Dampness after heavy rain
Record which wall gets wet and whether water appears during rain or afterward. Include photos taken from a safe, accessible area.
Where does the wall get wet?
Water near a wall connection
Tell us whether the issue appears at a crack, an opening, or where a wall meets the floor. These observations help explain the problem.
Limited exterior access
Mention adjoining buildings, paved areas, steps, or landscaping beside the affected wall. Access can materially change the scope.
Plan around the existing foundation.
Foundation waterproofing is not simply choosing a product. The proposed work should describe the affected wall area, preparation, treatment of vulnerable details, and any access or reinstatement needed. Share previous repairs and any available information about the building.
Exterior access matters
Discuss whether the relevant wall can be reached from outside and what surrounds it. Excavation or drainage work should be specifically included in the agreed scope if needed, rather than assumed.
Separate the water issue from structural concerns
Water entry and foundation movement are different concerns. Mention changing cracks or other visible movement so the appropriate assessment can be discussed before work is planned.
What affects the cost?
An estimate should reflect the actual area and work proposed for your property. Useful points to discuss include:
- Access to the work
- Height, nearby structures, and any finishes or obstructions around the affected area.
- Preparation and repairs
- What must be cleaned, removed, or repaired before a treatment can be applied.
- Scope and materials
- The area being treated, specified materials, and any work needed to restore disturbed surfaces.

Foundation Waterproofing questions
Do foundation walls need waterproofing?
Protection depends on the building and exposure. Recurring water entry is a reason to assess the wall and nearby conditions. A specific recommendation requires information about the existing construction.
What is the best waterproofing method for foundation walls?
The appropriate method depends on wall material, condition, water exposure, and access. Compare a proposed system by how it addresses your property’s conditions, not just its product name.
How do you plan foundation waterproofing correctly?
Identify the affected area, discuss the likely water source and wall condition, and establish what can be accessed. The written proposal should make preparation, treatment, and any reinstatement clear.
Can foundation waterproofing be done from inside?
Interior and exterior approaches address different conditions. An interior treatment is not automatically equivalent to protecting the outside wall. Ask what the proposed work will address and what its limitations are.
