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.

How Gelco Products Fail - and How We Fix Them
We’ve worked on enough Gelco units across Plano to know where they tend to break. Here are the failure patterns we see most often:
- Gelco gas inserts with intermittent pilot ignition failures. The SIT 820-series valve and pilot assembly on older Gelco direct-vent inserts collects ceramic dust and spider silk during North Texas spring swarms. The pilot lights, then drops out after thirty seconds. We pull the assembly, clean the orifice with a numbered drill bit (never a wire brush, which oval the bore), and test flame rectification signal in millivolts before we leave. If the valve body is cracked from overtightening during a previous service, we source OEM or a White-Rodgers equivalent through our Haven buying network.
- Gelco wood-burning fireboxes with cracked refractory panels. The 36F and 42F models shipped with medium-duty refractory that spalls after repeated thermal cycling, especially when homeowners in Plano run all-night burns during our brief but sharp cold snaps. We measure the crack width and location per NFPA 211; hairline cracks away from the grate rails get documented, but through-cracks or panel separation get replacement with HeatShield refractory replacement panels or OEM Gelco kits, depending on availability and your preference.
- Gelco pre-fab chimney systems with rusted chase covers. The stamped-steel chase covers on Gelco’s 1980s and 1990s factory-built wood fireplaces pool water at the corners, then rust through and dump water onto the firebox top. In Plano’s clay-heavy soils, that moisture wicks into the framing. We fabricate a replacement chase cover in galvanized or stainless steel with a proper cross-break and drip edge, or source a Gelco-compatible unit from Famco if the dimensions are standard.
- Gelco dampers that won’t open fully or seal shut. The cast-iron throat dampers on Gelco’s traditional masonry-style wood fireplaces seize from creosote glazing or handle linkage fatigue. We camera the flue first to rule out a fallen liner or obstruction, then free the damper, dress the pivot pins, and replace the handle assembly if the spline is stripped. For units where the damper frame itself is warped from overfire, we document the gap with the camera and quote a lock-top damper or firebox rebuild.
- Gelco direct-vent terminations with discolored or melted louvers. The horizontal termination caps on certain Gelco B-vent and direct-vent gas units sit too close to vinyl siding on tighter Plano lot setbacks, or the interior baffle fails and lets exhaust wash the outer wall. We check clearances to combustibles with a laser measure, verify the venting run against the installation manual, and replace with an OEM Gelco termination or a code-compliant aftermarket equivalent from DuraFlex if the original is obsolete.
Our Gelco Fireplace Services Process

- 1
Book the inspection. You call (469) 240-3101 and speak to a live person. We schedule a Level 2 camera inspection, not a flashlight sweep. Corrine Halstead or a named, background-checked technician is assigned, and you get a text when we’re en route.
- 2
Inspect and document. We run a chimney camera down the flue, photograph the firebox, damper, and gas components, and record any readings (gas pressure, draft, CO). You see what we see. Clause 4 of the Haven Standard requires this photo record on every job.
- 3
Diagnose and price in writing. We name the failure, explain why it happened, and hand you a written scope with a flat price and a written warranty before any work begins. Haven Standard Clause 1: have it in writing.
- 4
Source parts correctly. For Gelco units, we check OEM availability against quality aftermarket options from our Haven buying network, DuraFlex, HeatShield, or Copperfield. We tell you which we’re using and why.
- 5
Repair, test, and document again. We complete the work, run the unit through a full burn cycle or gas leak check, and add completion photos to your record.
- 6
Guarantee and follow up. The 365-Day Done Right Promise covers labor and materials. If it’s not right, we make it right. Your documented record lives in our archive, every job since 2009.

Why Plano Homeowners Call Emberly Chimney Cleaners Plano for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those have been Gelco units in Plano and Collin County. The camera doesn’t guess. Neither do we. Our technicians are background-checked, uniformed, and carry license information you can verify. We source materials through our Haven buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield specifically to keep customer prices honest. As an independent Gelco service provider, we’re not bound to factory-only parts or factory-only pricing. If your Gelco unit needs a repair, a conversion, or an honest assessment of whether it’s worth fixing, we hand you the photos, the written price, and the time to decide.
FAQs
No, professional service by a qualified technician does not void your Gelco warranty, though using non-OEM parts for certain components may affect specific parts coverage. We note OEM versus aftermarket on every written quote so you can decide before we start. Call (469) 240-3101 if you’d like us to review your warranty terms against the proposed repair.
Every year, per NFPA 211, regardless of apparent use. Plano’s mild winters mean many homeowners burn sporadically but intensely during cold snaps, which produces more creosote per hour than steady low burns. We find Class III glazed creosote in Gelco wood units that “only get used a few times a year” more often than you’d expect. Call (469) 240-3101 to schedule - estimates are free.
Many Gelco parts are available through our Haven buying network or aftermarket suppliers like DuraFlex and HeatShield; some OEM components for pre-2000 units are obsolete. We check availability during inspection and present options, including compatible replacements, before any work begins. Call (469) 240-3101 and we’ll run the part number.
We camera the system, show you the footage, and explain the fix versus replacement math in plain terms. A cracked firebox in a 15-year-old prefab often warrants replacement; a failed gas valve in a 5-year-old insert usually doesn’t. We write both prices when it’s close, and we tell you plainly when work can safely wait. Call (469) 240-3101 for a free estimate.
Most Gelco jobs are scheduled within a week, and we keep common parts in stock for faster turnaround on typical repairs. Emergency gas leaks or CO concerns get prioritized. Call (469) 240-3101 for availability - estimates are free.
