Basement Waterproofing Cost

A waterproofing quote should explain where water is entering and what the proposed work is meant to address.

Price note: this is a guide to comparing quotes, not a current price survey. Ask a provider for a written price for your location and needs.

What should the quote include?

Ask about inspection, drainage, sealing, pumps and making good disturbed areas.

Which charges need a closer look?

Check excavation, electrical work, discharge arrangements and ongoing maintenance.

Have the provider mark each item as included, optional or charged separately. An item left blank is a question to resolve, not something to count as free.

Before you decide

Compare the proposed approach and warranty exclusions. Do not treat every damp patch as the same problem or assume one product fixes all causes of moisture.

Compare the total you would pay

Put the offers side by side using the same work, dates and quantities. Add required extras and applicable taxes to each starting price. Keep optional upgrades separate so you can choose them deliberately.

  • For an hourly price: ask about minimum time, the expected hours and approval before the bill grows.
  • For a package: ask about its limits, expiry and the price of work outside it.
  • For a deposit: confirm whether it counts toward the total, when the balance is due and what happens if you cancel.

Keep the agreed price and work list together. If the plan changes, ask for the revised total before agreeing to the extra work.
