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 Damper Repair: The Denver Owner’s Guide
Olympia Chimney damper repair in Denver typically runs $340-$580 installed, depending on whether the throat plate, frame, or full assembly needs replacement. We stock common Olympia Chimney damper configurations on our trucks and can usually match your model same-day. Most Denver homeowners discover the problem when smoke rolls back into the living room on the first cold night, or when they spot daylight through a damper that won’t fully close.
Corrine Halstead and our crew have handled Olympia Chimney dampers in everything from 1920s bungalows in Congress Park to new builds in Stapleton. The camera doesn’t guess. Neither do we.
Which Olympia Chimney Models This Applies To
Olympia Chimney produces several damper series, and matching the right repair part matters more than with some other brands because their throat assemblies use proprietary frame widths. The most common we see in Denver are the OD series (OD-6 through OD-13, correlating to flue diameters from 6 to 13 inches), the ODL locking-damper line for exterior masonry chimneys, and the older ODP pivot-style plates found in homes built between 1995 and 2010.
To identify yours, look for the stamped model number on the damper frame’s left side, visible from the firebox with a flashlight. If the stamp is rusted over, measure the throat opening width and depth, plus the handle extension length. Olympia Chimney’s OD-8 and OD-10 frames are interchangeable with some Gelco and Famco equivalents we source through Haven’s buying network, but the ODL locking mechanism is OEM-only. We carry both on the truck. Level Two Chimney Denver is an independent service provider, not affiliated with Olympia Chimney.
Signs Your Olympia Chimney Damper Repair Is Failing

- Smoke backdraft on startup. The damper plate isn’t seating fully open, usually because the pivot pin has corroded or the frame has warped from heat cycling. In Denver’s dry climate, thermal expansion stress on metal happens fast, especially if the fireplace sees intermittent use.
- Daylight visible from the firebox when closed. The plate seal has degraded or the frame has dropped out of square. Even a 3/16-inch gap pulls conditioned air up the flue year-round, which you’ll notice on Xcel bills.
- Handle spins freely or jams halfway. The linkage between handle and plate has stripped, or rust has seized the worm gear. Olympia Chimney’s older ODP handles use a brass insert that strips under torque if the plate is already stuck.
- Rust flakes or metal debris in the firebox. The throat plate is spalling, not just surface-rusting. Once pitting reaches 1/8-inch depth, the plate won’t seal and replacement is the only fix.
- Animals or debris in the flue. A damper that doesn’t fully close is an open door. We’ve pulled bird nests and last autumn’s cottonwood fluff from Olympia Chimney throats in Park Hill and Wash Park where the plate had been stuck open for two seasons.

| Service | Price Range |
|---|---|
| Olympia Chimney damper plate replacement (OD series) | $340-$420 |
| Full throat assembly with frame (ODL or OD with warped frame) | $480-$580 |

What drives the range: accessibility (some throats sit 18 inches back; others need smoke chamber work to reach), whether the frame anchors have pulled from the masonry, and if we find secondary issues during the camera pass. Every quote is written before work starts, per Haven Standard Clause 1. The 365-Day Done Right Promise covers the installation. Materials come through Haven’s buying network, sourced from Olympia Chimney, Gelco, and Famco specifically to keep customer prices honest.
DIY or Call Us?

There’s a safe middle ground here. You can verify the model stamp, measure the throat, and confirm whether the handle turns freely without climbing into the firebox. What you shouldn’t do: reach past the throat to manipulate a stuck plate, or attempt to remove the frame assembly yourself. The frame is anchored into masonry above the smoke shelf, and the leverage required to free corroded bolts risks cracking the lintel or dropping debris into the flue.
We’ve also seen homeowners force a handle and strip the brass insert, turning a $260 linkage repair into a $580 full assembly. If you’re unsure what you’re looking at, call (720) 674-7312. We’ll text you a photo guide to identify your model, or book a camera inspection so you see exactly what needs doing before any price is discussed.
FAQs
In Denver’s low-humidity, high-UV climate, expect 12-18 years for an OD series plate if the fireplace burns weekly during season. Occasional use stretches that; frequent over-firing shortens it. The freeze-thaw cycles in unlined exterior flues accelerate frame corrosion. Call (720) 674-7312 for an exact quote - estimates are free.
Sometimes. A seized handle or stripped linkage can often be rebuilt. But once the plate is pitted, warped, or cracked, replacement is the only code-compliant fix. We won’t recommend replacement without camera evidence you can see yourself. Call (720) 674-7312 for an exact quote - estimates are free.
Most Olympia Chimney damper replacements run 90 minutes to 2.5 hours from ladder set to photo record delivery. Deep-set throats or lintel repair add time. We assign a named technician, send a text when they’re en route, and deliver your written scope, written price, and documented photo record before anyone leaves. Call (720) 674-7312 for an exact quote - estimates are free.
We carry OD-6 through OD-13 plates, ODL locking assemblies, and common handle/linkage kits on every truck. Oddball sizes or discontinued ODP pivot plates we pull from Haven’s same-day supplier network. If we don’t have it, we know where to get it without marking up the part. Call (720) 674-7312 for an exact quote - estimates are free.
