Gelco Chimney Sweep Nationwide

Gelco Chimney Sweep in Houston: What to Know First

We’re an independent Gelco service provider in Houston, and a standard Gelco chimney sweep here typically runs $189 – $289, depending on the appliance and how much creosote has built up. Most Gelco sweeps in Houston take 45 to 90 minutes, and we carry the common wear parts for Gelco units on the truck so we don’t have to schedule a second visit for most jobs. The price you’re quoted before we start is the price on the invoice. Call (325) 750-6259 to book, and a live person answers.

This page is for Houston homeowners who own a Gelco fireplace, insert, or stove and want to know what a sweep actually involves for that specific brand. Hank Delano and our crew have been servicing Houston chimneys for over a decade, and we’ve cleaned enough Gelco units to know exactly where they collect soot and where they don’t. Tel me what you’re seeing, I’ll tell you what it costs to fix it.

How Gelco Products Fail – and How We Fix Them

Gelco makes solid, mid-range fireplace systems, but every brand has its patterns. Here’s what we see on Gelco units in Houston and what we do about it.

• Gelco direct-vent gas fireplace glass hazing. Gelco’s direct-vent units build a white film on the inside of the glass that homeowners mistake for soot. It’s actually mineral deposits from combustion byproducts bonding to the ceramic glass. On a sweep we pull the glass, clean it with a non-abrasive ceramic-glass cleaner, and check the gasket while it’s off. If the gasket is compressed flat, we say so before reinstalling.
• Gelco prefab firebox refractory panel cracking. The Gelco prefab fireplaces that show up in Houston track homes from the late 1990s through the 2000s use refractory panels that hairline-crack over time. Houston humidity accelerates it because the panels absorb moisture between burns and expand and contract. Small cracks get noted with a Level 1 or Level 2 inspection. Ones that expose the metal shell get a panel replacement quote and a written recommendation on whether it’s cosmetic or structural.
• Creosote you can’t see behind the Gelco smoke shelf. Gelco factory-built fireplaces sit shallow, and the smoke shelf is a ledge just above the firebox that catches creosote flakes. Homeowners see a clean firebox and assume the flue is fine. We find stage-two creosote on the shelf and in the first three feet of the flue on units that haven’t been swept in two or more Houston winters. That’s the area where a chimney fire usually starts, and it’s the first place we inspect with a mirror before the brush ever comes off the truck.
• Gelco gas log soot accumulation from closed dampers. We see Gelco vented gas logs in Houston where someone closed the damper halfway to keep the heat in. That restricts combustion air and creates lazy, sooty flames. The soot then gets drawn back into the logs and the firebox. A sweep fixes the immediate mess, but we also show the homeowner the damper position that runs clean, and we check the log set’s placement against the manufacturer’s pattern.
• Air-cooled flue clearances blocked by Houston attic work. Gelco air-cooled flues need air movement through the chase to stay safe. We’ve been on Houston jobs where someone’s added insulation or ran a cable line through the chase and blocked the air gap. That’s not always found on a routine sweep, but it’s checked on any Gelco inspection. If we find it, we document it with a photo and a written fix list.

Our Gelco Chimney Sweep Process

Everything happens in a set order, and the price is set before tools come off the truck. No surprise add-ons.

1. 1
   Written price first. We confirm the job type and the number of appliances, then hand you a written price. That’s the number, period.
2. 2
   Drop cloth and dust control. We lay down protection for your floor and furniture. We run a HEPA-filter vacuum throughout the sweep, and we tape off the firebox opening before the brush work starts.
3. 3
   Inspection before sweeping. We inspect the flue with a camera before we sweep it. This matters on Gelco units because the smoke shelf and the flue bends hide creosote that a top-down look won’t catch. If we find damage that changes the job, we stop and show you the footage on the spot.
4. 4
   Mechanical brushing and soot removal. We run the correctly sized brush for your Gelco flue diameter, not whatever’s on the truck. For gas units we use a non-wire brush to protect the flue liner. After the brush work, we vacuum the firebox, smoke shelf, and damper assembly.
5. 5
   Parts decision and repair, if needed. If we find a bad gasket, a cracked refractory panel, or a worn damper, we show you the photo or the part in hand and quote the fix separately. OEM Gelco parts when available and warrantied, quality aftermarket when an OEM part is backordered or discontinued. We never install a part and surprise you with the bill.
6. 6
   Post-sweep test and written guarantee. We fire the unit, confirm draft and flame pattern, and hand you a service write-up with what we found, what we did, and the one-year written guarantee on any repair we made. That’s the Garrison Standard.

What Gelco Chimney Sweep Costs in Houston

Here’s the honest pricing picture for Gelco work in Houston. These are our typical ranges, not bait numbers.

• Gelco gas fireplace or gas log sweep (glass and firebox cleaning included): $189 – $249
• Gelco wood-burning fireplace sweep with creosote removal: $229 – $289
• Gelco fireplace plus the attached flue sweep in a two-story Houston home: add $40 – $60
• Level 2 inspection (camera inspection, typically after a chimney fire, animal intrusion, or before a home sale): $350 – $500
• Refractory panel replacement on a Gelco prefab firebox: $275 – $650 depending on panel count and access

What moves the price: creosote severity, flue height, access from the roof versus the firebox, and whether a repair is flagged. A standard annual sweep is the low end. A unit that hasn’t been cleaned in five years is the high end. Call (325) 750-6259 and describe your Gelco unit. We’ll give you a written range before we schedule anything. Estimates are free.

Why Houston Homeowners Call Flint Chimney Co Houston for Gelco Work

We’ve been doing this as Flint Chimney Co Houston since 2002, under the same Garrison Partners banner that every Garrison Standard shop operates by. The rule on every job is the same: written price before work starts, written guarantee on every repair, and a live person on the phone around the clock. You call (325) 750-6259 at 2 a.m. and a person answers. No voicemail tree.

Our techs are background-checked and uniformed. They’ve worked on enough Gelco units in Houston to know the brand’s habits, and we also work with DuraFlex and HeatShield when a liner repair is the right call. That matters because some Gelco prefab fireplaces can’t accept a liner repair at all, and we’ll tell you that plainly instead of selling you something that shortens the life of the unit. The 365-Day Done Right Promise covers any repair we make for a full year. If a covered repair fails, we come back and fix it, no charge.
