- Signs of rot or deterioration
Inspection costs commonly range from:
$100 to $300
A proper inspection helps prevent unnecessary repairs by identifying the actual cause of damage.
2. Chimney Chase Cover Repair Cost
The chase cover is one of the most important parts of a chimney chase because it prevents water from entering the structure. If moisture reaches the fireplace system and affects its components, gas fireplace repair may be needed to address damage and restore proper operation.
Repair costs typically range from:
$300 to $800
Common chase cover problems include:
- Small cracks
- Rust spots
- Loose edges
- Poor sealing
- Improper water drainage
Minor issues may be repaired, but severely damaged covers often need replacement.

- Poor fit
Replacement costs commonly range from:
$600 to $1,500
The price depends on:
- Chase size
- Material used
- Custom fabrication requirements
- Installation difficulty
Stainless steel chase covers are often used because they resist corrosion and provide long-term protection.
