Gelco Chimney Repair in Fort Worth: What to Know First
Gelco chimney repair in Fort Worth typically runs $450 to $2,800 depending on whether you need mortar repointing, flashing work, or a partial rebuild. Most Gelco repair jobs we book are completed in one visit, and every one starts with a written price before any tools come off the truck. If you own a home with a Gelco chimney system and something looks or smells wrong, call (682) 255-2144 and we’ll tell you straight what it will take to fix it.
This page is for Fort Worth homeowners who have a Gelco chimney system or Gelco components and need an independent repair crew that actually knows the product. We are not authorized by Gelco, and we don’t pretend to be. We’re an independent Gelco service provider that has pulled apart enough of these systems over the years to know exactly where they fail and what it takes to put them right.
How Gelco Products Fail – and How We Fix Them
Gelco makes a range of masonry and chimney products, and in Fort Worth we see specific failure patterns tied to our clay soil, hard water, and the freeze-thaw cycles that hit older brickwork hard. Here is what we find, in plain terms:
- Gelco weatherproofing membranes worn thin on the crown. The factory-applied coating on some Gelco chimney caps and crowns degrades faster in North Texas sun than it does in milder climates. The crown starts absorbing water, the water works into the mortar bed, and the cycle begins. We strip the old membrane, repair the crown substrate, and recoat with a professional-grade waterproofing compound specified for the job.
- Mortar joint erosion around the Gelco flue tile joints. Gelco flue tiles hold up, but the mortar holding the tile stack together takes a beating from acidic flue gases and Fort Worth humidity swings. Homeowners notice white staining or loose grit at the cleanout. We cut out the failing joints and repoint with a high-temperature mortar rated for flue service, not whatever the box store sells.
- Flashing failure at the roofline where Gelco systems meet the roof deck. This is the single most common Gelco-related repair we do in Fort Worth. The metal flashing that seals the chimney to the roof corrodes or lifts, and water gets behind it. The fix is a new step flashing and counterflashing setup sealed with a modern polyurethane sealant, not roofing tar. Hank Delano insists on this: tar is a patch, not a repair.
- Spalling brick on the exterior fascia. Spalling is brick face popping off, and on Gelco-faced chimneys the brick often starts failing at the water table, three or four courses above the roof line. The cause is usually a failed crown letting water into the brick from above. We address the crown first, then cut out the spalled brick and replace it with a matched brick and mortar that breathes correctly.
- Cracked Gelco chimney caps allowing direct water intrusion. A hairline crack in a cast cap can let water straight down the flue. You will not see it from the ground. We spot it during an inspection, and the repair is usually a full cap replacement or a concrete patch if the crack is small and stable. Either way, the price is on paper before we lift a trowel.

Our Gelco Chimney Repair Process
Every Gelco repair job follows the same sequence. No shortcuts, no surprises, and the price is set before work begins. Here is how it runs:
- 1
Call and book. A live person answers the phone at (682) 255-2144, day or night. We schedule a time that fits your week, not ours.
- 2
On-site inspection. The technician walks the roof, checks the crown, flashing, mortar, and the flue interior if access allows. You get a level inspection: exactly what we see, nothing softened.
- 3
Written price. Before any work starts, you get a written quote showing the scope, the materials, and the total. If you approve that number, that is the number on the invoice. If you do not, we leave the site clean and you owe us nothing.
- 4
The repair. We decide on OEM Gelco parts or a quality aftermarket match based on what the job actually needs and what will hold up in Fort Worth weather. For structural work we use professional-grade materials from the brands we trust: Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. We specify by job, not by margin.
- 5
Test and verify. Water intrusion work gets a hose test. Mortar and brick work gets a cure inspection before we pack up. If it is not clean and it is not safe, we are not done.
- 6
Written guarantee. Every repair carries the 365-Day Done Right Promise. If a covered repair fails within one full year, we return at no charge. The guarantee is on the invoice, in writing, where you can find it.
What Gelco Chimney Repair Costs in Fort Worth
Here are the honest ranges we quote in Fort Worth for common Gelco repairs:
- Mortar repointing (tuckpointing): $450 to $1,100 depending on how many courses are failing and how much grinding the old joints require.
- Flashing repair or replacement: $500 to $1,600 depending on roof pitch, accessibility, and whether we are replacing one run or the full perimeter.
- Chimney waterproofing: $350 to $700 for a standard single-flue chimney, including surface prep and two coats.
- Crown repair or recoat: $400 to $900, including removal of the old material and fixing the substrate.
- Partial chimney rebuild: $1,800 to $3,500 for the top 10 to 15 courses, depending on brick matching difficulty and access.
- Spalling brick replacement: $40 to $90 per brick, with most jobs running 10 to 30 bricks.
The price moves based on two things: access and the condition of what is underneath. A chimney on a two-story house with a steep roof costs more in labor than a one-story bungalow. A crown that has been leaking for ten years costs more than one caught early. We give you the number in writing before work starts, and the estimate is free. Call (682) 255-2144.

Flint Chimney Co Fort Worth has been part of the Garrison Partners family since day one, founded in 2002 and built on The Garrison Standard: a written price before the work, a written guarantee after it, and a uniformed, background-checked technician on every job.
When it comes to Gelco repairs, the advantage is that we work with the full stack of chimney trade materials. If a Gelco part makes the most sense, we use Gelco. If a DuraFlex liner or a HeatShield resurfacing treatment is the better fix for your flue, we will tell you that instead, and we will put the recommendation in writing. You get a crew that runs on discipline, arrives inside the window given, and stands behind the work for a full year. The 365-Day Done Right Promise is exactly what it sounds like: if a covered repair fails within 365 days, we return and make it right at no charge.
FAQs
In most cases, no. As an independent Gelco service provider, we use either OEM Gelco parts or quality aftermarket equivalents matched to the system, and we do not modify factory components beyond the scope of the repair. If you have an active Gelco warranty, we recommend you confirm coverage directly with Gelco, and we will always document our work so you have a clear record of what was done and why.
Sometimes. Gelco has changed product lines over the years, and certain older components are no longer in production. When an OEM Gelco part is available, we use it. When it is not, we specify a proven aftermarket equivalent from brands like Olympia Chimney or Copperfield that matches the original spec. The written quote will always say which one we are using and why.
Most Gelco repairs are booked within a week, and many mortar, flashing, and waterproofing jobs are finished the same day we start. A partial rebuild takes longer, usually two to three days including cure time. Call (682) 255-2144 and we will give you a realistic window when you book, not an optimistic one.
Repair is the right call when the damage is limited to mortar joints, flashing, the crown, or isolated brick. Rebuild makes sense when the masonry has moved, water has compromised the structure below the roof line, or repair costs would approach the cost of starting fresh. We will tell you which side of that line you are on, and we will show you photos from the inspection so you can see it for yourself.
You call us, we come back, and the repair is done again at no charge. The 365-Day Done Right Promise covers our workmanship for one full year from the service date. It is on every invoice, in writing.
