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 has been in the flue and venting business since the 1970s, and their stainless steel liner kits and rigid chimney systems show up regularly in Gaithersburg homes built or updated between 1990 and 2015. We work on their products as an independent Olympia Chimney service provider, which means we’re not bound by factory warranty-limitation shortcuts. When something fails, we repair to the condition that actually solves the problem, not the condition the manufacturer’s reimbursement schedule prefers. Here are the failure patterns we see most often on Olympia Chimney liners in this area:
- Corrosion at the tee snout and cap on Olympia Ventinox 316Ti flexible liners. The Ventinox line is solid product, but the tee connection at the base of the flue takes the brunt of acidic condensation from gas appliances, especially in Gaithersburg’s humid summers. We regularly see pinhole rust right where the tee meets the liner body. The fix is almost always a new tee assembly and a short liner section, not a full reline. Around $400 to $900 with labor.
- Creosote glazing inside Olympia rigid stainless chimney sections on wood stoves. Gaithersburg’s winter temperature swings mean hot fires followed by cold shutdowns, and that cycle produces Class III creosote, the shiny, tar-like glaze that resists brushing and eventually fuels chimney fires. We see this most on Olympia’s double-wall connector pipe where it enters the ceiling support box. Fix involves removal, chemical treatment, and sometimes section replacement if the stainless has warped from a previous chimney fire.
- Failed factory-welded cap seams on older Olympia stainless chase covers. The sheet metal caps on Olympia factory-built chases have welded corners that fatigue over time. Water gets in, then runs down the outside of the liner and collects at the firestop. The symptom is a rust ring on the ceiling below the chase. We replace the chase cover with a heavier-gauge stainless unit with a welded drip edge, and we re-insulate the liner chase while we’re in there.
- Collapsed or crushed flexible liner sections behind masonry offsets. When a Gaithersburg chimney has an offset in the smoke chamber, amateur installs routinely kink the flexible liner at that bend. We see this on Olympia Flex 316 liners installed during quick flips or by general remodelers. The fix is a rigid-to-flex transition with an offset elbow, not just yanking the liner tighter. Camera footage should show the kink clearly before you authorize any work.
- Separated joints on Olympia snap-lock connector pipe from repeated thermal cycling. The snap-lock seam on Olympia’s single-wall connector pipe can loosen after years of expansion and contraction, especially on wood stoves that run hot. Loose seams leak combustion gases into the living space. We replace the affected sections and re-secure with mechanical fasteners, which meets code and stops the smell of smoke in the house.
Our Olympia Chimney Chimney Liner & Rebuild Process

- 1
Call and schedule. A live person answers 24/7. We assign a named technician and send a text when they’re on the way. No dispatch windows, no waiting around.
- 2
Camera inspection first. We run a Level 2 camera scan down the flue and through the smoke chamber. Corrine Halstead pulls the camera out before quoting anything. You watch the footage with us, live or after, and we point out exactly what we’re seeing in plain terms.
- 3
Written scope of work with hard numbers. Before any work begins, you get a written price, written scope, and written warranty. Clause 1 of the Haven Standard: have it in writing. No verbal wiggle room, no surprise line items.
- 4
Parts decision: OEM vs. quality aftermarket. If an Olympia-specific part is needed and we can source the exact replacement, we quote it. If an OEM part is unavailable or priced irrationally, we quote a compatible equivalent from DuraFlex or HeatShield and tell you why we’re recommending it. We never install a component we wouldn’t put in our own chimney.
- 5
Liner installation or rebuild. Flexible liner runs pull in through the top and terminate with a proper cap and flashing. Partial rebuilds involve removing spalled brick, where the face has popped off from water absorption, down to sound masonry and re-laying with matching mortar. Full rebuilds go down to the roofline or below and include a new crown with a proper drip edge.
- 6
Photo record and test. We document the finished job with photos and a short video walkthrough, run a draft test to confirm the flue pulls correctly, and hand you a written warranty. The whole record is yours to keep. Clause 4 of the Haven Standard: every job leaves with a documented photo record, no exceptions.

Why Gaithersburg Homeowners Call Level Two Chimney Gaithersburg for Olympia Chimney Work

We’ve cleaned and inspected more than 38,000 chimneys since 2009, and every one of those jobs had a written price before the work started and a documented record when it was done. That practice became Clause 4 of the Haven Standard. The camera doesn’t guess. Neither do we.
Our technicians are background-checked and uniformed, with license information on every page of our paperwork. They know Olympia Chimney’s product lines well enough to identify a Ventinox tee failure on sight, and they carry multi-brand backup inventory from DuraFlex, HeatShield, and Gelco so a parts shortage doesn’t stall your liner job. If a DuraFlex part is actually the better fit because the chimney has an unusual offset, we’ll say so and show you why. If the job isn’t done right, the 365-Day Done Right Promise means we make it right within a year. That’s stamped on every job, not just the big ones.
FAQs
In most cases, no. Olympia Chimney warranties typically cover manufacturing defects in their own components, and a compatible stainless liner from a reputable manufacturer like DuraFlex or HeatShield will not void warranty coverage on the parts that are still under an Olympia warranty. But if your chimney is still within an active Olympia warranty period and the liner itself failed, we recommend calling Olympia first to see whether they’ll cover the replacement. We can provide the camera footage and measurements you’ll need to make that claim. If warranty doesn’t cover it or you’re out of warranty, we’ll quote the fix in writing. Call (240) 220-9395 and we’ll walk you through your specific situation.
Common Olympia components like tee snouts, caps, and connector sections are usually available within 3 to 5 business days through our supplier network. Some less common Olympia rigid chimney sections can take 2 to 3 weeks. If a part is on backorder and you can’t wait, we’ll recommend a compatible equivalent from DuraFlex, HeatShield, or Gelco and show you the spec sheet before making the switch. Call (240) 220-9395 and we can check availability on your specific model while we’re on the phone.
If the liner is deteriorated but the surrounding brick and mortar are sound, a stainless liner replacement is the right call and costs a fraction of a rebuild. If the brick is spalling, the crown is cracked, and there’s moisture damage behind the liner, you may need a partial or full rebuild. We’ll tell you which applies based on camera footage you can see for yourself, not on a guess. Bring us a written competitor estimate and we’ll give you a free second opinion. Call (240) 220-9395.
A flue liner contains combustion gases and protects the surrounding masonry from heat and acidic condensation. When an Olympia liner fails, hot gases can reach combustible framing, and carbon monoxide can enter the home. The liner is not a cosmetic part. It’s the difference between a chimney that vents and a chimney that leaks into the house. If you’re not sure whether your liner is intact, schedule a camera inspection. Call (240) 220-9395 and we’ll put a camera down the flue and show you exactly what’s there.
We don’t handle financing in-house, but we can point you to local credit union options if a full rebuild stretches the budget. The rebate and incentive landscape changes often, so rather than list programs that may not apply in Gaithersburg, we’ll help you figure out what’s actually available when we give you the written estimate. Call (240) 220-9395 for the exact numbers on your chimney.
