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.
DuraFlex Chimney Cap & Crown in Fort Worth: What to Know First
We provide independent DuraFlex chimney cap and crown service across Fort Worth, from the Cultural District to Ridglea, with written estimates delivered before any work starts and a 365-Day Done Right Promise on every job. Most DuraFlex cap replacements and crown repairs are completed in a single visit once parts are confirmed, and we’ll tell you honestly when a repair can wait versus when water intrusion is actively damaging your liner. This page is for homeowners who’ve confirmed or suspect their chimney cap or crown is DuraFlex-branded and want to know what failure looks like, what fixing it costs, and who to call without sitting through a sales pitch. Questions? Call us at (682) 499-2712 - a live person answers, day or night.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW stainless caps: weld-seam separation at the skirt. The SW series uses a rolled skirt joint that holds up well in dry climates but takes a beating from Fort Worth’s spring hail and summer thermal cycling. We see the skirt pull away from the mesh body, creating a gap that funnels water directly onto the crown. Our fix: source a replacement SW cap with reinforced skirt welding from our Haven buying network, or step up to a Gelco equivalent when the flue configuration allows. We photograph the gap before and after so you see the water path.
- DuraFlex DSA multi-flue caps: sagging lid from undersized support struts. The DSA line ships with struts rated for standard snow load, but Fort Worth ice events in 2021 and 2023 overloaded units on north-facing roofs. The lid tilts, ponding water accelerates crown spalling underneath. We replace with OEM-spec DSA struts or upgrade to heavier-gauge aftermarket supports - your call, with both prices in writing before we start.
- DuraFlex standard galvanized caps: rust-through at the drip edge in 4-6 years. Galvanized caps in Fort Worth’s alkaline rain (pH trends higher here than East Texas) lose protection at the cut edge first. By the time you see rust on the lid, the drip edge is already bleeding onto the crown. We pull the cap, assess crown damage with the camera, and quote stainless replacement plus any crown coating needed. No point in a new cap if the crown underneath is funneling water past it.
- DuraFlex crown coatings: delamination from application over active moisture. DuraFlex’s crown sealant products perform well when applied to a dry substrate, but we’ve found multiple Fort Worth jobs where a previous contractor coated over damp concrete or applied too thin at the flue interface. The sealant bubbles, cracks at the flu collar, and traps worse moisture than it prevents. Our fix: mechanical removal, 48-hour dry time with moisture meter verification, then reapplication to DuraFlex spec thickness - 1/8″ minimum, feathered at the edges.
- DuraFlex flue collar adapters: cracking at the cement-tighten joint on factory-built chimneys. The collar that mates DuraFlex caps to certain factory-built flue systems uses a cement-tighten ring that fatigues after 8-10 years of expansion cycles. In Fort Worth’s clay-heavy soils, chimney settlement adds shear stress. We replace with a stainless collar adapter, sealed with high-temp silicone rated to 600°F, and document the flue wall condition with the camera while we’re there. The camera doesn’t lie - and neither does the written estimate.
Our DuraFlex Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers, asks for your cap or crown symptoms, and books a Level 2 inspection slot. You’ll get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. We run the camera down the flue, photograph the crown from the roof and the firebox side, and document cap model numbers where visible. Corrine Halstead trained our Fort Worth crews to log DuraFlex part markings specifically - OEM vs. aftermarket matters for warranty tracking.
- 3
Written estimate on site. Before any tool comes out, you get a written scope, written price, and written warranty. Clause 1 of the Haven Standard: have it in writing. If you have a competitor’s written quote, we’ll give you a free second opinion.
- 4
Parts confirmation and repair. We source DuraFlex OEM, quality aftermarket through our Haven buying network, or compatible HeatShield or Gelco components when they better fit your system and budget. No surprises.
- 5
Post-repair camera verification and photo record. We re-scan the flue, photograph the completed cap or crown from multiple angles, and add everything to your documented record. Clause 4 of the Haven Standard requires this - we’ve done it on every job since 2009.
- 6
Cleanup, payment, and 365-Day Done Right Promise activation. If it’s not done right, we make it right. The promise is stamped on your invoice.

AfterWhat DuraFlex Chimney Cap & Crown Costs in Fort Worth

These are Fort Worth market ranges based on our 38,000+ jobs since 2009. Your exact price depends on what the camera shows and what you choose to do about it. We don’t quote over the phone for cap and crown work - the crown condition under an existing cap is too variable to guess. Call (682) 499-2712 for a free estimate - we’ll have a written price in your hands before any work starts.
Why Fort Worth Homeowners Call Level Two Chimney Fort Worth for DuraFlex Work

We’ve been running camera-down inspections in Fort Worth since 2009, back when most companies here were still using a flashlight and a mirror. That archive practice became Clause 4 of the Haven Standard. Our techs are background-checked, uniformed, and assigned by name - you’ll know who’s coming. We stock DuraFlex, HeatShield, and Gelco components through our Haven buying network, so we’re not pushing one brand because it’s all we carry. And we’re independently owned and operated, not a franchise, which means Corrine Halstead answers for every job personally. The 365-Day Done Right Promise isn’t a slogan - it’s stamped on your invoice. If something’s not right, we make it right.
FAQs
No. As an independent DuraFlex service provider, we use OEM-spec or compatible parts and document the work with photos. DuraFlex warranties cover manufacturing defects, not installation by independent technicians. We keep part serial numbers and installation photos in your record in case you ever need to file a claim.
Most single-flue replacements take 90 minutes to two hours once we’re on site, including the post-repair camera scan. Multi-flue DSA units run two to three hours. We’ll give you a time estimate in your written scope before we start.
Usually yes. We measure flue diameter, count flues, note roof pitch and clearance requirements, and cross-reference against our Haven buying network inventory. If an exact DuraFlex match isn’t available, we’ll quote an equivalent HeatShield or Gelco unit with the same or better specs, never a downgrade.
Hairline cracks without spalling or water staining often qualify for coating if the crown is otherwise sound. We verify with a moisture meter and camera inspection of the flue interior. If water’s already migrating through, we’ll show you the evidence and quote rebuild. You’re not pressured either way - the photos speak for themselves.
We book based on season and roof safety, not false urgency. In Fort Worth’s pre-burning-season rush (September through November), lead times stretch to 10-14 days. Off-season, we often have availability within a week. Call (682) 499-2712 for current scheduling - estimates are always free.
