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’re an independent Olympia Chimney service provider in Rockville, and we handle chimney cap installation, cap replacement, crown repair, and crown coating for Olympia systems every week. Most cap and crown work on Olympia Chimney products takes a single visit, and we give you the full price before a tool comes off the truck. If the crown can be coated instead of rebuilt, we’ll say so. Call (240) 716-5865 for a free estimate.
If you own an Olympia Chimney system in Rockville, this page is for you. We’ll walk through what actually fails on these products, what it costs to fix, and how to tell if the repair can wait. No scare tactics, no padded invoices. Wendell Pike has been pulling caps off Rockville chimneys for over twenty years, and we’ll tell you straight whether the job needs doing.
How Olympia Chimney Products Fail - and How We Fix Them
- Cracked crowns on Olympia stainless fireplace systems. The Olympia Ventis and Olympia fireplace lines often ship with a poured concrete crown. In Rockville, freeze-thaw cycles work hairline cracks into that concrete within five to seven years. Water gets in, freezes, expands, and spalls the crown surface. We grind out the cracks, apply a flexible crown coat, or rebuild the crown entirely if it’s gone past coating.
- Cap screen clogging on Olympia air-cooled chimney systems. Olympia air-cooled pipe relies on airflow between the inner and outer walls. The cap’s mesh screen catches leaves, seed pods, and the occasional squirrel nest (Twinbrook has no shortage). Once airflow drops, the pipe runs hot and draft weakens. We pull the cap, clear the screen, and check the air slots before reinstalling or replacing the cap.
- OEM cap rust-out on older Olympia units. Olympia’s factory caps are functional but not always stainless on every model year. We regularly replace rusted OEM caps on Rockville homes built in the 1990s and early 2000s. We use quality stainless aftermarket caps sized to the exact pipe diameter, which typically outlast the original.
- Improper cap-to-flue matchup from prior installations. Some Olympia chimneys we see in Rockville have caps that were never matched to the flue correctly in the first place. Wrong diameter, wrong screen spacing, or a cap sitting loose on the flue tile. We measure the actual flue opening and the appliance requirements before ordering anything. One size fits all means one size fits wrong.
- Multi-flue crown failure on Olympia masonry chimneys. When an Olympia liner or HeatShield system has been installed in a larger masonry chimney, the crown often spans multiple flues. Unsealed expansion joints between flues are a common failure point. Water chases the joint, soaks the masonry, and eventually shows up as efflorescence or spalling brick below the crown line. We seal the joints properly and make sure the crown sheds water away from the flue openings.
Our Olympia Chimney Chimney Cap & Crown Process

Call and talk to a live person. You reach us, not a call center. We get your address, what you’re seeing, and set a real arrival window. If the schedule slips, we call you.

On-site inspection. Wendell or one of his crew gets on the roof and looks at the cap, crown, flue, and the top few feet of the chimney. We take photos and show you what we found.
- 3
Straight answer, priced before work starts. We tell you what needs doing, what can wait, and what it costs. The number you hear is the number on the invoice. If you want a second opinion on another company’s written estimate, that’s free.
- 4
Parts decision. We check whether OEM Olympia parts make sense for your system or whether a quality aftermarket cap or crown coat will do the job better for less money. We never oversell OEM. We never undersell what actually protects your chimney.
- 5
The repair, done properly. Whether we’re coating a crown, rebuilding it, or swapping a cap, we take the time to do it right. The top of the chimney is the most weather-exposed part of your house. Cutting corners there means doing the job again in two years.

Cleanup and follow-up. We leave the roof and the ground around the chimney clean. Every job carries the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back at no cost.

We’ve been doing chimney work in Rockville since 1999. That means Wendell has seen the same Olympia systems age through two decades of Maryland weather.

You’ll get a local owner-operator whose name is on the work and who runs into you at the grocery store. We answer the phone 24/7 with a live person. We also work with DuraFlex, HeatShield, and Gelco lines, so we can give you a straight recommendation across brands, not push whatever’s on the truck. The 90-Day Done Right Promise is on every invoice. If it doesn’t need doing, we’ll tell you.
FAQs
A standard cap replacement on an Olympia Chimney system in Rockville runs $180 to $380, while crown work ranges from $350 for coating up to $1,400 for a full rebuild. Most combined cap and crown jobs fall between $500 and $1,800. The exact price depends on roof access, flue count, and how far the damage has gone. Call (240) 716-5865 and we’ll give you a straight number before any work begins.
No. We are an independent Olympia Chimney service provider, not an authorized dealer or warranty center. That independence means we can recommend an aftermarket cap if it’s honestly better than the OEM part, and we can tell you if a warranty claim is worth pursuing without trying to sell you a replacement you don’t need.
It can, if the manufacturer’s warranty terms require OEM parts and you choose an aftermarket cap. On most Olympia systems, a properly sized stainless aftermarket cap won’t affect the chimney body warranty, but if your system is still under manufacturer coverage, we’ll check the terms before ordering anything. We’ll also tell you plainly if the OEM part is the smarter choice.
Usually, yes. Most Rockville cap and crown repairs are done in a single visit, and we keep common cap sizes and crown coat materials on hand. Custom or multi-flue caps may take a few days to order. We’ll give you a specific arrival window and call if anything changes.
If the crown has surface crazing or hairline cracks, coating usually does the job. If the concrete is spalling, the crown surface is deeply pitted, or chunks are coming loose, rebuild it. We’ll take photos and show you exactly what we’re seeing before recommending either route. You’ll never have to take our word on a repair you can’t see for yourself.
Water gets further into the chimney. In Rockville’s freeze-thaw winters, that means more spalling, more brick work, and eventually a liner or flue repair you could have avoided. The cap and crown are the cheapest waterproofing you’ll ever do on the chimney. If yours is still sound, we’ll tell you to wait. If it’s not, don’t hand the chimney another winter. Call (240) 716-5865 and we’ll take a look.
