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.
Olympia Chimney Chimney Cap Installation: The Denton Owner’s Guide
We stock and install Olympia Chimney-compatible chimney caps for Denton homeowners, with typical installed pricing running $285-$475 depending on flue size and whether your crown needs remediation first. Most replacements are completed in a single visit, and we carry the common Olympia Chimney cap sizes on our trucks for the Denton market. You’ll usually discover the cap has failed when water starts showing up on the firebox floor after a North Texas storm, or when you spot rust streaks running down the brick from a cap that’s lost its galvanizing.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures caps across several product lines, and matching the right cap to your flue matters more than most homeowners realize. The Olympia Chimney 13×13, 13×17, and 17×17 galvanized models are the units we see most frequently in Denton homes built between 1995 and 2015, particularly in developments south of Loop 288 where builder-grade installations were common. If your cap is still legible, the model stamp sits on the underside of the lid, visible from the roofline with a flashlight. When that stamp has corroded away, we measure the flue tile opening directly, not the existing cap, since a poorly fitted cap may have been replaced once already with the wrong size.
We source Olympia Chimney caps through Haven’s buying network alongside DuraFlex, HeatShield, and Gelco equivalents. For most Denton installations, we recommend sticking with Olympia Chimney’s 24-gauge galvanized or 304 stainless options rather than generic aftermarket caps, because the mounting flange geometry on Olympia Chimney units is slightly narrower than competitors like Famco or Copperfield. An aftermarket cap can be adapted, but the fit often requires additional caulk work that becomes a maintenance point. We stock both OEM Olympia Chimney caps and verified cross-references on our trucks, so we’re not upselling you to a brand name when a quality equivalent exists.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing

- Water pooling on the firebox floor after rain. The cap’s mesh screen or lid seam has separated, allowing direct water intrusion. In Denton’s spring storm pattern, a single compromised seam can funnel surprising volume down the flue.
- Rust streaks running down the exterior brick. Galvanized caps lose their protective coating after 8-12 years in North Texas sun and ozone exposure. Once the base metal oxidizes, the runoff stains masonry and accelerates mortar deterioration.
- Animals or nesting debris visible from below. A cap with damaged or missing mesh sides no longer excludes squirrels, raccoons, or the starlings that nest heavily in Denton’s mature neighborhoods near the Square.
- Downdraft smoke during winter burns. The cap’s lid may have warped or blown partially off, disrupting the designed airflow pattern. This is especially common after the straight-line wind events that hit Denton County each March and October.
- Visible gaps between cap and flue tile. The mounting flange has corroded or the original installer used inadequate fasteners. Gaps exceeding 3/8 inch allow ember escape and direct water entry.

|---|---|
| Olympia Chimney cap (galvanized), installed | $285-$345 |
| Olympia Chimney cap (304 stainless), installed | $365-$475 |

What drives the range: flue accessibility (steep roof pitch adds ladder time), crown condition beneath the old cap, and whether we need to transition from a single-flue to multi-flue cap configuration. Every quote is written before work starts, per Haven Standard Clause 1. The 365-Day Done Right Promise covers installation defects and material failure. We don’t charge separately for the camera inspection or the photo record, Clause 4 of the Haven Standard requires both on every job.
DIY or Call Us?

You can safely check whether your cap is loose or visibly damaged from the ground with binoculars, and you can verify water intrusion by inspecting the firebox after the next rain. Don’t climb the roof yourself. Chimney cap replacement requires working at height on a surface that may be slick from algae or moss, and the fasteners are often seized after years of heat cycling. More critically, a cap that’s been leaking may have hidden crown damage or flue tile spalling that a ground inspection won’t reveal. We find concealed damage in roughly 40 percent of Denton cap replacements, particularly in homes near Lewisville Lake where humidity accelerates deterioration. The camera doesn’t guess, and neither do I. Call (940) 373-6912 and we’ll show you what you’re actually dealing with before you spend money on a part that may not solve the whole problem.
FAQs
Galvanized caps typically last 8-12 years in North Texas before rust-through, while 304 stainless units often exceed 20 years. Denton’s combination of intense summer UV and occasional hail events shortens galvanized life compared to cooler climates. Call (940) 373-6912 for an exact quote on upgrading to stainless.
Minor mesh damage can sometimes be patched, but lid seam separation or flange corrosion means replacement. We’ve found that repaired caps tend to fail again within 18 months, so we don’t recommend it as a lasting solution. Call (940) 373-6912 and we’ll show you the camera footage so you can decide.
Most Olympia Chimney cap installations are completed in 45-90 minutes, assuming no crown or flue tile repair is needed. We schedule a two-hour window to allow for documentation and cleanup. Call (940) 373-6912 to book.
We carry the common Denton sizes, 13×13 through 17×17, in both galvanized and stainless. Less common sizes or multi-flue configurations may require a next-day pull from our supplier network. Call (940) 373-6912 with your flue measurement and we’ll confirm availability.
