This page is for Gaithersburg homeowners who already have Olympia Chimney products on their roofline and want specifics, not a sales pitch. We’ll cover how Olympia caps and crowns fail in this climate, what repair versus replacement looks like, and what it should cost here.

Key Takeaways

• Olympia caps fail most often at the screen seam and at the mounting collar, not the hood itself.
• Crown damage on Gaithersburg brick chimneys is usually freeze-thaw spalling, and it’s repairable if caught before water reaches the flue liner.
• We stock common Olympia cap sizes and can order series-specific parts faster than most general contractors in Montgomery County.
• Every estimate includes camera photos of your cap and crown before we quote a dollar figure.

How Olympia Chimney Products Fail - and How We Fix Them

• Olympia Voyageur and Legacy caps: screen seam separation. The stainless mesh on these models is crimped into the hood at the factory. After six or seven Gaithersburg winters, thermal expansion works that crimp loose and the screen starts peeling away from the lid. That’s not a bad installation, it’s a materials reality. The fix is usually a full cap replacement rather than a field repair, because the crimp channel can’t be re-seated once it’s stretched. We see this on homes throughout Kentlands, Lakelands, and the older neighborhoods off Goshen Road.
• Olympia multi-flue caps with rust at the corner welds. The larger custom-width Olympia caps, especially those covering two or three flues, are built from sheet stainless with welded corners. The welds are the first place oxidation shows up, particularly on caps exposed to prevailing wind off the Washingtonian corridor. We inspect every weld with a close-up camera pass before recommending replacement. If the weld has surface rust but no penetration, a stainless passivation treatment and re-seal buys you several more years for under $200.
• Crown spalling on Gaithersburg brick chimneys with Olympia caps still intact. This is the failure that confuses people. The cap looks fine, but the cement crown underneath is cracking and shedding. It happens because Gaithersburg gets about 40 inches of rain a year and regular freeze-thaw cycles. Water sits in micro-cracks in the crown, freezes, expands, and pops the surface. We fix this by grinding out the damaged areas, applying a bonding agent, and recasting with a proper Portland-based crown mix that includes a flexible acrylic modifier, or we coat a structurally sound crown with a breathable elastomeric sealant rated for chimney use.
• Olympia cap mounting collars loosening on clay tile flues. The clamp-style mounting on Olympia round caps is designed for a tight fit on both metal and clay liners. On older Gaithersburg chimneys with clay tile, the outer surface of the tile can erode unevenly, and the clamp loses grip over time. A loose cap rocks in the wind, which then enlarges the gap and lets water in around the flue opening. We correct this with a stainless flue adapter or a custom shim that re-centers the cap and locks it down. This isn’t a part Olympia sells, and it’s one of the fixes we’ve developed from field work.
• Olympia draft-inducing caps with internal baffle corrosion. Some Olympia models, like the high-wind series, have an internal steel baffle that redirects downdraft. That baffle catches every bit of moisture and acidic flue gas that rises through the flue. After enough seasons it corrodes from the inside while the cap exterior looks brand new. You can’t see this from the ground. We find it with the camera. If the baffle is compromised, you’re not getting the draft performance you paid for, and the fix is replacement, not patching.

Our Olympia Chimney Chimney Cap & Crown Process

1. 1
   Call and tell us what you’re seeing. When you call (240) 220-9395, a live person answers, either Corrine Halstead or one of our office staff who actually knows chimneys. We ask what’s wrong, where you are in Gaithersburg, and what kind of cap you think you have. If you can read a model number off the cap or a plate, that helps us bring the right parts.
2. 2
   Camera-scan inspection, no guessing. We don’t quote a repair from the ground. We get on the roof, pull the cap if needed, and run a camera down the flue. You see the footage. We measure the flue I.D., check the crown surface with a moisture meter, and photograph everything. This is Clause 4 of the Haven Standard, and we’ve done it this way since 2009.
3. 3
   Parts decision: OEM Olympia or quality aftermarket. If the cap needs replacing, we discuss whether an Olympia replacement is the right call or whether an equivalent stainless cap from our other suppliers, Famco and Copperfield, does the job at a better price. We’re independent, so we recommend based on what we’d put on our own roof, and we tell you why. Crown repairs never involve “crown kits” from a big-box store. We mix our own material and stand behind it.
4. 4
   Written price before anything starts. Clause 1 of the Haven Standard means you get a written scope, a written price, and a written warranty before our techs touch a tool. No verbal estimates, no “we’ll see when we get in there.” If we find additional damage after opening something up, we stop and send you photos before we proceed.
5. 5
   Repair or replacement, then the test. We do the work methodically. Cap installations get a pull test to confirm the mounting is rock solid. Crown work gets a water-shed test, and we verify moisture readings have dropped. Our techs are background-checked and uniformed, with their license number on the work order.
6. 6
   Photo record and warranty, every time. Before we leave, you get a documented photo record of what was done, including before and after shots. Every job is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right. No fine print, no re-inspection fee.

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

Corrine Halstead, our owner, came up through the trade at New York City College of Technology before moving her work into Montgomery County, and she’s been servicing Gaithersburg’s older brick-stack homes long enough to know exactly how they behave. The neighborhood around Rio Washingtonian Center, those 1970s and 80s houses with the original clay liners and mortar crowns, they’re a predictable combination of creosote and wear, and we know what to look for before we even get on the roof.

What we bring to an Olympia job: techs who know the product line and its failure points, a camera on every inspection, and a written price before work starts. We’re not an Olympia dealer, and we’re not going to push OEM parts when an aftermarket Famco cap is the better buy for your roof. We also work with DuraFlex, HeatShield, and Gelco materials, so if a damaged crown has already compromised your flue liner, we can handle that repair in-house rather than sending you to another company.

The camera doesn’t guess. Neither do we. Every estimate includes measurements and photos, not approximations. And because we answer the phone 24/7, you’re never waiting on a callback when water is coming through your ceiling.
