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 Northampton: What to Know First
We service Gelco fireplaces throughout Northampton, PA as an independent provider, with most diagnostics completed within a few days of your call and most repairs done same-week once we’ve seen the unit. The price we quote on the phone is what you pay, assuming the problem is what you described, and if we open things up and find the job is simpler than expected, we charge less, not more. That’s how Wendell Pike has run Top Hat Chimney since 1999.
This page is for Gelco owners in Northampton who want a straight answer about their fireplace: what’s actually wrong, what it costs, and whether the fix can wait. If you’ve got a Gelco unit that won’t light, won’t stay lit, or smells odd when it runs, call (484) 859-1367 and we’ll talk it through first.

How Gelco Products Fail - and How We Fix Them
- Pilot assembly drop-off on Gelco’s vent-free lines. On Gelco’s Vent-Free gas log sets, the pilot tube has a narrow bend that collects soot faster than most brands if the air shutter drifts even slightly rich. Symptom: the pilot lights but won’t hold after you release the knob. The factory thermocouple tests fine, which sends a lot of techs chasing the wrong part. We’ve learned to look at the pilot orifice itself first, which is usually clogged with a fine gray powder. Fix is a proper cleaning and the air shutter reset, not a new valve.
- Ceramic log degradation on Gelco’s 24-inch vented sets. Gelco’s older vented logs used a ceramic fiber that gets brittle after 8 to 10 seasons of regular burning. Owners in Northampton notice the front log cracking along its bottom edge, sometimes shedding fragments into the burner pan. It’s not dangerous by itself, but it changes the flame pattern and can trap gas. We can replace individual logs rather than the whole set, and we’ll tell you honestly when the set still has life in it.
- Thermopile voltage sag on Gelco’s direct-vent inserts. Gelco’s direct-vent inserts run a thermopile that degrades slowly and unevenly, especially in Northampton’s damp spring months. The fireplace works fine in November, then starts dropping the main flame in March. The real cause is usually a thermopile putting out 250 millivolts instead of the 450-plus it should, not a bad gas valve. We test the actual millivolt reading, not just “is it warm,” and replace the thermopile rather than quoting you a valve you don’t need.
- Shutter misalignment from the factory on some Gelco burner pans. A handful of Gelco gas log burners left the factory with the primary air shutter a touch loose, which lets the burner run yellow and sooty after a year or two of use. The fireplace still heats, but it’s depositing short, hard carbon flakes into the firebox and up the chimney. We’ve seen this on units that were never moved or bumped, so we know it’s the shutter walking itself loose. We realign it, set the gap, and test with the doors closed.
- Glass gasket flattening on Gelco direct-vent models with high hours. The glass gasket on a Gelco insert gets pressed flat after years of door openings, and the first thing you’ll notice is a faint exhaust odor in the room when the fan is off. That’s the glass seal weeping combustion byproduct, not a chimney problem. We replace the gasket with the correct density material and adjust the latch tension, and the smell is gone the same day. This is the fix nobody tells you about because it’s a $70 part and an hour of labor instead of a new insert.
Our Gelco Fireplace Services Process
- 1
You call (484) 859-1367. A live person answers, day or night. You describe your Gelco fireplace symptoms in your own words, and we give you an honest idea of what it likely is and what it likely costs.
- 2
We show up on time. Wendell or one of his crew arrives in a real window, uniformed and background-checked, and if we’re going to be late, we call.
- 3
We diagnose with tools, not guesses. Millivolt readings, gas pressure checks, flue condition, burner pattern, gasket seating. On a Gelco, we’re checking the specific failure points we listed above before anything else.
- 4
We explain what we found in plain words. You get the repair decision explained in a way you can repeat to your son-in-law. If the work can wait, we say so and write nothing up.
- 5
We do the work with the right parts. OEM Gelco when it matters for warranty or fit, quality aftermarket where it performs identically and costs less. We’ll tell you which is which and why.
- 6
We test it, explain it again, and you get the 90-Day Done Right Promise in writing. If anything we touched isn’t right, one call brings us back free.

Why Northampton Homeowners Call Top Hat Chimney for Gelco Work
Wendell Pike has been at this since 1999, and his name and license number are on every invoice. When a Gelco owner in Northampton calls Top Hat Chimney, the person who answers the phone is the same person who’ll be standing in front of the fireplace. Not a call center in another state.
We know how a Gelco actually fails, which is why we don’t waste your money chasing the wrong part. And if your unit needs something beyond what Gelco makes, we work with DuraFlex and HeatShield too, so we’re not trying to sell you a new fireplace when a liner or a refractory panel is the right fix.
The 90-Day Done Right Promise is stamped on every job, no exceptions. If it does not need doing, Wendell will tell you. If it does, he’ll get it done right.
FAQs
No. Independent servicing does not void a Gelco warranty, and if you’re still within it, we’ll help you submit the repair to the manufacturer. We install OEM Gelco parts when warranty coverage is a factor, and we’ll be straight with you about when aftermarket makes more sense.
The most common cause on Gelco units is a thermopile that has lost its millivolt output, especially on direct-vent inserts that get heavy winter use. Second is a sooted pilot orifice on vent-free sets. Both are fixable in one visit, and we test before we quote.
Usually within a few days for diagnostics, and most repairs go same-week once we’ve seen it and ordered parts. If we have to wait on a specific Gelco part, you’ll know the timeline before we start.
Most of the time, yes. Gelco fireboxes and burners are simple, durable units, and a $200 thermopile or gasket fix beats a $2,000 replacement. When we think replacement is the honest call, we’ll tell you, but we won’t upsell you to a new unit to make a quota.
Yes, and it’s common. We scan the existing installation, verify clearances and venting, and repair what’s wrong. We’re an independent Gelco service provider, not a sales team for one brand, so we work on what’s in your home.
