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 Hoffman Estates Owner’s Guide
Olympia Chimney chimney cap installation in Hoffman Estates typically runs $280-$520 installed, depending on flue diameter and whether your chase needs flashing work. We stock Olympia Chimney-compatible caps in 8″, 10″, and 13″ round sizes plus standard rectangular chase covers, and most replacements in Hoffman Estates are completed in under two hours. You’ll usually spot the problem after a windstorm when water hits the firebox, or when squirrels start using your flue as a highway.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures caps for their own stainless steel liner systems and for direct-vent gas inserts, but the critical detail is this: their caps are sized to the flue liner diameter, not the chimney crown dimensions. We’ve found Olympia Chimney caps on 6″ flexible liners in townhome clusters near Higgins Road, on 8″ rigid liners in 1990s builds off Golf Road, and on 10″ systems in larger homes near Hoffman Estates Road. The part number you’re looking for starts with “OLY-” followed by the diameter and termination type, stamped on the underside lip of the existing cap.
Here’s where owners get stuck. Olympia Chimney’s OEM caps use a twist-lock collar specific to their liner top fittings. A generic big-box cap will seat poorly and void any remaining liner warranty. We source Olympia Chimney caps through Haven’s buying network, or match with Gelco or Famco equivalents when the OEM lead time stretches past burning season. Corrine Halstead checks the liner manufacturer stamp on every job, because we’ve seen three “Olympia Chimney” calls this year where the liner was actually a DuraFlex system with an Olympia Chimney cap retrofitted by a previous owner.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing

- Rust streaks down the chimney face. Olympia Chimney caps use 304 stainless in standard grade, but the spot-welded seams at the hood corners are the first failure point in Hoffman Estates’ freeze-thaw cycle. Water gets behind the seam, freezes, and pushes the weld until it weeps orange down your brick.
- Water in the firebox after rain, but only from one side. This usually means the cap has shifted on its collar. Olympia Chimney’s twist-lock system loosens when the liner expands and contracts through winter; once the cap rotates even 15 degrees, the drip edge no longer clears the flue tile below.
- Bird or squirrel noise above the damper. The mesh screen on Olympia Chimney caps is 5/8″ weave, which stops most animals unless the screen has corroded through at the tension points. We replace three to four of these annually in Hoffman Estates, always in homes where the cap is past year twelve.
- Draft problems that started suddenly. A cap hood crushed by branch impact, or a liner that has slipped down inside the chase, changes the draw geometry. The cap is still there, but it’s no longer doing the job.
- Visible gaps between cap and crown. Olympia Chimney caps don’t seal to the crown, they seal to the liner. If you’re seeing crown gaps, the real problem is often liner settlement, and swapping the cap alone won’t fix it.

AfterReplacement Cost & What’s Included
| Component | Price Range (Hoffman Estates) |
|---|---|
| Olympia Chimney OEM cap, 6″-8″ round | $180-$260 |
| Olympia Chimney OEM cap, 10″-13″ round | $240-$340 |
| Chase cover / rectangular cap | $320-$480 |
| Labor, removal and installation | $140-$220 |
| Flashing seal or storm collar (if needed) | $60-$120 |
| Typical total installed | $280-$520 |
The range depends on three things we check during our camera inspection: whether the liner top fitting is still true (twisted fittings need replacement, not just the cap), whether the storm collar below the cap has cracked, and whether your chase cover needs resealing to the framing. We deliver a written price before work starts, Clause 1 of the Haven Standard, and every cap installation carries our 365-Day Done Right Promise. Materials come through Haven’s buying network, procured from Olympia Chimney, Gelco, or Famco depending on availability and your liner spec.
DIY or Call Us?

You can safely check two things from the ground: whether the cap is visibly shifted or missing, and whether water is entering after rain. Use binoculars. Don’t climb.
The actual replacement requires working at roof height on a potentially steep chase, handling a cap that may be wind-loaded or improperly seated, and resealing the storm collar without disturbing the liner termination. The liner itself is stainless steel but the top fitting is often galvanized, and cross-threading the twist-lock during reinstallation means a complete liner top rebuild. We’ve been called to Hoffman Estates homes where a DIY cap swap turned into a $1,400 liner repair because the collar was forced.
Camera first, price second, pen third - in that order every time. Call (331) 200-4445 and we’ll scope the flue, name the price, and show you the footage before you decide.
FAQs
Expect 12-18 years for the 304 stainless standard grade, or 20+ for 316L marine-grade if you upgraded at original install. The freeze-thaw cycle off the Fox River watershed accelerates seam fatigue, so we see Hoffman Estates caps retire closer to 14 years than 18. Call (331) 200-4445 for an exact condition check - estimates are free.
Mesh screens can be rewired and minor hood dents can be corrected, but once the twist-lock collar distorts or the seam welds crack, repair costs approach replacement without the warranty. We show you the specific failure on camera and price both options in writing before you choose. Call (331) 200-4445 for a free second opinion on any estimate.
Most Olympia Chimney cap replacements are 45-90 minutes on the roof, plus our standard NFPA 211 Level 2 camera inspection and photo documentation. We schedule a two-hour window and usually finish early. Call (331) 200-4445 to book.
We carry 8″, 10″, and 13″ round caps and standard rectangular chase covers daily. Specialty sizes or 316L grade ship overnight through Haven’s buying network. We confirm your exact spec by camera before ordering so nothing sits on your invoice that you didn’t approve. Call (331) 200-4445 to verify availability for your model.
