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 Cap & Crown in Towson: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Towson, typically completing most jobs in a single visit with upfront pricing agreed before we start. A standard Olympia Chimney cap replacement runs $280-$520, while crown repair or coating ranges $340-$780 depending on accessibility and flue count. We’re not affiliated with Olympia Chimney - we’re an independent service provider who stocks the parts and knows the product lines.
This page is for Towson homeowners who already have an Olympia Chimney system installed and need the cap or crown addressed. Maybe water’s getting in, or a neighbor spotted rust streaks, or the crown has hairline cracks that widen every freeze-thaw cycle. Whatever brought you here, we’ll give you a straight answer and a number you can count on. Call (443) 785-3816 - a live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 304 stainless single-flue caps: The mesh on these can clog with Towson’s heavy oak and maple leaf fall, especially in neighborhoods like Rodgers Forge where mature canopies overhang roofs. When airflow drops, smoke backup and moisture retention accelerate rust at the base flange. We pull the cap, clear the mesh properly without warping it, and reseat with a fresh bead of high-temp sealant. If the flange is too far gone, we source a direct-fit replacement rather than forcing a generic cap that won’t seat square.
- Olympia Chimney multi-flue caps (galvanized or stainless):strong> The cross-breaks in the lid can pool water if the pitch settles over years, which we see often on the older colonials north of downtown Towson where freeze-thaw is aggressive. That pooled water works into the corners and rusts from the inside out. We check lid pitch with a straightedge, replace if the break is flattened, and always verify the side screening hasn’t pulled away from the frame - a gap that lets squirrels in but won’t show from the ground.
- Olympia Chimney wind-directional caps: The rotating collar seizes when Towson’s coastal humidity combines with creosote glazing, common on fireplace flues that see intermittent use. A stuck directional cap becomes a non-directional cap, and in a stiff wind you’ll get down-drafts that blow smoke into the room. We disassemble the collar, clean the pivot and bushing, and lubricate with only high-temp graphite - standard oils cook off and re-seize within a season. If the bushing is worn oval, replacement is the only fix.
- Olympia Chimney poured concrete crowns: These are factory-cast to spec, but the pour quality varies batch to batch. We’ve opened crowns that looked fine from the roofline but had internal voids where water had been collecting for years, particularly on installations from the mid-2000s. Our Level-2 camera inspection catches this before we quote - we won’t tell you a crown needs coating until we’ve photographed the underside and shown you the spalling or delamination ourselves.
- Olympia Chimney chase pan replacements (prefab chimney systems): The factory chase pans are galvanized steel with a limited lifespan in Towson’s climate - we regularly see them rust through at the corners in 12-15 years, faster if the chimney sits on a north-facing wall that never fully dries. Olympia’s replacement pans are available, but we also fabricate custom stainless or copper pans in-house when the chase dimensions are non-standard or the homeowner wants the longer lifespan. We always slope the pan properly toward the scupper - a detail some installers skip that costs you five years of service.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, day or night. We ask about your Olympia Chimney system if you know the model, your symptoms, and when you’re available. We book a window and stick to it.
- 2
Level-2 camera inspection on arrival. Our technician photographs the cap or crown from the roof and runs a camera down the flue to check for hidden water damage or liner compromise. You see the photos; we explain what we’re looking at in plain English.
- 3
Parts decision - OEM Olympia Chimney or quality aftermarket. If your cap is a current Olympia part and the price makes sense, we order direct. If the lead time stretches past burning season or the OEM price is out of line, we source from Gelco or Famco with equivalent or better specs, always noting the substitution in writing.
- 4
The repair or replacement. Crown work gets wire-brushed, primed with CrownCoat or HeatShield CC-100 depending on crack depth, and finished to factory slope. Cap replacements get sealed with high-temp silicone, not generic caulk that hardens and splits. We check spark arrestor mesh count against code while we’re up there.
- 5
Function test and documentation. We run a draft test, verify no smoke spillage, and photograph the finished work. You get a report with before-and-after images and our written verdict on anything else that needs attention now versus what can wait.
- 6
Cleanup, payment, and guarantee. We haul off the old material. You pay the upfront price we quoted - no add-ons, no surprises. The 90-Day Done Right Promise goes into effect in writing before we leave.

These are real Towson numbers, not national averages padded for your zip code. A steep slate roof in West Towson costs more to access safely than a walkable ranch in East Towson. We give you the exact figure before we start, and that’s the figure on the invoice. Call (443) 785-3816 for a free estimate - we bring the camera, not a sales pitch.

We carry DuraFlex, HeatShield, Gelco, and Famco alternatives that meet or exceed OEM spec, and we explain the trade-off so you decide. Russell Haines and our crew have worked on Olympia Chimney systems from rowhouses near Goucher College to the older colonials off Joppa Road - we know how Towson’s freeze-thaw cycles and coastal humidity treat these products, and we build that into every recommendation.
A clean chimney doesn’t announce itself - it just works. The same goes for a cap and crown done right.
FAQs
No - installing a cap or performing crown maintenance does not void your factory warranty, provided the work is done correctly and documented. As an independent Olympia Chimney service provider, we note all part numbers and installation details in our report so you have a record if a warranty question ever arises on the liner or other components. Call (443) 785-3816 if you’d like us to review what’s covered before we start.
A 304 stainless Olympia Chimney cap should last 15-20 years in Towson’s climate, but galvanized models often show corner rust in 8-12 years, especially on north-facing chimneys that stay damp. Heavy tree cover accelerates mesh clogging and corrosion. We inspect for free during any service call and tell you honestly whether yours has another season or needs attention now.
We can coat and seal a crown with hairline cracking and sound structural integrity - that’s the majority of what we see. Replacement is only necessary when there is significant spalling, exposed rebar, or delamination visible on camera. We show you the photos and explain which category you’re in before quoting either option. Call (443) 785-3816 for an exact assessment - estimates are free.
A cap sits on top of a masonry chimney flue to keep rain and animals out. A chase pan is the metal roof of a prefab chimney chase - essentially a larger, sloped pan that sheds water away from the framed enclosure. Olympia Chimney makes both, and we service both, but the parts are not interchangeable. If you’re unsure which you have, describe it when you call and we’ll know from your chimney type.
We book most cap and crown work within a few days, and we complete most jobs in a single visit because we stock common Olympia Chimney sizes and compatible alternatives. We don’t promise same-day dispatch - we promise we’ll be there when we say, with the right parts and a price agreed upfront. Call (443) 785-3816 to get on the schedule.
