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 Creve Coeur, MO
Hawk Chimney Sweep provides independent Gelco service across Creve Coeur, from cap replacement and damper repair to crown work on the masonry chimneys these homes were built around. The one thing that makes our Gelco work different here is the starting point: most Creve Coeur fireplaces sit unused for years, so the real work is usually animal debris, a seized top-mount damper and a cap that no longer seals, not heavy soot. We know the hardware because we work on it, and we have no affiliation with or authorization from the manufacturer. Call (866) 596-7310 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

Why Creve Coeur Residents Choose Us for Gelco Service
Homeowners in Creve Coeur tend to call us for the same reason: they’ve been told something alarming about their chimney and they want a second set of eyes on it. We’re an independent shop. That means we look at the cap, the damper, the flue tile and the crown and tell you plainly what’s failing and what’s fine. If the flue is sound and the cap just needs a correctly sized stainless unit, that’s what we’ll tell you.
Our technicians have up to 12 years of experience with Gelco multi-flue stainless caps, single-flue stainless caps, top-mount damper units and custom-fabricated caps for oversized masonry flues. We repair, install and service Gelco equipment using quality parts that fit it – exact-fit stainless where the sizing matches, professional-grade aftermarket stainless where it doesn’t. We don’t carry or stock parts, and we don’t claim to be a Gelco dealer. What we do is fit the right part to the flue that’s actually there.
Scheduling is straightforward. We answer 24/7, and dispatch runs 7am to 7pm, Sunday through Friday. Sweeps are booked, so you’ll know the day before anyone comes out.

Common Gelco Chimney Cleaning Problems We Solve in Creve Coeur
- Screen mesh packed with nesting and leaf litter. Stainless Gelco caps on 1960s to 1980s Creve Coeur masonry flues are often choked with squirrel nesting and leaf litter, and draft dies before a fire is even lit. On wooded lots, that happens faster than most owners expect.
- Corroded, loosened cap legs and screws. Mounting hardware on older Gelco installations corrodes and works loose through St. Louis freeze-thaw cycles. A shifted cap leaks water; a loose one leaves in wind.
- Stiff, seized top-mount damper gaskets and cables. After long off-seasons the gasket hardens and the cable stops moving cleanly, so the damper neither seals nor opens all the way. That’s a draft problem in winter and an air-loss problem the rest of the year.
- Custom Gelco caps that no longer sit flush. Caps sized for original clay-tile flues lose their seal once the tile spalls or the crown cracks, leaving gaps at the top for water and animals. In Creve Coeur’s humid, freeze-thaw climate, that’s a slow-motion problem, not a sudden one.
- Damper and cap problems hiding a real flue issue. Sometimes the damper is fine and the cap is fine, and the actual trouble is a cracked liner behind them. We check the whole flue before recommending parts, because replacing a cap over a failing liner fixes nothing.
Gelco Service in Creve Coeur: What Local Conditions Mean for Your Equipment
Creve Coeur’s mature lots are heavily wooded, and that changes what a chimney call actually looks like here. Chimney tops collect raccoon, squirrel and bird nesting far more than they collect soot, and missing or rusted caps are the single most common finding on these 1960s to 1980s brick homes. Walk a street like Ladue Road through the older sections and you’ll see the pattern clearly: deep tree canopy, brick chimneys with original clay-tile flues, and caps that have taken thirty or forty seasons of weather. For a Gelco-style installation, that means the failure usually starts with the screen and the mounting legs, not the interior of the cap.
The local climate adds to it. St. Louis-area winters are cold enough for steady fireplace use from November through March, and the humid freeze-thaw cycle works on exterior brick, mortar crowns and dampers year round. Summer humidity rusts hardware. Winter freeze cycles crack crowns. Long off-seasons let creosote and nests accumulate quietly. A Gelco cap that was fine when it went on may be a liability by the time you’re ready to light the first fire of the season.
Gelco Models & Products We Service in Creve Coeur
We service the full range of Gelco-branded chimney hardware found on Creve Coeur masonry chimneys: multi-flue stainless caps, single-flue stainless caps, top-mount damper units, and custom-fabricated caps built for oversized masonry flues. Each one gets the same treatment. We measure the actual flue opening, check the tile and crown condition, and then pick a part that fits the flue as it sits today, not as it was drawn in 1972.
For caps and top-mount dampers, exact-fit stainless replacements outlast hardware-store galvanized units by a wide margin in this climate. OEM Gelco where the sizing matches the existing flue; quality aftermarket stainless where it doesn’t. If you want to see how we approach brand-specific work, our Gelco page covers the wider picture.

AfterGelco Service Pricing in Creve Coeur
Pricing here is set per job by the written estimate, and the estimate is free. What drives the number is the scope: a straightforward cap swap on a sound single-flue masonry chimney sits at the low end, while a multi-flue stainless replacement combined with damper repair and crown work runs higher. Animal debris removal and a Level 2 camera inspection add time. Custom-fabricated caps for oversized flues cost more than stock sizing.

Here’s what the estimate covers: the inspection findings, the parts required, and the labor, in writing, before anyone books the work. We won’t quote a rebuild when a cap and damper will do, and we won’t quote a cap when the flue tile behind it has spalled. If the work can safely wait, we’ll say so. Call (866) 596-7310 for an exact quote – estimates are free.

FAQs – Gelco Chimney Cleaning in Creve Coeur
It usually needs replacing. Once the screen is gone and the steel is rusted through, patching the mesh doesn’t restore draft control or keep animals out – a correctly sized stainless unit does. We check the mounting legs and the flue tile first, because a new cap on a cracked crown just traps water. Call (866) 596-7310 for a free estimate.
The gasket and cable stiffen during the off-season, and humidity accelerates it. In Creve Coeur’s humid summers, a damper that sat closed from April to October often won’t move cleanly by November. We service the existing unit when the cable and gasket can be brought back, and recommend replacement when they can’t.
A Level 2 inspection is the right call for a fireplace that’s sat unused or had any change to the flue system. It includes camera work, which is how you find a cracked clay-tile liner before the first fire. A Level 1 is a visual check appropriate for a chimney in regular use with no known problems.
Yes, and it’s the most common thing we find on mature lots. Squirrels, raccoons and birds treat an open or damaged chimney top as shelter, and nesting packs the flue until draft suffers. A sound cap with intact screen is the fix, installed correctly so it stays put.
It does. A failed crown lets water into the masonry, which rusts cap hardware and warps damper components from the inside. Crown repair before cap replacement is often the honest sequence. Call (866) 596-7310 for a free estimate on both.
