Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning & Sweep in Dallas: What to Know First
We provide independent Gelco chimney cleaning and sweep in Dallas with a written price before any work starts and a camera-scan inspection included on every visit. Most Gelco jobs in the Dallas metro book within a few days and finish in two to four hours, depending on creosote buildup and whether the flue liner needs attention. We’re not affiliated with Gelco; we service their products as an independent Gelco service provider using the same materials we source through our Haven buying network.
This page is for Dallas homeowners running a Gelco chimney cap, Gelco top-sealing damper, or Gelco liner system who need annual sweeping, creosote removal, or a Level 2 inspection before burning season. If you’re in Lakewood, Lake Highlands, or the older neighborhoods off Mockingbird where Gelco caps from the 2010s are starting to show age, you’re who we wrote this for. Call (972) 284-1392 for a free estimate with a written price delivered before we start.
How Gelco Products Fail - and How We Fix Them
- Gelco Model E top-sealing dampers - The silicone rubber gasket hardens faster in Dallas than in northern markets because UV exposure through the chimney throat combines with our temperature swings. We see this in Preston Hollow and Richardson homes where the damper was installed 8-12 years ago. The fix is a gasket replacement with OEM Gelco spec or a Haven-approved aftermarket equivalent; we test the seal with a smoke pencil and photo the result.
- Gelco single-flue chimney caps in the Multi-Flue series - The 18- and 24-inch models collect creosote at the mesh corners where Dallas oak and pecan smoke condenses. The mesh can clog completely if annual sweeping skips a year, and the stainless can pit underneath. We pull the cap, ultrasonic-clean the mesh when possible, or source a replacement through our Olympia Chimney supply line if the pitting has breached the metal.
- Gelco liner top plates with integrated spark arrestors - The arrestor screen welds fatigue from thermal cycling; Dallas burns short and hot rather than long and low, which is harder on welds. We document the crack with the camera from below, then replace with a Gelco-compatible top plate or a DuraFlex equivalent if the homeowner wants a different price point.
- Gelco Pre-Fab chimney systems (factory-built metal chimneys) - The joint collars loosen where the chimney passes through the attic space, especially in homes built during the 2015-2020 Dallas construction boom where chase framing settled. Our Level 2 inspection catches this with the camera; we reseat the collar and seal with HeatShield Cerfractory Foam where the factory seal has failed.
- Gelco Lyemance and Lock-Top damper chains - The stainless cable frays at the handle pivot after repeated use. In Dallas, we see this more often on second fireplaces that get opened and closed seasonally rather than left in one position. We replace the cable assembly, lubricate the throat, and test the damper plate seating under load.
Our Gelco Chimney Cleaning & Sweep Process

- 1
Call and schedule. A live person answers, checks availability in Dallas or your suburb, and notes your Gelco model if you know it. We don’t quote over the phone; we quote in writing after inspection.
- 2
NFPA 211 Level 2 inspection with camera. Our tech runs the camera down the flue, photographs the Gelco liner, damper, and cap from the inside, and records creosote class and thickness. Camera goes in first. Everything else follows.
- 3
Written price and scope. You get a printed price, a written description of work, and the warranty terms before anyone picks up a tool. Clause 1 of the Haven Standard: have it in writing.
- 4
Sweep and service. We remove creosote with rotary whips or hand brushes matched to your Gelco flue diameter, clean the smoke chamber, and service or replace any failed Gelco component with OEM or Haven-approved parts.
- 5
Post-work documentation. After photos, draft readings where applicable, and a signed completion record. Clause 4 of the Haven Standard requires this archive; we’ve done it since 2009.
- 6
365-Day Done Right Promise activation. If anything we touched needs correction within a year, we make it right. The promise is stamped on your paperwork.

AfterWhat Gelco Chimney Cleaning & Sweep Costs in Dallas
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Annual Gelco chimney sweep (Level 1) | $189 - $269 | Roof access difficulty, creosote class (I vs. III), cap removal required |
| Level 2 inspection with camera | $289 - $389 | Number of flues, attic or chase access, documentation copies needed |
| Gelco damper gasket replacement | $340 - $520 | OEM vs. aftermarket gasket, throat condition, handle assembly wear |
| Gelco cap mesh cleaning or replacement | $180 - $450 | Ultrasonic clean possible vs. full replacement, stainless gauge |
| Creosote removal (Class III glazed) | $420 - $680 | Flue length, chemical pretreatment cycles needed, liner material compatibility |
These are Dallas-market prices for Gelco-specific work, not national averages. A two-flue system in a Lake Highlands ranch with easy roof access sits at the lower end; a three-story Mockingbird Lane home with a steep pitch and glazed creosote sits higher. We don’t start work until you approve the written price. Call (972) 284-1392 for a free estimate - estimates are free, and the price we give is the price you pay.
Why Dallas Homeowners Call Level Two Chimney Dallas for Gelco Work

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those were Gelco caps, dampers, and liners in Dallas homes. Corrine Halstead learned the trade at Apex Technical School in Long Island City before relocating to Texas, and she’s built a crew that knows Gelco hardware by sight - not from a catalog, from repeated jobs in the same neighborhoods.
Our technicians are background-checked and uniformed; you get a text when yours is en route with a name and photo. We also carry DuraFlex and HeatShield materials, so if your Gelco component has failed in a way that an alternative solves better or cheaper, we’ll show you both options on camera and price them both in writing. The 365-Day Done Right Promise applies either way. Live phone support runs 24 hours a day, 7 days a week.
FAQs
No - Gelco’s product warranties cover manufacturing defects, not who services them. As an independent Gelco service provider, we use OEM-spec or Haven-approved parts and document our work, which supports any warranty claim you need to file with Gelco directly. Keep your Clause 4 photo record and written scope; they’re your evidence. Call (972) 284-1392 if you need help interpreting warranty language.
We determine this with the camera and a smoke-pencil test, not guesswork. If the damper plate seats clean and the gasket passes the smoke test, we clean and lubricate. If the throat is warped, the cable frayed, or the gasket hardened past sealing, we quote replacement in writing. You’ll see what we saw before deciding. Call (972) 284-1392 for an exact quote - estimates are free.
Most common Gelco caps, dampers, and gaskets are in our supply chain within 24-48 hours through our Haven buying network, which includes Olympia Chimney and Famco distribution. Rare or discontinued Gelco models may take longer; we’ll tell you exactly which part and which timeline before you commit. Call (972) 284-1392 for availability on your specific model.
NFPA 211 recommends annual inspection; sweeping frequency depends on use and fuel. In Dallas, where homeowners tend to burn concentrated evening fires on cool nights rather than all-day heating, we often find light Class I creosote at one year and heavier buildup at two. Annual sweeping is the safer baseline, especially with Gelco pre-fab systems where creosote accumulates at joint collars. Call (972) 284-1392 to schedule - estimates are free.
Class I creosote becomes Class III glazed creosote, which restricts draft, accelerates liner corrosion, and increases chimney fire risk. In Dallas, our dry winters and sudden cold snaps mean fires get built hot and fast - the exact conditions that ignite glazed deposits. A skipped year turns a $189 sweep into a $600+ removal job, and if the liner is damaged, replacement follows. We document everything so you know what’s urgent and what can wait. Call (972) 284-1392 for a free estimate.
