Thumping and walking sounds in the attic at night — heavy enough to sound almost human? November is when Chelsea's raccoons settle into winter dens, and an attic or chimney in one of Chelsea's triple-deckers is exactly the warm, dry shelter they're looking for. In a city this dense, a raccoon that finds your roofline has usually already tested half the street.

Harvey's Animal Evictions LLC is a licensed Massachusetts wildlife removal company based in Wilmington, with our shop in Medford. We humanely remove raccoons from Chelsea attics, chimneys, and walls, and seal the entry points so the next raccoon doesn't move into the same spot.

 Signs raccoons have moved in

​

• Thumping, walking, or slow scratching sounds in the attic or ceiling, mostly at night

• Chattering or growling from the chimney or wall voids

• Torn or pried soffits, roof vents, or chimney caps — raccoons are strong and pull building materials apart

• A raccoon seen on the roof at dusk, or using the same route onto the roof night after night

• Tipped trash barrels and scattered garbage — a sign raccoons are working the street, even before one gets in

• Droppings in the attic (raccoons use one spot as a latrine) and torn-up insulation

​

A raccoon inside isn't just noise. Raccoons are strong enough to tear ductwork, pull apart roof vents, and damage wiring, and they compress and soil insulation wherever they den. Raccoon droppings can carry parasites you don't want in the house. And a raccoon setting up in November is settling in for the whole winter.

Where Chelsea raccoons get in

​

Chelsea is one of the densest small cities in Massachusetts — triple-deckers and two-families packed street to street, from the waterfront and Mill Creek to the neighborhoods under the Tobin Bridge. Old rooflines, layered additions, and porches built onto houses over a century of work leave raccoons plenty of openings:

• Uncapped chimneys — a raccoon's favorite den: warm, vertical, and protected

• Roof returns and soffits — pried or rotted open where roof meets wall

• Roof and gable vents — pulled apart by an animal that works with its hands

• Gaps where additions, dormers, and porches meet the original house — every roofline change leaves small openings

• Utility lines, fences, and overhanging branches — the highway that gets them to the roof in the first place

 

From Mill Creek to the Tobin approaches, the pattern is the same: if a raccoon can reach your roofline, it is testing the weak spots — and in November it only needs one to work.

How we get them out — and keep them out

 

Every job starts with an inspection, which you can book online through our website. We don't give estimates over the phone or online, because the plan depends on what we find: the entry points, where they're denning, and how much sealing the house needs.

1. Inspection — We find every entry point, locate the denning area, and check the damage, then give you a clear plan and price before any work starts.

2. Humane removal — Raccoons are removed safely and humanely using live traps and, where the situation fits, one-way exclusion devices that let them leave but not get back in.

3. Exclusion and repairs — We seal entry points with durable materials a raccoon can't pry apart: chimney caps, vent covers, and soffit and roof-line repairs. Raccoons are strong, so the sealing has to be stronger than they are.

4. Cleanup — We can remove soiled insulation and nesting material and sanitize the space, including latrine areas.

Chelsea raccoon questions

 

How much does raccoon removal cost in Chelsea?

It depends on the entry points, how much damage there is, and how much exclusion work the house needs, so we never quote a price without looking. Every job starts with an inspection — book online through our website, and the inspection fee is confirmed at booking. After the inspection, you get a clear price before any work starts.

Once they're out, will more raccoons move in?

Not through the same holes. Other raccoons will test a house that's sheltered a den before — in a dense city like Chelsea there's always another raccoon on the street — which is why we seal every entry point we find, including the ones they're not using yet, with materials they can't pry apart.

It's a triple-decker and I rent — who books the inspection?

Usually the owner or property manager, since exclusion work changes the building. We work with Chelsea landlords and property managers regularly — if you're a tenant, send your landlord our way and we'll take it from there; if you're the owner, book the inspection online and we'll assess the whole roofline, not just one unit.

Do you handle other animals in Chelsea?

Yes — squirrels, bats, skunks, woodchucks, opossums, birds, and more, plus mole and vole lawn treatment. See the full list on our FAQ page.
