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.

AfterOlympia Chimney Chimney Liner & Rebuild in Rockville: What to Know First
Chimney liner and rebuild work on Olympia Chimney systems in Rockville typically runs between $1,900 and $6,500 depending on liner material, flue height, and whether we’re doing a partial or full rebuild. We complete most Olympia Chimney liner replacements in one day, with full rebuilds taking two to three days. This page covers what we see inside Olympia Chimney flues in Rockville homes, what it costs, and when the work can honestly wait. We’re an independent Olympia Chimney service provider, not a manufacturer affiliate. Call (240) 716-5865 and Wendell will give you the straight answer.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney makes solid products, but every liner and system has its weak points. Here’s what we actually find when we open up an Olympia Chimney flue in Rockville:
- Olympia Flex 316Ti liner seam separation. We see this most in Rockville homes built in the 1980s and early 1990s where liners were installed tight against masonry with no insulation wrap. The steel expands and contracts through Rockville’s freeze-thaw cycles and the seams start to pull. When we find it, we don’t patch. We pull the old liner and install a properly insulated replacement, usually with an Olympia or DuraFlex liner depending on the appliance.
- Cast-in-place Olympia liner spalling. Older Olympia cast liners poured in the 1970s crack at the corbels in two-story Rockville colonials. The mortar mix was too wet, and decades of condensation have turned the inside surface into something that looks like a dried creek bed. Partial rebuild is usually the fix here: we break out the damaged section and repour with a modern mix rated for your appliance.
- Olympia rigid liner joints loosening on oil-to-gas conversions. Rockville has a lot of mid-century homes that switched from oil to gas in the 1990s, and the converted systems often kept the old Olympia rigid liner. Gas exhaust runs cooler than oil, so condensation sits at the joints instead of evaporating. The joints loosen, and carbon monoxide finds the path of least resistance. We see this in Twinbrook and Hungerford regularly. These jobs almost always need a full liner replacement sized for the current appliance.
- Cracked Olympia chimney crowns wicking water into the liner cavity. The crown on an Olympia system takes a beating from Rockville summers and ice storms. Once the crown develops hairline cracks, water gets behind the liner and starts rusting it from the outside in. We rebuild the crown, replace the damaged liner section, and usually recommend a proper cap. It’s the difference between a $2,300 repair and a $6,000 full rebuild a year later.
- Flue tile collapse in Olympia masonry systems. We’ve pulled out flue tiles from Olympia masonry chimneys in Rockville that crumbled like drywall when we touched them. Twenty years of wet, acidic exhaust dissolves the mortar joints between tiles. Once the tiles shift, the flue can’t vent properly. This is when a stainless liner becomes the honest fix: you get a continuous, insulated liner that doesn’t depend on old tile to carry exhaust.
Our Olympia Chimney Chimney Liner & Rebuild Process
Here’s how a typical Olympia Chimney liner or rebuild job unfolds when you call Top Hat Chimney in Rockville:
- 1
The call. You talk to a live person. It may well be Wendell, and he’ll ask what you’re seeing: water stains, smell, loose brick, or just a bad inspection report from a home sale.
- 2
The camera inspection. Wendell or one of his crew runs a camera through the flue from top to bottom. You see the footage, and we give you the plain-English verdict: what’s actually wrong, what needs doing now, and what can wait.
- 3
The parts decision. We source Olympia OEM parts when they’re warranty-relevant or the best fit, and we’ll tell you plainly when a quality aftermarket liner like DuraFlex or HeatShield does the same job for less. No mystery parts, no padding the invoice.
- 4
The price, before tools. You get an upfront number before a single tool comes off the truck. That’s the number on the invoice. And every repair over $200 gets $40 off.
- 5
The work. We remove the old liner or damaged masonry, prep the flue, install and insulate the new liner or rebuild the damaged section, then test the draft with the appliance running. Cleanup happens before we leave.
- 6
The 90-Day Done Right Promise. Every job gets it in writing. If it’s not right, one call brings Wendell back at no additional cost.
What Olympia Chimney Chimney Liner & Rebuild Costs in Rockville
Honest numbers for common Olympia Chimney jobs in Rockville:
- Flexible stainless liner replacement (single flue): $1,900 to $3,400 installed, depending on flue height and whether insulation is required.
- Rigid stainless liner: $2,800 to $4,500. More labor, more precise fit, better for high-efficiency gas appliances.
- Partial rebuild (crown, top courses of brick, corbel repair): $2,200 to $5,000, depending on access and extent of masonry damage.
- Full chimney rebuild from the roofline up: $4,500 to $9,500. This is the big one. We only recommend it when the evidence on camera says it’s necessary.
- Liner repair without full replacement: $450 to $1,200 if we catch small joint separation or minor crown issues early.
What moves the price: flue height, roof pitch, liner diameter, and whether we need staging or a lift. Rockville homes with steep rooflines and three-story flues cost more than a ranch with easy access. Estimates are free. Call (240) 716-5865 and we’ll give you the number before any work begins.

FAQs
Installing a replacement liner does not automatically void an Olympia Chimney warranty, but it depends on the original installation date, the warranty terms, and whether the failure is a covered defect. As an independent Olympia Chimney service provider, we can’t process warranty claims on the manufacturer’s behalf, but we can document the failure with camera footage and a written report you can submit. Call (240) 716-5865 and we’ll walk you through what your system qualifies for.
Most single-flue Olympia Chimney liner replacements in Rockville are done in one day, assuming the existing flue doesn’t have hidden masonry damage. If we find spalling or crown issues once we open things up, the job may stretch to two days so masonry can cure properly. We’ll confirm a real arrival window and call you if it slips.
It depends on what the camera shows. Minor joint separation in an otherwise sound liner can often be repaired. Through-wall corrosion, multiple failed seams, or spalling means replacement is the honest call. We never recommend replacement without showing you the footage first. Free second opinion on any written estimate from another company.
We use Olympia OEM parts when they’re the right fit for the warranty or the system, and we’ll tell you plainly when a quality aftermarket liner like DuraFlex or HeatShield does the same job for less money. You decide with full information. No mystery markups, no parts you never approved.
Your flue doesn’t care how the fire looks. A failed liner means exhaust, carbon monoxide, and moisture are moving through spaces they were never meant to touch. In Rockville homes with older Olympia systems, we’ve seen cracked flue tiles and rusted liners that went unnoticed for years. The honest answer: if the camera shows a failed liner, you shouldn’t burn until it’s fixed. Call (240) 716-5865 for the camera inspection and the verdict.
If you own an Olympia Chimney system in Rockville and you’re seeing water stains, smelling exhaust, or staring at a bad inspection report, call Top Hat Chimney at (240) 716-5865.
