The detail
What a good home building 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 builder'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.
Itemised scope. Every stage listed, site prep to finishing, not a lump sum.
Material specs. Exact brand, grade and quantity, not 'good quality'.
Exclusions. Driveways, landscaping, fencing and site costs are classic traps.
Prime cost and provisional sums. Allowances for choices and site work not priced yet.
Licence and insurance. ABN, licence, public liability and home warranty cover.
Permits. Who gets permits, soil tests and compliance certificates.

Things that can impact your job
These factors affect home building work in this area — worth discussing with your tradie.
Wind-Rated Construction
Mount Coolum is in an elevated wind area — enhanced tie-down fixings and wind-rated framing are standard for structural work here. Worth confirming the wind rating spec in your quote.
Shorter Lifespan on Exterior Finishes
Mount Coolum is right on the coast — exterior surfaces and finishes typically last 5–7 years here, compared to 10+ inland. Coastal-grade products aren't optional when salt air is this constant.
Moisture Management and Drier-Month Scheduling
Mount Coolum's warm, humid climate means moisture management matters for any exterior work. Good ventilation and moisture barriers prevent issues behind surfaces.
Book Early — Weather Windows Fill Fast
Mount Coolum gets significantly more rainfall than most of Australia — builder work needs to target the drier months. Book well ahead, because the good weather windows fill up fast.
Termite Risk — Timber
Termite activity is very high in Mount Coolum. All timber — cabinetry, joinery, framing, flooring — should be termite-treated or a naturally resistant species. Annual inspections are essential.
