Before you say yes

Good questions to ask your waterblaster, and the warning signs to walk away from.

Questions to ask

  • What pressure do you use on my cladding, deck or roof, and have you done this surface before?
  • Is the price for the whole job, and does it include cleaning up and treating the surface after?
  • How do you stop water getting behind cladding, into windows or into the roof space?
  • Do you carry public liability insurance?
  • Can I see photos of similar jobs you have done?

Red flags

  • They want to use high pressure on timber cladding, soft roofing or old paint without testing a small spot first.
  • The price is a lot lower than other quotes and the quote does not say what is covered.
  • They cannot explain how they protect windows, vents and power outlets.
  • No insurance, or they will not show it.
  • They pressure you to book on the spot.
