Chimney Caps, Crowns & Chase Covers

Nearly every expensive chimney problem starts the same way: water getting in from the top. The cap, crown, and chase cover are your chimney’s armor — inexpensive parts that prevent very expensive damage.

The top-of-chimney system

  • Chimney cap — a stainless steel guard that keeps out rain, squirrels, birds and raccoons while its spark screen protects your roof
  • Crown — the concrete slab that sheds water away from the flue; cracks here funnel water straight into the masonry core
  • Chase cover — the metal lid on factory-built/prefab chimneys; rusted-through covers are a leading cause of prefab leaks
The cost of waiting: An uncapped flue drinks hundreds of gallons of rain a year. The cheapest part on the chimney prevents the most expensive damage.

Fast, high-value fixes

Cap installation is often same-visit. Crown repairs range from flexible sealant coatings for minor cracking to full recasting with a proper drip edge. We stock common cap sizes and custom-order the rest — always in stainless, never the big-box galvanized ones that rust in three winters.

Frequently Asked Questions

Do I really need a chimney cap?

Yes — it’s the cheapest insurance a chimney can have. An uncapped flue takes in hundreds of gallons of water per year, plus whatever wildlife is looking for a warm home.

What’s the difference between a crown and a cap?

The crown is the concrete top surface of the masonry itself; the cap is the metal cover over the flue opening. Both need to be intact to keep water out.

Why is my prefab chimney leaking?

Nine times out of ten: a rusted chase cover. Replacing it with stainless steel solves it permanently.
