Common rodent-related duct problems
Attic and crawlspace ductwork can be vulnerable when rodents travel along runs, nest nearby or use damaged insulation as material.
We look for
- Torn or missing outer insulation
- Punctures or holes in flexible duct
- Disconnected or loose runs
- Contamination near or on ductwork
- Sections that are crushed or physically damaged
- Nearby rodent entry points that should be addressed
Repair versus replacement
If damage is limited to the exterior insulation and the air-carrying duct remains intact, a repair may be possible. If the duct itself is compromised, a replacement run may be the more appropriate recommendation.
Scope can include
- Repairing exterior insulation damage
- Re-securing a loose or detached connection
- Replacing one or more duct runs
- Removing and disposing of damaged duct material
- Coordinating attic or crawlspace cleanup
Protect the repair from repeat rodent activity
Replacing ductwork without addressing active rodent entry can leave the new material exposed to the same problem. When rodent activity is part of the project, proofing should be considered alongside duct restoration.
A coordinated project may include
- Rodent proofing
- Trapping follow-up
- Duct repair or replacement
- Attic or crawlspace cleanup
- Insulation restoration when affected
