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 gas inserts (GVST and GVFT series): intermittent pilot ignition failure. The SIT valve modules on these units tend to throw soft-lock errors after 6-10 years, especially in Norristown’s older homes where voltage fluctuates on 1920s branch circuits. We test flame signal strength in millivolts, replace the valve with an OEM SIT 820 or a Robertshaw equivalent rated for the same manifold pressure, and verify shutdown timing before we leave.
- Gelco wood-burning prefab fireplaces (Tempwood and Heat-a-Lator cross-labeled units): refractory panel cracking at the smoke chamber joint. The factory refractory shrinks differently than the surrounding steel wrapper after repeated thermal cycling. We measure the gap with a feeler gauge, source Gelco-specified panels or HeatShield Cerfractory foam when the OEM part is back-ordered, and document the repair with before-and-after photos under Haven Standard Clause 4.
- Gelco direct-vent gas fireplaces: condensate line blockage causing corrosion of the burner pan. Norristown’s freeze-thaw cycles push masonry debris and leaf matter into exterior termination caps, backing water into the firebox. We rod the condensate line, inspect the burner pan with the camera, and replace rusted components with DuraFlex or Gelco OEM parts depending on warranty status and availability.
- Gelco fireplace dampers (original equipment on many 1990s-2000s installs): cable seizure or throat plate warping. The galvanized cable housings collect creosote dust that hardens into a binding paste. We don’t lubricate and hope - we remove the damper assembly, clean the track, and install a replacement with a stainless cable if the throat plate has lost more than 1/8-inch of flatness.
- Gelco chimney caps and chase covers: galvanized steel rust-through at the drip edge. Gelco’s standard galvanized caps last 12-15 years in Pennsylvania’s acid-rain corridor. We fabricate replacement chase covers from 24-gauge stainless or copper through our Famco and Copperfield supply chain, sized to the exact chase dimension, and seal with a high-temp silicone rated to 400°F.
Our Gelco Fireplace Services Process

- 1
Call and schedule. A live person answers, checks our Norristown route calendar, and books a window. You’ll get a text when your tech is en route.
- 2
Camera-scan inspection. We run a chimney camera per NFPA 211 Level 2 standards, document the flue liner, smoke chamber, and firebox condition, and show you the footage on site.
- 3
Written diagnosis and price. Before any tool touches your Gelco unit, you receive a written scope, a written price, and a written warranty. Haven Standard Clause 1: have it in writing.
- 4
Parts decision. We check Gelco OEM availability against our network stock of DuraFlex, HeatShield, and quality aftermarket equivalents. If your unit is under warranty, we use OEM. If not, we quote both options and explain the trade-off.
- 5
Repair and test. The work is performed by a background-checked, uniformed technician. Gas units get a combustion analysis; wood units get a draft test and creosote classification.
- 6
Documentation and follow-up. You leave with photos, camera footage, the written invoice, and the 365-Day Done Right Promise. Our archive holds your record under Haven Standard Clause 4.

Why Norristown Homeowners Call Emberly Chimney Cleaners Norristown for Gelco Work

We’ve run camera inspections through Norristown chimneys since 2009 - more than 38,000 documented records, every one with a written price before work started. Corrine Halstead’s crew knows the local housing stock: the converted twins near Elmwood Park with their undersized flues, the brick colonials off Main Street with original Gelco inserts now past their twenty-year mark. We don’t sell on fear. We show you what the camera found, name the price, and let you decide what to fix now and what can wait. The camera found it. The report names it. The price is written down. That’s where we start. Our materials come through Haven’s buying network - DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, Copperfield - so your price reflects actual cost, not markup theater. And if we don’t get it right, the 365-Day Done Right Promise means we come back and make it right.
FAQs
No, if the work is performed by a qualified technician using correct parts and procedures. As an independent Gelco service provider, we follow manufacturer specifications for clearances, venting, and component replacement. We document every step so you have a record if a warranty question ever arises. Call (484) 552-9695 if you’d like us to review your warranty status before booking.
Most common parts - SIT valves, refractory panels, pilot assemblies - ship within 3-5 business days through our network. Some discontinued Gelco series require fabrication or cross-referencing to HeatShield or DuraFlex equivalents, which can add a week. We stock high-failure items for Norristown’s most common installs and will tell you the exact lead time in your written estimate.
Replace when the firebox or heat exchanger is cracked beyond safe repair, or when parts are obsolete and no quality equivalent exists. Repair when the issue is isolated to a replaceable component - damper, burner, refractory - and the chassis is sound. We’ll show you the camera footage and give you both numbers so you can decide. Call (484) 552-9695 for a free inspection.
Annually, per NFPA 211 and most manufacturer guidelines. Even clean-burning gas units accumulate debris in burners, develop micro-leaks in fittings, and drift out of proper combustion ratios. Norristown’s hard water also scales pilot orifices faster than surrounding counties. We find it’s cheaper to tune than to replace a heat-damaged valve.
Class III creosote builds up - the hard, glazed kind that can’t be brushed out with standard tools. It restricts draft, accelerates liner corrosion, and raises chimney fire risk. In Norristown’s tight chimney flues, we’ve seen 1/4-inch deposits form in a single burning season. A Level 2 inspection catches it before it becomes a removal job. Call (484) 552-9695 to schedule - estimates are free.
