Before you book an inspection
Which waterproofing system does my basement need?
The location and timing of the leak guide the recommendation. We inspect the wall–floor joint, visible cracks, sump equipment and outside drainage. Interior drainage, exterior waterproofing and crack injection address different water paths; we explain which fits your home.
What affects basement waterproofing cost in Kensington?
Drainage length, excavation depth, access, existing finishes, wall condition and the discharge route all affect the scope. We identify the problem, explain the repair, and give you a written price before we leave.
How long will the work take?
The schedule depends on the repair, access and site conditions. We explain the expected duration, areas that need to be opened and agreed restoration before starting.
Do I need a permit?
Permit needs depend on the proposed work and the property’s jurisdiction. We review this during planning and explain permit responsibilities in the written scope.
What warranty covers the work?
Interior waterproofing carries lifetime coverage; exterior waterproofing and crack injection carry 25-year coverage. The written warranty sets out the covered system, conditions and exclusions. Read our warranty terms →
