contingent work.
4. 4
   We do the repair and show you the close-out. For liner, crown, and flashing work, we document the finished repair. You get photos or video before we pack up. If something doesn’t look right, you say so, and we stand behind it.
5. 5
   The 365-Day Done Right Promise starts that day. Any covered repair that fails within one full year gets a free return visit and we fix it, no charge. That’s the Garrison Standard, and it’s written on every invoice.
