More living space — without adding on.
Dig out your basement and gain the ceiling height you need for a real family room, rental unit, or in-law suite. Engineered lowering, underpinning, and full waterproofing — with written estimates and a workmanship warranty.
Stop storing boxes in space you could be living in
Boston's older homes have great bones but low, dark cellars. A dig out unlocks square footage you already own — at a fraction of the cost of an addition.
- Ceilings under 7 feet — space you can't legally finish
- A cramped cellar with wasted potential
- Growing family, no room to add on
- Hunched-over laundry and mechanical rooms
- Damp, musty lower level nobody wants to use
- Need rental income or in-law space but no lot to build on
Dig out services built for Greater Boston homes
Every home and foundation is different. We match the structural method to your house — never the other way around.
Full Basement Lowering
Complete excavation of the basement floor to add 1–3+ feet of ceiling height, engineered and permitted for lasting structural integrity.
Foundation Underpinning
Section-by-section extension of your foundation walls downward, preserving full floor area while reaching new structural depth.
Bench Footing Systems
A faster, budget-friendly lowering method with reinforced concrete benching along foundation walls — ideal for many Boston triple-deckers.
Crawl Space Conversion
Dig out shallow crawl spaces and turn them into full-height storage or mechanical rooms, adding usable square footage you already own.
Drainage & Waterproofing Integration
Every dig out includes proper under-slab drainage, sump systems, and vapor protection so your new lower level stays permanently dry.
Egress Windows & Access
Code-required egress windows, window wells, and stair reconfiguration so your new lower level is safe, legal, and livable.

Basement dig out questions, answered
A dig out (also called basement lowering) excavates the soil floor of your basement to increase ceiling height — often from under 7 feet to 8, 9, or more. It turns an unusable, cramped cellar into true finished living space without adding on to your home.
