Gelco Chimney Cap & Crown in Houston, TX

Gelco Chimney Cap & Crown in Houston: What to Know First

We provide independent Gelco chimney cap and crown service across Houston, from the Heights to Sugar Land, with most calls scheduled within 48 hours and completed in a single visit. A standard Gelco cap replacement runs $280-$520; crown repair or coating typically falls between $340-$780, depending on access and how far the damage has spread. We do not quote over the phone for crown work without seeing it, because a crown that looks cracked from the ground can be structurally sound, and one that looks fine can be hollow underneath.

Call (877) 516-5603

This page is for homeowners who already know they have a Gelco cap or crown and need someone who understands how these products age in Houston’s particular climate - the Gulf humidity, the hard sun on south-facing flues, the surprise freezes that catch masonry crowns off guard. If that describes your situation, call (877) 516-5603. A live person answers, even at 11 p.m. on a Sunday.

How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue caps with the original mesh design (pre-2018 series): The 5/8-inch mesh that Gelco used on earlier multi-flue caps corrodes faster than their current 304 stainless weave, especially within three miles of the Ship Channel where salt air settles. We see this in Pasadena, Seabrook, and anywhere the morning fog carries that metallic tang. Our fix is a full cap replacement with current-spec Gelco mesh or, if the frame is still sound, a custom mesh swap that preserves the original mounting footprint.
• Gelco single-flue caps with the stamped galvanized base: The galvanized steel base on certain economy-series single-flue caps will outlast the factory fasteners by a decade, but the fasteners themselves seize and shear when you try to remove the cap for sweeping access. We’ve learned to drill these out rather than fight them, then upgrade to stainless hardware on reinstallation. It’s a small thing, but it saves the homeowner a second service call.
• Gelco crown-forming caps on older Houston homes: These integrated cap-and-crown units, common on 1980s and 1990s construction in Bellaire and West University, trap water at the crown interface because the drip edge was undersized for our rainfall volume. The crown beneath erodes while the cap looks fine from the street. We remove the cap, rebuild the crown with proper slope and overhang, then reinstall or replace the cap with corrected drainage geometry.
• Gelco wind-directional caps in open Gulf exposure: The wind-directional series works well inland, but on homes in League City or Clear Lake with unobstructed south exposure, the constant pivot wear loosens the bushing until the cap seizes in one position or rattles loose entirely. We inspect the bushing and pivot pin during every Level-2 camera inspection; replacement with the current Gelco heavy-duty pivot kit, or a switch to a fixed high-wind cap, solves it permanently.
• Gelco chase covers on prefab chimneys: The factory Gelco chase cover on many prefab installations uses a flat-top design with recessed corners that pond water during our spring deluges. By year twelve, that standing water has rusted through at the corners or caused the underlying wood chase to rot. We replace with a Gelco cross-break chase cover or, if the chase is too far gone, rebuild the chase top with proper slope and a Gelco cap integrated into the new construction.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your Gelco model if you know it, and books a Level-2 camera inspection. Most appointments are within 48 hours; same-day is often possible in the Houston metro.
2. 2
   Inspection and documentation. Our technician arrives in uniform, photographs the cap or crown from multiple angles, and runs the camera if crown damage is suspected. You see the photos and get a plain-English verdict before any work is proposed.
3. 3
   Parts decision. If your cap is a current Gelco series, we quote OEM replacement. For discontinued lines, we source quality aftermarket equivalents that match the mounting pattern and flue dimension, or fabricate from Gelco-compatible components. We explain the trade-off and let you decide.
4. 4
   The repair. Crown work gets proper surface prep, bonding agent where needed, and slope correction so water runs off. Cap installations get stainless fasteners, proper clearances, and a smoke test to confirm draft. Most jobs finish in one visit.
5. 5
   Cleanup and guarantee. We haul away the old material, leave the roof and hearth as we found them, and document the completed work with photos. The 90-Day Done Right Promise applies in writing: if it’s not right, we come back, no paperwork, no arguing.

Why Houston Homeowners Call Hearthstone Chimney Co. of Houston for Gelco Work

We’ve been answering the phone with a live person for over 42 years, and we plan to be here when your next chimney needs attention. Dale Hutchins, our owner and master sweep, grew up in the Heights watching those old bungalows on Oxford Street go from “nobody pays attention to the fireplace” to “something’s leaking through the ceiling.” He built Hearthstone on the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.

Our technicians are background-checked, uniformed, and trained on Gelco’s product evolution - they know which series used galvanized vs. stainless, which fasteners seize, which caps work on the Gulf Coast and which don’t. We back every job with the 90-Day Done Right Promise in writing. And if your situation calls for materials beyond Gelco, we carry DuraFlex, HeatShield, and the other professional-grade brands we trust. A clean flue doesn’t announce itself. That’s the point.
