Boston's humid continental climate moderated by the Atlantic creates constant moisture cycling that turns wildlife chew holes into rot and mold problems inside Beacon Hill brownstones and Back Bay row houses. We assess rooflines, cornice returns, and masonry gaps where squirrels and raccoons exploit the freeze-thaw cycle, then replace compromised sheathing and flashing with exterior-grade plywood and copper step flashing rated for coastal exposure.
Historic structures in the North End and Charlestown often have original lath-and-plaster that must be preserved; we use breathable vapor-open membranes and lime-based insulation patches rather than closed-cell foam that traps moisture against 200-year-old timbers. All work follows Massachusetts wildlife handling rules that prohibit disturbance of protected bat colonies between May and August, requiring us to schedule exclusion and repair outside those windows.
South End and South Boston triple-deckers frequently suffer repeated raccoon damage at shared soffits and party walls; our process includes installing 1/4-inch galvanized hardware cloth behind new trim and sealing with elastomeric caulk that holds up to the salt air coming off Boston Harbor. Every job includes a written report noting any active nesting or denning so owners can coordinate with state wildlife officials if needed.
We carry the proper permits for work in Suffolk County conservation districts and always photograph before-and-after conditions at landmarks-adjacent properties such as those near the Freedom Trail or Boston Public Garden to satisfy both owners and insurance adjusters.

How it works
- 1
Site Inspection
We examine all potential entry points from the roof to the foundation, noting active sign and any protected species presence before quoting.
- 2
Animal Removal Coordination
Live trapping or one-way doors are set only after confirming no dependent young remain inside the structure.
- 3
Structural Repair
Damaged sheathing, flashing and insulation are replaced with materials selected for Boston's salt air and freeze-thaw conditions.
- 4
Final Sealing and Follow-Up
All openings are secured with metal mesh and caulk; a 30-day re-inspection confirms no new activity before final sign-off.
Pricing
Upfront written quotes after on-site inspection; final price depends on extent of hidden damage and access difficulty in historic buildings.
