Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Kirkwood Residents Choose Us for Gelco Service
Gelco equipment shows up on a lot of Kirkwood roofs, and we know its habits. The stainless liner kits, the multi-flue caps, the top-sealing dampers, the crown coatings – each one fails in a recognizable way, and knowing that pattern saves guesswork.
We use OEM Gelco parts whenever they’re available, so fit and function match what the component was built for. When a part is discontinued or the model is older, we source quality aftermarket equivalents that meet or exceed the original specs. We’re an independent Gelco service provider, not manufacturer-affiliated or authorized by Gelco, and we’re upfront about it.
Our work in Kirkwood covers the whole chimney system, cap to firebox. We sweep, inspect and repair, so there’s no handoff to a second contractor when a cleaning turns up a cracked crown or a loose liner joint. Scheduling is simple and the estimate is free. Tell us what you’re seeing on the roof and we’ll take it from there.

Common Gelco Chimney Cleaning Problems We Solve in Kirkwood
Here’s what we actually find on Kirkwood homes and how each problem tends to start:
- Liner seams loosening after thermal cycling. Kirkwood’s freeze-thaw swings work stainless liner joints harder than a steady climate would. When seams loosen, flue gases can escape behind the liner, so we check every joint during a cleaning rather than just brushing past it.
- Hardened top-sealing damper gaskets. The rubber gasket on a Gelco top-sealing damper stiffens with age and stops sealing tight. In a humid St. Louis summer it also traps moisture, which drives both energy loss and water intrusion down the flue.
- Multi-flue caps rusting at the welds. Weld points are the first place a cap gives up. Humid summers and winter moisture push rust through those joints, and once a cap is compromised, rain and animals find the opening.
- Chimney crown coating cracking and delaminating. Crown coating on an exterior brick stack takes repeated freezing and thawing. Once it cracks, water gets into the masonry below and the damage widens through the next cold snap.
- Creosote and debris sitting against compromised components. A cleaning is when we find hidden trouble – buildup packed against a failing damper or a cap that’s no longer shedding water. Catching it at the sweep stage keeps a small fix small.
Gelco Service in Kirkwood: What Local Conditions Mean for Your Equipment
Kirkwood’s housing stock is what makes Gelco service here different from servicing the same components a few miles away. The brick Tudors, Colonial Revivals and four-squares near the historic downtown were built mostly between the 1910s and 1940s, and many still carry original clay tile liners, unlined rubble chimneys and exterior brick stacks that spall after decades of Midwest weather. When a Gelco cap or crown coating from that era is still on the roof, it’s original to the house. We see rusted multi-flue caps and cracked crown coatings on those downtown blocks in patterns that barely show up in neighboring newer suburbs, where the components are simply younger. That changes the conversation. A cleaning on one of these homes is also a look at how a decades-old component is holding up against the same freeze-thaw cycles that have been working on the brick since the house went up.
Gelco Models & Products We Service in Kirkwood
We service the Gelco components that sit on Kirkwood chimneys: Gelco stainless steel liner kits, Gelco multi-flue caps, Gelco top-sealing dampers and Gelco chimney crown coatings. Each one has its own wear pattern, and each one gets checked on its own terms during a visit.
Parts selection is where fit matters. We use OEM Gelco parts whenever available for a proper match, and when a model is older or discontinued we source quality aftermarket equivalents that meet or exceed the original specifications. We also weigh repair against replacement honestly. If a liner or cap can be safely repaired with a compatible part, that’s the call. If it can’t, we’ll explain in plain terms why replacement is the better long-term value.

AfterGelco Service Pricing in Kirkwood
Pricing depends on what the chimney actually needs, and we don’t quote over the phone without seeing it. A routine sweep and inspection sits at one end. Cap replacement, crown repair or waterproofing sits higher, because those involve exterior masonry work and materials. The written estimate sets the final price, and it’s free.

What we look at before pricing anything: the condition of the flue and liner, whether the cap is still shedding water, whether the crown coating has cracked through to the brick, and how much creosote has built up. Nothing gets recommended without evidence you can see for yourself, and we’ll tell you plainly when a job can safely wait. Call (866) 596-7310 for a free estimate.

FAQs – Gelco Chimney Cleaning in Kirkwood
Usually it depends on the welds. If rust has eaten through the weld points, the cap is no longer keeping water out and replacement is the practical answer. If the rust is surface-level, a repair with a compatible part may hold. We inspect before recommending either. Call (866) 596-7310 for an exact quote – estimates are free.
Freeze-thaw cycles are the main stress factor. Repeated expansion and contraction work on the seams and joints, and over years that loosening is what shortens a liner’s useful life. Humid summers add to it by promoting creosote degradation inside the flue.
A damper that no longer seals tight is the clearest sign, and you’ll notice it as a draft or as cold air moving down the flue when the fireplace is closed. A stiff or crumbling gasket is usually behind it. Water stains near the firebox are another indicator worth checking.
Yes, when the cap is sized and mounted correctly for the flue. Older brick stacks need a mounting approach that doesn’t crack the crown or the brick face, which is why we inspect the stack first. Call (866) 596-7310 for an exact quote – estimates are free.
Because the brick underneath has already been through decades of freezing and thawing. Hairline cracks in an older crown let water in, that water freezes, and the coating delaminates from the inside out. Repainting over it doesn’t fix that.
