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 Bangor: What to Know First
We provide independent Gelco chimney cleaning and sweep service in Bangor, typically scheduling within a few days and completing most jobs in a single visit. A standard Gelco annual sweep with Level 1 inspection runs $175-$265, and we agree on the exact price before we start. We are not affiliated with or authorized by Gelco - we are an independent Gelco service provider - which means we work for the homeowner, not the manufacturer, and we will tell you plainly when a repair can wait and when it cannot.
This page is for Bangor homeowners who heat with a Gelco-equipped fireplace, insert, or stove and need the flue cleaned, inspected, or cleared of creosote buildup before the burning season. If you smell smoke in the room, see black buildup above the firebox, or it has been more than a year since your last sweep, call (610) 609-7634. A live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco Pre-Fab Fireplace Units (Model 36/42 Series): The factory-built firebox panels in these units develop hairline cracks after 15-20 years of Bangor freeze-thaw cycling, especially in homes near the Slate Belt where temperature swings are sharper. During sweep and inspection, we photograph every panel and distinguish between cosmetic crazing and true breach - a difference that saves homeowners from unnecessary $2,000+ rebuild quotes.
- Gelco Stainless Steel Chimney Liners (ProFlex and UltraPro): The corrugated flex sections can trap creosote in the valleys, particularly when homeowners burn unseasoned hardwood common in Northampton County. Our rotary cleaning system matches the liner diameter exactly - no oversized brushes that scar the stainless - and we document wall thickness with a borescope to catch the thinning that precedes a liner failure.
- Gelco Chimney Caps (Standard and Wind-Resistant Lines): The mesh spark arrestor on standard caps clogs with Bangor’s cottonwood seed and maple helicopter debris every May and June, restricting draft and forcing smoke backward. During sweep service, we remove, clean, and reset the cap, or recommend the Wind-Resistant upgrade if your cap sits in a channel that accelerates debris accumulation.
- Gelco Cast Iron Stove Components (Defender and Summit Series): The throat plate and baffle boards above the firebox collect glazed creosote that standard brushing will not touch. We use a controlled mechanical de-glazing process - never chemical sprays that void the stove’s warranty - and reassemble to factory clearances so the stove drafts correctly.
- Gelco Masonry Chimney Crowns (Poured and Precast): The poured crowns on Bangor’s 1920s and 1930s homes crack where the Gelco liner passes through, letting water follow the flue and damage the smoke chamber. Our Level 2 inspection catches this before the sweep begins, and we repair with HeatShield CrownCoat or full repour depending on crack width - documented with photos you can see.
Our Gelco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, notes your Gelco model if you know it, and books a window. We send a confirmation text with Russell’s photo and technician name.
- 2
Arrival and protection. Our technician lays floor and furniture protection, then runs a Level 1 or Level 2 inspection depending on what we find - Gelco pre-fab units almost always get the camera.
- 3
Diagnosis and plain-English verdict. You see the photos on the tablet. We explain creosote grade (Stage 1, 2, or 3), any part wear, and whether the fix is sweep-only or needs parts. No surprises on the bill.
- 4
Sweep and component service. Rotary or manual brushing matched to your flue type. Gelco liners get polymer brushes, not steel. Caps come off, are cleaned, and resealed. Firebox panels are photographed.
- 5
Testing and documentation. We run a draft test and smoke-puffer check. You get a written report with photos, the 90-Day Done Right Promise in writing, and our recommendation for next service.
- 6
Cleanup and close. HEPA vacuum, drop-cloth removal, and the technician walks you through every photo. Payment is due only when you are satisfied the flue is clean and safe.

We agree on the exact number before any work starts. Call (610) 609-7634 for a free estimate - we will ask the right questions about your Gelco unit so the quote is accurate when we arrive.
Why Bangor Homeowners Call Hearthstone Chimney Co. for Gelco Work
We have been sweeping chimneys in Bangor and the Slate Belt for over 42 years. Russell Haines learned this trade at Los Angeles Trade-Technical College, and he has spent the better part of two decades working on the older homes near the Bangor Borough Historic District - the kind of jobs that test every skill a sweep claims to have. That worn inspection mirror on his truck dashboard has seen more than a thousand flues, and it goes on every Gelco job.
Our technicians are background-checked, uniformed, and trained on Gelco’s specific clearances and assembly points. We carry DuraFlex and HeatShield materials for repairs that Gelco does not make, and we document everything with photos and a plain-English verdict. The 90-Day Done Right Promise is in writing, with no arguing - if it is not right, we come back. A clean flue does not need a sales pitch.
FAQs
No. Routine chimney cleaning and inspection by a qualified professional does not void a Gelco product warranty, provided the work is documented and no unauthorized modifications are made. We note every step in our written report, and we use warranty-safe practices - no chemical de-glazers on cast components, no oversized brushes on stainless liners. If you have a specific warranty concern, bring your paperwork and we will review it before we start. Call (610) 609-7634 with questions.
Once per year for wood-burning units, per NFPA 211. In Bangor, where homeowners often burn oak and hickory from local woodlots, we see heavier creosote deposits than in gas-only regions - so if you burn more than three cords per season, consider a mid-season inspection. Gelco gas inserts need annual inspection too, though the cleaning is lighter. Call (610) 609-7634 to schedule around your burning season.
We source OEM Gelco parts through our supply network, and we also stock quality aftermarket alternatives from Famco and Copperfield when the OEM part is back-ordered or discontinued. We will show you both options with pricing and let you decide - no pressure either way. Most Gelco sweep jobs need no parts at all. Call (610) 609-7634 for a free estimate.
It depends. If the flue is clogged with creosote or the damper is stuck with soot, a thorough sweep usually fixes it. If the smoke chamber is improperly sized for the firebox, or the chimney is too short for the roofline, that is a design issue we will document with our Level 2 camera and explain in plain English. We do not recommend masonry work or liner replacement without photo evidence you can see yourself. Call (610) 609-7634 and we will diagnose it properly.
We typically schedule within a few days, and most Gelco sweeps take 60-90 minutes on site. During peak pre-season (September through November), booking a week ahead is wise. We do not overbook - we will be there when we say. Call (610) 609-7634 to reserve your slot.
