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.
Gelco Chimney Cleaning & Sweep in Severna Park: What to Know First
As an independent Gelco service provider, we clean, sweep, and inspect Gelco chimney systems throughout Severna Park, with most jobs scheduled within a few days and completed in a single visit. A standard Gelco chimney sweep and Level 1 inspection runs $180-$280; if your flue needs a Level 2 camera inspection, plan on $280-$420. We give you the price before we start, and that is the price on the invoice.
This page is for Severna Park homeowners who heat with wood or gas and know they have a Gelco cap, Gelco liner, or Gelco damper on their chimney. Maybe you bought the house with it already in place, or a previous installer specified Gelco parts. Either way, you need someone who recognizes the hardware without squinting at it, and who will not try to sell you a full replacement when a sweep and adjustment is all you need. Call (443) 464-2560. A live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco chimney caps with the mesh screen design collect pine needles and leaf debris from Severna Park’s mature oak canopy faster than solid-cap competitors. The mesh corrodes at the weld points after 12-15 years of salt-air exposure off the Chesapeake, and once it sags, squirrels pull it loose. We remove the cap, assess whether the screen can be re-welded or needs replacement, and reinstall with stainless fasteners that outlast the original hardware.
- Gelco top-sealing dampers in the Pre-Set series develop cable fray where the control line exits the firebox through a sharp-edged thimble. Homeowners notice the handle gets stiff, then snaps. We replace the cable with a Gelco OEM spec or a heavier-duty aftermarket equivalent, and we deburr the thimble edge so it does not happen again.
- Gelco stainless steel flexible liners in the 316Ti alloy line handle creosote buildup differently than 304-grade competitors. The titanium-stabilized surface resists acid corrosion but can mask thin creosote layers that a quick brush misses. We use polypropylene brushes sized to Gelco’s inner diameters, then verify clearance with a camera before we call the job done.
- Gelco chase covers in the standard galvanized line installed on Severna Park townhomes from the 1990s often show rust-through at the corners where condensation pools. A chase cover is not a chimney cap; it is the roof of your chase, and when it fails, water runs straight down the flue. We document the rust pattern with photos, replace with a Gelco-compatible stainless cover or a Copperfield upgrade, and seal the counter-flashing.
- Gelco wind-directional chimney caps on homes near the Magothy River seize in the “wrong” position after seasons of disuse. The wind vane is supposed to rotate open with draft and closed against downdraft, but creosote glazing at the pivot bearing locks it. We disassemble the cap, ultrasonic-clean the bearing assembly, and re-lubricate with high-temp graphite so the mechanism moves freely through another Severna Park winter.
Our Gelco Chimney Cleaning & Sweep Process
- 1
You call, we answer. A live person at Hearthstone Chimney Co. picks up, day or night. We ask what you are burning, how often, and whether you have noticed draft problems, odors, or visible debris. If you know you have Gelco hardware, tell us the model if it is on any paperwork.
- 2
We show up when we say. Our technician arrives in a marked van, uniformed and background-checked, with Gelco-compatible brushes, rods, and camera gear already loaded. No callbacks for parts.
- 3
Inspect before we touch. We start with a Level 1 visual inspection or a Level 2 camera inspection if the system has changed hands, suffered a chimney fire, or shows suspected hidden damage. You see the photos on our tablet; we explain what we found in plain English.
- 4
Clean with the right tools for Gelco. Creosote removal on a Gelco 316Ti liner gets polypropylene brushes, not wire that can score the surface. Soot removal from a Gelco pre-fab firebox uses vacuum attachments that fit the narrower clearance zones. We protect your floors and furniture; we leave nothing worse than we found it.
- 5
Test and document. We run a draft test, check damper operation, and verify cap integrity. You get a written report with photos, our verdict on whether the system is safe to use, and any recommendations with upfront pricing.

Backed by the 90-Day Done Right Promise. If something is not right, we make it right. In writing. No arguing.
What Gelco Chimney Cleaning & Sweep Costs in Severna Park
| Service | Typical Range | What Affects Price |
|---|---|---|
| Level 1 sweep and inspection (Gelco system) | $180-$280 | Flue height, creosote thickness, accessibility |
| Level 2 camera inspection (Gelco system) | $280-$420 | Number of flues, roof pitch, chase height |
| Gelco cap removal, clean, and reinstall | $150-$260 | Corrosion severity, fastener condition |
| Gelco top-sealing damper cable replacement | $220-$340 | OEM vs. aftermarket cable, thimble modification |
| Gelco chase cover replacement | $680-$1,200 | Size, stainless vs. copper, flashing complexity |
Height matters in Severna Park. A two-story colonial off Benfield Road with a steep roof takes longer and more safety rigging than a rancher near Kinder Farm Park. Creosote density matters too; a cord of unseasoned oak produces a different cleaning job than gas soot. We give you the exact number before we start. Estimates are free. Call (443) 464-2560.

FAQs
No. Routine chimney sweeping by a qualified professional does not void Gelco’s product warranties. We document our work with photos and a written report, which actually supports any future warranty claim you might need to file. Keep your inspection records with your home files. If you have questions about a specific Gelco warranty term, call us at (443) 464-2560 and we will review it with you.
Yes, for most lines. Gelco maintained consistent sizing across their pre-set damper series and standard mesh caps for years, and we stock common replacement cables, springs, and hardware. For discontinued models, we source quality aftermarket equivalents from Famco or Copperfield that fit without modification. We will tell you before we order anything.
The camera inspection tells the story. If we find cracked flue tiles, rusted liner segments, or a deteriorating chase cover, we show you the photo and explain whether the fix is urgent or can wait a season. If the chimney is not safe to use, we will say so. If it is, we will say that too. No guesswork, no scare tactics.
The National Fire Protection Association recommends annual inspection; sweeping frequency depends on use. A Severna Park home burning two cords of seasoned hardwood per winter typically needs a sweep every year. Gas fireplaces need less frequent cleaning but still need inspection for debris, animal nests, and moisture damage from our humid summers and freeze-thaw winters.
Creosote accumulates. It is combustible. A chimney fire can crack your flue liner, damage the chimney structure, and send carbon monoxide into living spaces. Skipping sweeps also lets minor Gelco hardware issues, like a stiff damper cable or corroding cap fasteners, become expensive replacements. The $180-$280 you spend on a sweep is the cheapest insurance policy your chimney has. Call (443) 464-2560 for a free estimate.
