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.

AfterOlympia Chimney Chimney Cap & Crown in Dallas: What to Know First
We provide independent Olympia Chimney chimney cap and crown service across Dallas, typically completing standard cap replacements or crown repairs within one to two business days of your call. Every job starts with a camera-scan inspection, a written price you approve before any work begins, and a documented photo record when we’re done. If you own an Olympia Chimney product and need cap or crown work, call (972) 284-1392 for a free estimate.
This page is for Dallas homeowners who bought an Olympia Chimney cap, crown assembly, or multi-flue system between 2015 and 2025 and now need installation, replacement, or repair. Corrine Halstead and our crew have worked these units in neighborhoods from Lake Highlands to Preston Hollow, where Texas sun and sudden freeze cycles stress metal and masonry differently than up north. Camera goes in first. Everything else follows.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney Gelco-style single-flue caps (GVC series): The 304 stainless mesh on these units welds at the seam, not the frame, and Dallas hail from March through May dents the lid enough to crack that weld. Water pools in the depression, rusts the mesh from the inside out, and suddenly you’ve got a cap that looks intact but lets birds and rain straight into the flue. We remove the damaged lid, assess whether the base flange is still square, and either source an exact Olympia replacement or fit a Gelco aftermarket lid with a reinforced seam that holds up to North Texas hail better than the original spec.
- Olympia Chimney multi-flue caps (Olympia Outside Mount series):strong> These ship with a standard 10-inch skirt that works fine in snow-load zones but sits too low for Dallas roofs with 6/12 pitch or steeper. Wind-driven rain from our spring supercells blows straight up under that short skirt and soaks the crown underneath. We see this on homes in Lakewood and the M Streets where builders spec’d the cap to code minimum. Our fix is either a custom-fabricated 14-inch skirt extension or a full replacement with an Olympia-compatible multi-flue cap sized to the actual roof pitch and prevailing wind direction.
- Olympia Chimney crown coat systems (CrownSeal applications on Olympia-brand crowns): Olympia’s factory crown mix is Portland-based with a standard cure, which works until Dallas summer heat drives interior flue temps above 200°F for weeks straight. The thermal cycling opens hairline cracks that CrownSeal bridges for two, maybe three seasons, then the membrane delaminates in sheets. We strip the failed coating, re-profile the crown with proper slope and drip edge, and apply a HeatShield-compatible crown coat rated for sustained 300°F exposure. The photo record shows you the crack pattern before and the new profile after.
- Olympia Chimney chase pans (prefab chimney chase applications): The galvanized chase pans on Olympia prefab units rust at the corners first, always, because the factory fold leaves a micro-gap that traps condensation from our humid Gulf-front air. By the time you see a water stain on the ceiling below, the pan has been leaking for two winters. We replace with a copper or stainless chase pan, soldered at the corners, with a cricket diverter if the chase sits on the low side of a Dallas roof valley.
- Olympia Chimney wind-directional caps (Vacu-Stack and similar spinners): The bearing assembly on these caps seizes when creosote dust mixes with Texas red clay dust that blows up the flue during dry spells. The cap stops spinning, creates a static pressure zone, and actually draws smoke back down on certain wind angles. We disassemble the bearing, clean with solvent, and if the race is pitted, we replace with a sealed ceramic bearing from our Famco supply line that doesn’t grind itself to powder in dusty conditions.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers (972) 284-1392, 24 hours a day. We book your camera inspection, text you the technician’s name and photo, and send another text when they’re en route.
- 2
NFPA 211 Level 2 inspection. Our tech runs a camera down the flue, photographs the crown from the roof and the firebox looking up, and records mesh condition, lid integrity, and any water staining on the smoke chamber walls. You see what we see in real time.
- 3
Written scope and price. Before any tool touches your chimney, you get a written price, written scope, and written warranty under Haven Standard Clause 1. No exceptions. If you have a competitor’s written estimate, we’ll give you a free second opinion.
- 4
Parts decision. We stock Olympia Chimney-compatible caps and crowns through our Haven buying network. If your unit is under manufacturer’s warranty and requires OEM parts to keep that coverage, we source accordingly. If warranty is expired or the OEM part has a known defect, we’ll quote a quality aftermarket alternative from DuraFlex, HeatShield, or Gelco and explain the trade-off in writing.
- 5
Repair or replacement. We work to NFPA 211 standards, document each step with photos, and pressure-test or smoke-test the finished assembly depending on the job type.
- 6
Cleanup and record delivery. You receive a documented photo record of the completed work, same day, under Haven Standard Clause 4. The 365-Day Done Right Promise applies automatically. If it’s not done right, we make it right.

We source materials through the Haven buying network from Olympia Chimney, DuraFlex, HeatShield, Gelco, Famco, and Copperfield, which keeps our prices honest and our options open.

If it’s not done right, we make it right.
FAQs
Using an independent service provider does not automatically void your warranty, but installing non-OEM parts on a warrantied component can. We check your purchase date and serial number before quoting, and if warranty coverage still applies, we’ll source OEM parts or document in writing why an aftermarket alternative is the better choice. Call (972) 284-1392 and we’ll verify your warranty status before scheduling.
Expect 8 to 14 years for stainless units, 5 to 8 for galvanized, depending on roof pitch, tree cover, and whether you’re in a hail corridor like parts of Richardson or Garland. Our camera inspection shows you exactly where your cap is in that lifecycle. Estimates are free.
We can coat and preserve a crown with surface cracking and intact structural thickness, typically anything under 3/8-inch crack width with no spalling below the top layer. If the crown has lost its slope, developed through-cracks, or the masonry below is saturated, we recommend full rebuild and we’ll show you the camera evidence why. Nothing gets recommended without photos you can see.
We stock common Olympia Chimney cap sizes and compatible aftermarket alternatives through our Haven network. Specialty or discontinued items typically arrive within 3 to 5 business days. If your fireplace is unusable due to cap or crown failure, we’ll prioritize temporary weatherproofing while parts are in transit. Call (972) 284-1392 to check current stock.
Water intrusion through a failed cap or cracked crown deteriorates the flue liner, rusts the damper, and can damage interior framing and drywall. In Dallas, our hard freezes are brief but sharp, and water-saturated masonry spalls badly when it freezes. Carbon monoxide risk increases if the liner fails and combustion gases leak into wall cavities. We don’t scare-sell, but we do document what we find and explain what can wait versus what can’t. Call for a free camera inspection and written assessment.
