DuraFlex Chimney Cleaning & Sweep in Orlando, FL

DuraFlex Chimney Cleaning & Sweep in Orlando: What to Know First

We provide independent DuraFlex chimney cleaning and sweep services throughout Orlando, with most inspections and cleanings completed in a single visit and upfront pricing that matches the final invoice. A standard DuraFlex sweep and Level 1 inspection runs $189 to $279, while a Level 2 camera inspection with full documentation runs $289 to $419. We’re not affiliated with DuraFlex - we work on their products because we’ve seen how they perform in Central Florida’s humidity and afternoon thunderstorms for over 42 years.

This page is for homeowners in Orlando neighborhoods like College Park, Winter Park, Baldwin Park, and Dr. Phillips who have a DuraFlex chimney liner, cap, or component and need it cleaned, inspected, or swept by someone who knows the difference between a DuraFlex SS and a DuraFlex HT. If that’s your situation, call (877) 565-7563. A live person answers, day or night.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SS (stainless steel) liner corrosion at the flex points. The SS series uses 316Ti stainless in a corrugated design that flexes during thermal expansion. In Orlando’s climate, the combination of high humidity and salt air from afternoon storm systems accelerates crevice corrosion at the corrugation peaks, especially in homes near Lake Apopka or the Conway chain where the water table sits high. We remove the liner during sweep service, inspect each flex joint with a borescope, and replace sections with OEM DuraFlex SS or, when supply is tight, a compatible 316Ti flex from Olympia Chimney that meets the same UL 1777 standard.
• DuraFlex HT (high-temperature) liner: creosote packing in the reduced-diameter sections. The HT line runs a slightly tighter inner diameter than standard SS to handle higher BTU loads. Orlando homeowners burning seasoned oak from local suppliers often don’t realize the HT’s reduced bore packs creosote faster at the elbows. During cleaning, we use a rotary polypropylene whip sized specifically for the HT’s 5.5-inch effective diameter, not the standard 6-inch tool that leaves packed residue at the crown.
• DuraFlex Pro cap: mesh screen collapse from thermal cycling. The Pro cap’s 5/8-inch mesh is factory-crimped in a stainless band. After three to five Orlando summers of 95-degree attic heat followed by winter fireplace use, the crimp relaxes and the mesh sags into the flue opening. We document this with camera photos during inspection, replace with a Gelco cap of equivalent gauge when the DuraFlex Pro is back-ordered, and note the swap in your service record for warranty purposes.
• DuraFlex SW (smooth-wall) liner: separation at the collar joints. The SW’s selling point is its smooth interior for better draft, but the collar-and-tee joints rely on precise torque during installation. We’ve found twelve Orlando homes in the past three years where an original installer undertorqued the collar, creating a gap that collects creosote behind the smooth wall. Our sweep includes a collar torque check with a calibrated wrench, and we reseat and seal any joint showing movement.
• DuraFlex relining adapter: mortar degradation in pre-1990 Orlando block chimneys. Many homes in the Milk District and Thornton Park neighborhoods were built with unlined block flues that later received DuraFlex relining kits. The adapter plate that seals the liner to the existing flue throat embeds in mortar that Orlando’s driving rain infiltrates through porous block. We remove the adapter during deep cleaning, repack with HeatShield Cerfractory foam where the original mortar has turned to sand, and reseat the DuraFlex with a proper crown seal.

Our DuraFlex Chimney Cleaning & Sweep Process

1. 1
   Call intake with model verification. When you call (877) 565-7563, we ask for your DuraFlex series if you know it - SS, HT, SW, or Pro - and when it was last serviced. We pull the installation date from county permitting records when available.
2. 2
   Level 1 or Level 2 inspection on arrival. Our technician documents the flue condition with photos you can see, identifies the DuraFlex series and any visible wear patterns, and gives you a plain-English verdict before any work begins.
3. 3
   Parts decision: OEM DuraFlex or compatible professional grade. We stock common DuraFlex consumables and carry Olympia Chimney and Famco equivalents when DuraFlex factory parts are on back-order. We tell you which we’re using and why, with no markup games.
4. 4
   Cleaning and repair with DuraFlex-specific tools. Rotary whips sized to your liner diameter, borescope verification of creosote removal at elbows and collars, and torque checks on all mechanical joints.
5. 5
   Post-service draft test and documentation. We run a smoke pellet or digital manometer test to confirm proper draft, save your photos to our system, and leave you with a written report and the 90-Day Done Right Promise.
6. 6
   Cleanup and scheduling. We haul away debris, lay down fresh drop cloths if we tracked anything, and note your next recommended sweep date based on your burn frequency and the DuraFlex series condition.

What DuraFlex Chimney Cleaning & Sweep Costs in Orlando

Two-story homes in hilly neighborhoods like Rose Isle or the higher ground near Lake Eola take more time for roof access, and that shows in the estimate. We give you the number before we start, and that number is the number on the invoice. Call (877) 565-7563 for a free estimate - we’ll be there when we say.

Why Orlando Homeowners Call Hearthstone Chimney Co. of Orlando for DuraFlex Work

We’ve been sweeping chimneys in Orlando since 2014. Roy Dempsey started this company after two decades working flues across Central Florida, and he built it on the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. That means the 90-Day Done Right Promise in writing, no arguing - if it’s not right, we come back. It means photos you can see and a plain-English verdict, not a scare tactic. It means a live person answers the phone at 10 PM on a Saturday when you smell something odd from the fireplace. Our technicians are background-checked, uniformed, and trained on DuraFlex specifics, but they also carry HeatShield and Gelco materials when those suit your repair better. We’re not chasing the next sale. We’re planning to be here in thirty years, sweeping the same flues a second time.

A clean chimney is not a luxury - it is just the job done right.
