What rodents damage.
A rodent's front teeth grow without stopping, and gnawing is how the animal keeps them short. Soft materials such as insulation, duct wrap, cardboard and plastic are easy targets. Wires, pipes and wood can also be chewed, and some of that damage is a safety issue.
The signs include shredded insulation, ragged edges on duct wrap, holes in screens and small bites in wood. Sometimes the first sign is a short circuit or a draft you cannot explain.
How we document and scope.
Before anything is replaced, we photograph each damaged area and list what we see. That record helps you talk to an insurance agent if you choose to, and it lets us give you a clear scope.
- Insulation: batts, loose fill and vapor barriers.
- Ducts: flex duct, duct wrap and connections.
- Screens and vent covers.
- Wallboard and trim near access holes.
- Wiring: identified, photographed and referred to an electrician.
The order of repair.
| Step. | What happens. | Why. |
|---|---|---|
| Trapping. | Animals removed. | So new materials are not chewed. |
| Sealing. | Entries closed. | So nothing returns. |
| Cleanup. | Waste and soiled material removed. | To prepare for new materials. |
| Repair. | Damaged items replaced. | To restore the building. |
Safety around chewed wiring.
Never touch a bare wire. If it is safe to do so, switch off that circuit at the breaker and phone an electrician. Rodent gnawing can strip insulation from wires, and the danger is real even when the wire looks harmless.
We note wiring damage and recommend the right tradesperson. We do not do electrical repairs.
Insurance and records.
Owners often ask whether insurance pays for rodent damage. Every policy differs, and what yours covers is something we cannot say. Most agents want photographs and a written damage list, and we supply both.
The CDC page linked below explains how to handle droppings safely, which matters during any repair that disturbs old waste.
Before you call, a quick health checklist
What follows restates advice from public health agencies. It suits any household, with or without a booked visit.
- Brooms and vacuums are the wrong tools, because both stir settled droppings into the air where you breathe them.
- A room sealed for weeks needs a cross draft and a half hour of patience first.
- Keep gloves on for the whole job, take them off with care, wash reusable pairs and then wash your hands.
- Keep spraying until nothing looks dry, then leave the room for a few minutes.
- Put used towels in a plastic bag along with any dead rodent, which you move with gloves or a tool and never with bare fingers.
- If illness follows contact with droppings, a physician is the right person to ask, and you should describe what you touched.
