Gelco Chimney Inspection in Dallas: What to Know First
A Gelco chimney inspection in Dallas typically costs between $189 and $449 depending on the level of inspection and what the camera shows us once we’re inside the flue. Most Gelco inspections in the Dallas area take 45 to 90 minutes on site, and you’ll have a written report with photos in hand before we leave the driveway. If you’re reading this, you probably own a home with a Gelco chimney component and want someone who actually knows what they’re looking at, not a technician who’s seeing that nameplate for the first time. That’s exactly who we are.
This page is for homeowners in Dallas with Gelco chimney caps, chase covers, dampers, or flue components who need a straight answer on condition and what it’ll cost to fix what’s wrong. Call (361) 492-4099 and you’ll get a live person, not a queue. We’ll book the inspection at a time we actually show up for.
How Gelco Products Fail – and How We Fix Them
Gelco builds solid chimney components, but like any product exposed to Texas heat, Dallas thunderstorms, and creosote, they have predictable failure points. Here’s what we see on Gelco inspections across Dallas, and what we do about it.
- Gelco chase covers rusting at the seam. The standard Gelco chase cover on older Dallas homes is galvanized steel with a folded seam, and that seam is where water gets in first. After a few Dallas seasons of hail and humidity, the seam starts to separate. We can often reseal and extend the life of the cover; when the metal is too far gone, we spec a replacement and put it in writing before any work starts.
- Gelco multi-flue caps losing their screen. We inspect a lot of Gelco multi-flue caps in the M Streets and Lake Highlands neighborhoods where masonry chimneys run side by side. The screen mesh on the underside catches embers and creosote flakes, and once it corrodes, birds and squirrels get in. We’ll tell you honestly whether the cap can be repaired or should be replaced, and what each option costs.
- Gelco dampers sticking shut or swinging open. A Gelco damper that won’t close is a draft problem; one that won’t open is a smoke problem. The pivot hardware on these dampers collects soot and surface rust, and the cable or lever mechanism binds. We clean the assembly, lubricate the pivot points with a high-temp lubricant, and test the full range of motion before we call it done.
- Gelco flue tiles with spalling faces. When a Dallas home with a Gelco flue liner burns a winter’s worth of fires, the clay tiles absorb moisture, then the heat cycling makes the faces flake off. Spalled tile faces are a fire-safety issue, not a cosmetic one. We’ll show you the camera footage, mark the exact location of the damage, and give you a repair price on the spot if it’s needed.
- Gelco top-mount dampers losing their seal. The silicone gasket around a Gelco top-mount damper hardens under direct Texas sun and stops sealing. You’ll feel the draft on a windy Dallas night. We replace the gasket rather than the whole unit when the frame is still sound, and we’ll tell you if the frame has warped beyond saving.

Our Gelco Chimney Inspection Process
Every Gelco inspection we run in Dallas follows the same sequence. No shortcuts, no guessing, no surprise charges. Here’s how a typical job goes from your first call to our final walkthrough.
- 1
You call, we book. A live person answers at (361) 492-4099, takes your address and what you’re seeing, and gives you a firm arrival window. We run on the window, not on “sometime Thursday.”
- 2
We walk the fireplace with you. Before any tool comes off the truck, we look at the Gelco components from the firebox, listen to what you’ve noticed, and tell you what we’re going to inspect and why. This takes about ten minutes and costs nothing extra.
- 3
We run the camera through the flue. This is the part that separates a real inspection from a quick look. The camera shows us exactly what’s happening inside the Gelco flue liner, the damper seat, the smoke shelf, and the cap. You’ll see the screen right alongside us. If the flue’s clear, I’ll tell you. If it’s not, I’ll show you exactly why.
- 4
We document everything. Photos of every finding, marked on the report so you can find the same spot again. No verbal hand-waving. If we say the chase cover seam is failing, you’ll have a photo of that seam in your report.
- 5
We price it in writing. If repairs are needed, you get a written quote before any work begins. That quote is the number you’ll pay. No “while we’re in there” surprises, no scope creep. We also tell you plainly what can wait and what can’t.
- 6
We finish and clean up. Inspection debris stays out of your living room. We leave the hearth the way we found it, walk you through the report one more time, and make sure you understand your warranty if a repair is part of the job. Every repair we make carries a written guarantee valid for one full year from the service date.

AfterWhat Gelco Chimney Inspection Costs in Dallas
Here are honest numbers, because you shouldn’t have to call just to get a ballpark. A Level 1 inspection on a Gelco chimney in Dallas runs $189 to $249 for a fireplace you’ve been using without problems. A Level 2 inspection, which includes the full camera run and is standard for real estate transactions or after a chimney fire, runs $329 to $449. A Level 3 inspection, where we open a portion of the chimney to access hidden components, starts at $799 and up depending on access.
What moves the price: roofline height, the number of flues, whether the Gelco components show signs of water intrusion, and how much creosote needs to be cleared before the camera can even see the liner. We give you the written price before we start, every time. Call (361) 492-4099 for a free estimate on your specific Gelco setup.
Why Dallas Homeowners Call Flint Chimney Co Dallas for Gelco Work
We’ve been part of the Garrison Partners family since 2002, and we operate under the Garrison Standard: written pricing, written guarantees, and technicians who arrive on time and own their work. Every Gelco inspection we run in Dallas gets the same treatment as a repair we’re installing.
Our techs know Gelco components by sight, and when a Gelco part needs replacement, we’ll be straight with you about OEM versus quality aftermarket options. Sometimes the OEM part is the right call. Sometimes a DuraFlex liner or a HeatShield repair is the smarter long-term fix than patching a failing Gelco flue tile again. We’ll put both options in writing and let you decide with the facts in front of you. And every repair we make, Gelco or otherwise, carries our 365-Day Done Right Promise: if a covered repair fails within a year, we come back and fix it at no charge. That’s not a marketing line. It’s the same code every Garrison Partners location follows.
We’re an independent Gelco service provider, not a Gelco-authorized shop. What that means for you: we have no factory quota to hit and no reason to recommend a part you don’t need. We’ll tell you what your Gelco chimney actually needs, and we’ll stand behind it in writing.
FAQs
No. A visual or camera inspection performed by a qualified chimney service does not void a Gelco warranty. In fact, skipping inspections is what voids coverage, because most manufacturer warranties require routine maintenance and will deny claims for damage that reasonable maintenance would have caught. We document everything in the report so you have a paper trail if you ever need to file a Gelco warranty claim.
Most Dallas homeowners get an inspection within 3 to 5 business days of calling. We do not run same-day emergency slots, but we do answer the phone live 24/7, so you’ll at least get a real person and a real arrival window the first time you call. If you’re under contract on a house and need a Level 2 inspection before closing, let us know the deadline and we’ll work with your schedule.
When a Gelco component is still within its service life, we prefer OEM parts for direct replacements, especially dampers and caps where fit is critical. But we won’t push an OEM part when a quality aftermarket equivalent does the same job for less. We’ll show you the price difference on both options and you decide. Any part we install is covered under our one-year written guarantee regardless of who made it.
Yes, and we’ll show you the camera footage so you’re not taking our word for it. The two things we’re looking for: creosote buildup thick enough to be a fire hazard, and structural damage to the liner itself like cracks, gaps, or spalling. If it just needs a cleaning, we’ll tell you that and price it separately. If it needs relining, we’ll show you exactly where and why on the screen, then give you a written quote. Nothing gets recommended without evidence you can see yourself.
Every repair we make is backed by a written guarantee valid for one full year from the service date. If a covered repair fails during that year, we return at no charge and make it right. You don’t have to argue with a dispatcher or prove your case. You call, we come back, we fix it. That’s the Garrison Standard, and it applies to every Gelco repair we do in Dallas. Call (361) 492-4099 to schedule your inspection, and you’ll have the written price before we touch anything.
