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 Mid-Wilshire, CA
We provide independent DuraFlex chimney cleaning and service across Mid-Wilshire, and the quick answer is this: most of our calls here aren’t about heavy creosote from wood heat. They’re about confirming a DuraFlex liner that was retrofitted into a 1920s or 30s Spanish Colonial or Tudor chimney is still sealed, intact, and safe to document for a tenant or a home sale. If you own one of the older duplexes along the Wilshire corridor or near the Miracle Mile fringe, call (855) 731-2852 and we’ll get your flue inspected properly.
We’re an independent service provider, not a manufacturer affiliate, so our assessment of your DuraFlex liner is based on what we actually find in your chimney, not on any obligation to sell you a new one. That matters in Mid-Wilshire, where decorative fireplaces sit unused for years and problems hide until someone finally looks.
Why Mid-Wilshire Residents Choose Us for DuraFlex Service
Ernie Pennington, our owner, grew up near Runyon Canyon and learned the mechanical side of this trade at Los Angeles Trade-Technical College before spending well over a decade working on the older craftsman and Spanish-revival homes that line the hillside streets of Hollywood Hills. He started Carlton Chimney Sweep in 2015, and we’ve spent 11 years working on exactly the kind of chimneys Mid-Wilshire is full of: masonry flues built in the 1920s through 1940s, many with clay tile liners that haven’t been touched since.
That matters because a DuraFlex liner retrofit into an old clay flue isn’t a one-size-fits-all job. The liner has to fit the original flue properly, the top plate has to seal against a crown that may be eighty years old, and the insulation wrap has to stay put through seasons of light use and long stretches of nothing. We’ve seen enough loose top plates and pulled-away insulation in Mid-Wilshire duplexes to know exactly what to check before we ever climb onto the roof.
If we can see it, we can explain it. If we can explain it, you can decide what to do about it.

Common DuraFlex Chimney Cleaning Problems We Solve in Mid-Wilshire
Here’s what we actually find when we open up a DuraFlex-equipped chimney in this part of LA:
- Flex liner seams and joints separating. Mid-Wilshire fireplaces get used a handful of nights a year, which sounds gentle but means the liner goes through long cycles of heating and cooling with months of rest between. Over decades, that thermal cycling works joints loose, especially in decorative fireplaces that were never meant for heavy use.
- Insulation wrap degrading or pulling away. Older DuraFlex installs in Mid-Wilshire’s 1920s and 30s chimneys often have insulation wrap that’s sagged or pulled back from the liner near the damper. That leaves gaps where hot gases can contact framing, and in a duplex it’s not just your unit you’re protecting.
- Rust and corrosion on stainless liners in gas-converted fireplaces. When a decorative fireplace was converted to gas decades ago, the liner sees condensation that never fully dries in our mild, damp winter mornings. That condensation sits on stainless and eventually pits it, especially in fireplaces that barely get used.
- Top-plate and cap connections loosening at the crown. Santa Ana winds in the dry fall season drive dust and debris down unused chimneys, but the bigger issue is what happens at the crown. A top plate that was never properly sealed to the old masonry crown lets water and air into the annular space between the liner and the original clay flue.
- Bird and debris intrusion through failed caps. The same Santa Ana winds that push dust down a flue also carry twigs, leaves, and sometimes nesting material. A cap that’s loose or corroded at the top of a DuraFlex liner gives birds a way in, and once nesting material is in the flue it blocks airflow and creates a fire hazard.
DuraFlex Service in Mid-Wilshire: What Local Conditions Mean for Your Equipment
In the 90019 pocket near Wilshire/Western and the Carthay-adjacent blocks, a large share of the DuraFlex liners we see were retrofitted into 1920s and 30s Spanish Colonial and Tudor duplexes by previous owners or prior landlords. That means we regularly find liner sizing that doesn’t quite match the original clay flue, top-plate sealing that was never properly set against the old masonry crown, and insulation wrap that’s shifted out of position. A landlord preparing for tenant turnover needs documentation that the flue is sound or properly capped before a new renter moves in, and a liner that was dropped in years ago with loose hardware doesn’t pass that inspection.
We correct the fit, re-seal the top plate, trim and re-wrap insulation where needed, and provide the documentation a landlord can put in front of a property manager or tenant. It’s a distinctly Mid-Wilshire version of chimney work: the cleaning is often secondary to the verification that an older retrofit is still doing its job.
DuraFlex Models & Products We Service in Mid-Wilshire
We service the range of DuraFlex products found in Mid-Wilshire homes, including DuraFlex Pro stainless flex liner kits, DuraFlex ProFlex relining systems, DuraFlex insulated flexible chimney liners, and DuraFlex round and oval flex liner components. When we install or repair a DuraFlex system, we fit OEM-spec liners and components that match the original manufacturer’s dimensions and rating. Where OEM equivalents have been discontinued, we use quality aftermarket caps, top plates, and hardware without compromising safety.
That’s the practical reality of servicing older systems: sometimes the original part isn’t available anymore, and a quality replacement fitted correctly is the right call. We’ll tell you when a liner is sound and only a cap or top plate needs replacing, and we’ll be just as direct when relining is the safer option.

AfterDuraFlex Service Pricing in Mid-Wilshire
Every chimney is different, so we price by the job with a written estimate before any work begins. A standard chimney sweep and inspection in Mid-Wilshire typically runs $189 to $329, which includes the cleaning, a visual check of the flue, and documentation of what we found. Level 2 inspections, which use a camera to look inside the flue and are common before tenant turnover or a home sale, typically run $350 to $600 in this area.
Cap replacement for a DuraFlex-equipped chimney typically runs $225 to $485 depending on whether it’s a single-flue cap or a multi-flue cap spanning two or more liners. Multi-flue caps are common on Mid-Wilshire duplexes with side-by-side flues. What drives the cost most is access and condition: a 1920s chimney with a steep roof line and a crown that needs sealing work will take longer than a straightforward single-story run. Call (855) 731-2852 and we’ll give you a free estimate. The written estimate sets the final price, and nothing gets recommended without camera evidence you can see for yourself.

FAQs – DuraFlex Chimney Cleaning in Mid-Wilshire
Before tenant turnover, you need a documented Level 2 inspection that confirms the liner is intact, the top plate is properly sealed to the crown, and there’s no bird nesting or debris blocking airflow. In the 90019 corridor, we routinely find top plates that were never sealed correctly and insulation wrap that’s pulled away from the liner, both of which need correction before a flue can be documented as safe. Call (855) 731-2852 for a free estimate, and we’ll walk you through what the inspection covers.
Not inherently, but gas-converted fireplaces produce condensation that never fully dries in Mid-Wilshire’s mild, damp winter mornings, and that moisture sits on the stainless and can cause corrosion over years of light use. The bigger issue we see is that decorative fireplaces go long stretches without inspection, so a liner that was fitted decades ago may have loose seams or a sagging insulation wrap that nobody has looked at since. A Level 2 inspection answers whether the liner is still sound, and we’ll show you the camera footage so you can see it for yourself.
A multi-flue cap spans two or more flues, and in Mid-Wilshire duplexes with side-by-side chimneys it’s often the only way to keep birds, Santa Ana debris, and water out of both flues at once. If your duplex has separate flues for a fireplace and a furnace or water heater, a single-flue cap on each is an option, but a properly fitted multi-flue cap seals the whole crown and reduces the number of penetration points where leaks start. Call (855) 731-2852 and we’ll tell you which setup fits your roofline.
In most cases we can fix just the top plate. A loose or improperly sealed top plate is a sealing problem, not necessarily a liner failure, and we re-set and seal top plates regularly on Mid-Wilshire chimneys where prior owners dropped in a liner and never finished the seal against the old masonry crown. We’ll only recommend a full reline if the camera inspection shows cracked seams, corrosion through the liner wall, or other damage that compromises the flue. Call (855) 731-2852 and we’ll give you a straight answer.
Yes, and we see them constantly. A capped and sealed fireplace from the 1920s or 30s usually needs a full inspection to confirm the cap is still intact, the flue hasn’t been compromised by birds or debris, and no cracked clay tile is letting carbon monoxide or attic air into the living space. We’ll document what we find and give you the paperwork a landlord or home inspector would ask for. Call (855) 731-2852 for a free estimate.
