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 Cleaning & Sweep in Denver: What to Know First
We provide independent Olympia Chimney chimney cleaning and sweep services across Denver, from Capitol Hill brick walk-ups to the newer builds in Stapleton and Highlands Ranch. Most Olympia Chimney systems we service in Denver get a Level 2 camera inspection and sweep completed within one to two weeks of booking, with a written price delivered before any work starts. We’re not here to sell you a liner you don’t need; we’re here to show you what the camera found and let you decide.
This page is for Denver homeowners who installed an Olympia Chimney liner, cap, or component between 2015 and 2025 and need annual maintenance, suspect a blockage, or were told by another company that the system needs replacement. Corrine Halstead and our crew have cleaned and inspected Olympia Chimney products in Denver since 2009. Call (720) 674-7312 for a free estimate.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti stainless liners in older Denver flues: The 316Ti alloy handles our freeze-thaw cycles well, but we’ve found the flex sections flatten where they pass through offset clay thimbles in pre-1950 Denver homes, especially in Baker and Berkeley. The flattened segment traps Class III glazed creosote because the reduced diameter drops flue gas temperature below the dew point. We remove the liner section, re-ovalize or replace the flex, and document the before-and-after draft reading under Haven Standard Clause 4.
- Olympia Chimney Gelco-style caps with mesh sides: These cap-and-screen assemblies work until Denver’s cottonwood fluff and red elm samara pack the mesh in May and June. Homeowners in Park Hill and Montclair call us thinking they have a downdraft problem; what they have is a 60% blocked screen raising CO risk. We pull the cap, clean the mesh with a rotary brush, and check the spark arrestor integrity. If the screen is fatigued, we source replacement mesh through our Haven buying network rather than forcing a full cap replacement.
- Olympia Chimney smooth-wall rigid liners in high-efficiency gas inserts: The smooth interior is designed to shed condensate, but in Denver’s dry winter air paired with short burn cycles, we’ve seen acidic condensate pool in low spots rather than evaporate. This shows up as pinhole corrosion at the collar joint in 6-8 year old installs. We camera-locate the low spot, re-pitch or add a condensate drain per manufacturer guidance, and flag it in your documented record for next year’s sweep.
- Olympia Chimney oval-to-round adapters in masonry fireplaces: These adapters save space in shallow Denver hearths, but the weld seam faces the masonry and collects soot where the homeowner can’t see it. During a Level 2 inspection we rotate the camera to catch the seam face; if the weld shows heat discoloration or cracking, we replace with a seamless DuraFlex equivalent from our multi-brand inventory and note the OEM part number for your warranty file.
- Olympia Chimney top-sealing dampers integrated with their cap systems: The cable and spring assembly seizes when Denver’s road salt dust works into the mechanism over two or three winters. A stuck open damper wastes heat; stuck closed risks smoke spillage. We disassemble the damper, clean the cable run with a solvent that won’t degrade the nylon sheath, and test the seal with a smoke pencil. If the cast-aluminum frame is cracked, we quote an exact replacement part number before ordering.
Our Olympia Chimney Chimney Cleaning & Sweep Process

- 1
Booking and scope lock: You call (720) 674-7312, a live person answers, and we schedule. We ask the appliance type, fuel, last service date, and whether you have an Olympia Chimney component installed. You get a two-hour arrival window and a text when your tech is en route.
- 2
Level 2 inspection with camera: We run a chimney camera the full flue length, per NFPA 211 Level 2. For Olympia Chimney liners, we pay particular attention to flex-to-rigid transitions and collar joints where the brand’s documentation flags potential wear points. The camera doesn’t guess. Neither do we.
- 3
Written price before work: Haven Standard Clause 1: we deliver a written scope, written price, and written warranty before any tool touches your system. If the camera shows only a standard sweep is needed, that’s what we quote. If an Olympia Chimney part needs replacement, we note whether we’re sourcing OEM or a quality aftermarket equivalent and why.
- 4
Sweep and component service: We use rotary poly or wire brushes sized to your Olympia Chimney liner diameter, never a one-size-fits-all approach that can score stainless or leave glazed creosote. Caps come off for mesh cleaning; dampers get exercised and lubricated.
- 5
Testing and documentation: We run a final draft test and visual seal check. You receive a photo record, camera footage summary, and written completion report under Haven Standard Clause 4. Every job since 2009 has been documented this way.
- 6
365-Day Done Right Promise: If something we swept or inspected needs re-addressing within a year, we make it right. No argument, no invoice.

FAQs
No. As an independent Olympia Chimney service provider, we follow manufacturer maintenance specifications for cleaning intervals, brush types, and inspection protocols. Warranty coverage for defects in materials or workmanship remains intact; damage caused by improper service is what voids coverage, and our documented photo record protects you if that question ever arises. Call (720) 674-7312 if you need warranty documentation for a claim.
Yes. We stock common Olympia Chimney caps, liners, and dampers through our Haven buying network, and we source less common sizes with typical lead times of three to five business days. For urgent safety issues, we can often install a compatible DuraFlex or Gelco equivalent same-visit and order the exact Olympia Chimney part for permanent installation. Call (720) 674-7312 to confirm availability for your model.
The camera decides. A sweep addresses creosote and soot buildup; repair addresses structural damage like cracks, seam separation, or corrosion pitting. During your Level 2 inspection, we show you the footage and explain which category your finding falls into. If the liner is sound but dirty, we sweep and schedule next year. If there’s a breach, we quote repair with exact measurements and part numbers. Call (720) 674-7312 to book the inspection that answers this.
NFPA 211 recommends annual inspection for all chimney systems; sweeping frequency depends on use and fuel. In Denver, where altitude reduces combustion efficiency and cold starts are common, wood-burning Olympia Chimney liners often need annual sweeping. Gas systems with Olympia Chimney rigid liners may go two years between sweeps if condensate drains are clear. We set your next interval based on what the camera finds, not a calendar default. Call (720) 674-7312 to schedule.
Class I and II creosote hardens into glazed Class III, which standard brushes won’t remove and which ignites at lower temperatures. Blocked caps or dampers raise carbon monoxide risk, especially in tightly sealed modern Denver homes. The repair cost rises too: a $289 sweep becomes a $1,800+ liner replacement when corrosion or chimney fire damage progresses. We don’t scare-sell; we show you the camera footage and let you decide what timeline works. Call (720) 674-7312 for a free estimate.
