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 Cap & Crown in Ellicott City: What to Know First
We install, replace, and repair Olympia Chimney caps and crowns in Ellicott City, MD, with most jobs completed in a single visit once parts are on hand. A standard Olympia Chimney cap replacement in Howard County typically runs $325-$675 installed; a full concrete crown rebuild with an Olympia cap usually lands between $850 and $1,400 depending on flue size and crown condition. You’ll get a written price before any work starts, not a ballpark over the phone.
This page is for Ellicott City homeowners who already own an Olympia Chimney product, or who live in an older home where the cap and crown predate their ownership and they want to know what they’re actually looking at. If you’ve been told you need a new liner or crown and want evidence before spending money, call (443) 363-5262. Corrine Halstead and our crew will show you the camera footage first.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney makes solid stainless and galvanized caps, and their mesh sizing is generally good for Baltimore-Washington pest pressure. But Ellicott City’s humidity, freeze-thaw cycles, and decades of coal-era flue geometry create specific failure patterns we see repeatedly on Olympia installs. Here’s what shows up in Howard County homes:
- Olympia Champ series caps on older terra cotta flues with spalling at the top edge. The Champ’s clamp-on base relies on a square, sound flue tile to seat against. When the top clay tile has spalled (surface flaking and edge loss from decades of moisture absorption), the cap wobbles, gaps open, and rain runs directly down the outside of the flue liner into the smoke chamber. Fix: we grind back one course of damaged tile, install a stainless top mount that bridges past the defect, and seal the crown transition. The cap itself is often still fine; the flue mouth was the problem.
- Stainless Olympia multi-flue caps that fit fine when installed but bind and dent after a crown recoat. We see this on Ellicott City homes where a general contractor recoated the crown with too-thick acrylic coating and changed the elevation. The cap’s bracket arms ride up over the build-up, the mesh pulls taut, and one good wind storm twists the whole assembly. Fix: remove, measure the actual clearance, remount with an adjustable bracket kit rather than forcing the original fixed brackets.
- Galvanized Olympia caps on flues serving gas furnaces with continuous pilots, especially in older Ellicott City split-levels. The pilot never shuts off, so the flue stays damp and warm around the clock. Galvanized coating sacrifices itself to that moisture; the cap rusts at the seams first, usually within 7-10 years. Olympia’s own stainless options last far longer. Fix: replace with stainless, and if the furnace is venting into a masonry chimney, check the liner before you spend money on a cap that’s now protecting a liner that won’t last either.
- Missing or degraded crown around an Olympia cap that’s still in good shape. The cap gets blamed for a leak when the real culprit is the crown. Concrete crowns shrink and crack over 20-30 years, and once water works into the crown plane, it migrates into the masonry below. Fix: we’ll document the crack pattern on camera, give you the photos, and tell you if the cap can be reused or if its underside has already corroded enough to replace it. No pressure either way.
- Olympia caps with mesh that’s too coarse for Howard County’s chimney swift population. This one doesn’t show up in Olympia’s spec sheets. Standard ¾” mesh keeps out raccoons and squirrels but not chimney swifts; the birds wedge through and then can’t get back out. Fix: a custom cap with ⅝” mesh, which we order cut to the flue dimensions rather than pulling a stock size off the shelf.
Our Olympia Chimney Chimney Cap & Crown Process

Every Olympia Chimney job in Ellicott City follows the same steps, whether it’s a simple cap swap or a full crown rebuild:
- 1
Call arrives, a live person answers. That’s it. No voicemail tree. You’ll get a scheduled window and a named tech (Corrine or one of our crew).
- 2
We inspect before we touch anything. Camera down the flue, photos of the cap from above, crown surface checked for hairline cracking and delamination. This is NFPA 211 Level 2, and it’s included on every visit under Clause 4 of the Haven Standard.
- 3
We show you what we found on the spot. You’ll see the footage that justifies the quote. If the crown is sound and only the cap has failed, we’ll say so. If the cap is fine and the crown is failing, we’ll say that instead.
- 4
Written price and scope before anything starts. The line item covers cap model, material grade, mesh size if custom, crown material and thickness, and what happens to the old parts. Clause 1 of the Haven Standard: every job in writing, every time.
- 5
The install or repair. Crown work involves removing damaged material, forming the new crown with proper slope away from the flue, and installing a flexible sealant joint at the cap base so the cap can be removed later without chipping the crown. Cap-only jobs are measured, seated, and torqued to Olympia’s clamp specifications.
- 6
Photo record when it’s done. Before-and-after shots of the cap, the crown, and the camera stills from the flue interior. You keep that documentation for insurance, resale, or just your own file. The 365-Day Done Right Promise applies to the whole job: if it’s not done right, we make it right.

Why Ellicott City Homeowners Call Level Two Chimney Ellicott City for Olympia Chimney Work

Because we’ll show you the problem before we quote a dollar. We work on Olympia Chimney products as an independent service provider, not a factory-authorized shop, so when we tell you a cap is fine or a crown is done, that’s our read based on what the camera shows, not a warranty-insensitive sales target. Corrine Halstead has worked Howard County chimneys for the better part of a decade; she’s been in the stone-foundation homes near Historic Ellicott City on Main Street where nothing is plumb, nothing is square, and the clearance tolerances are tighter than the spec sheet allows for.
Technicians are background-checked and uniformed, and you’ll get a text when they’re on the way. If we find an Olympia cap that’s still serviceable but the liner behind it has failed, we’ll tell you that. We also carry and install DuraFlex liners, HeatShield resurfacing, and Gelco products, so when the fix isn’t just a cap and crown, we’re not jerry-rigging a multi-week subcontractor handoff. Live answers, 24 hours a day, every day. One number: (443) 363-5262.
FAQs
Most Olympia Chimney caps carry a manufacturer warranty against defects in materials, usually limited and pro-rated from the date of purchase. We’re not an Olympia-authorized shop, so we can’t process warranty claims for you; we can give you the documentation and photos you need to file one yourself. The bigger issue is installation: if a cap is installed out of square, over-torqued, or seated on a spalled flue tile, the cap fails early and the manufacturer will typically point to the install, not the product. Our documentation photo record gives you a paper trail either way.
Stock Olympia Champ caps and common stainless sizes are usually on our truck or available same week through our supply network. Custom caps, odd flue spans, and ⅝” mesh special orders typically take 7-10 business days to arrive. We’ll tell you at the quote stage which category your job falls into, in writing, before you’re committed.
Often, yes. If the cap is stainless, the mesh is intact, and the underside hasn’t corroded, there’s no reason to throw it out just because the crown failed. We’ll photograph the cap’s mounting surface and corrosion state, and tell you on the spot whether it’s worth reusing. If it’s galvanized and more than about eight years old in an Ellicott City weather exposure, you’re usually better off putting that money toward stainless rather than rebuilding a crown under a cap that’s already half-used.
It’s almost always a continuously burning pilot light or a humidity-trapping flue configuration, not a manufacturing defect. Galvanized coating oxidizes quickly when the flue stays warm and damp year-round. Wood-burning flues dry out between fires; furnace flues with standing pilots don’t. If the cap is galvanized on a gas flue, upgrade to stainless on the next replacement and you won’t revisit this for a long time.
Yes, and we’ll do it with a camera. This is where Corrine’s signature applies: the camera doesn’t soften what it finds, and neither do we. Bring us their written estimate and we’ll inspect the crown, take our own photos, and tell you whether the work is genuinely needed, can wait a season, or was never needed in the first place. That second opinion is free. Call (443) 363-5262 and we’ll schedule it.
