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 Cleaning & Sweep in Gaithersburg: What to Know First
We provide independent Olympia Chimney chimney cleaning and sweep services throughout Gaithersburg, typically scheduling within a few business days and completing most jobs in a single visit. A standard Level 1 sweep and inspection for an Olympia Chimney system runs $89-$189, while Level 2 camera inspections with full documentation range $250-$400. We do not quote over the phone for anything we have not seen, and we do not sell repairs without photo evidence you can examine yourself.
This page is for Gaithersburg homeowners who heat with wood or gas through an Olympia Chimney liner, cap, or venting component and need the flue swept, inspected, or cleared of creosote buildup before the burning season. If you are in the Kentlands, Lakelands, or one of the older colonials off Diamond Avenue, we have likely worked on a chimney like yours. Call (301) 719-5236 to speak with a live person now.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti stainless liners with premature weld-seam corrosion. We see this in Gaithersburg homes that burn seasoned hardwood but run cooler, dampered fires, especially in shoulder seasons. The acidic condensate pools at the lower weld ring and eats through from the inside before the liner shows external damage. We pull a camera, document the seam condition, and if the breach is localized, we can install a HeatShield cerfractory sleeve rather than full liner replacement. Done right, and we stand behind it.
- Olympia Chimney Gelco-style caps with mesh clogging from Montgomery County pollen and maple samaras. The ¾-inch mesh that ships standard on many Olympia Chimney caps is correct for spark arresting, but in Gaithersburg it fills with spring debris faster than coarser aftermarket mesh. A blocked cap drives smoke backup and accelerates creosote formation inside. We clean the flue, clear the mesh, and if the homeowner wants, we source a Famco cap with ⅝-inch stainless mesh that breathes better through our pollen-heavy springs without voiding the underlying liner warranty.
- Olympia Chimney flexible liner installations with inadequate support at the thimble. The collar connection on older Olympia Chimney 5.5-inch flex can sag where it exits the masonry thimble, creating a low spot that collects creosote and condensate. In a Level 2 inspection we spot the belly, measure the draft, and if the liner is otherwise sound, we install a DuraFlex support plate and re-tension the run. No guesswork. Photos you can see, a plain-English verdict.
- Olympia Chimney air-cooled chimney systems with blocked annular space. These were common on 1980s and 1990s Gaithersburg builds, especially the split-levels off Goshen Road. The air gap between inner and outer walls packs with soot during a chimney fire or from years of poor draft, and the chimney overheats. We run a borescope through the cooling channels, clear the obstruction with compressed air and mechanical picks, and test draft before we sign off. Russell Haines has caught three of these in the past two years that other sweeps diagnosed as “needs full rebuild.”
- Olympia Chimney factory-built metal chimney with deteriorated storm collar seal. The factory silicone bead at the roof penetration dries out after 12-15 years in our freeze-thaw cycle. Water tracks down the exterior, rusts the chase cover from underneath, and drips onto the firebox. During a sweep we inspect the collar, reseal with high-temp silicone rated for Olympia Chimney’s listed clearances, and if the chase cover is too far gone, we fabricate a replacement from Copperfield galvanized or stainless stock. A square deal: no surprises on the bill.
Our Olympia Chimney Chimney Cleaning & Sweep Process
- 1
Live answer, real scheduling. A person picks up when you call (301) 719-5236, 24 hours a day. We book a window, send a confirmation, and call ahead when the technician is en route.
- 2
Arrival and protection. Our technician arrives in a marked truck, uniformed, background-checked. Floor coverings go down before any tool touches your hearth. We ask about the appliance, fuel type, and any symptoms you have noticed.
- 3
Level 1 or Level 2 inspection. Every sweep starts with the NFPA 211 inspection appropriate to the system. For Olympia Chimney liners and factory-built units, we pay particular attention to listed clearances, support spacing, and collar connections. If we see something that needs a camera, we explain why before we proceed.
- 4
Sweep and mechanical cleaning. We use rotary whips and polypropylene brushes sized to your Olympia Chimney flue diameter, not generic one-size-fits-all tools. Creosote stages 1 through 3 are removed and collected in HEPA-contained vacuums. The firebox, smoke shelf, and damper get hand-cleaned.
- 5
Camera documentation and plain-English verdict. For Level 2 work, we record the full flue scan. You see the footage. If a repair is needed, we show you the exact location, explain the cause, and quote upfront. Nothing is recommended without evidence you can verify yourself.
- 6
Cleanup, written report, and guarantee. We leave the work area cleaner than we found it. You receive a written summary with photos, the sweep certificate for your insurer, and the 90-Day Done Right Promise. In writing, no arguing. If it’s worth heating your home with, it’s worth doing the maintenance correctly.
What Olympia Chimney Chimney Cleaning & Sweep Costs in Gaithersburg
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Level 1 sweep and inspection | $89-$189 | Number of flues, accessibility, amount of creosote |
| Level 2 camera inspection | $250-$400 | Height of chimney, number of appliances, need for roof access |
| Creosote removal (heavy Stage 3) | $150-$300 additional | Mechanical removal vs. chemical treatment, liner material |
| Cap cleaning and mesh service | $75-$150 | Height, condition of fasteners, need for replacement hardware |
| Olympia Chimney liner spot repair (HeatShield sleeve) | $800-$1,800 | Length of affected section, access, whether surrounding liner needs support |
These are Gaithersburg market ranges for Olympia Chimney systems, not national guesses. A straightforward annual sweep on a single-flue gas insert with an Olympia Chimney liner lands near the lower end. A neglected wood-burning system with a blocked cap, heavy creosote, and a suspected liner breach will run higher. We give you the exact number before we start. Call (301) 719-5236 for a free estimate.

FAQs
No. As an independent Olympia Chimney service provider, we perform maintenance according to NFPA 211 standards, which is what the warranty requires. Using an unauthorized installer for new liner work can complicate warranty claims, but routine cleaning and inspection by a qualified sweep does not affect coverage. If you have a specific concern, we will review your documentation before we start. Call (301) 719-5236 and we will walk through it.
For wood-burning systems, the NFPA recommends annual inspection and cleaning as needed. In practice, Gaithersburg’s mix of humid summers and cold winters means creosote can hydrate and harden if left through the off-season, so we advise not skipping a year. Gas systems with Olympia Chimney liners should be inspected annually for condensate damage and debris blockage, though they typically need less aggressive mechanical cleaning. Call (301) 719-5236 to schedule.
We can source OEM Olympia Chimney components when they are available and appropriate. For many repairs, we use professional-grade aftermarket parts from DuraFlex, HeatShield, Gelco, Famco, or Copperfield that meet or exceed OEM specifications and are listed for the application. We explain the choice and show you the part before we install it. A square deal: no surprises on the bill.
You do not have to guess. Our Level 1 inspection evaluates whether the system is safe to use as-is. If we see something that needs a closer look, we recommend a Level 2 camera inspection and show you exactly what we found. We have told homeowners their liner can wait another season, and we have told others to stop using the fireplace immediately. The camera does not lie, and we do not sell what the picture does not support. Call (301) 719-5236 for a free estimate.
Stage 1 creosote becomes Stage 3, which is harder to remove and more flammable. In Olympia Chimney stainless liners, trapped moisture and acids accelerate weld-seam corrosion. Blocked caps or deteriorated storm collars let water in, and water does more damage than fire. The risk is real, but we do not scare-sell. We inspect, we document, and we tell you honestly whether you can wait. Call (301) 719-5236 to find out where you stand.
