Olympia Chimney Crown Repair: The Woodland Hills Owner’s Guide
An Olympia Chimney crown repair in Woodland Hills typically runs $395 – $685 installed, depending on the crown’s size and how much of the original mortar bed needs to be rebuilt before the new crown goes on. We stock Olympia Chimney-compatible crown forms and the right mortar mixes on our trucks, so most repairs are completed in a single visit without waiting on a parts order. Most Woodland Hills homeowners discover the problem the same way: they see a hairline crack from the ground, or they notice water staining on the ceiling near the fireplace after one of our winter rain spells. By the time it’s visible from the yard, the crown has usually been letting water in for a season or two.
Here’s what this guide covers: which Olympia Chimney systems this applies to, the symptoms that mean the crown is already compromised, what a replacement actually costs, and when a repair is smarter than a full rebuild. We’re an independent chimney service company, not affiliated with Olympia Chimney, but we work with their components regularly because they’re spec’d on a huge share of Woodland Hills fireplaces.
Which Olympia Chimney Models This Applies To
Olympia Chimney is best known in Woodland Hills for their stainless steel chimney systems, especially the Champion and Ventis product lines. Both use a poured concrete crown that caps the flue and seals the gap between the outer chase and the chimney’s internal components. If you have a Ventis Class A or a Champion factory-built system, the crown we’re talking about is the concrete slab at the very top that slopes water away from the flue pipe. You can usually identify the system by the manufacturer label on the exterior pipe or on the interior firebox plate. If there’s no label, a quick measurement of the inner flue diameter (typically 5, 6, or 8 inches for these systems) narrows it down quickly.
We always ask the same question before ordering parts: What’s the outside diameter of the chimney chase opening? That dimension, plus the flue size, determines which crown form we use. We keep the common sizes on the truck, so when we arrive at a Woodland Hills home we’re not making you wait for a second trip.
One thing worth knowing: Olympia Chimney doesn’t sell a “replacement crown” as a plug-and-play part. The crown is poured on site, sized to your specific system. That’s why we use OEM-matching crown forms and a CrownCoat or equivalent polymer-modified mortar from brands like Gelco, which we stock alongside Olympia Chimney and other trade lines like DuraFlex and HeatShield. If a technician quotes you a “universal crown” without measuring your chase, walk away. Crowns are not universal.

Signs Your Olympia Chimney Crown Repair Is Failing
- Hairline cracks in the crown surface. This is the earliest and most common warning sign, and it’s caused by the thermal expansion and contraction of Woodland Hills’ summer-to-winter temperature swings. Water gets into those hairline fissures, then freezes and widens them during cold snaps. Hairline cracks are repairable; ignored cracks become structural damage.
- Spalling or crumbling concrete. If you can see small chunks of concrete in the gutter or on the ground near the chimney, the crown surface is actively breaking apart. This is what happens when moisture penetrates the crown and then heats up during a fire, creating internal steam pressure that blows off the top layer.
- Water stains on the ceiling or walls near the fireplace. This is the sign most Woodland Hills owners notice first, but it means the crown has been compromised for a while. The water is traveling down through the chimney system and into the home’s framing before it shows up on drywall.
- Rust streaks on the chimney pipe or chase top. The metal components under the crown are starting to corrode. If you see rust, the crown has already failed long enough to expose steel to moisture. We often find this on Ventis systems in Woodland Hills because the chase tops are exposed to coastal fog drift coming over the Santa Monica Mountains.
- Damp or musty firebox after rain. Run your hand along the inside of the firebox after a storm. If it feels damp or you smell wet ash, water is getting past the crown and running down the flue. This isn’t just a comfort issue; wetting and drying cycles accelerate the breakdown of the flue liner, which is why Olympia Chimney crown failures tend to become liner failures if they go unaddressed.
Replacement Cost & What’s Included
In Woodland Hills, a full Olympia Chimney crown rebuild runs $395 – $685 installed. The lower end covers a poured crown on smaller Ventis or Champion systems with minimal damage to the original mortar bed. The upper end covers larger chase openings or systems where the original crown was so compromised that we’re also rebuilding the masonry wash underneath it. If the metal chase top itself is rusted, we’ll quote that separately so you know exactly what you’re approving before we order parts.
Here’s what every crown repair includes:
- Crown form removal and surface prep (grinding away loose concrete, cleaning the surface for a proper bond).
- A new pour using UV-resistant, polymer-modified mortar that handles Woodland Hills’ temperature swings without cracking.
- Proper slope and drip edge so water runs off instead of pooling.
- Written price before we start. No surprise charges at the door.
- Written guarantee on the work, plus a free second visit if the repair fails within 365 days under our Done Right Promise.
You’ll get photos of the crown before, during, and after, and we’ll send over a digital invoice you can pay from your phone. That’s the Relay Visibility Guarantee, and it’s standard on every job, not an add-on.

You can absolutely inspect your own crown from the ground with a pair of binoculars. Look for the hairline cracks and spalling we listed above. You can also shine a flashlight from inside the firebox up toward the flue to check for water staining. What you shouldn’t do is climb onto the roof and try to patch a crown with a $12 tube of caulk. The crown sits at the very top of the chimney, usually at the highest point of the house, and in Woodland Hills that often means a two-story climb with a nasty wind blowing through the pass. Slips on a tile roof are far more common than people realize, and we’d rather you watched from the ground.
The other reason to skip the DIY route: surface sealants don’t fix a crown that’s already spalling or cracking down to the structural layer. You’d be covering up a problem that’s actively getting worse underneath. If you’re seeing more than a couple of hairline cracks, call us at (559) 249-1347 and we’ll give you an honest read on whether this is a sealant job or a full rebuild before anyone gets on a ladder.
FAQs
A properly poured crown using polymer-modified mortar typically lasts 15 – 20 years in Woodland Hills, assuming the original chimney structure is sound. If the crown is sitting on a deteriorated masonry base, no crown pour will last more than 5 – 7 years until that base is rebuilt. We’ll tell you which situation you’re in before we quote, and Cory Mitchell’s rule is simple: he’d rather show you the problem on your phone screen than hand you a bill you don’t understand. Call (559) 249-1347 and we’ll walk you through it.
Yes, if the cracking is limited to hairline surface fissures and there’s no spalling or crumbling, we can often seal the crown in place instead of rebuilding it. That repair typically runs $195 – $295 in Woodland Hills. But if we see chunks missing or water damage below the crown line, we’ll tell you point-blank that sealing will buy you a season at best.
Most Olympia Chimney crown rebuilds take 2 – 4 hours on site. The original crown is already failed, so we’re not spending time breaking up well-adhered concrete; we’re removing the loose material, prepping the surface, pouring the new crown, and letting it set. We schedule crown work for dry weather, and in Woodland Hills that usually means a clear morning with the sun doing us a favor by the afternoon.
We stock the common Olympia Chimney crown forms, mortar, and sealants on our trucks, so most Woodland Hills jobs are done same-visit. If your chase has an unusual size we’ll special-order the form, but rare is a rare enough word in this trade that we can count on one hand how often that happens. Call (559) 249-1347 and we’ll confirm the plan before you book.
