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 Sherrelwood, CO
We provide independent DuraFlex service across Sherrelwood, from Level 2 inspections to creosote removal, crown repair, and liner work on flexible stainless systems. What sets our DuraFlex work apart here is the housing itself: most Sherrelwood homes are 1950s-70s ranches and tri-levels with clay tile flues that were never upgraded when inserts went in decades later. That mismatch is what we look for first. To book a sweep or an inspection, call (866) 361-5660. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.
Why Sherrelwood Residents Choose Us for DuraFlex Service
DuraFlex liners turn up in a lot of Front Range chimneys, and we’ve worked on enough of them to know where they give trouble. Early prefab units and insulated flue kits don’t fail the same way, and the fix isn’t the same either. That familiarity matters when the flue underneath is original 1950s clay tile.
We’re an independent DuraFlex service provider. We install, repair, and clean these systems with quality parts that fit them, and we work with DuraFlex components for critical connections and caps. Where the application calls for custom sizing, we use high-quality aftermarket stainless that meets the same standards. Nothing about that is guesswork: the liner is specified for your flue, not pulled off a shelf and made to work.
Scheduling is straightforward. We answer 24/7, dispatch Sunday through Friday from 7am to 7pm, and are closed Saturday. A call outside dispatch hours gets booked into the next opening.

Common DuraFlex Chimney Cleaning Problems We Solve in Sherrelwood
These are the DuraFlex issues we run into most in Sherrelwood, and each one connects to something specific about the local housing and weather.
- Clay tile cracking and spalling. Decades-old tile in the original masonry flue can crack and flake, and those rough edges sit right against the DuraFlex liner. Over time that’s abrasion, and premature wear on the liner wall. A Level 2 inspection tells us whether the tile is the problem or the liner already is.
- Undersized liners behind 1990s inserts. Plenty of Sherrelwood ranches had a wood insert added in the 1990s without resizing the flue. A DuraFlex liner sized for the old fireplace, not the insert, drafts poorly and collects creosote fast.
- Crown deterioration from freeze-thaw. Cold winters with rapid temperature swings work over the mortar joints at the crown. Once water gets behind the DuraFlex top plate, the liner starts to corrode. Crown repair is often what saves the liner.
- Misaligned connections in unlined or degraded flues. Original 1950s flues with no liner or failing tile can leave DuraFlex connections slightly out of line. Under thermal expansion, those joints separate. We check them during the sweep.
- Third-degree creosote from heavy seasonal use. Sherrelwood fireplaces get worked hard from October through March. That’s the kind of buildup that needs more than a brush pass, and it’s why we remove creosote as a dedicated step.
DuraFlex Service in Sherrelwood: What Local Conditions Mean for Your Equipment
Sherrelwood went in as a mid-century suburb, incorporated in 1953, and the housing stock shows it. Most streets are lined with small 1950s-70s ranches and split-levels, and many still have the original brick masonry fireplace with its clay tile flue. When a 1990s insert was dropped into one of those fireplaces, the flue underneath usually stayed as it was. So on a ranch along Pecos or Sherrelwood Drive, a Level 2 inspection almost always turns up the same thing: the insert’s venting needs and the original flue don’t match. Newer Denver suburbs rarely run into this, because their flues were built for modern appliances from the start. Here, it’s the default condition. For a DuraFlex owner, that mismatch is what drives poor draft and fast creosote buildup, and it’s why we inspect before we clean.
DuraFlex Models & Products We Service in Sherrelwood
We service DuraFlex Pro, DuraFlex Reline, DuraFlex Insulated, and DuraFlex Flex systems in Sherrelwood homes, along with the caps and top plates that go with them. That covers the range from older prefab units to insulated flue kits. When a component needs replacing, we match it to the liner and the flue it sits in. Critical connections and caps get DuraFlex components. Where the run needs custom sizing, we turn to quality aftermarket stainless that fits the application. If your existing liner is sound, we repair it and clean it. Replacement only comes up when the flue can’t be cleaned safely anymore.

AfterDuraFlex Service Pricing in Sherrelwood
What you pay depends on the work: a standard sweep on a DuraFlex-lined fireplace costs less than a Level 2 inspection plus creosote removal plus crown repair. The liner’s condition, the insert’s sizing, and how much creosote has built up all move the number. We set the price per job from a written estimate, and the estimate is free. You’ll know what’s being recommended and why before anything starts. If the work can safely wait, we’ll say so. Call (866) 361-5660 for an exact quote on your Sherrelwood chimney.

FAQs – DuraFlex Chimney Cleaning in Sherrelwood
Yes. A 1990s insert in a 1950s fireplace was often installed without resizing the flue, so the DuraFlex liner may be undersized for the insert’s venting needs. That shows up as poor draft and heavy creosote. A Level 2 inspection confirms it. Call (866) 361-5660 to schedule one.
Freeze-thaw cycles break down the mortar joints at the crown, and water gets behind the DuraFlex top plate, where it corrodes the liner and cap from the inside. Crown repair usually stops the cycle. Call (866) 361-5660 and we’ll look at the crown and the cap together.
Once a year, checked every season if you burn heavily from October through March. Heavy use builds creosote faster, especially with an undersized liner. Call (866) 361-5660 to book a sweep and we’ll tell you what interval fits your fireplace.
Often, yes. If the liner itself is sound, we repair around it and address the tile and crown rather than rebuild the chimney. Replacement only comes up when the flue is compromised past safe cleaning. Call (866) 361-5660 for an inspection first.
A Level 1 is a visual check of what’s accessible. A Level 2 goes further and is what we use when an insert was added, a liner changed, or a home changes hands, which describes a lot of Sherrelwood ranches. Call (866) 361-5660 to book the right one.
No. We’re an independent DuraFlex service provider, not affiliated with or authorized by the manufacturer. We service these systems with quality parts that fit them. Call (866) 361-5660 with your liner details.
