Planning
Do I need an engineer?
Yes. Underpinning changes how the house is supported, so engineered drawings come first and permits follow before excavation.
Will my neighbours be affected?
Semis and rowhouses share foundation walls. We review the neighbouring conditions and plan the sequence to protect them.
Can every basement be lowered?
Not always. Soil, groundwater, foundation type and lot access decide it, which is why the first step is a site review.
Who handles the permit?
We coordinate the permit and inspections as part of the scope.
During construction
Do I have to leave the house?
Often not for the whole job. Noise, dust, vibration and utility interruptions are real, and we discuss which phases are best spent elsewhere.
Will water be a problem?
Drainage and waterproofing are planned as part of the same project, not left for later.
How is the work staged?
The foundation is deepened in sequenced sections, never all at once.
Afterwards
Can the new space be finished?
Yes. We design and build the finished lower level, including renovations and, where the property allows, a legal basement apartment.
Do you give prices on the phone?
No. We do not give a figure without reviewing the house. A written scope follows the site review.
What records do I keep?
Drawings, permits, inspection records and the written scope.
