Repair is the last stage, not the first.
Gnawed materials look urgent, and it is tempting to fix them right away. But if the animals are still inside or an entry is still open, new materials will be chewed too. For that reason repair follows removal, sealing and cleanup.
Once the structure is clear, the technician returns to see what the animals ruined. The estimate lists each item: the material, the area and the cost.
Commonly affected materials.
- Attic insulation: nested in, compacted or stained by urine.
- Flexible ductwork: chewed holes or torn insulation sleeves.
- Vent and soffit screens: bent, torn or pushed aside.
- Drywall: gnawed edges or holes created for passage.
- Wire sheathing: chewed insulation that exposes copper.
Damaged wire calls for caution. Exposed copper can start a fire or shock someone, so keep your hands off. We mark it for a licensed electrician.
How repairs are scoped.
| Item. | Repair. | Notes. |
|---|---|---|
| Insulation. | Remove soiled sections, install new batts or blown-in. | Match the existing type and rating. |
| Flexible duct. | Replace damaged length and reseal joints. | Keeps airflow and conditioned air. |
| Vent screens. | Install metal mesh and secure with screws. | Doubles as exclusion. |
| Drywall. | Patch or replace gnawed sections. | Texture and paint are separate trades. |
| Wiring. | Flag for an electrician. | Safety first. |
The estimate keeps these lines separate. Skipping a line does not affect the others.
Repairs and the rest of the job.
The sanitizing page explains how contaminated material is removed before repair. The sealing page explains how entries are closed. Together with trapping, those stages form a sequence that protects the repair from repeating.
Houses beside hillsides or planted slopes might see more wildlife, though we hold no survey of which ones. Say so if your lot adjoins open ground, as that affects how much metal the sealing needs.
Documenting damage.
Take photographs before anything is removed and keep them with the written estimate. If you file an insurance claim, those records help. Ask your insurer whether rodent damage is covered, and what documentation they need.
Dust control before you touch anything.
This is not medical advice. It is a short list of precautions that public health pages suggest for homes showing rodent signs.
- Pellets and nests turn to powder when dry, so no broom and no shop vac.
- Open every window you can reach, then step outside for a half hour.
- Gloves go on first, come off last and end up in the trash bag.
- Spray, wait, then lift the wet mess with a towel in one motion.
- Seal towels, gloves and waste in a bag, then drop that bag into a second one before disposal.
- Washing is the final step, whether or not you wore gloves.
