About Us

Local Shed Builders You Can Trust

Based in Moonta, working across the York Peninsula and most of South Australia. We're a small, family-run operation that treats every job like our own backyard.

Our Story

30 Years on the Peninsula — Now Full Supply & Install

Trevarth Garages has been building quality sheds for the York Peninsula for over 30 years. What started as a trusted local shed supplier has grown into a full service operation — we now supply, deliver and install through our own erection crew, so customers get one point of contact from enquiry to handover.

We recently brought on YP Erect as our installation arm, meaning we can now handle the complete project: council approvals, site coordination, supply and erection. If you want a company that does it all, that's us now.

Most of our work still comes from referrals — builders, farmers, and families who've used us before and tell their mates. We're a small team and we plan to keep it that way. That means every customer gets someone who actually gives a damn about the job.

What We Stand For

The Way We Work

Four things we never compromise on — they're why our customers come back, and why their mates call us next.

Quality

If it's not square, level and plumb, it doesn't leave the site. Quality materials, quality workmanship.

Honesty

Honest quotes, honest timelines, honest advice. If a job's not right for us, we'll tell you straight.

Local

Born and bred Peninsula. Local materials, local sub-contractors, local economy — it all matters.

Reliable

We show up when we say we will. We finish when we say we will. No phantom tradie act.

Why Local

Country Service, Without the City Mark-Up

Big shed-building companies will quote you sight unseen, ship you a kit, and leave you to figure it out — or charge you a fortune to fly someone in.

We do it the old-fashioned way. We come to your place, talk through what you actually need, and price it fairly. Then we build it ourselves. No middlemen, no big overheads — just locals who know their trade.

When you go local, you keep the money in the community, you get a tradie who actually answers the phone, and you get someone who'll stand behind their work. We see our customers around town — we're not going anywhere.

"We treat every job like it's for a mate — because in a small town, it usually is."
