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 Fireplace Services in Arlington Heights: What to Know First
We provide independent Gelco fireplace services in Arlington Heights, from gas valve troubleshooting on the GVF series to firebox reline work on older wood-burning units. Most Gelco jobs run same-week, and every one starts with a written price before we touch a tool. If you’re seeing delayed ignition on a Gelco insert, a stuck damper on a factory-built unit, or you’re not sure whether your firebox cracks need refractory panels or a full reline, we can sort it out. Call (331) 202-2419 to book. We serve homes throughout Arlington Heights, including the older colonials near Campbell Street and the newer builds off Rand Road.

How Gelco Products Fail - and How We Fix Them
- GVF-36 and GVF-42 gas inserts: delayed ignition and rollout. These units use a standing pilot with a SIT valve train that’s sensitive to pressure fluctuations. In Arlington Heights, we see pilot dropout spike every January when Nicor gas pressure dips during peak demand. We test incoming pressure at the appliance, clean the pilot orifice with a numbered drill set (never a wire brush, which oval the bore), and replace the thermopile if millivolt output sits below 325 mV under load. If the valve body is sticking, we source OEM SIT 820 Series valves through our Haven buying network rather than generic equivalents that lack the correct venting profile.
- Pre-2010 wood-burning fireboxes: refractory panel cracking at the rear wall joint. Gelco’s older CPF and APF lines used a single-piece rear refractory that expands toward the firebox floor. After fifteen winters of Arlington Heights freeze-thaw cycling, that joint opens enough to expose the steel wrapper. We camera-scan the wrapper for heat distortion, then quote replacement panels cut to pattern or a full FireGuard smoke chamber parge if the cracks have propagated into the throat. The camera doesn’t guess. Neither do we.
- GD-70 and GD-80 direct-vent gas units: failed pressure switches and condensate blockage. These mid-2000s direct-vents run a negative-pressure switch that clogs with combustion condensate, especially in Arlington Heights homes where the vent termination sits low on a north wall and collects freeze-thaw slush. We pull the switch, test against factory spec with a digital manometer, and if the diaphragm’s cracked we replace with the OEM Part # from our Gelco supplier. We also reroute condensate drain lines where the original slope traps water.
- Factory-built chimney systems: collar and storm collar separation. Gelco’s metal chimney systems use a twist-lock collar at the attic penetration that loosens after repeated thermal cycling. We’ve found this on four Arlington Heights ranches from the 1990s build wave, all with stained ceiling drywall below the chase. We reseat the collar with fresh high-temp sealant, add a proper storm collar with weep-cut orientation per NFPA 211, and document the repair with photos for your homeowner file under Haven Standard Clause 4.
- Gelco fireplace doors: tempered glass shatter from over-tightening. The OEM door kits for wood-burning units use 5mm tempered glass in a clip frame that homeowners often crank down after glass loosening. The clips stress-fracture the glass at the corners. We measure the opening, source replacement glass through our Famco supply line if Gelco OEM is back-ordered, and set clip torque to finger-tight plus a quarter turn. We also check the firebox for over-firing, since that’s what loosens the glass in the first place.
Our Gelco Fireplace Services Process

- 1
Call and schedule. A live person answers, day or night. We ask for the Gelco model number from the rating plate (usually inside the lower louver or on the firebox side) and what symptom you’re seeing. This lets Corrine or one of our techs pull the correct service manual before arrival.
- 2
NFPA 211 Level 2 inspection on arrival. Camera down the flue for wood-burning units, combustion analysis and gas pressure test for gas units. We photograph every finding. You see what we see on the tablet before we write the scope.
- 3
Written price, written scope, written warranty. Haven Standard Clause 1: the price is fixed before work starts. For Gelco jobs, we note whether we’re using OEM parts, quality aftermarket through our Haven buying network, or a mix. No surprises.
- 4
The repair. Our techs carry common Gelco wear parts - thermopiles, pressure switches, refractory panel templates - on the van. If we need to order, we tell you exactly when it arrives and reschedule before we leave.
- 5
Test and document. Gas units get a full combustion analysis with printout. Wood-burning units get a draft test and a final camera pull showing the completed repair. Everything goes into your photo record, archived under Haven Standard Clause 4.
- 6
Cleanup and follow-up. We haul away old parts unless you want them. The 365-Day Done Right Promise covers the labor and materials. If something’s not right, we make it right.

Why Arlington Heights Homeowners Call Level Two Chimney Arlington Heights for Gelco Work

We’ve been running camera inspections and sweeps in Arlington Heights since 2009, including plenty of calls near the shops and older colonials along Campbell Street. Corrine Halstead learned the trade at Apex Technical School in Manhattan and built this crew to work the same way: name the finding, give the number, move on.
Our techs carry Gelco-specific parts knowledge, not generic fireplace training. When a GVF-42 throws a code, we don’t guess. We test. Our buying network sources materials from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield - so if Gelco OEM is back-ordered, we have options that don’t leave you heating your living room with space heaters for three weeks.
The 365-Day Done Right Promise applies to every job. Haven Standard Clause 4 means your photo record is archived, not deleted. And Clause 1 means the price you sign is the price you pay.
FAQs
No. As an independent Gelco service provider, we use warranty-safe practices and OEM or equivalent parts. Gelco’s warranty covers manufacturing defects, not who performs the service. We document every part number and installation detail so you have records if a warranty claim ever arises. Call (331) 202-2419 if you need help navigating a claim - estimates are free.
Yes, in most cases. We stock common wear parts for GVF, GD, CPF, and APF lines, and our Haven buying network includes suppliers who specialize in discontinued Gelco components. When OEM is truly unavailable, we source quality aftermarket equivalents and tell you before installation. We don’t substitute without your written approval.
Replacement becomes the honest recommendation when the firebox wrapper is heat-distorted, the flue liner is compromised beyond spot repair, or repair costs exceed 60% of a new unit installed. We make that call only after camera evidence you can see, and we’ll tell you plainly when work can safely wait. Call (331) 202-2419 for an inspection - estimates are free.
NFPA 211 recommends annual inspection, with sweeping frequency based on use and fuel. A Gelco wood-burner burning seasoned oak in Arlington Heights typically needs sweeping every cord of wood burned, or annually if used as a primary heat source. We classify creosote by stage (Class I through III) during inspection and tell you exactly what we found.
Delayed ignition, incomplete combustion, and carbon monoxide risk increase. The SIT valves in GVF series units drift out of spec gradually; you may not notice until rollout scorches the surround or the CO alarm trips. We find it’s cheaper to tune the pilot assembly than to replace a stained mantel or worse. Call (331) 202-2419 to schedule - estimates are free.
