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 Catonsville: What to Know First
We install, replace, and repair Olympia Chimney caps and crowns in Catonsville, and most jobs are done within one visit once we’ve had a look at the flue and taken measurements. A standard single-flue Olympia cap replacement around Catonsville runs between $220 and $410 installed, and a full crown repair or recoat typically lands between $450 and $900 depending on size and condition. We quote a flat price before the first tool comes off the truck, so that number is what you pay, tax and all.
This page is for Catonsville homeowners who have an Olympia Chimney cap or crown that is failing, rusting, cracking, or pulling away from the flue. If you aren’t sure what you have, call (443) 332-7798 and Wendell or one of his crew will sort it out over the phone.
How Olympia Chimney Products Fail - and How We Fix Them
We have pulled more Olympia caps off Catonsville chimneys than we can count, and the failures follow patterns. Here is what we see and what we do about it.
- Rust-through on the Olympia Mesh-Style Caps. The galvanized mesh panels on Olympia’s standard black-painted caps start showing rust bloom around the welds after four to six years of Maryland weather. Once the mesh gets crunchy, it no longer keeps squirrels and birds out of the flue, and it becomes a catch point for wet leaves. We replace the cap with either a new Olympia unit or a heavier-gauge aftermarket cap that will hold up longer in Catonsville’s damp springs. Wendell will show you the difference on the roof before you decide.
- Crown cracking from freeze-thaw cycles. Catonsville sits close enough to the Patapsco Valley that winter nights drop below freezing and daytime sun warms the crown back up. That repeated cycle opens hairline cracks in concrete crowns, and water gets in. On Olympia installations, the crown is usually poured concrete, which holds up fine until the surface wash breaks down. We repair with a flexible crown coat or full recoat, depending on how deep the cracks go.
- Undersized caps installed by other contractors. We see this a lot in the older neighborhoods off Frederick Road. Somebody put an 8-inch cap on a 13-inch outside-diameter flue, which chokes the draft and leaves the flue tile shoulder exposed to rain. Olympia makes properly sized caps for most flue dimensions, but whoever installed it didn’t measure. We measure every flue before ordering or installing anything, and we never face-screw a cap onto a tile that’s already spalling.
- Pest entry through damaged Olympia spark arrestor mesh. The mesh on Olympia caps is there for a reason. Once it’s dented or torn, starlings and squirrels find their way down the flue. We have pulled nests out of chimneys in Catonsville that had been used for two seasons. Slapping a new cap on before clearing the nest just traps the problem. We clear, then cap, then run a camera down the flue so you can see it’s clear.
- Crown wash corrosion from a missing drip edge. Olympia’s factory crowns shed water straight down the brick face if the cap doesn’t overhang enough. That constant water on the masonry stains the brick and eventually erodes the mortar joints below the crown line. We build that drip edge into the repair when we recoat, so water falls away from the chimney instead of down it.
Our Olympia Chimney Chimney Cap & Crown Process
Every Olympia cap and crown job in Catonsville follows the same path, and it starts with the phone call. Here is how it works.
- 1
You call. A live person answers, day or night. That might be Wendell himself. You describe what you’re seeing, and we’ll tell you honestly whether it sounds like an urgent repair or something that can wait a season.
- 2
We come out and inspect. No trip charge inside the county. We look at the cap, the crown, the flue tile, the mortar, and the flashing. If we can get on the roof safely, we do. If we can’t, we tell you why and figure out the next step.
- 3
We show you the evidence. Camera down the flue, photos from the roof. You see exactly what we see, on the spot. If the crown is fine and the cap has three good years left, we’ll say so and leave it alone.
- 4
We quote a flat price. OEM Olympia part or quality aftermarket, your call, with the trade-offs laid out plain. The number on the quote is the number on the invoice.
- 5
We do the job. Remove the old cap, repair or recoat the crown, set the new cap, seal everything, and test the draft.
- 6
We hand you the 90-Day Done Right Promise in writing. If anything isn’t right, one call brings us back at no charge.

FAQs
No. Installing a properly sized aftermarket cap does not void an Olympia Chimney warranty on other components, and we keep the installation photos and invoice on file if your home warranty ever asks. If you prefer OEM, we can order the exact Olympia replacement part for the job.
Most standard Olympia caps are available from our local supplier within two to three business days, and we keep the common sizes on the truck. Custom multi-flue caps take about a week, plus install time. Call (443) 332-7798 and we’ll give you a straight answer for your specific flue.
If the cracks are hairline and the crown surface is still sound, we can repair it with a flexible crown coat the same day. If the crown is crumbling, delaminated, or pulling away from the flue tile, a full recoat is the honest fix. Either way, you’ll see the condition on camera before we touch anything.
Water keeps getting in, and water is what rots the flue liner, damages the damper, and stains the ceiling around the chimney. After a few Catonsville winters, what started as a $300 cap job becomes a $3,000 liner job. One call to (443) 332-7798 gets you an honest read on whether you can wait or not.
