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 in Wellesley, MA | Top Hat Chimney
We provide independent DuraFlex Chimney Cleaning & Sweep in Wellesley, inspection, and liner service across town, and the one thing that separates our DuraFlex work here from anywhere else is the multi-flue reality of this town’s older homes. Most Wellesley houses built before 1940 have two or three masonry chimneys, and at least one of them was never properly decommissioned. That means a DuraFlex cleaning visit in Wellesley is rarely just about creosote. It’s about figuring out what’s happening in the flues you use, and the ones you forgot you had. Call (781) 378-5846. Wendell Pike has been working these chimneys since 1999.
We’re independent. We do not work for DuraFlex, we’re not a factory-authorized shop, and nobody pays us to push their liner. We install and service DuraFlex sales & service because the product has earned its place over thousands of feet of liner we’ve run here. But we’ll also tell you when a DuraFlex liner is the wrong answer and a repair or a different approach makes more sense. That’s the job.
Why Wellesley Residents Choose Us for DuraFlex Service
Wendell learned the trade at Palomar College, got his hands dirty early, and has spent the last two decades driving out to the Wellesley service area and the surrounding towns doing work most people are glad someone else will handle. But hands-on experience in this specific town matters more than any training certificate. The older colonials near Wellesley Hills and Wellesley Farms are different from the postwar tract houses in Natick or Framingham. Different flue sizes. Different original clay liners. Different patterns of what goes wrong after gas conversion.
We spec DuraFlex 316L for relines where the original clay tile has already spalled from decades of acidic gas-condensate. That recommends us to a certain kind of homeowner. Not because we’re the only ones who can run the liner, but because we know what a correct fit looks like in Wellesley’s older flues. If the liner is sized wrong, or the top plate doesn’t seat, or the joint at the clay tile transition is sloppy, you’ll know it within a year. We’d rather take the extra hour and do it right the first time. If it does not need doing, we will tell you.
Every one of our techs is background-checked and arrives in uniform. Calls are answered by a live person around the clock, and it may well be Wendell himself picking up. You’ll get a real arrival window, and if that window slips, you’ll get a call. No call center. No national-dispatch runaround.
Common DuraFlex Chimney Cleaning Problems We Solve in Wellesley
- Corrugation pinholes from trapped water in abandoned flues. This is the big one in Wellesley. Homes with a retired furnace flue that was never correctly sealed trap moisture against the liner wall. Over a few Wellesley winters, freeze-thaw cycling pushes that trapped water through the corrugation folds. We find pinhole rust during multi-flue inspections before a chimney becomes a water feature.
- Torn or poorly seated liner seams at clay tile transitions. When a former coal chute gets converted to gas without relining, the original clay tile transition points are rarely smooth. An improperly seated DuraFlex seam at those transitions will pull apart under thermal cycling. We see it most in Wellesley homes where the conversion happened in the 1980s and 1990s, before liner standards tightened.
- Oversized 316L liners causing low draft and rapid creosote buildup. Some Wellesley fireplaces are huge by modern standards. Put a full-diameter 316L liner in an original 8×12 clay flue where the firebox is actually modest, and you get low draft. Low draft means smoldering fires. Smoldering fires mean glazed creosote faster than any brush can keep up with. Sizing matters more here than in newer construction.
- Improperly insulated liners in exterior chimneys. Wellesley’s freeze-thaw cycle is relentless. An exterior chimney with an uninsulated or under-insulated DuraFlex liner experiences temperature swings that crack the surrounding masonry. Once the masonry shifts, liner joints pull apart. Insulation is not optional on an exterior Wellesley chimney. It’s the thing that keeps the liner intact.
- Rust staining at liner joints. The quiet sign. When you see rust at the joints of a DuraFlex liner, water is finding its way in. In Wellesley, that usually means a rain cap that’s shifted, a top plate that isn’t sealed, or a crown that’s spalling. The liner gets blamed. The liner is rarely the actual problem. It’s what sits above it.
DuraFlex Service in Wellesley: What Local Conditions Mean for Your Equipment
Nowhere else in Wellesley’s immediate suburbs do we see as many homes where the ‘inactive’ furnace flue was capped with a loose brick or sheet metal instead of a proper DuraFlex closure. A piece of sheet metal leaned over a flue opening might have felt adequate in 1967. It is not adequate in a Wellesley Hills winter. That uncapped void keeps wicking cold air and moisture into basements all winter long, and homeowners end up heating against a draft they can’t see, can’t locate, and have been told for years is just “an old house thing.” It isn’t. It’s a decommissioning problem. When we clean a DuraFlex-serviced fireplace in Wellesley Hills, we routinely probe the adjacent furnace flue, because that’s where the actual moisture problem lives. A properly installed DuraFlex closure plate costs a fraction of what a season of chasing a mystery draft costs in lost heat. And the camera footage shows you, with your own eyes, what’s been hiding in that flue. The camera footage and a plain-English verdict, every time, no exceptions.
On a Wellesley Hills street of 1920s Tudors, our tech swept a fireplace flue and then probed the adjacent furnace flue that had been brick-capped for decades. Inside, the original clay tiles were spalled from gas-condensate, and the homeowner had been heating against a constant cold draft from that open flue. We pulled the loose brick, ran a camera, and later installed a correctly sized DuraFlex 316L liner with a sealed top plate and cap as part of our Wellesley Chimney Repair service. That’s what a proper decommissioning looks like. Not a brick. A system.
DuraFlex Models & Products We Service in Wellesley
We work on the full DuraFlex line: 316L for gas and oil venting, AL for high-efficiency gas, PRO for the heavier applications, and Smooth Wall where draft improvement is the goal. We stock genuine DuraFlex connectors, top plates, rain caps, and transition pieces for fast Wellesley turnaround. Mixed-system liner parts fail at the joints, and that’s where Wellesley’s moisture problems start. We don’t cobble together generic fittings to save a few dollars. The OEM-vs-aftermarket difference shows up in how long the joint holds, not in how it looks the day it’s installed.
When a DuraFlex liner is beyond salvage, we say so. A failed liner in a compromised clay flue is a replace, not a patch, recommendation. And we’ll show you the camera footage to back it up.
DuraFlex Service Pricing in Wellesley
DuraFlex chimney cleaning in Wellesley typically runs $180 to $340 depending on how many flues you have and what condition they’re in. A Level 2 inspection with camera runs $150 to $400 if we’re doing it as a standalone. If a liner reline is actually needed, you’re generally looking at $2,500 to $7,500 for a single flue in this town, and $5,000 to $9,000 for full-width replacements on larger original chimneys because of access complexity. Most single-flue gas conversion relines land between $2,500 and $5,000, materials and labor included. Those numbers reflect what we see in Wellesley specifically, where older masonry and multi-flue homes push labor costs up compared to simpler suburban jobs.
Every estimate is free, in writing, and the number you hear on the phone is the number on the invoice. We offer $40 off any repair over $200, a free second opinion on any competing written estimate, no trip charge inside the county, and 10% off always for seniors and veterans.

FAQs - DuraFlex Chimney Cleaning in Wellesley
No. You need a proper closure, not a full liner. A correctly installed DuraFlex top plate with a sealed cap and a rain guard does the job. The problem is that a loose brick or sheet metal does neither. Call (781) 378-5846 and we’ll camera the flue to confirm what’s actually needed.
Rarely, if the liner is installed correctly. The liner’s stainless wall is not the weak point. The weak points are the joints, the top plate seal, and the surrounding masonry. When Wellesley’s freeze-thaw cycle cracks the crown or shifts the brick, the liner joints take the stress. A properly insulated and correctly installed DuraFlex liner holds up. The chimney around it is what needs attention.
Rapid creosote buildup. When a liner is oversized for the firebox, you get low draft. Low draft means incomplete combustion. Incomplete combustion means creosote. If you’re brushing a DuraFlex-lined flue two or three times a season when you used to brush it once, the liner is probably too big. We can measure and tell you. Call (781) 378-5846.
Water is getting in at the top. The rust at the joints is a symptom, not a cause. Usually it’s a shifted rain cap, an unsealed top plate, or a spalling crown. The liner gets blamed because the rust shows at the joints, but the fix is on the roof, not inside the flue. We’ll camera it and show you exactly where the water is entering.
Often, yes. A fireplace flue sized for an open wood fire is usually too big for a gas insert. The gas insert needs a correctly sized liner, and in most Wellesley pre-war chimneys that means running a new DuraFlex AL or 316L liner sized for the appliance. Oversizing the liner on a gas insert gives you condensation and draft problems. Call (781) 378-5846 for a free estimate on the conversion.
