Things to consider before you book
The local conditions that shape the job, the best time of year to book, and what to sort out before you choose a waterproofer.
Keep Gutters Clear and Check Council Rules
Most of Hobsons Bay is classified as bushfire prone land — keeping gutters and roof valleys clear is especially important here. If your property is near bushland, check with council whether any specific requirements apply.
Coastal Conditions
Most of Hobsons Bay is close enough to the coast for salt air to be a factor on exterior surfaces. Coastal-grade products last noticeably longer than standard options here — worth specifying in your quote.
Seasonal Rainfall
Most of Hobsons Bay 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 most of Hobsons Bay 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
Most of Hobsons Bay gets light winter frosts — worth getting any exposed pipes insulated before the cold months hit.
Best time of year for exterior waterproofing in Hobsons Bay
Ideal months: November to April.

What's in a good Waterproofing quote?
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.
- 01Licence number
On the quote, and verify it before work starts.
- 02Compliance certificate
An AS 3740 certificate promised before tiling starts.
- 03Membrane brand
The exact membrane product, not just 'waterproofing'.
- 04Substrate preparation
Grinding, priming and levelling, so nothing is skipped.
- 05Number of coats
Liquid membranes need at least two coats.
- 06Flood testing
A 24-hour flood test before the tiles go on.
