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.

AfterDuraFlex Chimney Cleaning & Sweep in West Hartford: What to Know First
As an independent DuraFlex service provider, we clean and sweep DuraFlex chimney liners, caps, and venting systems across West Hartford with Level-1 and Level-2 inspections, creosote removal, and full fireplace cleaning. Most DuraFlex jobs are completed in a single visit, and we quote the full price before we start - no surprises on the bill. Russell Haines and our crew have been working on these systems in West Hartford for the better part of two decades, including plenty of older colonials along Farmington Avenue that haven’t had a proper cleaning since the Carter administration. If you own a DuraFlex liner or venting product and want it swept by people who know the difference between a DuraFlex SS and a DuraFlex Pro, call us at (860) 743-1516. Estimates are free.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SS flexible liners develop creosote buildup at the corrugation valleys. The 316Ti stainless corrugations that make this liner flexible also create low spots where creosote cakes hard. In West Hartford, where homeowners burn seasoned hardwood from local cordwood suppliers, we’ve found these valleys can pack solid in as little as two seasons. We use rotary polypropylene whips sized to the liner diameter, not generic brushes that skip the valleys.
- DuraFlex Pro aluminum liners corrode at the termination cap when paired with oversized appliances. The Pro series is rated for gas and oil, but we’ve pulled failed Pro liners in Elmwood and Charter Oak where a previous installer matched a 4-inch liner to a 5-inch appliance collar. The acidic condensate pools at the cap and eats the aluminum from the top down. We replace with OEM DuraFlex Pro or, when the appliance allows, upgrade to a 316Ti SS liner that handles the duty cycle.
- DuraFlex DW double-wall factory-built sections separate at the twist-lock joints after thermal cycling. These joints are gasket-sealed, but twenty years of Connecticut freeze-thaw opens gaps that leak flue gases into the chase. During a Level-2 inspection, we smoke-test every joint and reseal with DuraFlex-compatible high-temp sealant or replace the section if the gasket channel is warped.
- DuraFlex relining tees clog at the snout connection to the appliance. The tee snout is where soot and debris collect first, especially in West Hartford’s older homes with basement furnaces that run long horizontal connector pipes. We disassemble and hand-clean the snout, then camera-inspect to confirm the main liner run is clear - no point sweeping the chimney and leaving a dam at the base.
- DuraFlex termination caps lose their spark arrestor mesh to corrosion or animal damage. A missing mesh invites birds, squirrels, and the leaf debris that West Hartford’s mature oak canopy drops in October. We stock DuraFlex-compatible caps from Olympia Chimney and Famco, or fabricate a copper cap if the chase top calls for it. Every cap gets secured with stainless screws, not the pop-rivets that shear off in the first freeze.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask the DuraFlex model or series if you know it, the appliance type, and when you last had a sweep. We quote a range before we book.
- 2
Arrival and protection. Our technician arrives in uniform, lays drop cloths from the door to the hearth or appliance, and runs a pre-cleaning camera if a Level-2 inspection was requested.
- 3
Diagnosis and parts decision. We identify whether your DuraFlex component needs OEM replacement or if a quality aftermarket part from our stock - Olympia Chimney, Famco, or Copperfield - meets the spec. We explain the choice and show you the price difference.
- 4
The sweep and any repair. We sweep to NFPA 211 standards, remove creosote and soot, and complete any agreed repair. Russell’s crew carries the full DuraFlex fitting inventory on the truck, so most jobs don’t need a return trip.
- 5
Post-job testing and documentation. We run a smoke test or final camera pass, then show you the photos. You get a written condition report and our 90-Day Done Right Promise - in writing, no arguing.
- 6
Cleanup and close. We vacuum, roll the cloths, and leave the work area cleaner than we found it. The invoice matches the estimate.
What DuraFlex Chimney Cleaning & Sweep Costs in West Hartford
DuraFlex chimney cleaning and sweep in West Hartford typically runs $289-$389 for a standard Level-1 sweep with basic creosote removal. A Level-2 inspection with full camera documentation adds $150-$225. Repairs involving DuraFlex parts - a replacement tee, cap, or liner section - range from $180-$650 depending on diameter and whether we use OEM DuraFlex or a compatible professional-grade aftermarket part.
What moves the price: liner diameter (5.5-inch and 6-inch are common; 8-inch requires larger tools), accessibility (steep roof pitches in West Hartford’s West Hill neighborhood add time), and the hardness of creosote buildup (Stage 3 glazed creosote needs chemical pretreatment and a second pass). We quote upfront. The number on the estimate is the number on the invoice. Call (860) 743-1516 for an exact quote - estimates are free.
Why West Hartford Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been sweeping chimneys in West Hartford for over 42 years, and we’ve learned that doing it right the first time, or planning on doing it twice, saves everyone time and trouble. Our 90-Day Done Right Promise means if it’s not right, we come back - in writing, no arguing. Russell Haines trains every technician to read a DuraFlex liner the way a mechanic reads an engine: the pattern of the creosote tells you how the appliance is running, and the condition of the cap tells you how long it’s been neglected.
We don’t just work on DuraFlex. We also service HeatShield and Gelco systems, so when a West Hartford chimney needs a repair that crosses brands, we don’t hand you off. A live person answers the phone every hour of every day. Our techs are background-checked, uniformed, and carry the parts to finish most jobs in one visit. That’s the Keystone Standard.
FAQs
No - professional chimney cleaning by a qualified sweep does not void your DuraFlex warranty, provided the work follows NFPA 211 standards and no liner damage is caused by improper tools. Using a brush that’s too large for your liner diameter, or a steel whip on an aluminum Pro liner, can create scratches that the manufacturer may flag. We size our tools to your specific DuraFlex series and document the condition before and after. Call (860) 743-1516 if you want us to review your warranty terms before booking.
A standard DuraFlex cleaning and Level-1 inspection takes 60 to 90 minutes for a straightforward installation with good access. A Level-2 inspection with camera documentation adds 30 to 45 minutes. Jobs involving DuraFlex tee disassembly or cap replacement in a tall West Hartford colonial may run two hours. We book enough time to finish without rushing, and we don’t leave until the smoke test passes. Call for availability - (860) 743-1516.
We stock both. OEM DuraFlex parts are available for SS and Pro series liners and fittings, and we use them when the warranty is active or when the job spec demands it. For out-of-warranty repairs, we often recommend compatible professional-grade aftermarket parts from Olympia Chimney, Famco, or Copperfield - same or better material spec, shorter lead time, and lower cost. We explain the trade-off and let you decide. Estimates are free - call (860) 743-1516.
You’ll know after our Level-2 camera inspection. A liner that needs only cleaning shows smooth walls, intact corrugations, and no holes or thinning at the joints. A liner that needs repair shows pitting, separated seams, or corrosion at the termination - and we’ll show you the photos so you can see it yourself. We don’t recommend work that can safely wait, and we don’t delay work that puts your house at risk. Call (860) 743-1516 to schedule the inspection.
NFPA 211 recommends annual inspection and cleaning as needed. For West Hartford homeowners who burn wood as a primary heat source, that usually means a sweep every year - our cold snaps in January and February push appliances hard, and the freeze-thaw cycles stress metal liners more than milder climates. Gas and oil DuraFlex systems can often go two years between sweeps if the appliance is tuned and the cap is intact. We’ll tell you honestly what your system needs after we look inside. Call (860) 743-1516 for a free estimate.
