Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Liner & Rebuild in Ellicott City: What to Know First
We provide independent Gelco chimney liner and rebuild service in Ellicott City, with most Gelco liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. Typical Gelco stainless steel liner jobs run $2,800-$4,500; partial rebuilds start around $3,200 and scale with height and access. We don’t quote over the phone without seeing the flue - the flue doesn’t lie, we just translate what it’s telling you.
This page is for Ellicott City homeowners who know they’ve got a Gelco liner or are unsure what brand is up there, and need someone who won’t treat it as generic pipe. If you’re seeing water in the firebox, smelling smoke in upstairs rooms, or staring at a home inspection report that says “Gelco liner - evaluate,” call us at (410) 305-7884. A live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco UltraPro flexible liners in Ellicott City’s older stone chimneys. We’ve replaced dozens of these in the historic district near Main Street where the flue gasses cool too fast in tall, uninsulated shafts. The UltraPro’s 316Ti alloy holds up, but the flex sections flatten at offset transitions after 15-20 years of thermal cycling. We pull a new Gelco rigid or switch to DuraFlex if the offsets are severe. Camera inspection first - no guesswork.
- Gelco Pro-Fit oval liners retrofitted into square flues in 1990s split-levels off Route 40. These were popular for their easy insertion, but the oval-to-round adapters crack at the weld seam where creosote concentrates. We see this every burning season. Our fix: cut out the adapter, inspect the surrounding masonry for pyrolysis damage, and install a proper Gelco oval termination or upsize to a round liner if the flue allows.
- Gelco stainless top plates and rain caps on homes near the Patapsco River valley. The humidity here is higher than the Piedmont average, and we’ve found Gelco caps with premature base-rust at the 8-year mark, not the 15 the specs suggest. We replace with marine-grade Gelco hardware or step up to Copperfield if the exposure is severe. Same-day on caps if we’ve got the diameter in the truck.
- Gelco liner collars pulled loose by freeze-thaw in Ellicott City’s clay-heavy soil zones. The ground shifts, the chimney leans a hair, and the liner collar at the thimble separates. Smoke spills into the wall cavity. We reseat with a Gelco compression collar and add a HeatShield cerfractory seal if the surrounding brick is friable. Done right - and we stand behind it.
- Gelco smooth-wall liners in oil-to-gas conversions. When a homeowner switches from oil to natural gas, the lower flue temperature changes the condensation pattern. Gelco’s smooth-wall sheds condensate better than corrugated, but if the sizing is off by even one diameter, water pools at the base and rusts out the cleanout tee. We calculate the new BTU load and either resize the Gelco or recommend a HeatShield resurfacing if the existing liner is structurally sound.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We book a two-hour window in Ellicott City - typically within a week, sooner if there’s an active leak or backdraft hazard.
- 2
Level-2 camera inspection. Our tech runs a camera the full length of the Gelco liner, photographs every joint, offset, and termination. You see the images on a tablet while we’re still on the ladder. A plain-English verdict follows: repair, replace, or monitor.
- 3
Parts decision. If it’s a Gelco liner replacement, we check OEM availability against DuraFlex or HeatShield alternatives. We explain the trade-off - warranty coverage, wall thickness, Ellicott City’s freeze-thaw exposure - and you choose. No surprises on the bill.
- 4
The rebuild or reline. Background-checked, uniformed technicians complete most Gelco liner replacements and partial rebuilds in one visit. Full rebuilds may need a second day for curing. We protect your floors, haul away the old liner, and run a combustion test before we leave.
- 5
Documentation and guarantee. You get photos, a written report, and the 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.

FAQs
No - but only if the work is done with Gelco-compatible parts and practices. As an independent Gelco service provider, we use OEM or equivalent-grade components and document the installation per manufacturer guidelines. If your liner is still under Gelco’s 20-year or lifetime warranty, improper DIY repair or generic hardware can void it. We check your warranty status before we start and keep the paperwork clean. Call (410) 305-7884 and we’ll verify it together.
Most common Gelco diameters and fittings are in our Ellicott City warehouse or on our trucks. For specialty sizes - the older 5.5-inch oval, for example - we source directly and typically have them within 3-5 business days. If your heat is down and it’s urgent, we’ll discuss a DuraFlex interim solution that meets code and can be swapped later without double labor. A square deal: no surprises on the bill.
The camera tells the story. Surface rust or a loose collar is repairable. Multiple perforations, separated seams, or a liner that has detached from the top plate means replacement. We show you the footage and explain which category you’re in - and if the repair can safely wait a season, we say so plainly. Nothing is recommended without camera evidence you can see for yourself.
A compromised liner lets heat, sparks, and carbon monoxide reach the surrounding masonry and framing. In Ellicott City’s older homes with balloon framing, that risk is real and specific. Creosote can also leak through liner gaps and ignite in the chimney cavity. We don’t scare-sell, but we don’t soft-pedal physics either. If the camera shows a breach, we recommend scheduling before the next burn. Call (410) 305-7884 for a free inspection.
Yes - DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield are all in our regular rotation. If your home has a mixed system (Gelco liner with a Famco cap, for instance), we service it as a unit rather than forcing mismatched parts. Russell Haines and our crew have handled every major brand combination in Howard County. The right part for the job, not whatever’s cheapest.
