What kind of homes and basements does Boston have?

What causes basement and foundation problems in Boston?

Filled land and groundwater

In filled neighborhoods, falling groundwater can expose and rot wood pilings under older buildings, a structural issue for engineers.

Triple-decker stone foundations

Fieldstone and brick foundations leak through mortar and need repointing and drainage.

Coastal storm flooding

Low areas near the harbor can flood in nor'easters; sumps and backflow valves help.

Shared-building decisions

Condo associations must agree on basement work in multi-unit buildings.

What do Boston homeowners ask most?

What are wood pilings and why do they matter in Boston?

Some buildings on filled land rest on wood pilings that last only while submerged. If groundwater drops, they can rot and the building can settle; that needs a structural engineer.

What registration should a Boston contractor have?

Massachusetts Home Improvement Contractor registration for most residential work and a Construction Supervisor License for structural work.

Can a Boston triple-decker basement be made dry?

Usually dry enough for storage and mechanicals with repointing, interior drainage and dehumidification.
