Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterDuraFlex Chimney Cap Installation: The Charlottesville Owner’s Guide
If you’ve got a DuraFlex chimney cap that’s rusted through, dented, or gone missing after a windstorm, we stock DuraFlex-compatible caps and install them across Charlottesville, typically for $285 to $465 installed, often the same week you call. Most people discover the problem the hard way: a rainy night and a drip down the chimney, or a bird scrabbling around in the flue at 6 a.m. The good news is a cap replacement is one of the more straightforward chimney jobs, and you don’t have to live with the leak while you decide what to do.
Which DuraFlex Models This Applies To
DuraFlex makes two cap lines that show up most often around Charlottesville: the standard round caps that fit their flexible liner kits, and the larger multi-flue caps built for masonry chimneys with multiple clay tiles poking through the crown. The critical measurement is the inside diameter of your liner or the outside dimensions of your flue tile, not the cap’s outside diameter, which is a mistake we catch on a lot of homeowner-supplied orders. On older DuraFlex liner systems from the mid-2000s, the cap base can corrode enough that the screw holes no longer line up, which means a newer OEM cap will not seat properly without a base plate adapter. We stock both OEM DuraFlex caps and a quality aftermarket equivalent from Olympia, and we will honestly tell you when the aftermarket part is actually the better buy, because sometimes it is. Top Hat Chimney is an independent local shop, not a DuraFlex dealer, so our recommendation is based on what fits and lasts, not what the manufacturer pushes.
Signs Your DuraFlex Chimney Cap Installation Is Failing
- Water dripping from the damper or firebox after rain. This usually means the cap’s spark arrestor mesh has rusted through and is letting rain straight down the liner. In Charlottesville’s humid summers, that mesh corrodes faster than people expect.
- Black streaks staining the chimney crown or brickwork. That is creosote-laced water wicking down from a cap whose seams have opened up. It is not just cosmetic; that water is getting inside the structure.
- Bird or squirrel activity in the flue. The mesh on a DuraFlex cap will eventually open up at the welds, and once a squirrel finds its way in, you will hear it. The cap needs replacing, not patching.
- Cap listing or sitting off-level. High winds off the Blue Ridge shift caps that were never properly secured to the liner, and once the cap leans, every rain event sends water into the chase.
- Creosote buildup even when you burn seasoned wood. A partially blocked or undersized cap chokes the draft, which causes creosote to settle in the liner instead of venting out. If your wood is good but your liner is glazing up fast, the cap is often the bottleneck.
Replacement Cost & What’s Included
For a standard DuraFlex-compatible round cap on a single liner, Charlottesville homeowners are looking at $285 to $465 installed. The range depends on whether you need a plain cap or one with a taller spark arrestor, whether the liner needs a base plate adapter, and how accessible the roof is. The price we quote on the phone includes the cap, the fasteners, the labor, and the trip, and it is the number on the invoice, because Wendell has run this shop on the belief that a man should not have to barter at his own chimney. Every cap job is covered by our 90-Day Done Right Promise: if the cap shifts, leaks, or loosens within three months, one call brings Wendell and his crew back at no charge. We also honor the standing offers: $40 off any repair over $200, and 10% off for seniors and veterans.
DIY or Call Us?
If your cap is simply missing and the liner is accessible from a low-slope roof, a capable homeowner can measure the liner diameter, order the right cap, and set it with stainless screws. The problem is that most Charlottesville chimneys are not low-slope, and a wet roof over a two-story gable is no place to learn balance. The bigger issue is diagnosis: if the cap failed because the liner top is out of round or the crown is crumbling underneath, a new cap will not fix the root cause. We have seen enough DIY caps blow off in the same season they went on. If you want us to look at it, call (540) 503-3890 and we will bring a camera, show you what is happening, and give you a straight answer with a price. If it does not need doing, I will tell you.
FAQs
A stainless DuraFlex cap in Charlottesville’s climate typically lasts 8 to 14 years before the mesh or seams fail, though caps on wood-burning flues that see heavy creosote exposure can go in 5. The humidity and the freeze-thaw cycle through winter are what kill them, not the firebox. Call (540) 503-3890 if yours is at the edge of that range and we will take a look.
In our experience, no. Once the mesh separates from the band or the seams open up, the metal is too thin to weld reliably, and a patch just becomes a second leak point. Replacement is cheaper over time. Call (540) 503-3890 for an exact quote, and a free estimate.
A straight single-liner cap swap takes about an hour once we are on the roof. Most Charlottesville jobs are done the same visit, no return trip needed. Call (540) 503-3890 to schedule a time.
Yes. We carry the most common DuraFlex-compatible round cap sizes, as well as caps and liners from HeatShield, Olympia Chimney, Gelco, Famco, and Copperfield. If you have an uncommon size, we can order it in for a second visit. Call (540) 503-3890 and we will tell you over the phone whether yours is on the truck today.
If you have a DuraFlex cap that is leaking, rusted, or gone, call Top Hat Chimney at (540) 503-3890. We will give you a real price before any work starts, and the work is backed in writing.
