About Us
A family business, not a franchise.
BM Total Building is run by Aaron Griffiths and a small, steady team, not a call centre. We've been building across the Illawarra and Sutherland Shire for 25 years, and Aaron is still the one who walks your site, quotes your job and answers the phone.
How It Works
From your first call to handover day.
Tell us what you're planning
Reply online or call. We'll call you back within five minutes during business hours, not a week later.
01
Walk the site with Aaron
We look at the block or the existing home, talk through what's possible, and note what a real quote needs to cover.
02
Get a written, line by line quote
Site costs, PC items and allowances spelled out, not buried as provisional sums you discover later.
03
One team, start to finish
Regular updates while we build, a clean site every day, and a finished job that matches what was quoted.

What Clients Say
Twenty five years of word of mouth.
They turned up when they said they would, every day, and the finished renovation matched the quote exactly. No surprise variations at the end.
Sarah M.
Renovation, Thirroul
We got quotes from four builders. BM Total's was the only one that itemised site costs and PC items, and that's exactly how the job ran.
David & Priya K.
New Build, Helensburgh
Our deck was up in three weeks, the site was left clean every single day, and Aaron answered the phone himself every time we called.
Michael T.
Deck Build, Austinmer
Our roof was replaced after storm damage, and they handled the insurance paperwork for us. We didn't have to chase anyone.

Common Questions
What people ask before they call.
Will you blow the budget?
Every quote is fixed price and itemised line by line, including site costs, excavation and PC items. Nothing gets "clarified" as a variation once the job is underway.
Will the job finish on time?
One team runs the whole job, so you're not waiting on five separate trades to line up their schedules. You'll get regular updates through the build, not just at handover.
What areas do you service?
The Northern Illawarra and the Sutherland Shire, from Helensburgh and Stanwell Park down through Wollongong, and across to Cronulla and Sutherland. Full suburb list is below.
Are you actually licensed and insured for a job this size?
Yes. We're a licensed builder and covered under the NSW Home Building Compensation Fund, which is required by law for residential work over $20,000. Licence and HBCF details are in the footer of every page.
Do you only do small jobs?
No. We build everything from decks and re-roofs through to full custom new homes and knock down rebuilds, from $15,000 jobs up to $1.5M plus builds. Have a look through Our Work to see the range.
