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 & Crown in Annapolis: What to Know First
Independent DuraFlex chimney cap and crown service in Annapolis typically runs $285 to $680 for a cap replacement and $450 to $1,200 for crown repair or coating, with most jobs completed in a single visit. We’re not affiliated with DuraFlex, but we’ve installed and repaired their caps and crowns for years, and we know exactly where these products fail in a salt-air, freeze-thaw climate. If you own a DuraFlex cap or crown in Annapolis and it’s leaking, rusting, or loose, call (240) 851-3653 and Wendell will give you a straight answer on whether it needs fixing at all.
This page is for homeowners who already have DuraFlex equipment on their chimney and want someone who knows the product line well enough to tell an OEM part from a knockoff and a warranty issue from normal wear. If you’re not sure what brand you have, we’ll identify it during the inspection and tell you what we’re looking at.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex stainless caps rusting at the base ring. The 304-series stainless caps hold up against rain, but the base ring where the cap meets the flue tile collects salt spray and condensation here in Annapolis. We see rust bleeding down the flue tile well before the mesh screen gives out. The fix is a replacement cap with a properly sealed base, and we always check the flue tile underneath before putting anything new on.
- Cracked crown on a DuraFlex multi-flue installation. Multi-flue caps sit on a concrete crown, and when the crown cracks, the cap can actually hold moisture against the crown instead of shedding it. That accelerates the freeze-thaw damage you get in Maryland winters. We repair and coat the crown first, then reset or replace the cap so water can’t pool around the mounting legs.
- Loose or missing cap screws on the DuraFlex Liner Kit connection. The cap that comes with a standard DuraFlex liner kit threads onto the liner itself, and if the installer used the wrong fasteners or didn’t seat the cap flush, wind vibration loosens it over time. You’ll hear a rattle in high wind that comes and goes. We check the liner connection for deformation and re-seat the cap with the right hardware.
- Warped mesh on side-draft caps near the water. Homes close to Back Creek and College Creek get constant damp, sandy wind. The mesh on screened caps corrodes faster there, and once the gaps open up, birds and squirrels are in. A warped screen means the cap has been doing its job, but it’s time for a replacement. We keep common DuraFlex cap sizes in the truck.
- Missing or cracked chimney crowns on older DuraFlex retrofits. We run into a lot of homes in the Historic District where a DuraFlex liner and cap were retrofitted onto a chimney from the turn of the century. Those old crowns weren’t poured over the liner the way modern ones are. Hairline cracks let water get between the brick and the liner chase. We recoat the crown with a flexible sealant that moves with the brick and stop the leak at the source, not just at the cap.
Our DuraFlex Chimney Cap & Crown Process
Here’s what a typical DuraFlex cap or crown job looks like when you call Top Hat Chimney in Annapolis:
- 1
The call. Wendell or a member of the crew answers the phone, asks what you’re seeing, and gives you a range on the spot. No call center, no scheduler reading a script.
- 2
The look. We get on the roof and pull the cap if we need to. Camera footage of the flue and crown goes on the report every single time.
- 3
The verdict. We show you exactly what we found: cracked crown, rusted base, loose liner connection. If it doesn’t need replacing yet, we’ll tell you that too.
- 4
The decision on parts. OEM DuraFlex parts when the job calls for it, quality aftermarket when it genuinely matches or improves on the original without voiding anything. We walk you through the tradeoff before any work starts.
- 5
The work. We set the new cap, repair or coat the crown, seal the base, and make sure the liner connection is rock solid. One visit in almost every case.
- 6
The guarantee. Every job gets the 90-Day Done Right Promise in writing. If something isn’t right, one call brings us back at no charge.
What DuraFlex Chimney Cap & Crown Costs in Annapolis
Straight numbers, because that’s how we price everything.
- Single-flue stainless cap replacement: $285 to $425 installed, depending on flue size and roof access.
- Multi-flue cap replacement: $550 to $850, more if we need to reinforce the crown as part of the install.
- Crown repair with flexible coating: $450 to $900, based on crown size and how much prep work the old surface needs.
- Full crown rebuild and recap: $1,050 to $1,200 for a badly cracked crown that has to be reformed before the cap goes back on.
What moves the price in Annapolis? Roof pitch and height are the big ones. Three-story homes in the Historic District with a steep slate roof take longer to access than a single-story rancher in Hillsmere. The condition of the crown matters too: a simple recoat is fast, a rebuild is not. You get the exact number before any tool comes off the truck, and that number is the number on the invoice. Call (240) 851-3653 for a free estimate on your DuraFlex cap or crown.
Why Annapolis Homeowners Call Top Hat Chimney for DuraFlex Work
Wendell Pike has been crawling across roofs in and around Annapolis since 1999, and he’s run into enough DuraFlex equipment to know the failure patterns by heart. You’re not getting a rotating crew from a national outfit that quoted you one number on the phone and another at the door. You get Wendell and his crew, a published license number, and a face you’ll see at the hardware store next weekend.
Every DuraFlex job is backed by the 90-Day Done Right Promise in writing. If the cap leaks or the crown coating peels, one call brings us back. No fighting, no re-quote, no voicemail maze. The phone is answered by a live person around the clock. And if a DuraFlex cap turns out to be the wrong fix for your chimney, we’ll tell you. Sometimes the problem isn’t the cap at all: it’s a failing crown or a liner issue better handled with a HeatShield resurfacing or a Gelco crown coat. We service those too, so you get an honest recommendation, not a sales pitch for the one product we happen to sell.
FAQs
Replacing the cap itself won’t void a DuraFlex liner warranty, as long as the replacement is compatible with the liner’s diameter and connection type. Keep your original invoice, and if you have active warranty coverage, we’ll help you document that the work was done to manufacturer spec. Annapolis homes with retrofitted liners from the early 2000s are often past warranty anyway, but we’ll tell you if you’re still covered before we touch anything.
We can match your existing DuraFlex cap in most cases. The common sizes for single-flue and multi-flue setups are readily available, and if you want OEM DuraFlex, we’ll order it and have it ready before the install date. When an aftermarket cap is a better value or actually outlasts the original in a salt-air environment, we’ll show you the difference and let you decide.
If the crown has a few hairline cracks and the concrete is still solid, you should repair and coat it. This is a $450 to $900 job. If chunks are missing, the crown is soft enough to crumble under thumb pressure, or water has clearly been getting behind the brick for seasons, you should rebuild. We always show you camera footage of the crown before recommending a rebuild, so you can see the damage with your own eyes. Nothing gets recommended without proof.
Most cap replacements can be scheduled within a week, and simple single-flue jobs are often done the same week you call. If you’re seeing active water intrusion or you’ve caught animals getting in through a deteriorated mesh screen, call (240) 851-3653 and we’ll work you in with urgency. We cover Annapolis and the nearby communities without a trip charge inside the county.
Water gets into the flue and the brickwork, and in Annapolis the freeze-thaw cycles through January and February will open every crack wider. A rusted cap base eventually lets water run down the outside of the liner and pool at the smoke shelf, which leads to rust on the damper and damp smells in the firebox. A cracked crown does the same from the top down. If it doesn’t need doing yet, we’ll say so. If it needs doing, don’t wait another winter. Call (240) 851-3653 and we’ll give you the straight answer.
