Our Chimney Cap & Crown Services in Highlands
Crown Coating
Crown coating is our most requested chimney service in Highlands, and for specific reasons. The concrete crown at the top of your chimney takes the worst abuse - Gulf Coast humidity, driving rain from tropical systems, and airborne sulfur compounds from the Ship Channel corridor that settle into porous concrete and eat it from within. We apply a professional-grade flexible crown coating, typically HeatShield or Gelco, that seals hairline cracks and prevents water from reaching the mortar joints beneath. A typical crown coating in Highlands runs $280-$450. Most applications take two hours and cure overnight. We document the before condition with photos you can see, and we don’t leave until the crown sheds water properly.
Custom Cap Fabrication & Installation
Standard galvanized caps from big-box stores fail fast here. We’ve measured it - galvanized steel caps in Highlands pit and perforate within 5 years from airborne sulfur compounds and hydrogen sulfide drifting off the petrochemical corridor. That’s why we fabricate and install custom caps using heavier-gauge materials, including copper options from Copperfield that develop a protective patina instead of rusting through. We recently swapped a rusted-through steel chimney cap on a 1950s brick home near Kaminski Park. The old cap had been eaten alive by industrial-soot-laden condensation, despite the homeowner never lighting a fire. We installed a custom copper cap from Copperfield with a Gelco crown coating to seal the corroded crown. Custom cap installation in Highlands typically runs $340-$620 depending on flue count and material.
Multi-Flue Cap Replacement
Many Highlands homes, especially the larger 1960s and 1970s brick ranches near Decker Drive, were built with multiple fireplaces sharing a single chimney structure. Multi-flue caps corrode at welded joints from acidic soot buildup, even on idle chimneys, leading to cap collapse and flue exposure to wildlife. We measure each flue precisely and order or fabricate caps with proper clearance and screening. Multi-flue cap replacement in Highlands runs $420-$780. We use stainless or copper construction - no galvanized steel that won’t survive the local air.
Cap Replacement (Standard Single-Flue)
Sometimes the crown is sound and only the cap has failed. We carry common sizes for immediate replacement, and we can measure and order custom fits for odd-size clay flue tiles common in Highlands’s post-war construction. Single-flue cap replacement runs $180-$340 installed. We check the flue liner condition while we’re up there - no extra charge for the look.

Trusted Brands We Service in Highlands
We stock and install professional-grade materials from Olympia Chimney, Gelco, and HeatShield - brands that hold up to the specific corrosion challenges of the Ship Channel airshed. We don’t use builder-grade substitutes. Our trucks carry common cap sizes and crown coating supplies, so Highlands customers aren’t waiting on parts while rainwater seeps into their firebox. When we need to fabricate a custom copper cap, we source through Copperfield with typical turnaround of 48-72 hours. The materials cost more than box-store alternatives. They also last.
Common Chimney Cap & Crown Problems We See in Highlands Homes
- Galvanized steel caps pit and perforate within 5 years due to airborne sulfur compounds from nearby refineries along Crosby Freeway. We’ve replaced caps that looked fine from the ground but were paper-thin at the crown when we got up close.
- Clay tile liners crack from freeze-thaw after water seeps past a deteriorated crown, worsened by heavy rainfall events like Hurricane Harvey. The 77562 area saw significant flooding in 2017, and we’re still finding water-damaged fireboxes and warped dampers in homes that took even minor intrusion.
- Multi-flue caps corrode at welded joints from acidic soot buildup, even on idle chimneys, leading to cap collapse and flue exposure to wildlife. Chimney swifts are protected; once they nest, you can’t legally remove them until they migrate.
- Industrial soot deposits coat fireboxes and smoke shelves regardless of fireplace use - a dark, oily residue distinct to the Ship Channel airshed that signals liner corrosion risk even in homes where the fireplace hasn’t been lit in a decade.

FAQs - Chimney Cap & Crown in Highlands
Airborne sulfur compounds and hydrogen sulfide from the Houston Ship Channel petrochemical corridor create acidic condensation inside idle chimneys that corrodes metal caps far faster than wood smoke alone. This chemical deterioration pattern is almost never seen in suburban Houston markets west or north of the Ship Channel. We replace rusted caps with stainless or copper materials that resist this specific corrosion. Call (877) 516-5603 for a free inspection - we’ll show you photos of what we find.
Look for cracks in the concrete crown visible from the ground, rust streaks on the brick below the cap, or water stains on the ceiling near the fireplace. In Highlands’s 50-70-year-old chimneys, we commonly find crowns that have deteriorated to the point of funneling water directly into the flue structure. Our Level-2 camera inspection ends with photos you can see and a plain-English verdict. Schedule yours at (877) 516-5603.
That residue is industrial soot specific to the Ship Channel airshed - a mixture of airborne particulates and sulfur compounds that settle in idle flues and combine with humidity to form a corrosive film. It signals that your liner and cap are being chemically attacked regardless of fireplace use. We see this regularly in Highlands homes near the Crosby Freeway corridor. A cap replacement and crown sealing can stop the intrusion. Call (877) 516-5603 for an exact quote - estimates are free.
Yes - a properly fitted cap with intact screening blocks chimney swifts, which are federally protected and cannot be removed once they nest. In Highlands, where chimneys sit idle in moisture-laden air for most of the year, swifts find inviting entry through corroded or missing caps. We install caps with proper mesh sizing that keeps birds out while allowing exhaust flow. Call (877) 516-5603 before spring nesting season begins.
Floodwater that reaches the firebox base can warp damper assemblies, accelerate rust on metal components, and introduce silt that holds moisture against liner walls long after the water recedes. In Highlands, where many homes took water in 2017, we’ve found crown cracks that went unnoticed until freeze-thaw cycles expanded them into serious leaks. If your home flooded, we recommend a Level-2 inspection to document cap, crown, and liner condition. Call (877) 516-5603 - we’ll be there when we say.
