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 Chimney Cleaning in Costa Mesa, CA | Limestone Chimney Sweep
We provide independent Gelco chimney cleaning and repair across Costa Mesa’s 92626, 92627, and 92628 ZIP codes. Most of the Gelco work we do here involves fireplaces that have barely been used in years, which means the problems we find are less about creosote and more about what the coastal air has quietly done to the flue, damper, and cap. If you own a Gelco fireplace in Costa Mesa, call (855) 341-5439 for a free estimate.
We’re Gelco sales & service specialists in the sense that we know these units inside and out – not because we carry a manufacturer badge, but because we’ve opened enough of them across Orange County to know exactly where they fail.
Why Costa Mesa Residents Choose Us for Gelco Service
Limestone Chimney Sweep handles three service lines: chimney sweeping, chimney repair, and dryer vent cleaning. That matters for Gelco owners because most cleaning crews will hand you a report and walk away. We carry the materials to fix what we find. That’s the difference between a brush pass and an actual resolution.
Warren Tilsley, our owner, started with HVAC and sheet metal training at Irvine Valley College before spending years working alongside experienced sweeps all over Orange County. He’s seen enough Costa Mesa fireplaces to know that a Gelco unit from 1962 behaves differently than one from 1988, and he trains our techs to look for those patterns. We’re also part of the broader Costa Mesa service area our company covers, so we’re local, not a crew driving down from LA for the day.
We stock OEM-equivalent Gelco dampers, caps, and firebox components where they’re still available, and when a part has been discontinued we use aftermarket replacements that meet or exceed the original spec. We’ll tell you straight if a repair will restore safe function or if the unit is done. No pressure to replace what can be fixed.

Common Gelco Chimney Cleaning Problems We Solve in Costa Mesa
- Cracked or spalled clay flue tiles. Costa Mesa’s salt-laden onshore air works its way into masonry over decades. The 1950s and 60s Westside homes often have original clay tile flues where the mortar joints have eroded and the tiles themselves have begun to spall. We find this on Gelco installations that haven’t been touched since Lyndon Johnson was president.
- Rusted dampers and seized hardware. The marine layer keeps humidity high even in summer. We regularly open Gelco fireplaces here and find dampers rusted wide open or frozen shut – sometimes so corroded the handle snaps when you try to move it. This is a coastal thing. You don’t see it as often in Anaheim.
- Undersized flues on gas-converted Gelco units. Many original Gelco fireplaces in Costa Mesa were wood-burning when the house went up, then got a gas log set dropped in sometime in the 90s or 2000s. The flue was sized for wood, not for the sustained lower-temperature burn of gas, and nobody thought to reline it. That’s a draft and condensation problem waiting to happen.
- Corroded chimney caps and flashing fasteners. Salt air eats plated steel. On Gelco installations across Costa Mesa’s Eastside and Westside, we find cap screens rusted through and flashing nails that have turned to orange dust. Water gets in, and the masonry pays for it.
- Light-use creosote that’s deceptively dangerous. Costa Mesa’s mild climate means fireplaces get used maybe a dozen times a year. That sounds benign, but light intermittent use lets each season’s creosote settle and harden into a glossy, baked-on layer. It’s harder to remove than the fluffy stuff you’d get from heavy burning, and it still burns hot if it ever ignites.
Gelco Service in Costa Mesa: What Local Conditions Mean for Your Equipment
Here’s what makes Costa Mesa different from Gelco in Newport Beach or Santa Ana, and what Gelco owners here need to understand. Costa Mesa’s Westside 1950s tract homes often have original Gelco clay-tile flues with cracked mortar joints and rusted dampers that go unnoticed because the mild coastal climate means fireplaces see light, intermittent use. The creosote and moisture damage accumulate silently for years. Nobody notices because nobody is looking. Our technicians routinely find gas log sets installed without a proper liner in these homes – a condition that’s easy to miss without a camera inspection, and one that can send combustion gases into the house rather than up the flue. On a recent job in a 1956 Westside tract home off Plumer Street in 92627, we inspected a Gelco Heat-Circulating fireplace with a gas log set and found the original clay flue tiles had cracked mortar joints and a damper rusted wide open. After a Level 2 camera inspection revealed a missing liner, we repointed the joints, installed a proper liner, and replaced the damper, restoring safe draft and giving the homeowner a clear maintenance plan.
A clean chimney isn’t a luxury – it’s just the part of your house you can’t see doing its job right.
Gelco Models & Products We Service in Costa Mesa
We work on the full Gelco lineup we encounter most in Costa Mesa homes and provide Gelco service in Huntington Beach: the ZC Series zero-clearance fireplace, common in 1980s and later construction on the Eastside and South Coast areas; the Heat-Circulating Series, which we see constantly in 1950s and 60s Westside tract homes; vented and vent-free Gelco Gas Log Sets; and Gelco Direct-Vent Inserts retrofitted into older masonry openings. For each of these, we follow the same approach: OEM parts where Gelco still supplies them, and quality aftermarket equivalents when they don’t. We keep common damper assemblies, cap screens, and firebox components on the truck for the Gelco units we see most in this city, which means most Costa Mesa repairs don’t wait on a parts order.

AfterGelco Service Pricing in Costa Mesa
Gelco chimney cleaning in Costa Mesa typically falls between $229 and $399 for a standard sweep, with Level 2 camera inspections running $299 to $499 when we’re investigating a specific concern. Repairs are quoted separately after we show you the camera footage. What drives cost here is usually condition, not square footage: a 1958 Gelco with spalled tiles and a seized damper costs more than a clean 1990s unit because we’re restoring, not just brushing. Every estimate includes the inspection, the cleaning, and a written report with photos. Call (855) 341-5439 and we’ll give you a real number, not a vague range.

FAQs – Gelco Chimney Cleaning in Costa Mesa
Once a year is the safe answer, even if you only burn a few times each season. In Costa Mesa, the real reason for annual service isn’t creosote volume – it’s catching what the salt air and humidity are doing to your flue tiles, damper, and cap before small corrosion becomes a liner replacement. Call (855) 341-5439 to schedule.
Yes, and in Costa Mesa specifically, the inspection matters more than the cleaning. Gas logs produce less visible soot, but undersized or unlined flues on converted Gelco units can allow combustion byproducts to collect and damage the masonry. We camera-inspect every gas-converted Gelco we touch. If you’re not sure what your flue looks like inside, that’s the exact reason to book a Level 2 inspection.
Rust streaks down the chimney exterior, a cap that rattles in the wind, visible holes in the screen, or water staining on the ceiling near the fireplace. In Costa Mesa’s salt air, plated steel caps fail faster than they would inland, and a failed cap is the first domino for every other moisture problem, unlike the conditions we see providing San Joaquin Hills Gelco service. We can replace it with a properly fitted unit before the damage spreads.
Almost always repairable. A stuck-open damper is typically a rusted hinge, a broken handle bracket, or corrosion at the frame – not a reason to replace the whole fireplace. We stock replacement damper assemblies for the Gelco units we see most in Costa Mesa and can usually resolve it in one visit. Call (855) 341-5439 and we’ll tell you what we find.
We do. Costa Mesa’s marine layer and onshore moisture make waterproofing one of the highest-value services for older Gelco masonry chimneys. We apply a vapor-permeable sealant that keeps rain and salt air out while letting moisture already inside the masonry escape. It’s typically a same-day job once the flue is clean. Call us for a free estimate.
