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.

How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney Ventis Series inserts: pilot assembly carbon fouling. The Ventis direct-vent inserts sold heavily in the 2018-2022 window use a SIT 820 Nova millivolt pilot that sits low in the firebox. In Denton’s clay-heavy soils, minor foundation shift stresses the flex line, the pilot orifice ingests dust during our windy spring months, and the flame signal drops below 325 mV. We pull the burner tray, clean the pilot hood with a #79 drill bit (never a wire brush - it widens the orifice), and replace the thermopile if voltage reads under 250 mV under load. The fix holds; we’ve tracked 340+ Ventis pilot services in Denton since 2019.
- Olympia Chimney wood-burning firebox: refractory panel cracking at the throat. The Olympia Chimney Heritage series uses a three-piece refractory system with a narrow throat opening. When homeowners in Denton’s older neighborhoods near the historic square burn unseasoned post oak - common here because it’s cheap and local - the thermal cycling cracks the center panel at the smoke chamber junction. We measure the crack width: under 1/8 inch, we seal with HeatShield Cerfractory foam; over 1/8 inch or any spalling, we source a factory panel or fabricate a steel overlay if Olympia’s lead time stretches past burning season.
- Olympia Chimney gas log sets: burner pan rust-through. The stainless burner pans on Olympia’s Vented Natural Gas sets (model prefix OVG-) are 430-grade, not 304. Denton’s humidity swings, especially in homes near Lewisville Lake with crawl-space air infiltration, accelerate oxidation at the burner ports. We see this at year 6-8, not the 15 the manual suggests. We replace with a DuraFlex coated pan or source OEM if the customer wants to maintain the original warranty paperwork; either way, we pressure-test at 14″ w.c. and document the reading.
- Olympia Chimney top-sealing dampers: cable fray at the chimney crown. The Lock-Top damper retrofit (Olympia part OL-TLD series) uses a 3/16″ aircraft cable that exits through a brass seal. Denton’s hail season beats the cap housing out of round, the cable chafes, and the damper hangs at half-mast. We replace the cable with a Gelco stainless aircraft cable, realign the cap, and seal the penetration with CrownSeal - not silicone, which UV-degrades in Texas sun inside 18 months.
- Olympia Chimney flex liner: mortar intrusion at offset joints. The Olympia Pro-Flex 316Ti liner, common in Denton fireplace insert retrofits, uses a compressed seam joint. When the original masonry chimney was built with a 30-degree offset to clear a second-floor joist - standard in 1970s Denton ranch builds - the flex drags mortar nubs during pull-through. The seam opens, creosote leaks into the chase, and you smell it before you see it. We camera the full length, mark the offset, and either sleeve with a DuraFlex smooth-wall section at the bend or recommend a partial rebuild if the offset exceeds 45 degrees.
Our Olympia Chimney Fireplace Services Process

- 1
Call and schedule. A live person answers, checks Olympia Chimney part availability against our Denton warehouse stock, and books a 2-hour arrival window. You get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. We run a chimney camera the full flue length, record the footage, and note the model and serial number of your Olympia Chimney component. Corrine Halstead’s standard: the camera doesn’t guess - and neither do I.
- 3
Written diagnosis and price. Before any repair, you receive a written scope, a written price, and a written warranty under Haven Standard Clause 1. No verbal quotes. No “let’s see what we find.”
- 4
Parts decision: OEM or quality aftermarket. We stock DuraFlex, HeatShield, and Gelco equivalents for common Olympia Chimney wear items. If your unit is under manufacturer warranty, we flag which parts must be OEM to preserve coverage and which can safely substitute.
- 5
Repair, test, and document. We complete the work, pressure-test gas components or draft-test wood systems, and upload the photo record to your job file under Haven Standard Clause 4. You get the invoice and the documentation simultaneously.
- 6
365-Day Done Right Promise. If the fix fails, we return and make it right. Stamped on every job.

FAQs
No, routine service by a qualified independent technician does not void the warranty, provided OEM parts are used for any covered-component repair. We flag which parts must be Olympia-original to preserve coverage and which wear items can safely use quality aftermarket equivalents like DuraFlex or HeatShield. Call (940) 373-6912 and we’ll review your warranty status before booking.
Common wear items - thermopiles, pilot assemblies, refractory panels for the Heritage series - ship to our Denton warehouse in 3-5 business days. Specialty or discontinued items may take 10-14 days. We stock DuraFlex, HeatShield, and Gelco cross-compatible parts for urgent repairs, and we’ll tell you before ordering whether an aftermarket substitute is appropriate for your unit.
Replace when the firebox or heat exchanger is cracked beyond safe repair, the unit is pre-2010 and parts are discontinued, or repair costs exceed 60% of a new insert installed. Repair when the issue is isolated to the gas train, damper, refractory panels, or liner - these are fixable at a fraction of replacement cost, and we’ll show you the camera footage so you can decide. Call (940) 373-6912 for a free estimate.
Gas units: annually, per NFPA 211, with a Level 2 camera inspection every three years. Wood-burning units: annually, without exception, because Denton’s post oak and mesquite produce Class II and III creosote that accelerates in the mild, humid winters. Skip a year and you’re gambling with a chimney fire or CO intrusion. We send reminder texts; ask when you book.
The risks are real and specific: a fouled pilot can leak raw gas before ignition, a cracked heat exchanger can vent CO into the living space, and a failed blower can overheat the firebox. These are not hypothetical - we find them on camera in Denton homes every month. The camera finds what you can’t smell or see. Call (940) 373-6912 for an exact quote - estimates are free.
