Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Redlands Residents Choose Us for DuraFlex Service
DuraFlex stainless liner systems hold up well across the Inland Empire, but they age differently on a Smiley Park Craftsman than they do on a 1980s tract home near the University of Redlands. We’ve relined and re-capped hundreds of DuraFlex assemblies in both, and we offer the same DuraFlex service in Mentone. That local repetition matters. We know which failure modes show up in which neighborhoods, and we stock genuine DuraFlex caps, top plates, and clamps so common repairs in Redlands don’t require two service visits.
Allen Prescott grew up near the Kendall Drive corridor in San Bernardino and has spent the better part of three decades working chimneys across the Inland Empire. He built this company around one principle: a homeowner who understands the hazard takes the maintenance seriously. That’s why we’re the DuraFlex sales & service provider Redlands homeowners call when they want straight answers about their liner, not a sales pitch.

Common DuraFlex Chimney Cleaning Problems We Solve in Redlands
- Loose or rusted termination caps on Craftsman chimneys. In Smiley Park and Brockton Heights, the original brick chimneys don’t give a stainless cap much flat surface to bite into. After enough seasons of Santa Ana wind-driven grit, the cap loosens or the mounting screws strip out. We see this on nearly every older Redlands home with a DuraFlex-lined flue. The fix is usually a new cap and proper re-seating, done the same visit as the sweep.
- Hardened creosote after months of idle fireplaces. Redlands summers are hot and dry, and most fireplaces sit unused from April through October. Creosote doesn’t blow away during that time. It bakes onto the stainless liner wall and hardens. A standard brush job doesn’t always cut it on a DuraFlex liner that sat through a hot inland summer. We bring rotary tools for exactly this.
- Insulation blanket degradation on insulated DuraFlex liners. The insulation wrap on a DuraFlex insulated liner gets brittle after years of heat cycling. Inside older Redlands chases, especially in the unlined single-wythe brick chimneys near downtown, that degradation eats into the UL-listed zero-clearance protection. We inspect the blanket during every Level 2 and flag when it’s compromised.
- Corroded flex liner seams at the flue top. Santa Ana winds drive soot and moisture back down flues in Redlands, and that debris collects where the stainless flex sections join at the top. Over multiple seasons, those seams corrode. It’s a specific failure mode we see more in Redlands than in Fontana or Crestline because of the wind exposure.
- Liner connections that separate during insert swaps. When a homeowner has a wood insert pulled and a different unit installed, the appliance collar connection on the DuraFlex liner often gets crushed or yanked loose. We’ve walked into Redlands homes where the liner was hanging an inch off the collar. You can’t safely sweep that condition. We re-fit the liner first, then clean.
DuraFlex Service in Redlands: What Local Conditions Mean for Your Equipment
Here’s the thing most generic chimney pages won’t tell you about Redlands. In the Smiley Park and Brockton Heights neighborhoods, the original 1920s orange-grove-era brick chimneys routinely fail the city’s seismic retrofit standards when mortar starts crumbling. That means a DuraFlex cleaning call on those homes doesn’t typically end with a quick sweep. The home has a stainless liner system, sure, but the structure holding it is century-old mortar and brick that may not have seen repointing since the Eisenhower administration. So the actual scope of work on a Smiley Park DuraFlex job is often: inspect the liner, clear the creosote, re-secure the top plate, and then have a straight conversation about the masonry that surrounds the liner. On a tract home east of the 210 in 92374, by contrast, the chimney is typically factory-built metal with no masonry at all, so the DuraFlex work is mostly liner cleaning and cap replacement. The neighborhood changes the job before we even climb the ladder.
DuraFlex Models & Products We Service in Redlands
We work on the full DuraFlex lineup for Redlands homes. That includes the DuraFlex SW stainless flexible relining kit for masonry chimneys, the DuraFlex Pro flexible stainless liner system, and DuraFlex insulated flexible liners for zero-clearance applications and wood insert retrofits. We also replace DuraFlex stainless chimney caps and multi-flue caps. Our approach to parts is simple. When a factory-match matters for clearance and listing, we fit genuine DuraFlex liners, caps, and top plates. When an aftermarket cap or clamp performs equivalently, we say so and save you the money. We stock common DuraFlex caps and clamps for fast Redlands turnaround, so most cap and top plate replacements happen the same day as the sweep, and we carry that same inventory for DuraFlex repair in Loma Linda.

AfterDuraFlex Service Pricing in Redlands
A DuraFlex chimney cleaning in Redlands typically runs $175 to $325 for a standard Level 1 sweep, depending on liner length, creosote stage, and whether the cap needs replacement. If a Level 2 camera inspection is needed because of a recent home sale, an insert swap, or suspected liner damage, that adds $150 to $300. Cap replacement on a DuraFlex system in Redlands generally runs $65 to $180 for the cap and installation combined. The wildcard is liner work. Insulated relining or liner replacement is quoted case by case because every old Redlands chimney presents different clearances and crown conditions. We give you a flat price before any work begins, and the estimate is free. Call (877) 516-7159 and we’ll walk you through what your specific setup will cost.

FAQs – DuraFlex Chimney Cleaning in Redlands
Yes, and here’s why. A DuraFlex liner is stainless steel, and stainless steel fails at its connections, not along its body. The top plate, the cap, the appliance collar, the insulation wrap. A Level 2 camera inspection shows you those specific failure points. On a Smiley Park home, we’re also looking at the masonry surrounding the liner, because the seismic retrofit standards in Redlands apply to the chimney structure, not the liner inside it.
Wind. The Santa Ana winds that come down through the Cajon Pass and across the east side of Redlands put constant lateral pressure on chimney caps. Add in the thermal expansion and contraction of metal against metal, and the cap’s screws and mounting feet work themselves loose over a season or two. We fix this with proper re-seating and, where the mounting surface allows, upgraded clamp hardware. It’s a quick fix that prevents water and debris from dropping down into your DuraFlex liner.
Yes, with the right tools and experience. Standard wire brushes are too aggressive for the insulation wrap on a DuraFlex insulated liner. We use poly brushes and controlled rotary tools that remove creosote without tearing the blanket. We also inspect the blanket during the sweep to confirm it hasn’t already degraded from heat cycling. Call (877) 516-7159 if you want us to look at yours.
Worse than you’d think. What was loose, flaky creosote in April becomes a baked-on, glazed layer after six months of hot inland air. That hardened creosote is harder to remove and more flammable than the loose stuff. If you’re in Redlands, a pre-season sweep in October or early November isn’t overcaution. It’s the difference between a routine clean and a heavy removal job. Call (877) 516-7159 before the first cold night.
We do both. We sweep, we repair, and we reline. When a DuraFlex-lined chimney in Redlands has spalling brick or crumbling mortar, we’re set up to address it without sending you to a second company. We find it and we fix it. That’s been the model since day one.
