The detail
What a good waterproofing quote includes
A good quote spells out how the job is priced and what's covered — labour, materials, prep and clean-up — so you're comparing like for like. Check what each waterproofer's quote covers before you choose.
Worth knowing: getting two or three quotes is the simplest way to land a fair price — and it costs you nothing.
Licence number. On the quote, and verify it before work starts.
Compliance certificate. An AS 3740 certificate promised before tiling starts.
Membrane brand. The exact membrane product, not just 'waterproofing'.
Substrate preparation. Grinding, priming and levelling, so nothing is skipped.
Number of coats. Liquid membranes need at least two coats.
Flood testing. A 24-hour flood test before the tiles go on.

Local conditions
Things that can impact your job
These factors affect waterproofing work in this area — worth discussing with your tradie.
Seasonal Rainfall
Penrith gets moderate rainfall, so timing matters for exterior waterproofer work. Targeting the drier months gives the best run of uninterrupted days.
Cooler Months Give Better Results
Summers in Penrith are warm enough to affect exterior waterproofer work — materials can dry or cure too quickly on the hottest days. Your tradie will plan their work around the temperature — prep and shade-side work in the heat, application when conditions are right.
Winter Frost
Penrith gets light winter frosts — worth getting any exposed pipes insulated before the cold months hit.
Apartment Mix
Penrith has a significant proportion of apartments and units. If you're in a strata building, check whether body corporate approval is needed before waterproofer work begins — especially for anything affecting common property or shared services.
Check Your Lease Before Booking
Over half of properties in Penrith are rentals. If you're a tenant, check your lease before booking waterproofer work — some jobs need landlord approval. End-of-lease services are in high demand here, so book well ahead.

Your Penrith waterproofing checklist

- Check strata by-laws if in an apartment or unit
- Check lease requirements before booking if renting
