Common Questions About Pricing
Why not list fixed prices?
Every roof’s different. We price after inspection so you get accuracy, not guesses.
What’s special about WaiSeal Pro?
Spray-applied and seamless no joins, no torching, fully bonded and rain-ready fast.
Can I rejuvenate instead of replace?
Often yes. If the structure’s sound, rejuvenation can restore waterproofing for 30–40% less.
Do you charge for assessments?
Not in Christchurch they’re free and obligation-free.
