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.

DuraFlex Chimney Cleaning & Sweep in Gloucester and liner service typically runs $180-$340 for a standard sweep and inspection, with liner repairs or replacements quoted after a Level 2 camera inspection. What makes our DuraFlex work here different is the coal-flue mismatch: Gloucester’s pre-WWI brick row homes were built with wide flues for coal burning, and modern gas appliances need precisely sized DuraFlex liners to draft safely. We keep DuraFlex 316L and Pro liner sections, top plates, and insulation blankets stocked for Gloucester’s specific conditions. Call (856) 543-2929 for a free estimate.
Why Gloucester Residents Choose Us for DuraFlex Service
We’ve been working on chimneys in Gloucester since the mid-1980s, and Russell Haines, our owner, learned the trade at Los Angeles Trade-Technical College before spending twenty years on East Coast flues. That background matters here. Gloucester City’s housing stock isn’t like Cherry Hill’s post-war colonials or the newer builds out in Winslow. These are dense, late-1800s brick row homes with shared walls, original masonry stacks, and flues that were sized for coal. You need someone who recognizes what they’re looking at before they touch anything.
Our crew carries DuraFlex sales & service components on every truck: 316L and 304L flexible liners, Pro smooth-wall sections, insulation blanket kits, and OEM top plates and fittings. We’re an independent chimney company, not authorized or sponsored by DuraFlex, which means we tell you straight when a DuraFlex liner is the right fix and when repointing or another approach makes more sense. No brand loyalty that overrides your interests.
Every inspection ends with photos you can see and a plain-English verdict. If the flue is fine, we say so. If it’s not, we show you exactly why. The 90-Day Done Right Promise covers everything in writing. No arguing. Calls are answered by a live person 24 hours a day, and our background-checked, uniformed technicians complete most jobs in a single visit.
Common DuraFlex Chimney Cleaning Problems We Solve in Gloucester
- Kinked or sagging liners from offset flue tiles. In Gloucester’s oldest waterfront blocks, the soft, flood-saturated soil causes subtle foundation settlement that shears original terracotta flue tiles over decades. A DuraFlex liner slid down a straight chase works fine; one forced past two offset tiles kinks, restricts draft, and can backdraft CO into the house. We find this during Level 2 inspections and re-engineer the flue path rather than force a liner where it doesn’t belong.
- River-moisture corrosion of top plates and connectors. Gloucester sits directly on the Delaware River, and the persistent fog, tidal flooding, and freeze-thaw cycling accelerate mortar joint erosion. Water weeps behind the DuraFlex liner and rusts appliance connectors and top plates from the outside in. Cleaning alone won’t fix this; we flag it during inspection and waterproof the crown before the liner work fails.
- Acidic condensate pitting on oversized flues. Pre-WWI coal flues are dramatically oversized for modern gas appliances. Flue gases cool before exiting, condensing into acidic drips that pit the DuraFlex stainless surface over time. We specify the correct liner diameter and insulation blanket to keep gases hot and moving, not pooling against the metal.
- Loose top plates from freeze-thaw spalling. When the chimney crown spalls in Gloucester’s wet winters, the DuraFlex top plate loses its anchor. Rain and river fog pour straight into the liner. We clean, inspect, and reseat or replace the plate, then waterproof the crown to stop the cycle.
- Shared-wall chimney deterioration affecting multiple units. Gloucester’s row home construction means one failing chimney stack can compromise adjacent properties. We document what we find and explain which repairs are urgent, which can wait, and what the neighbor’s stack means for yours.
DuraFlex Service in Gloucester: What Local Conditions Mean for Your Equipment
In Gloucester City’s oldest waterfront blocks, the soft, flood-saturated soil beneath the row homes causes subtle foundation settlement that shears original terracotta flue tiles over decades, so a DuraFlex liner installation here often requires re-engineering the flue path rather than simply sliding a new liner down an intact chimney. This is not theoretical. We were called to a brick row home on King Street where the homeowner’s gas furnace had been short-cycling and the CO detector kept chirping - the original coal flue was so oversized that the DuraFlex liner for the water heater had kinked where two offset terracotta tiles pinched the chase. After a Level 2 inspection we pulled the damaged section, reamed the offset tiles, and installed a new DuraFlex 316L liner with a proper top plate and insulation blanket as part of our Chimney Repair in Gloucester. Draft restored, CO readings normal, and we waterproofed the crown before we left because the mortar joints were already spalling from river moisture.
The chimney either draws the way it should, or it does not - and we will not leave until we know which.
DuraFlex Models & Products We Service in Gloucester
We work with the full DuraFlex flexible stainless liner line and keep the most common sizes on our Gloucester-area trucks for same-visit completion.
- DuraFlex 316L stainless steel flexible liner - our standard recommendation for wood and gas appliances in Gloucester’s acidic condensate conditions; the molybdenum content resists the pitting we see in oversize, moisture-prone flues.
- DuraFlex 304L stainless steel flexible liner - budget option for dedicated wood-burning installations where condensate exposure is lower.
- DuraFlex Pro stainless liner with smooth inner wall - improved draft performance for marginal chimney heights or appliances at the edge of their rated capacity.
- DuraFlex insulation blanket kits and component fittings - critical for maintaining flue gas temperature in Gloucester’s wide coal-era chimneys; we stock these because underspecified insulation is a leading cause of premature liner failure in this market.
For the liner itself, we recommend staying with DuraFlex-spec components. The wall thickness and alloy matter for the conditions here. We’ll quote aftermarket caps and generic connectors when they fit properly, but we won’t substitute on the liner and tell you it’s the same thing.

FAQs - DuraFlex Chimney Cleaning in Gloucester
Your chimney was built for coal, not gas. The flue is too wide, so flue gases cool, condense, and can backdraft into your living space. A properly sized DuraFlex liner creates the correct draft path for your modern appliance. Call (856) 543-2929 for a free inspection to see if your flue is oversized.
A DuraFlex liner bypasses damaged tiles, but only if the flue path can be re-engineered to accept it. In Gloucester’s oldest blocks, offset tiles from foundation settlement may need reaming before the liner goes in. We determine this during a Level 2 camera inspection, not by guessing.
Delaware River fog, tidal flooding, and freeze-thaw cycling erode mortar joints and let water weep behind the liner. This rusts top plates and connectors from the outside, even when the stainless liner itself looks fine. We waterproof crowns and recommend inspections every 12 months in Gloucester’s conditions.
We stock genuine DuraFlex liner sections, top plates, and insulation blankets because the alloy and wall thickness matter for Gloucester’s acidic condensate. We’ll use aftermarket caps and connectors when they fit properly, but we won’t substitute on the liner itself and claim it’s equivalent.
Once per year for gas appliances, and after every cord of wood for solid fuel. Given Gloucester’s river-moisture acceleration of mortar and crown deterioration, we recommend a Level 2 inspection every two years even if the liner is cleaning up fine. Call (856) 543-2929 to schedule - estimates are free.
