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.

If you own a home in Leesburg with a DuraFlex liner, cap, or crown and you’re seeing rust, water in the firebox, or spalling on the crown, this page tells you what’s actually going on, what it costs to fix, and what we document. Call (571) 601-3174 for a free estimate.
How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes solid products, but every liner system has weak points that show up in specific ways. Here’s what we see on DuraFlex jobs in Leesburg and how we address each one.
- DuraFlex 316L liner-to-cap connection corrosion. The stainless liner body holds up well, but the cap’s mounting collar is often the first point to fail because it sits directly in the weather. We remove the old cap, inspect the liner’s top edge for deformation, and install a replacement with a proper bead of high-temp silicone and mechanical fasteners, not just a friction fit.
- DuraFlex crown wash cracking at the flue opening. Crowns poured around DuraFlex liners often crack at the point where the liner passes through the crown, because the metal expands and contracts at a different rate than the concrete. We cut out the failed section, re-form the wash with a bonded sealant rated for flue gases, and slope the repair so water drains away from the liner instead of pooling against it.
- DuraFlex multi-flue cap wind noise. DuraFlex multi-flue caps with flat-welded hoods can whistle in Leesburg’s winter wind patterns, especially on exposed chimneys in the Potomac Station and Lansdowne areas. We adjust the hood angle and add a small wind band where needed. It’s a fifteen-minute fix that makes a big difference in a bedroom that backs up to the chase.
- DuraFlex deluxe cap mesh clogging with creosote or debris. The fine mesh on DuraFlex deluxe caps keeps animals out but catches creosote in wood-burning flues and cottonwood seed in spring. We remove the cap, clean the mesh down to the wire, and if the mesh is too far gone we replace it rather than tell you to live with reduced draft.
- Aftermarket cap mismatch on older DuraFlex oval-to-round adapters. Some Leesburg homes with 1990s-era DuraFlex systems have oval liners and adapters that generic caps don’t seat on correctly. We stock oval-compatible caps and when OEM isn’t available, we use aftermarket parts sized and rated to match, never a universal fit that leaves gaps for rain or sparks.
Our DuraFlex Chimney Cap & Crown Process
Here’s how a typical DuraFlex cap or crown job goes from first call to cleanup in Leesburg.
- 1
Call and written ballpark. You call, a live person answers, and we give you a written range for your cap or crown work before anyone sets foot on the property.
- 2
Camera-scan inspection. Our tech runs the camera down your DuraFlex liner and up through the cap area. This is an NFPA 211 Level 2 inspection, done on every visit, not an add-on.
- 3
Findings and written price. We show you the footage on-site, explain what we found in plain terms, and hand you a written scope and written price. Clause 1 of the Haven Standard requires this before work starts.
- 4
Parts decision. We tell you whether OEM DuraFlex makes sense or a quality aftermarket part does the same job for less, and we explain the warranty difference in writing.
- 5
The repair or replacement. Cap installation, crown repair, coating, custom cap fabrication for odd-sized flues, whatever the job calls for. We work carefully around existing liners and masonry.
- 6
Photo record and warranty. You get a documented photo record of the finished work, a written warranty, and our 365-Day Done Right Promise. If it’s not right, we make it right.

FAQs
A standard single-flue DuraFlex cap replacement in Leesburg runs $285 to $420 installed, while multi-flue DuraFlex caps run $480 to $780 depending on configuration. The price depends on flue size, existing liner condition at the top, and roof access. Call (571) 601-3174 for a free estimate and we’ll give you a written range before the visit.
No, installing a properly fitted replacement cap does not void a DuraFlex liner warranty, and we document the installation with photos so you have a record of what was done. If we’re using an aftermarket cap, we’ll explain the part in writing, including its rating and fit, so you know exactly what’s on your flue and why. The camera doesn’t lie, and neither does the price we write down before we start.
Most DuraFlex crown damage in Leesburg starts as cracking around the flue opening, and that’s repairable with routing and bonded sealant for $450 to $700 if we catch it before water gets under the crown. If the crown has spalled badly or is pulling away from the flue, a full recoat or rebuild is the honest call. We’ll show you the camera footage and give you the price for both options, so you decide with evidence, not a sales pitch.
Most standard DuraFlex cap replacements are done the same day once we’ve inspected and parts are on the truck, which is why we keep common sizes and oval-to-round adapters in stock. Custom caps take longer, usually a week to ten days for fabrication. Call (571) 601-3174 and tell us your flue size and current cap situation, and we’ll give you a realistic timeline in writing.
Yes, we also service HeatShield and Gelco liner systems, and we’ll tell you when an alternate brand part is the better value for your situation. We’re an independent DuraFlex service provider, not a factory rep, so we can be honest about when OEM matters and when an aftermarket part does the same job for less money. Every recommendation comes with a written price and a written warranty before work starts.
