Stop the rodents first, then fix what they broke.
Repairs done while rodents are still active get chewed again. New insulation gets shredded for nests, and a patched soffit gets a new hole beside the old one. So the order matters: find the entry points, remove the animals, close the gaps, and only then repair the damage.
If you are not sure whether the problem is active, start with rodent inspection. It tells us what is still going on and which damage is old, so you do not pay to repair the same spot twice. We also note what looks recent and what looks long settled, which helps if a contractor asks about the history.
What rodents do to an attic and its ducts.
In many older homes, attics are low and tight, with insulation laid between joists and ducts running through the same space. Rodents nest in that insulation, tunnel through it and tear at the duct wrap.
Damaged duct insulation and flex duct can leak conditioned air into the attic, and soiled insulation may need replacing. If you notice uneven heating or cooling in an upstairs room, mention it when you call. It can point to a chewed or crushed duct.
Wiring: a fire risk that goes to an electrician.
Rodents chew wire insulation, and exposed or damaged wiring can contribute to a fire. This is the one repair we do not touch. In New Jersey, electrical repairs must be done by a licensed electrical contractor, so we flag any chewed wiring we find and tell you which areas to have checked, so the electrician knows where to start.
If you see gnawed cable, flickering lights, a burning smell or a tripped breaker that will not stay reset, turn off the affected circuit if you can do so safely and call an electrician right away. Then call us so the rodents are dealt with at the same time.
We flag chewed wiring for the right trade. We never repair it ourselves.
Damage type, next step and who does it.
Not every repair belongs to us, and some belong to no one until the rodents are gone. This table shows how we sort the common cases.
| Damage type | What to do | Who does it |
|---|---|---|
| Attic insulation nested in or soiled | Remove soiled material, then reinstall or replace | We handle cleanup; see attic and crawl space cleanup. |
| Chewed ductwork | Seal or replace damaged sections after cleanup | HVAC contractor. |
| Chewed wiring | Turn off the circuit if safe, and have it inspected | Licensed electrical contractor. |
| Gnawed water pipe or supply line | Shut off water, then repair or replace the section | Plumber. |
| Fascia or soffit openings | Close with metal or hardware cloth, then repair trim | We seal; a carpenter refinishes. |
| Drywall holes and gnawed corners | Patch after the wall is sealed and clean | Drywall or general contractor. |
Not sure this matches what you are seeing? Describe it on the call and we will help you sort it out.
Call (888) 686-4821Openings at the roofline and pipes.
Rodents find the same weak points again and again: a gap where fascia meets soffit, a loose vent screen, or an opening around a pipe. Mice need only about a quarter inch, and rats about half an inch. A gnawed edge can grow into a doorway. Photos of each opening before sealing give you a record of the work.
We close openings with materials rodents cannot chew, such as hardware cloth, sheet metal and mortar, and we explain the full approach in rodent exclusion. Foam or steel wool alone gets chewed out or pulled away, so we do not rely on them.
Pipes, drywall and the damage you find later.
Rodents gnaw on plastic supply lines and drain pipes, usually where they run through a wall or under a sink. A small chew can leak slowly for weeks, so look for stains, swelling cabinet bases and a musty smell. If you find one, shut off the water to that fixture and call a plumber.
Drywall damage is often cosmetic: ragged holes at baseboards, gnawed corners and torn edges around pipes. It is also a map. A hole shows where they travel, and we use it to trace runs back to the entry point. Patch the wall only after that route is sealed, or the patch just moves the problem along.
Does insurance pay for rodent damage?
Often it does not. Standard homeowners policies commonly exclude damage caused by rodents and vermin. Look for the vermin or pest exclusion in your policy, or ask your agent, before you plan around a claim, and ask whether any related loss, such as damage from a fire, is treated differently.
We can describe what we found in plain terms, and you can pass that on. We do not tell you what your policy covers, since that is between you and your insurer. Keep photos of damage before anything is removed, and note the date you first saw it.
