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 Upland, CA | Chestnut Chimney Sweep
Independent DuraFlex chimney cleaning and service across Upland costs $189 – $325 for a standard sweep, with Level 2 inspections typically running $250 – $450 depending on what we find. The one thing that makes our DuraFlex work different here: we’ve seen how Upland’s Santa Ana winds and long idle seasons abuse these systems, so every cleaning starts with a cap and top-plate check that most sweeps in town skip. You don’t just get a brushed flue. You get a system check aimed at what actually fails on DuraFlex equipment in this specific foothill climate. Call (855) 360-4975 for a free estimate.
Why Upland Residents Choose Us for DuraFlex Service
Roland Cifuentes has spent nearly two decades working chimneys across the Inland Empire, and DuraFlex liners and caps are a major part of what we see. We’re not a manufacturer-authorized shop, and we’ll say that plainly. What we are is a DuraFlex sales & service team that knows these systems at the field level: how the twist-lock joints seat, where the top plate fasteners loosen, what a wind-damaged cap looks like before it fails entirely.
When you call us in Upland, you get someone who can name the part that’s failing and tell you whether it’s worth replacing or can safely wait. We stock genuine DuraFlex OEM caps, top plates, and liner components when they’re available, and we use aftermarket stainless parts that meet or exceed original specs when OEM is backordered. You’ll know which one you’re getting and why.
We carry DuraFlex, Copperfield, Gelco, and Olympia Chimney products because the parts matter as much as the labor. That’s the whole point.

Common DuraFlex Chimney Cleaning Problems We Solve in Upland
Here’s what we actually find on Upland roofs, street by street:
- Wind-loosened caps and packed mesh screens. After a spring of Santa Ana winds, DuraFlex caps in the 91784 foothills are often loose at the fasteners or jammed with leaves and dust. We see bird nests behind those screens more often in Upland than anywhere else we work. Cap replacement and mesh clearing are a routine part of our cleaning calls here.
- Joint separation and corrosion at the top plate on stainless flexible liners. Mid-century ranch homes in Upland have a recurring issue: dust and ash collect at the top plate, hold moisture through our occasional winter rains, and stress the liner joints. We spot this early during a cleaning, and it’s often repairable before it becomes a full reline job.
- Gaps at twist-lock joints in 1980s – 2000s tract homes. Heating and cooling cycles in Upland’s hot summers and cold snaps cause insulated chimney sections to shift. When a twist-lock joint gaps, creosote seeps behind the liner where you can’t see it. That’s a fire hazard, and it’s one reason we push Level 2 inspections on any DuraFlex system that’s been quiet for years.
- Seized dampers and rusted assemblies from idle seasons. Upland chimneys sit unused for most of the year. That sounds like it should mean less wear, but it doesn’t. Dampers seize, cap assemblies rust, and rarely-used systems need more attention at inspection time than ones that run regularly.
- Cracked and offset clay-tile flues discovered during relining. Older downtown Upland bungalows frequently have original clay flues that were never meant for modern wood burning. When we open the chimney to prep for a DuraFlex liner, we often find cracked tiles. That’s not a cleaning problem, but it’s a discovery that changes the whole plan.
DuraFlex Service in Upland: What Local Conditions Mean for Your Equipment
Upland’s downtown bungalows, the Craftsman and Spanish Colonial homes near Euclid Avenue and the older streets around the Metrolink station, have a problem you won’t find in the newer subdivisions to the north. Many of them still run original clay-tile flues that were laid when the house was built, long before modern liners existed. A cleaning in these homes is rarely just a cleaning. When we drop a camera down one of those flues before installing a DuraFlex liner, we’re looking for cracked or offset clay tiles, and we find them more often than not. That’s why Upland service area homes from the 1920s through the 1940s so often need a full Level 2 inspection and relining before the first fire of the season. The cold snap hits, the homeowner lights a fire for the first time in eight months, and the hidden crack in that old clay flue lets heat reach framing. We’d rather find it in September.
DuraFlex Models & Products We Service in Upland
We work on the full DuraFlex range you’re likely to find in Upland homes and in DuraFlex in Rancho Cucamonga installs: SS flexible chimney liner kits, Sure-Temp insulated chimney systems, DuraLiner relining kits, and both round and square termination caps. If you’ve got a factory-built fireplace from a 1990s tract build or a recently relined masonry chimney, we’ve likely seen your exact setup before.
Our parts approach is simple. We install genuine DuraFlex OEM components when we can get them. When OEM is backordered, we use quality aftermarket stainless that matches or exceeds the original spec, and we tell you which option you’re getting before any work starts. No anonymous parts, no mystery metals.
On a foothill street in the 91784 ZIP, we opened a DuraFlex cap that was packed solid with bird nest material and leaves after the spring winds, and found the stainless liner’s top plate had pulled loose — a pattern we also see on DuraFlex service in Montclair foothill homes. We replaced the cap with a new DuraFlex multi-flue model, reseated the top plate, and ran a Level 2 inspection before the homeowner’s first winter fire. That’s what we mean when we say we clean chimneys here differently.

AfterDuraFlex Service Pricing in Upland
Standard DuraFlex chimney cleaning in Upland runs $189 – $325, depending on the system’s size, accessibility, and how long it’s been since the last sweep. Level 2 inspections typically cost $250 – $450. Cap replacement, when needed, adds $120 – $300 for parts and labor depending on whether you need a single-flue or multi-flue unit. Liner repairs run $400 – $1,200 per section, and a full DuraFlex reline of an older Upland bungalow’s clay flue typically lands between $2,800 and $6,000 because of the prep work involved with cracked existing tiles.
What drives your price: two-story roofs cost more to access, foothill homes with steep pitches add time, and systems that have been idle for years usually need inspection work beyond a basic sweep. Every estimate starts with a free phone consultation, and we’ll give you a flat price before we book. Call (855) 360-4975 and we’ll talk through what your system needs.

FAQs – DuraFlex Chimney Cleaning in Upland
Turn off any fires and stop using the fireplace until the cap is inspected. A loose cap after high wind can allow debris, birds, or rain into the flue, and a dislodged top plate can let hot gases reach places they shouldn’t. We check cap fasteners, mesh screens, and top-plate seating on every Upland call for exactly this reason. Call (855) 360-4975 and we’ll get someone out to assess it before you light another fire.
If your Upland home is getting its first cleaning in several years, if you’ve just bought the house, or if Santa Ana winds have visibly affected your cap, you need a Level 2 inspection. A Level 1 is fine for a chimney that’s cleaned regularly and shows no signs of trouble. Our default recommendation for Upland’s idle systems and wind season aftermath is Level 2, especially on older downtown homes with original clay flues. Call (855) 360-4975 and we’ll help you decide based on your system’s history.
At least once per year, and we recommend scheduling it before the first cold snap, not after. Upland’s dry inland climate means chimneys sit idle most of the year, then get worked hard in short winter bursts. Any creosote that accumulated last season has had months to sit and harden. Annual cleaning before burn season is the standard, and homes that burn frequently through winter sometimes need a second mid-season sweep.
Yes. We remove nesting material during the cleaning, inspect the cap and mesh for damage, and recommend a replacement cap if the original has been compromised. For Upland foothill homes in 91784, we often suggest upgrading to a multi-flue cap with heavier mesh screens that stand up better to wind-driven debris. The goal is a cap that stays clear of nesting material through the next windy spring.
Yes, and that’s one of the most common jobs we do in Upland’s downtown neighborhoods, along with DuraFlex repair in Claremont and surrounding areas. The process starts with a camera inspection to check for cracks or offsets in the existing clay tiles, and if we find damage (which we usually do), we’ll recommend a full reline with a DuraFlex stainless liner sized for your fireplace and fuel type. It’s a larger job than a cleaning, but it brings an older chimney up to safe modern standards. Call (855) 360-4975 for a free inspection estimate.
