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 Haverhill: What to Know First
We service Gelco fireplaces in Haverhill as an independent Gelco service provider, and a typical service call runs $149 to $329 depending on what’s actually wrong. Most Gelco jobs are done in one visit, since we carry the common wear parts for the gel-fuel and vented gas units that show up in the older homes here. If you’re holding a Gelco manual and wondering who still works on these, that’s us. Call (978) 724-7935 and Wendell or the crew will give you a straight answer before you spend a dime.

How Gelco Products Fail - and How We Fix Them
Gelco built a lot of fireplaces for the New England market during the 1980s and 1990s, and Haverhill still has plenty of them. Here’s what we actually find when we open one up:
- Gelco Vented Gas Log Sets (models like the Starlite and Golden Ember series): clogged burner ports from dust and carpet fibers. The flames get lazy and yellow on one side, and owners think the gas valve is bad. Nine times out of ten it’s a blocked port. We pull the burner, brush every port, and check the air shutter before we ever talk about replacing a valve.
- Gelco gel-fuel fireplace canisters with a sticky or frozen gel door latch. Gel fuel leaves a residue that builds up on the latch track over a season or two. Owners force it, bend the tab, and then the door hangs crooked. We clean the track, straighten or replace the latch, and show you how to keep it from happening again. Cheap fix, usually under $100.
- Cracked refractory panels in Gelco wood-burning fireplaces from Bradford and the riverfront neighborhoods. These homes are 80 to 120 years old, and the settling plus Haverhill’s damp winters cracks the panels eventually. A cracked panel is a firebox repair, not a chimney fire waiting to happen, but it does need replacing before the metal behind it starts rusting. We measure, order the panel, and come back once it’s in.
- Warped or corroded damper assemblies on Gelco fireplaces in unheated rooms. Damper iron rusts from condensation, especially in converted porches and back bedrooms that only get warmed when there’s a fire going. We replace the damper plate or the whole assembly depending on how far gone it is, and we always check the damper before we quote any other work.
- Gas valve and thermocouple issues on Gelco vented gas log sets that get left on overnight. The safety thermocouple eventually wears out. When it does, the pilot won’t stay lit, and the fix is a new thermocouple, not a new fireplace. We keep a few common Gelco-compatible thermocouples on the truck so the job’s done in one trip.
Our Gelco Fireplace Services Process
When you call about a Gelco fireplace in Haverhill, here’s how the job goes:
- 1
You call, a person answers. It might be Wendell. Tell us what the fireplace is doing or not doing, and we’ll give you a straight price range on the phone before we ever schedule the truck.
- 2
We show up with a real arrival window and call if anything slips. No four-hour waiting game. We get there, lay down drop cloths, and take the front of the fireplace apart carefully to see what’s actually wrong.
- 3
We diagnose with the camera when it matters. We carry a small inspection camera for tight spots behind the firebox and inside the venting. If there’s a crack or a blockage you can’t see from the front, we’ll show you the footage and explain what it means in plain English.
- 4
We give you the price before we fix anything. The number we quote on your doorstep is the number on the invoice. No markup surprises, no “I found something else while I was in there” games. If it doesn’t need doing, we’ll tell you that too.
- 5
We do the work, then test it in front of you. Gas fires lit, gel latch working, damper opening and closing smooth. You see it work before we pack up.
- 6
We stand behind it for 90 days. Every Gelco service call we do carries our 90-Day Done Right Promise in writing. If the same problem comes back, one call brings us back at no charge.
What Gelco Fireplace Services Costs in Haverhill
Here’s what we charge for the Gelco work we see most in Haverhill:
- Gelco gel-fuel fireplace service (cleaning, latch fix, canister check): $89 to $149
- Gelco vented gas log set service (burner cleaning, port unclogging, pilot/thermocouple): $149 to $229
- Damper repair or replacement on a Gelco fireplace: $129 to $289 depending on the assembly
- Refractory panel replacement for Gelco wood-burning fireboxes: $200 to $400 including the panel and labor
- Gas valve replacement on Gelco vented gas logs: $250 to $400 depending on the valve
The spread usually comes down to parts and access. A fireplace on the first floor with an easy-to-reach firebox is faster than one in a finished basement with a stone surround we have to work around carefully. If you’ve got a written estimate from another shop, show it to us and we’ll give you a free second opinion. Estimates are free, and there’s no trip charge if you’re inside the county. Call (978) 724-7935 and we’ll talk through it.

Why Haverhill Homeowners Call Top Hat Chimney for Gelco Work
We’ve been working on fireplaces in Haverhill since 1999, and Wendell Pike has been in enough of these old chimneys to know what a Gelco firebox looks like when it’s been loved, neglected, or stuffed with Christmas wrapping paper. We’re not a national outfit that sent a different person last year. Wendell owns the company, puts his name on the work, and runs into you again at the hardware store on Washington Street. We also service DuraFlex liners and HeatShield repair systems, which means when a Gelco fireplace is actually a liner problem higher up the chimney, we handle that too without subbing it out. Fair price, real name, and a 90-day promise on every job.
FAQs
No. Your Gelco fireplace warranty is from the manufacturer, and using a licensed, insured chimney service for maintenance or repair does not void it. We use correct-fit parts and we never take shortcuts that would put your warranty at risk. If you’ve got a warranty question, bring us the paperwork and we’ll read it with you and tell you exactly what’s covered before we do anything.
Most of them, yes. Burner tubes, thermocouples, damper plates, refractory panels, and gel canister latches are all still available, either as genuine Gelco parts or quality aftermarket pieces built to the same spec. When the only route is aftermarket, we tell you that upfront and show you the part before we install it. If a part has been discontinued entirely, we’ll say so and figure out the next move without pressuring you into a replacement.
For most Gelco service calls, we can get to you within a few days, often sooner in the spring and summer. Winter heating season fills up faster, especially after the first real cold snap. If it’s a safety issue like gas smell or a visible crack in the firebox, tell the person on the phone so we can prioritize you. Call (978) 724-7935 and we’ll give you the next open window.
That depends on what’s wrong. A thermocouple, a sticky gel latch, a clogged burner port, or a warped damper is a repair, plain and simple, and most of those run between $89 and $400. If the firebox is rusted through or the casting is cracked in a way that compromises the structure, replacement starts to make more sense. We’ll show you the camera footage and give you our honest recommendation. If it doesn’t need replacing, we won’t sell you a replacement.
Yes, once a year, burn or no burn. Gas fireplaces still produce moisture and acidic condensation inside the flue, and over time that eats away at the liner. In Haverhill, with our wet winters and older homes, we see flue degradation in gas fireplaces happen faster than people expect. A yearly check catches it before it becomes a real problem.
