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 Valley Glen, CA | San Bernardino Chimney Sweep
We clean, scope and repair DuraFlex chimney systems across Valley Glen as an independent service provider, and we provide Encino DuraFlex service as well. The work here is different because the 1940s – 1960s tract homes that define Valley Glen were built with repeated clay-tile flue patterns, and after the 1994 Northridge quake, a lot of those tiles shifted. That means a DuraFlex liner seated inside one of those original flues often needs more than a brush-out, and that’s exactly what we look for before we ever put a brush up the shaft. Call (877) 516-7159 for a free estimate.
Why Valley Glen Residents Choose Us for DuraFlex Service
We pull, scope and reline DuraFlex flexible stainless systems inside post-war masonry chimneys on a regular basis, and we know how these liners seat inside original clay-tile flues and where they fail. This isn’t a sideline for us. Chimney sweeping, chimney repair and dryer vent cleaning are what we do, and we use contractor-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco and Copperfield rather than whatever is on the hardware store shelf.
Allen Prescott, our owner, grew up near the Kendall Drive corridor in San Bernardino and has spent the better part of three decades on Inland Empire chimneys. He built the company on straight talk: we tell you exactly what we found in your flue, why it matters, and what actually needs to be done versus what can wait. When we inspect a DuraFlex system in Valley Glen, we treat it like a system with a history, because around here it always has one. For broader DuraFlex sales & service context, this is the work we do every week.

Common DuraFlex Chimney Cleaning Problems We Solve in Valley Glen
- Liner-to-top-plate seals that failed or were never fitted right. We find this a lot on Valley Glen chimneys where the original clay flue settled and pulled the top plate loose. Rain and Santa Ana grit then run down the outside of the stainless and load the annular space, which saturates the masonry and rusts the liner from the outside in. We check that seal on every cleaning.
- Spark-arrestor screens packed with leaf litter and nest material. After a big Santa Ana wind event, Valley Glen flue tops catch everything that blows through the mid-Valley. A DuraFlex termination with a mesh arrestor can look clean at the firebox and still pull no draft because the screen is choked solid. Cap Replacement is a common follow-up to our Level 2 Inspection here.
- Rust-through at seam joints and tee connectors. This shows up on older DuraFlex runs where the liner sits inside a cracked clay flue that stays damp from rain intrusion or a missing top seal. Valley Glen’s hot, dry summers hide the rust, then the first cool evening reveals a draft problem. Creosote Removal alone won’t fix it, and we won’t pretend it will.
- Liner sections shifted or disconnected at the top. The 1994 Northridge quake cracked and offset original clay tiles in many Valley Glen homes. When a DuraFlex liner was installed inside a flue that later shifted again, the connection at the top can open up. We scope the shaft before assuming a brush-out is enough.
- Wrong-size aftermarket caps on multi-flue terminations. A universal cap dropped on a DuraFlex multi-flue setup doesn’t seal what it should. We fit caps and top plates matched to the flue diameter, including custom fits when a Valley Glen chimney needs it.
DuraFlex Service in Valley Glen: What Local Conditions Mean for Your Equipment
Here’s the thing most generic DuraFlex pages never tell you. Valley Glen’s 1940s – 1960s mid-Valley tract homes were built to a handful of repeated clay-tile flue patterns. If a cracked or shifted tile from the 1994 Northridge quake is present on one street, there’s a good chance the same offset exists in the DuraFlex liner seats on the next street over, because the builders repeated the same flue design block after block. That means a liner that still looks sound from the firebox can be disconnected or kinked at the top where the original tile broke. We scope the shaft before assuming a brush-out. This is the difference between a cleaning that lasts a season and a cleaning that finds the problem before it becomes a chimney fire or carbon monoxide issue. Our Valley Glen service area work starts with that assumption, not with a bucket of brushes.
DuraFlex Models & Products We Service in Valley Glen
We service the DuraFlex Pro flexible stainless relining kits, both factory-insulated and uninsulated, along with DuraFlex rigid stainless pipe sections used for top-term runs above the roofline. We also work on DuraFlex multi-flue and single-flue termination caps with mesh spark arrestors, plus DuraFlex top plates and storm collars that seal liner tops at the crown.
For parts, we use DuraFlex-spec stainless components and quality aftermarket caps and top plates matched to the flue diameter. We won’t drop a universal cap on a liner that needs a custom or multi-flue fit, because that’s how you end up with the problems we get called to fix. If a liner is corroded through or disconnected at the top, we say so and quote the reline rather than brush it and hope. We find it and we fix it.

AfterDuraFlex Service Pricing in Valley Glen
A DuraFlex chimney cleaning in Valley Glen typically runs $160 – $220 for the sweep itself, with the camera scope adding $85 – $150, and cap replacement falling between $120 – $300 depending on flue diameter and whether it’s a single or multi-flue fit. What drives the cost here is access: many 1950s Valley Glen chase tops are tight, and the clay-tile offsets from the Northridge quake often mean we’re scoping before we brush.
We give a flat price before we book, and the free estimate includes everything we plan to do. No add-ons you didn’t approve. Call (877) 516-7159 and we’ll map out what your chimney actually needs.

FAQs – DuraFlex Chimney Cleaning in Valley Glen
Yes, and in many Valley Glen homes that’s exactly the right fix. A DuraFlex flexible stainless liner can be pulled through a flue with cracked or offset clay tiles, as long as the shaft still has a clear path, and the liner then carries the exhaust independently of the damaged masonry. We scope the flue first to check for offsets from the Northridge quake that would need a rigid section or a different approach. A cracked tile doesn’t always mean a full tear-out. Call (877) 516-7159 and we’ll tell you what we see.
Because the termination cap’s spark-arrestor screen gets packed with wind-blown leaf litter, grit and sometimes a bird nest, and that chokes the draft even when the firebox and liner look clean. This is a common pattern in Valley Glen after big wind events. The fix is pulling the cap, clearing the debris, and checking the liner underneath for anything the wind shifted. A screened cap that’s clear restores the draft the same visit.
We run a camera down the liner and look for three things: creosote buildup past a certain thickness, rust-through at seam joints or tee connectors, and any section that’s shifted or disconnected at the top. Creosote we can clean. Rust-through or a shifted connection means the liner has failed as a system and should be relined. We’ll show you the camera footage so you can see what we see before anyone quotes a repair.
In Valley Glen, a fall sweep is the minimum, but it should include a check of the DuraFlex top seal and termination cap, because your chimney spent months exposed to hot, dry weather and whatever the Santa Ana season blew into it. We also offer DuraFlex repair in Sherman Oaks with the same thorough approach. The firebox can look fine while the cap screen is packed solid and the top plate seal has failed. A quick sweep plus a Level 2 Inspection catches the stuff the brush alone won’t. Call (877) 516-7159 for a free estimate before burning season.
Yes, and that’s a setup we see in some Valley Glen homes where the original clay tiles were never installed. The DuraFlex liner becomes the flue in those cases, so its condition is everything. We scope those systems carefully, because there’s no clay tile behind the liner to catch problems, and a rust-through means exhaust is moving through the chase itself. We’ll tell you plainly whether the liner is serviceable or needs a reline.
