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 in Montclair, CA | San Bernardino Chimney Sweep
We provide independent DuraFlex in Claremont and across Montclair, including the 91763 ZIP code. What makes our work here different is that most Montclair chimneys are original 1950s-70s masonry fireplaces with undersized flues, so a standard cleaning isn’t just about soot, it’s about checking whether the DuraFlex liner is actually the right fit and holding up to decades of dry Inland Empire heat. Call Allen and our team at (877) 516-7159 for a free estimate. We find it and we fix it.
Why Montclair Residents Choose Us for DuraFlex Service
We’ve worked on DuraFlex liners across enough older Inland Empire homes to know that what holds up in a newer build doesn’t always survive a 1962 tract house with an original brick chimney, which is why we also offer DuraFlex service in Ontario. Allen Prescott, our owner, grew up near the Kendall Drive corridor in San Bernardino and spent years at San Bernardino Valley College studying HVAC and building systems before narrowing his focus to chimney and venting work. That background matters when a DuraFlex liner has been crammed into a flue that was never sized for modern venting requirements.
We’re an independent service provider, not a manufacturer dealer, so we follow DuraFlex’s published specs without any corporate sales agenda. When we recommend a repair, it’s because the liner needs it. When we say it can wait another season, we mean that too. Montclair homeowners keep calling us because we stock OEM-compatible parts locally and don’t need to make you wait weeks for a backordered component.

Common DuraFlex Chimney Cleaning Problems We Solve in Montclair
- Cracked or separated clay flue tiles behind the liner. Montclair summers bake old masonry, and those original clay tiles expand and crack. Moisture and creosote then work their way between the tile and the DuraFlex liner. During cleaning we check for exactly this, because it’s the most common hidden failure we see in the 1950s-70s tracts here.
- Liner joints loosened by seasonal expansion. Fireplaces in Montclair get used maybe a dozen times each winter, then sit for months. That on-off cycle means the stainless liner expands and contracts repeatedly. A separated joint causes smoke leakage and draft problems, and you’ll usually smell it before you see it.
- DuraFlex cap and top plate corrosion from wind-driven dust. The Inland Valley throws dust at your roof all summer. Wind carries fine grit that scours the cap, loosens it, and eventually lets water and birds in. We replace more caps in Montclair than nearly any other component.
- Soot and debris masking liner damage. Because creosote builds slowly here, homeowners go years between cleanings. The soot isn’t the real danger, it’s what’s hiding underneath. A camera inspection during your sweep shows us whether the liner surface is still sound or whether you’re looking at hidden pitting.
- Undersized flues from the original build. This is the Montclair-specific one. Many of these mid-century homes have flues that don’t meet current code for the fireplace size. If a previous owner had a DuraFlex liner installed without correctly sizing it, we’ll catch that during cleaning and tell you straight.
DuraFlex Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair is a small, mostly post-WWII bedroom community where the housing stock runs heavily to single-story tract homes built between the 1950s and early 1970s. Walk down any residential street off Central Avenue or Monte Vista Avenue and you’ll see the same story: original brick and masonry fireplaces that were built for aesthetics, not for modern venting demands. The flues are smaller than what current codes allow for a properly sized DuraFlex liner. That means a chimney cleaning in Montclair isn’t just a routine sweep. It’s a check on whether the liner was actually sized correctly to begin with, and whether it’s still drafting properly after decades of dry heat and sporadic winter fires. Newer neighborhoods in Chino or DuraFlex service in Upland don’t present this same problem, because their fireplaces were built to contemporary standards with larger, properly proportioned flues. In Montclair, we’re often the first ones to tell a homeowner that the liner pulling smoke properly today may be the same one a previous contractor jammed in ten years ago without checking the original flue dimensions.
A clean flue isn’t a luxury, it’s just how you keep the fire where it belongs.
DuraFlex Models & Products We Service in Montclair
We service all the DuraFlex liner lines we see in local homes: the DuraFlex Pro, DuraFlex Plus, DuraFlex SS, and the standard DuraFlex Flex. Each has its own clearance requirements and failure profile, and we know which ones tend to show up in Montclair’s older flues. When a component needs replacing, we use OEM DuraFlex parts first, because the fit and metallurgy are what the system was designed around. If a cap or non-critical part is backordered, we’ll recommend a quality aftermarket option and tell you that’s what we’re doing. No surprises. What we won’t do is patch a compromised liner. Compromised stainless can’t be restored, so if your liner is beyond safe repair, we’ll advise replacement and walk you through what that costs before any work starts. Our DuraFlex sales & service page covers the product lines in more detail if you want to read up before calling.

AfterDuraFlex Service Pricing in Montclair
Chimney cleaning with a DuraFlex liner inspection in Montclair typically runs $180 to $340, depending on what we find and how much buildup has accumulated since the last sweep. A Level 2 inspection, which includes a camera run through the liner, adds roughly $150 to $300 to the job, and it’s the best way to actually see whether your liner is still sound. Cap replacement usually falls between $200 and $500, depending on the part and the roof access. If we discover damage during cleaning that requires repair, we’ll show you the camera footage and give you a flat price before anything else happens. Nothing gets recommended without evidence you can see yourself. Call (877) 516-7159 for an exact quote. Estimates are free.

FAQs – DuraFlex Chimney Cleaning in Montclair
No. Independent companies like ours service DuraFlex liners all the time using the manufacturer’s published specifications. We’re not a DuraFlex dealer or affiliate, which means our recommendations come from what we see in your flue, not from a sales target. We use OEM parts whenever they’re available because they fit correctly, but independence means we’ll tell you when a repair is optional and when it’s genuinely urgent.
Usually yes, but the first thing we check is whether your original flue is sized for the liner. Many mid-century Montclair homes have flues that were built smaller than current code requires, which means a properly sized liner sometimes needs a different approach than a straight drop-in. We’ll assess the flue dimensions, show you the measurements, and give you a straight answer about what will actually draft safely. Call (877) 516-7159 and we’ll schedule a look.
Even with light seasonal use, we recommend an annual sweep for any DuraFlex-lined chimney in Montclair. The creosote buildup is slower here than in colder climates, but dust, wind-driven debris, and cracked crowns are constant issues. A yearly cleaning catches cap damage and liner joint separation before they become expensive repairs. If you can’t remember the last time it was done, it’s time now.
You’ll typically see water stains on the ceiling near the chimney, hear birds or scratching sounds from the flue, or find rust flakes on the hearth or roof. Wind-driven dust and debris in the Inland Valley is hard on caps, and a loose or corroded cap lets water and animals directly into your liner. A quick cap replacement during a cleaning is cheaper than repairing water damage to a liner that’s been sitting damp all winter. Call (877) 516-7159 and we’ll check it during the sweep.
Yes, we repoint and repair crowns as part of our chimney repair service, often during the same visit as a cleaning. Montclair’s dry heat and occasional hard rain cycle puts stress on masonry crowns, and a cracked crown lets water run down into the flue and eventually onto the top of your DuraFlex liner. If we see crown damage during your sweep, we’ll show you the crack on camera and give you a price to fix it before it becomes a liner problem. Our full repair capability is covered on our Montclair service area page.
