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 Frisco Owner’s Guide
Olympia Chimney chimney cap installation in Frisco typically runs $280-$520 for standard single-flue models, including the cap, collar, fasteners, and labor with a written warranty. We stock Olympia Chimney-compatible caps in common sizes and can usually match your model same-day from our Frisco warehouse. Most homeowners discover the problem after a storm blows the cap off, or when water stains appear on the firebox ceiling during our wet spring months.
Corrine Halstead and our crew have replaced Olympia Chimney caps across Frisco, including several homes in Starwood where the larger hearths and exposed ridge lines catch more wind than the newer subdivisions closer to the tollway. The camera doesn’t guess. Neither do we. We document the flue condition before quoting, because a cap is only as good as the crown it sits on.
Which Olympia Chimney Models This Applies To
Olympia Chimney caps are not one-size-fits-all. The brand produces three main series for residential use: the standard galvanized line (model prefix OCS), the stainless steel pro-grade line (OCP), and the copper architectural line (OCC). The OCS caps fit flue tiles measuring 8″×8″ through 13″×13″ square, and 8″-12″ round. The OCP and OCC series add an adjustable collar for oval or rectangular flues up to 19″×11″.
Here’s the compatibility gotcha we run into most in Frisco: Olympia Chimney changed its fastener spacing in 2019. Pre-2019 caps use four bolts at 90 degrees. Post-2019 caps use six bolts at 60 degrees. If you’re ordering from a photo, you’ll get the wrong base plate. We measure bolt pattern, flue tile OD, and crown overhang before pulling stock.
We source through Haven’s buying network from Olympia Chimney, Gelco, and Famco. For most Frisco homes, we recommend the Olympia Chimney OCP stainless line. It carries a lifetime warranty against corrosion, which matters here because our clay-heavy soil creates more ground-level moisture migration than Dallas County homes see. The galvanized OCS line costs less upfront but shows surface rust in 4-6 years in Frisco conditions. Copper OCC is available for historic district or HOA-mandated installations.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing

- Visible rust streaks down the flue tile. Stainless steel shouldn’t rust. If you’re seeing orange runoff, you likely have a galvanized cap marketed as “stainless look,” or the cap was swapped for a lower-grade unit during a previous sale. The rust is cosmetic at first, then structural as the mesh screen corrodes through.
- Water in the firebox after rain, even with the damper closed. This usually means the cap’s lid has separated from its skirt, or the storm collar was never sealed with high-temp silicone. In Frisco, our March and October wind events lift poorly fastened lids. The water pools on the smoke shelf and breeds odor.
- Birds or squirrels audible in the flue. Olympia Chimney caps include 5/8″ mesh screening to block wildlife. If an animal gets in, the mesh is torn, missing, or the wrong cap was installed with larger gaps. We’ve found tennis balls and leaf wads stuffed up there by previous owners who treated the symptom instead of the screen.
- The cap is visibly tilted or shifted from vertical. Wind shear along the Preston Ridge does this. A tilted cap channels water toward the low side instead of shedding it evenly. We check plumb with a level; anything past 5 degrees off vertical needs reseating or replacement.
- Spalling brick or deteriorated mortar on the chimney crown directly below the cap edge. The cap’s drip edge should extend 2″ past the crown perimeter. If it doesn’t, water runs down the flue tile and freezes on the crown. Frisco sees 15-20 freeze-thaw cycles most winters. That cycling pops surface mortar in two to three seasons.

| Component | Price Range |
|---|---|
| Olympia Chimney OCS galvanized cap, installed | $280-$340 |
| Olympia Chimney OCP stainless cap, installed | $380-$460 |
| Olympia Chimney OCC copper cap, installed | $480-$520 |

What drives the range: height of roof access, condition of the existing crown, and whether the flue tile protrudes the standard 2″-4″ or needs extension. Every quote in Frisco includes the cap, all fasteners, high-temp sealant, a camera scan of the flue interior, and a written warranty under our 365-Day Done Right Promise. Clause 1 of the Haven Standard requires the written price before work starts; Clause 4 requires the photo record we deliver after.
We don’t pad estimates with crown work you don’t need. If the crown is sound, we say so and show you the camera footage. If it’s cracked, we sketch the damage in Corrine’s field notebook and quote resurfacing separately. No package deals, no surprises.
DIY or Call Us?

What you can safely check from the ground: confirm the cap is present, level, and not visibly damaged. Use binoculars. Note the model stamp if readable. That’s it.
What goes wrong with DIY installation: most Frisco roofs are 6/12 pitch or steeper, and chimney stacks sit at the ridge where wind exposure is highest. The work requires ladder positioning on uneven ridge lines, working with both hands at height, and torquing fasteners without dropping hardware down the flue. More critically, a poorly seated cap directs water into gaps you can’t see from above. We’ve been called to fix DIY installs where the homeowner used deck screws instead of the stainless through-bolts, or skipped the storm collar entirely because it wasn’t obvious in the box.

FAQs
The OCP stainless line lasts 20+ years in Frisco’s climate; we’ve seen OCS galvanized caps fail in 4-6 years from soil-moisture corrosion. Copper OCC develops its patina in 3-5 years but holds structural integrity indefinitely. Call (940) 290-7230 for an exact quote on replacement - estimates are free.
Mesh screens can sometimes be rewired if the tear is small and the frame is solid. Separated lids, cracked bases, or corroded fasteners mean replacement. We show you the camera footage and explain which category yours falls into before quoting. Call (940) 290-7230 for an exact quote - estimates are free.
Standard replacement on a sound crown takes 45-90 minutes. If crown repair or flue extension is needed, plan on 2-3 hours. We book morning slots in Frisco to avoid afternoon wind. Call (940) 290-7230 to check availability - estimates are free.
We stock OCS and OCP caps in 8″×8″, 8″×12″, 12″×12″, and 13″×13″ square, plus 8″ and 10″ round at our Frisco warehouse. Odd sizes or copper OCC ship in 2-3 business days through Haven’s buying network. Call (940) 290-7230 and we’ll confirm fitment against your model number before you book - estimates are free.
