A chase cover is used for a pre-fab or factory-built fireplace. Unlike a chimney cap that covers only the top of the flue opening, a chase cover fits over the top of the chimney. They’re also called “top pans” because they top chimneys that are sided with vinyl, metal, or wood. They are a common cause of rust stains on the chimney if installed incorrectly.
Chimney chase covers have many functions. These include:
- Preventing moisture in the chimney and flue;
- Protection from outside elements;
- Protection of the chimney liner;
- Aids in directing the smoke and burning embers away from your roof to prevent a house fire.
We offer galvanized, stainless steel, powder coated and copper chase covers.
Many times confused with the chase cover, the chimney cap is installed onto the chase cover in the same way as with a chimney crown on a masonry chimney.
Without a chimney cap, rain and snow can fall directly into your chimney. The moisture this creates will eventually corrode or warp the damper, which could cause a carbon monoxide risk if you continue to use your fireplace.
The chimney cap also prevents animals from nesting inside the chimney flue.
The chimney crown is a vital part of your chimney system. The crown circles the top of the chimney and acts an umbrella that’s intended to protect it from water damage. If your crown is cracked or damaged, moisture can seep into the masonry material and start deteriorating your chimney from the inside out.
Crown coat, for chimney top repairs, protects damaged chimney crowns by eliminating chimney leaks, and water penetration & absorption. The chimney crown coat will also protect the brick and mortar joints beneath from water entry.
If you believe your chimney crown needs attention, call us. We will send a CSIA Certified Chimney Sweep Technician to inspect the crown and determine the best course of action.
Repointing removes damaged mortar joints and renews them, while Tuckpointing fills in mortar joints of brickwork.
Repointing a chimney requires expert masonry skills. Our experienced masons will remove mortar and joints, correct mortar, repair damage, and use a waterproof seal to protect your chimney’s future.

All chimneys require periodic maintenance despite how they are constructed. Common chimney materials are aluminum, galvanized, stainless steel, & masonry which all have a life span of 5 to 30 years, pending the application and environment they are in.
If you’ve noticed any discoloration throughout the chimney brick or stone, particularly in the upper portion, you might want it checked out. Stains can really tell a lot about what’s going on inside and outside of a chimney, so pay attention to them and let them speak to you.
If you’re concerned your chimney is leaking, you may need to waterproof your chimney. This is done in a variety of ways depending on the need, including a new chimney cap, replace the flashing or repair mortar joints.
Flashing is the sheet metal that seals out water where your chimney meets or passes through the roof. Defective mortar joints or the use of improper mortar or brick can increase the tendency to absorb and convey water to the interior of the masonry chimney.
At Allegiance Chimney, we use WaterTite, a product that provides excellent water repellency to reduce cracking, spalling, freeze/thaw damage, chemical degradation, biological growth, efflorescence, and dirt pickup, thereby lengthening substrate life and reducing maintenance costs.

Sometimes chimney damage goes further than repairs. If your chimney has been neglected for years, you might want to consider Rebuilding your chimney. In some instances, your chimney might be unsafe to use unless it is rebuilt.
