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 Cleaning & Sweep in Lansdale: What to Know First
We provide independent Gelco chimney cleaning and sweep in Lansdale, typically scheduling within a week during peak season and within a few days in the off months. A standard Gelco sweep and Level 1 inspection runs $185-$275; a Level 2 camera inspection with full photo documentation runs $325-$450. We put the price in writing before anyone touches your chimney, and we don’t start work until you sign it.
This page is for Lansdale homeowners who heat with a Gelco-equipped fireplace, insert, or stove and want to know what service actually costs, what the camera will find, and whether their warranty stays intact. We are not affiliated with or authorized by Gelco. We are an independent Gelco service provider with no ties to the manufacturer. If you own a Gelco liner, cap, or damper and need it swept, inspected, or diagnosed, call (267) 327-4785. Estimates are free.
How Gelco Products Fail - and How We Fix Them
- Gelco stainless liners (Model 316Ti series) develop creosote adhesion at the flex joints. The corrugations trap Class II and III creosote more aggressively than smooth-wall competitors, especially in Lansdale’s freeze-thaw cycles where incomplete burns are common. We rotary-clean with poly or steel whips sized to the exact liner diameter, then camera-verify every joint before we sign off.
- Gelco top-sealing dampers (Pre-2018 cast-aluminum frames) warp under thermal cycling. The frame distorts just enough to break the seal, letting rain into the flue and accelerating creosote hardening. We measure the frame distortion with feeler gauges. If it’s within spec, we reseat and reseal; if not, we source a replacement through our Haven buying network and show you the old part before we quote the new one.
- Gelco chimney caps with spark arrestor mesh clog with cottonwood and maple seed debris common to Montgomery County. Restricted airflow causes smoky fires and incomplete combustion, which deposits more creosote. We remove the cap, clean the mesh with a wire brush and compressed air, and check the underlying flue opening for obstruction. If the mesh is corroded through, we replace with Gelco OEM or a compatible Famco cap, your choice, priced both ways.
- Gelco Heat-Fab black stovepipe connections loosen at the telescoping joint after 5-8 seasons of Lansdale heating. The joint slips, creating a gap that leaks smoke and draws room air, cooling the flue and worsening creosote buildup. We disassemble, inspect for metal fatigue, and reseat with fresh stove cement. We don’t guess at the seal - we light a smoke pellet and watch for leakage at the joint.
- Gelco UL1777 liner systems in older Lansdale colonials near the Merrick Road corridor often have inadequate chimney height for modern draft requirements. The liner works fine, but the masonry shell doesn’t extend high enough above the ridge. We document actual draft pressure in Pascals, compare it to Gelco’s spec, and if the liner is sound but the draft is weak, we quote a height extension or a draft-inducer install - never a full liner replacement you don’t need.
Our Gelco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers. We ask the appliance type, fuel, last sweep date, and any symptoms. We quote a range right then, narrow it when we see the setup.
- 2
Arrival and setup. Your tech texts when en route, arrives in uniform, lays drop cloths from the truck to the hearth. License number visible on request.
- 3
Level 1 or Level 2 inspection per NFPA 211. We decide based on what we find, not what you prepaid for. Level 2 means the camera goes down the flue, every foot recorded, with timestamps. Clause 4 of the Haven Standard requires this photo record on every job - we’ve done it since 2009.
- 4
Cleaning with brand-appropriate tools. Gelco liners get whips and brushes matched to diameter and material. We don’t use a one-size-fits-all head on a corrugated stainless liner - that’s how you score the wall and void any remaining warranty.
- 5
Written findings, written price, written scope. Before we touch a wrench, you get a single page: what we found, what it costs, what the warranty covers. Sign it or don’t. No pressure, no surprise.
- 6
Test burn and documentation. We run the appliance, verify draft, and upload your photo record to our archive. You get a copy by email. The 365-Day Done Right Promise applies from this moment.

| Service | Price Range | What Affects It |
|---|---|---|
| Level 1 sweep and inspection | $185-$275 | Appliance accessibility, single vs. multiple flues |

| Gelco cap cleaning or reseal | $95-$175 | Height of chimney, condition of fasteners |
| Gelco damper adjustment or reseat | $125-$225 | Frame condition, parts needed |

What moves the price: height of the chimney, number of bends in the flue, how long since the last cleaning, and whether we find damage that needs documenting for insurance. We don’t upsell. If it’s clean and sound, we say so, charge the base rate, and schedule next year.

Why Lansdale Homeowners Call Level Two Chimney Lansdale for Gelco Work
We’ve swept and inspected more than 38,000 chimneys since 2009, and a healthy share of them were Gelco systems in Montgomery County homes. Corrine Halstead’s crew knows the difference between a Gelco 316Ti flex liner and a smooth-wall competitor, and we stock the fittings and caps that Gelco owners actually need - not generic substitutes that sort of fit.
Every job is backed by the 365-Day Done Right Promise. Every price is written before work starts. Every visit includes a documented photo record under Haven Standard Clause 4. If you bring us a competitor’s written estimate, we’ll give you a free second opinion - no charge to look, no obligation to book.
We also carry DuraFlex and HeatShield materials for jobs where Gelco OEM isn’t the right call, and we source through Haven’s buying network specifically to keep customer prices honest. The camera doesn’t guess. Neither do we.
FAQs
No. Gelco’s warranty covers manufacturing defects, not who sweeps the chimney. The warranty requires that installation and service follow NFPA 211 standards, which is exactly what we document on every Level 2 inspection. Keep your written report and photo record - that’s your proof of proper maintenance if you ever file a claim. Call (267) 327-4785 if you need a copy of our documentation standards.
We source Gelco parts through our Haven buying network, along with DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials. For common items - caps, dampers, liner sections - we typically have them within 48 hours. For discontinued Gelco series, we’ll tell you honestly and quote a compatible alternative with the price difference shown both ways.
The camera decides. We lower it slowly, record every foot, and stop at any distortion, seam separation, or corrosion pitting. A dirty liner shows uniform creosote; a damaged liner shows the metal underneath, or gaps, or light through the wall. We show you both on screen, explain the difference, and write up exactly what we saw. No repair is recommended without photo evidence you can see for yourself.
NFPA 211 says annually for wood-burning systems, and we agree - especially given Lansdale’s hardwood mix and the creosote adhesion tendency of Gelco’s corrugated liners. Gas systems can often go two years between inspections, but we still check annually for condensation damage and debris. Call (267) 327-4785 to set a recurring date that matches your burning schedule.
Class I creosote becomes Class III glaze, which is harder to remove, more expensive to treat, and far more flammable. A glazed Gelco liner also traps moisture against the stainless surface, accelerating corrosion at the flex joints. In Lansdale’s climate, we’ve seen liners that could have lasted 20 years fail in 12 because the owner waited too long between sweeps. The camera shows the progression clearly - schedule before you see smoke backing up into the room.
