Why Orlando Homeowners Choose DuraFlex Chimney Cleaning
Duraflex in Orlando chimney cleaning requires specialized knowledge of flexible aluminum liner systems and the particular stresses Florida’s climate places on them. We provide independent DuraFlex service throughout Orlando, using OEM-compatible parts and warranty-safe methods developed over hundreds of Central Florida relining jobs. Our crew understands that DuraFlex liners here fail differently than they do up north - moisture damage and wildlife intrusion outrank creosote as the primary threats.
We are not affiliated with or authorized by DuraFlex. We are an independent service provider who chooses to work on their products because we know them well and stock the parts Orlando homeowners need. Roy Dempsey, our owner, grew up in College Park watching his grandfather tend an old bungalow fireplace, and he built Hearthstone Chimney Co. on the principle that a straight answer beats a slick pitch every time. A clean chimney is not a luxury - it is just the job done right. Call (877) 565-7563 when you’re ready.
Why Trust Hearthstone Chimney Co. of Orlando for Your DuraFlex Chimney Cleaning?
Our technicians complete DuraFlex-specific training on proper sizing, sealing, and UL listing compliance before they touch a liner in the field. We have worked on DuraFlex AL20, AL28, AL30, and DuraFlex Pro systems across Orlando’s sprawling suburban neighborhoods, from Winter Park ranch homes to newer builds near Lake Nona. That repetition matters. We have seen what happens when an installer skips backfill support at an offset bend, or when a homeowner in Dr. Phillips assumes their barely-used fireplace doesn’t need inspection because there’s no soot.
Roy Dempsey spent nearly twenty years on Central Florida chimneys before founding Hearthstone in 1984. He graduated from Seminole State College’s building construction program in Sanford, and he still reviews photos from every Level-2 camera inspection we perform. His youngest daughter calls him the chimney guy at school. He considers that fair. We document every DuraFlex job with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise covers the work in writing, no arguing. Background-checked, uniformed technicians. Most jobs done in one visit. The number on the estimate is the number on the invoice.
Common DuraFlex Chimney Cleaning Problems We Fix in Orlando
- Liner crushing at offset bends. The DuraFlex AL28 and AL30 are built to navigate masonry offsets, but they crush when installers skip proper backfill support with vermiculite or similar insulation. In Orlando, we find this most often in 1980s-era homes in Altamonte Springs and Casselberry, where original installers cut corners during the building boom. A crushed liner restricts draft and can trap carbon monoxide. We diagnose this with our camera, then either reform the liner or recommend full replacement if the damage has compromised the UL listing.
- Corrosion at the top six inches. DuraFlex AL20 liners suffer accelerated corrosion where moisture collects from rain and combustion condensation. Orlando’s year-round humidity above 70 percent makes this worse than the manufacturer expects. The top section sits below the cap, exposed to every afternoon thunderstorm from June through September. We inspect this zone with a zoom camera and replace the damaged section with genuine DuraFlex OEM tube when possible, or recommend full reline if the corrosion has propagated downward.
- Sagging or separation at the anchor plate connection. The anchor plate secures the DuraFlex liner to the appliance or thimble. Heat cycling and Florida’s thermal expansion patterns loosen the connection over time. We find this on gas conversions where the original installer used a generic adapter instead of the DuraFlex-specified plate. Our crew carries OEM anchor plates and fasteners for the AL20 through AL30 series, and we torque to spec, not guesswork.
- Creosote bridging in tight-fit installs. DuraFlex Pro liners installed with minimal clearance can develop hard creosote bridges that standard brushes won’t clear. We encountered this in a Dr. Phillips home - a heavy Stage-3 plug in a DuraFlex AL28 that hadn’t been swept in three seasons. After power sweeping and installing a new DuraFlex multi-flue cap with spark arrestor, draft improved from 0.02″ to 0.06″ and the carbon monoxide reading dropped to zero. That is the difference proper cleaning and capping makes.
- Wildlife intrusion and moisture damage. Orlando’s chimney swifts, federally protected under the Migratory Bird Treaty Act, roost in uncapped DuraFlex flues during migration. Once eggs are present, the chimney is legally off-limits until they vacate. We install DuraFlex-compatible caps with proper spark arrestor mesh before nesting season begins, and we inspect for the mold growth that thrives in humid, unused flues - a far more common finding here than creosote.
DuraFlex Parts & Our Repair-vs-Replace Approach
We stock genuine DuraFlex OEM parts for the AL20, AL28, AL30, and DuraFlex Pro series at our Orlando warehouse. That means anchor plates, top connectors, flexible tube sections, and proper termination caps - not hardware-store substitutes that void your warranty. We also carry quality aftermarket components when they meet or exceed OEM spec and the manufacturer allows their use.
Our rule on Chimney Repair services versus replace is simple: we recommend replacement only when the liner is crushed, corroded beyond section repair, or exceeds twenty years of service. Orlando’s humidity can age a DuraFlex liner faster than the manufacturer anticipates, but we do not push a full reline for upselling. If a section replacement and proper cap installation will solve the problem, that is what we propose. Done right - and we stand behind it. Call (877) 565-7563 for an honest assessment.
Our DuraFlex Service Process - Step by Step
- 1
Diagnosis with Level-2 camera inspection. We run a high-resolution camera through your DuraFlex liner, documenting crushing, corrosion, creosote buildup, or moisture damage. You see the photos. We explain what they mean in plain English. No jargon, no scare tactics.
- 2
Repair or install with OEM-compatible parts. We size DuraFlex components to your appliance and flue dimensions, using the correct anchor plate and termination for your model series. For gas fireplace conversions, we verify UL listing compliance and local code alignment.
- 3
Testing for draft and spillage. We measure draft pressure with a manometer and check for carbon monoxide spillage at the appliance and living space. The numbers either pass or they don’t. We show you both.
- 4
Documentation and warranty. You receive photos, the inspection report, and our 90-Day Done Right Promise in writing. If something is not right, we make it right. No paperwork to file, no argument to win.

Light dents can sometimes be cleaned if they do not restrict draft or compromise the UL listing. A crushed liner cannot be safely cleaned and must be reformed or replaced. We determine this with a camera inspection, not guesswork.
A properly installed DuraFlex AL20 should last 15 to 20 years, but Orlando’s constant moisture exposure can shorten that by several years if the cap is missing or damaged. Annual inspection catches corrosion before it spreads. We have replaced AL20 liners in Orlando that failed at 12 years due to water intrusion, and others still sound at 22 with proper capping.
Yes, DuraFlex AL20 and AL28 liners are UL listed for gas appliance venting when properly sized and terminated. We verify local code compliance with Orange County or your municipality and ensure the anchor plate and cap match the appliance category. Improper conversion without this step is a common source of carbon monoxide spillage.
Residual odor usually means creosote has absorbed into a porous masonry surround, or there is a drafting problem unrelated to cleanliness. In Orlando, we also find that humidity activates old soot deposits, producing a musty smoke smell even in clean liners. We diagnose the actual cause rather than cleaning twice for no reason.
Our 90-Day Done Right Promise covers all DuraFlex repairs in writing. If the repair fails due to our workmanship or material defect, we return and fix it with no argument and no paperwork for you to file. We have honored this promise for over 42 years.
