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 Rockville: What to Know First
We install, replace, and repair Olympia Chimney caps and crowns in Rockville, Maryland, and most jobs are completed in a single visit once we’ve assessed the existing setup and ordered the right parts. A standard Olympia Chimney cap replacement in Rockville runs $385 to $710 installed, while a poured crown replacement typically lands between $900 and $1,600 depending on flue count and masonry condition. This page is for Rockville homeowners who own an Olympia Chimney product, or think they might, and want to know what it costs, how it fails, and what the fix actually looks like. Call (571) 376-7052 and a live person answers, 24/7.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney stainless steel caps corrode at the screen weld points first. We see this in Rockville’s older split-foyer and colonial homes, where a decade of Montgomery County humidity plus creosote exposure eats the fine screen mesh before the cap body shows any wear. The failure isn’t structural; it’s spark and animal exclusion, which is the whole point of the cap. We replace the full cap rather than patch screens, because a patched screen on an Olympia cap fails again within two seasons.
- Olympia Chimney’s terra cotta flue tile crowns crack along the overhang edge. The crown shoulders on Olympia tile-liner installations are poured thin at the outer lip, and Rockville’s freeze-thaw cycles work that lip loose. Water gets behind the crown, then into the flue chase, then into your ceiling. Our fix is a full crown removal and re-pour with a proper drip edge, not a coat of crown seal smeared over failing concrete.
- The multi-flue Olympia Chimney caps collect leaf litter in Rockville’s fall. Rockville’s tree canopy, especially near King Farm and West End, drops enough leaf matter onto wide multi-flue Olympia caps to restrict draft within a single season. The cap itself doesn’t fail, but the restricted airflow mimics a failing cap, and the fix is a service call with a documented photo record showing what we removed.
- Olympia Chimney’s slip-in caps loosen on unlined or rough terra cotta flues. The friction fit that works on a smooth steel liner doesn’t hold on Rockville’s older masonry chimneys, where terra cotta flues have spalled and roughened. The cap starts to wobble, then tilt, then it’s resting sideways against the flue wall. We either re-seat with a proper mechanical fastening or swap to a multi-flue cap that anchors to the crown itself.
- Olympia Chimney’s galvanized cap bases rust at the mounting screw points. This is the one we see most often: the cap body is fine, but the base collar where the mounting screws pass through has rusted through. The screws hold, but water weeps in around them. We replace with an Olympia stainless steel cap or a quality aftermarket equivalent that uses a fully welded base rather than a screw-through design.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and get a real person. You tell us your chimney type, home style, and what you’re seeing. We schedule the visit and you get a text when the named tech is on the way.
- 2
Camera inspection first. We run the camera down the flue before touching a single part. Corrine Halstead has been doing Level 2 camera-scan inspections since 2009, and the camera comes before the wrench. The picture tells us what’s actually failing.
- 3
Written scope and written price. We hand you a written line-item price for cap replacement, crown work, or both, with the exact Olympia Chimney or quality aftermarket part named. No work starts until you approve it in writing.
- 4
Repair or replacement. We remove the old cap, prep the crown or flue collar, install the new Olympia Chimney or equivalent part, and document every step.
- 5
Post-install camera re-scan and photo record. You get a documented photo record of the finished work, including the re-scan footage. This is Clause 4 of the Haven Standard, and it’s been our default since 2009.
- 6
Cleanup and warranty. We leave the roof and hearth as we found them, and your written warranty is in your hand before we leave the driveway.

FAQs
No. Replacing a cap is a standard maintenance item and doesn’t void an Olympia Chimney warranty on the liner or appliance itself. What can void a warranty is using a non-listed part that doesn’t meet the original listing requirements, which is why we verify part compatibility before we order anything. We’ll tell you in writing if the replacement part is OEM, equivalent, or a different specification, and we’ll flag any warranty implications before you approve the work.
Most single-flue cap replacements in Rockville are done in one visit, because common Olympia Chimney cap sizes are stocked locally. Multi-flue caps and custom caps take 3 to 7 business days to fabricate or special-order. Crown replacements are weather-dependent; a cold snap or heavy rain will push the job a day or two. Call (571) 376-7052 and we’ll give you a straight answer on timing before you commit to anything.
We only recommend sealing when the crown is structurally intact with hairline cracks. If the crown has spalled at the edges, pulled away from the flue tiles, or is letting water run down the flue chase, sealing is wasted money; it’ll fail within a year or two. We’ll show you the camera footage and photos of the crown condition and give you a written recommendation. If a seal will hold, we’ll tell you that, too. We won’t sell you a crown you don’t need.
Yes. Olympia Chimney caps are engineered for the Olympia liner and flue system, so the fit is tighter and the mounting style is more specific than a universal cap. If your existing cap was never seated properly, or if it’s on an unlined terra cotta flue, the install will fail early. We confirm the flue type and measurements on the roof, then order the cap that actually matches.
Water is the main threat. In Rockville, freeze-thaw cycles turn a cracked crown into a broken crown in one winter, and a missing or failed cap lets water, birds, and leaves into the flue. Water in the flue accelerates liner corrosion and creosote adhesion. The repair cost goes up the longer the water runs. Call (571) 376-7052 for a free estimate, and we’ll show you exactly what you’re working with before you spend a dime.
