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 Repair in Gaithersburg: What to Know First
As an independent Olympia Chimney service provider in Gaithersburg, we repair Olympia Chimney liners, caps, and venting systems with OEM or quality aftermarket parts - most jobs completed in a single visit with upfront pricing agreed before we start. Typical turnaround from call to repair is a few days, not weeks. We do not mark up parts to pad the bill, and we do not recommend work you can see for yourself is unnecessary.
This page is for homeowners in Gaithersburg, Kentlands, and surrounding Montgomery County who have an Olympia Chimney product installed and need straight talk about what’s failing, what it costs, and who can fix it right. If that’s you, call (301) 719-5236 - a live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti stainless liners: We see these in Gaithersburg split-levels from the 1970s and 80s. The titanium-stabilized alloy resists acid corrosion better than plain 304, but creosote buildup in the flex joints still causes pinhole leaks at the seam welds. We camera-inspect the full length, then either spot-repair with HeatShield cerfractory foam for minor breaches or pull a new DuraFlex 316Ti liner if the damage runs more than a foot.
- Olympia Chimney smooth-wall round liners (6″ and 8″): The tight corrugation that gives these their excellent draft also traps moisture against the outer wall in Gaithersburg’s humid summers. We’ve pulled liners in the Kentlands area where the bottom three feet looked like shredded foil from freeze-thaw cycling. Our fix: remove the damaged section, verify the remaining liner is sound with a pull-through camera, and splice in a matching gauge replacement with a proper condensation collar.
- Olympia Chimney top-sealing dampers: The cast-aluminum frames warp after a decade of Maryland temperature swings, especially on south-facing chimneys in neighborhoods like Old Towne. The damper won’t seat fully, and you’re heating the neighborhood. We measure the flue opening precisely - Olympia’s 13″ x 13″ is not actually 13″ x 13″ once the mortar has aged - and install a Gelco damper with a stainless frame that tolerates the expansion better.
- Olympia Chimney wind-directional chimney caps: The rotating hood seizes when the brass bushing corrodes from Gaithersburg’s road salt and acid rain. A stuck cap spins in the wind, loosens the mounting screws, and eventually departs for your neighbor’s yard. We replace the bushing assembly where possible, or fit a new Famco or Copperfield cap with a sealed bearing design that doesn’t need annual lubrication.
- Olympia Chimney firestop and support kits: The intumescent firestop foam in older kits degrades after 15-20 years and crumbles when disturbed. In Gaithersburg’s older colonials with balloon framing, this is a real hazard - fire can travel the wall cavity. We remove the old material completely, install new firestop to current ICC code, and document with photos for your insurance file.

FAQs
No - independent repair by a qualified technician does not void your warranty, provided OEM or equivalent parts are used and installation follows manufacturer specifications. We document every part number and procedure so your warranty record stays clean. Call (301) 719-5236 if you need warranty paperwork for your files.
Common liners, caps, and dampers ship within 2-3 business days; rare sizes or discontinued series may take a week. We stock the most frequent Olympia Chimney repair items and can often substitute a DuraFlex or Gelco equivalent that meets or exceeds OEM specs if you’re in a bind. Call us to check current availability.
If the damage is localized - under 12 inches of breach, no adjacent deterioration - spot repair with HeatShield or a section splice is cost-effective and durable. If the liner shows multiple failure points, corrosion thinning, or improper sizing for your appliance, full replacement is the smarter money. We’ll show you the camera footage and give you both numbers so you decide. Call (301) 719-5236 for a free inspection.
Every year, per NFPA 211 - especially if you burn regularly in Gaithersburg’s heating season. Olympia Chimney’s stainless liners resist corrosion but don’t prevent creosote buildup or physical damage from chimney fires. An annual Level-2 inspection catches liner breaches, cap failures, and damper wear before they become expensive problems. Call us to schedule.
A breached liner or failed damper lets combustion gases, including carbon monoxide, leak into living spaces - and creosote accumulates faster in damaged flues, raising fire risk. In Gaithersburg’s freeze-thaw climate, small mortar cracks become spalled brick and water intrusion within a season or two. The repair cost doesn’t go down with waiting. Call (301) 719-5236 for a free estimate - we’ll tell you honestly what can wait and what can’t.
If it’s worth heating your home with, it’s worth doing the maintenance correctly.
