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 Liner & Rebuild in Rockville: What to Know First
We’re an independent Olympia Chimney service provider in Rockville, and we handle stainless steel liner installation, liner replacement, partial rebuilds, and full chimney rebuilds for Olympia Chimney systems. Most Rockville jobs take one to two days on site, and you’ll get a written price before any work starts, not a phone estimate that changes when the tech arrives. If you own an Olympia Chimney flue liner that’s showing its age or failed an inspection, call (571) 376-7052 and we’ll put eyes on it with a camera, not a flashlight.
This page is for Rockville homeowners who already know they have an Olympia Chimney product and need the truth about whether it can be repaired or needs to come out. We’ll cover the failure patterns we see in Olympia liners across Rockville, what replacement actually costs, and how we document every step so you’re never guessing.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney makes solid products, but every liner brand has its weaknesses, and Rockville’s climate finds them. Here’s what we see most often on Olympia systems in this area:
- Ventis premium stainless liner seam separation at the collar. The Ventis line is common in Rockville homes built since 2010. The failure we see most is separation at the appliance adapter collar where the liner meets the stove or insert. The cause is almost always thermal cycling, hot flue gases against the cold air outside the chase. Rockville winters push that temperature swing hard. We fix it by pulling the adapter, checking the liner for warping, and reseating with a fresh connector and proper clearance, not by caulking it and hoping.
- Flexible liner kinking in narrow flues. Older Rockville colonials, especially the brick ones near King Farm, have flues that run narrow and offset. Olympia’s flexible liner is good, but a kinked liner creates a creosote trap and a draft problem. We see kinks at the smoke chamber transition most often. The fix is either straightening and re-supporting the liner or replacing the section if the kink has crushed the corrugation.
- Creosote glazing in Olympia liners serving wood stoves. We get called to Rockville homes where the Olympia liner was installed with a wood stove and never swept on a schedule. The result is Class III creosote, which is the glazed, tar-like form that resists brushing. In an Olympia liner it clings hard to the stainless corrugation. We run a chemical treatment followed by a rotary whip, and if the liner is too far gone or cracked, we replace it rather than send you into another season with a fire hazard.
- Rust-through at the chase top plate on older Olympia installations. The liner itself may be fine while the top plate and cap are rotted. In Rockville we get enough rain and freeze-thaw cycles that any gap in the chase cover lets water track down the liner and pool at the first offset. We inspect the whole chase, not just the flue, because a rusted top plate is why a “new” liner fails in three years.
- Improper clearance to combustibles in the chase. Some Olympia installations in Rockville were done by general contractors who didn’t maintain the required clearance between the liner and the chase framing. We find charred framing when we open these chases. This is a rebuild job, not a liner swap. We pull the chase, correct the clearances, and reinstall to code with documentation.

Our Olympia Chimney Chimney Liner & Rebuild Process

Every Olympia Chimney job in Rockville follows the same disciplined sequence. The camera doesn’t guess. Neither do we.
- 1
Book the inspection. You call (571) 376-7052, talk to a person, and get a window. A named technician is assigned, background-checked, and you get a text when they’re rolling.
- 2
Camera scan, documented. We run a Level 2 inspection, NFPA 211 style. The camera goes down the flue. You see the footage. We photograph everything and note the liner condition, crown integrity, and creosote class in plain terms.
- 3
Written scope and written price. Before anyone touches a tool, you get a written quote that spells out exactly what we found, exactly what we’ll do, and exactly what it costs. No verbal caveats, no “we’ll see what we find.”
- 4
Parts decision. If an Olympia liner is still under warranty, we use OEM parts to keep that warranty alive. If it’s out of warranty, we’ll show you the aftermarket options from DuraFlex, HeatShield, or Gelco and explain the differences honestly. Some of those aftermarket liners outperform the original.
- 5
Repair or rebuild. We pull the old liner if it’s dead, install the new one, rebuild the crown if needed, and correct any clearance or top plate issues as we go.
- 6
Test, document, hand over. We fire-test the system, run a final camera scan, and give you a photo record plus a written warranty. Clause 4 of the Haven Standard requires that photo record on every job, and it’s been that way since 2009.

AfterWhat Olympia Chimney Chimney Liner & Rebuild Costs in Rockville
Here’s the honest pricing picture for Olympia Chimney work in Rockville, based on what we actually quote:
- Stainless steel liner replacement (single flue, standard Rockville home): $2,200 to $4,500 depending on flue height, chase access, and whether we need a scaffold or just roof ladder work.
- Flexible liner swap (wood stove or insert, existing chase): $1,800 to $3,200. The lower end assumes a straight flue with no offset problems.
- Partial rebuild (crown, top plate, top section of liner): $3,500 to $6,000. Water damage usually means the top two feet of the system is compromised.
- Full chimney rebuild from the roofline up: $8,000 to $15,000. This is a real rebuild, new brick or blockwork, new liner, new crown, new cap. Rockville brick matching adds cost, and we’ll tell you if a full rebuild is actually necessary or if a partial fix buys another decade.
What moves the price is access, flue height, and whether the chase framing is involved. If you want an exact number, call (571) 376-7052 for a free estimate. We’ll put the price in writing before anyone starts.
Why Rockville Homeowners Call Level Two Chimney Rockville for Olympia Chimney Work

We’re not the oldest chimney company in Rockville, and we’re not the cheapest.

And if you’ve got a written estimate from another shop, bring it. We’ll give you a free second opinion.
FAQs
Olympia Chimney warranties vary by product line and installation date, and as an independent provider we can’t speak for the manufacturer. What we can tell you is this: if your liner is still under warranty, we use Olympia OEM parts and document the installation with photos, which is what any warranty claim will require. If it’s out of warranty, we’ll recommend the best liner for your setup, and sometimes that’s a DuraFlex or HeatShield product. Call (571) 376-7052 and we’ll check the details on your specific system.
In most Rockville homes, the liner can be replaced without rebuilding the whole chimney. A full rebuild is only necessary when the masonry itself is spalling, which means the brick face is flaking off, or when the chase framing has been compromised by water or fire. We’ll show you the camera footage before we recommend one or the other. If we recommend a rebuild, you’ll see exactly why on the screen.
Most liner replacements in Rockville are scheduled within one to two weeks, and the work itself takes one to two days on site. If you’re looking at a full rebuild, schedule for a longer window and expect masonry work. Call (571) 376-7052 and we’ll give you a real date, not a vague “soon.”
A compromised liner is the difference between a chimney that vents smoke outside and one that leaks carbon monoxide into the house or sparks into the chase. In Rockville, with our cold snaps and wet winters, a cracked liner also lets water into the masonry, which means freeze-thaw damage accelerates the bill. If your liner needs work, one more season usually costs more, not less. Get it looked at now.
We don’t price-match, but we’ll give you a free second opinion on any written estimate. Bring us the quote, and we’ll tell you if the scope is right, if anything’s missing, and what we’d charge for the same work. You’ll get our price in writing too. Call (571) 376-7052 to set that up.
