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
- Gelco GDV series direct-vent gas fireplaces - failed ignition or delayed lighting. The GDV-300 and GDV-400 units common in 2015-2019 McKinney builds use a SIT 820 Nova valve that loses millivolt consistency after 4-6 seasons of North Texas thermal cycling. We test thermopile output at the valve, replace with OEM SIT or a Robertshaw equivalent that meets Gelco’s 750mV minimum, and clock the gas pressure at the manifold before we leave. The fix takes about 90 minutes once diagnosed.
- Gelco wood-burning inserts - cracked refractory panels behind the firebrick. The 26-CI and 32-CI inserts installed during McKinney’s 2016-2020 remodel wave use a three-piece refractory system that hairlines at the corner joints when homeowners over-fire during our brief cold snaps. We pull the baffle, photograph the crack pattern, and replace with Gelco OEM or a HeatShield cerfractory mix if the damage is surface-level. We won’t sell you a full panel set for a crack that stops at 1/8 inch.
- Gelco top-sealing dampers - chain detachment or incomplete seal. The Gelco Lyemance-style damper, popular in Historic Downtown McKinney chimney retrofits, uses a stainless chain that corrodes where it exits the flue cap into our summer humidity. The damper plate then hangs open 3/4 inch, bleeding conditioned air year-round. We replace the chain assembly with a stainless aircraft-cable upgrade from our Famco supplier, reseat the silicone gasket, and test with a smoke pencil at the firebox.
- Gelco gas log sets - sooting or odor complaints in tight McKinney homes. The GL-18 and GL-24 vented sets in newer McKinney construction with spray-foam envelopes often show incomplete combustion from negative pressure. We don’t just clean the logs; we run a combustion analysis, check make-up air paths, and adjust the primary air shutter to Gelco’s 4.0-4.5% CO2 spec. If the house is too tight for vented gas, we tell you before we bill you for a cleaning that won’t solve it.
- Gelco fireplace doors - tempered glass shatter or frame warp. The bi-fold door kits shipped with 2017-2021 Gelco builder boxes use tempered glass rated to 400°F, which fails when homeowners close the doors on a wood fire (a practice the manual prohibits but nobody reads). We measure the opening to 1/16 inch, source replacement glass through our Copperfield account, and install with a new gasket kit. If the frame has warped from the heat event, we fabricate a replacement from steel stock rather than selling you a full door assembly you don’t need.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, asks for your Gelco model number if you have it, and books a 2-hour arrival window. You’ll get a text when your tech is en route.
- 2
Camera-scan inspection. We run our chimney camera per NFPA 211 Level 2 standard, even on gas units, because the flue condition determines what repairs are safe. You watch the footage with us.
- 3
Written diagnosis and price. Corrine Halstead or your assigned tech documents the finding, writes the scope, and gives you the price on paper before any tool comes out of the truck. The camera doesn’t lie, and neither does the written quote.
- 4
Parts decision. We stock common Gelco consumables - igniters, thermopiles, gaskets - and source OEM or quality aftermarket through our Haven buying network. We explain the warranty implication of each choice.
- 5
Repair and test. We complete the work, run the unit through its full cycle, take after photos, and leave you with a written warranty under our 365-Day Done Right Promise.
- 6
Cleanup and documentation. We vacuum, lay down fresh drop cloths for the walkthrough, and upload your photo record to our archive. Haven Standard Clause 4 requires it; we’ve done it since 2009.

Why McKinney Homeowners Call Level Two Chimney McKinney for Gelco Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our McKinney calls involve Gelco products from the 2015-2020 build cycle. Our techs know the difference between a GDV-300 and a GDV-400 valve assembly without looking it up, and our buying relationship with Gelco, DuraFlex, HeatShield, and Olympia Chimney means we don’t mark up parts to compensate for cheap labor.
Every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right. No voicemail trees - a live person answers our line 24 hours a day. And because we’re independently owned and operated under the Haven Standard, the license number on your invoice traces back to a real technician who was background-checked, uniformed, and named before they arrived at your door.
FAQs
No. As an independent Gelco service provider, we use OEM-spec parts and document our work to manufacturer standards. Gelco’s warranty covers defects in materials and workmanship; it does not require factory-authorized service for routine maintenance or repair. We note serial numbers and part sources on every invoice so your warranty record stays clean. Call (469) 429-2623 if you need documentation for a warranty claim.
Common consumables - igniters, thermopiles, gaskets, glass - ship to our McKinney warehouse within 2-3 business days through our Haven buying network. Specialty refractory panels or obsolete damper hardware may take 5-7 days. We stock what fails most often and will tell you before booking if your part is back-ordered. We don’t charge storage or rush fees; the price we write is the price you pay.
Replace when the repair exceeds 60% of a new unit’s installed cost, or when the firebox or flue liner is compromised beyond safe repair. We make that call with camera evidence you can see, not a sales pitch. Many Gelco units from 2015-2019 have plenty of service life left if the refractory and venting are sound. Call (469) 429-2623 for a free inspection and honest assessment.
Annually, per NFPA 211, even if you only run it during our 6-8 weeks of real winter. North Texas dust, spider webs in the vent termination, and valve seal degradation don’t care how often you press the remote. An annual service includes combustion analysis, vent inspection, and safety control testing. Skipping it risks CO spillage or delayed ignition that damages the burner. Call (469) 429-2623 to schedule.
Yes, if the flue liner is sized to the new appliance’s BTU rating and McKinney’s permit office approves the gas line extension. We run a Level 2 camera inspection first, measure the firebox and flue, and give you a written price for the full conversion including permit, liner, gas run, and appliance. We don’t quote conversions over the phone; the flue condition determines whether it’s safe and legal. Call (469) 429-2623 to book the inspection.
