Websites built as
solid as your work.
Onyx Agency designs and builds custom websites for builders, plumbers, electricians, carpenters and trades businesses — fast, mobile-first sites that turn local searches into quote requests and booked jobs. Built with precision, designed to win work.
A studio standard,
not a template.
Loads before they scroll away
Sub-second loads on every device. Site managers and homeowners on the move never bounce waiting for a render — they find you and call, fast.
Built to win quotes
Every section is mapped to a job — quote requests, service calls, booked work. We design paths that turn visits into paying jobs, not just page views.
No templates, just your trade
No recycled layouts. Your business gets a bespoke site built to stand apart in your trade and your area — proof of work front and centre.
Built to grow with you
A future-proof foundation that grows with your crew, your fleet, and your workload — without rewrites as you take on bigger jobs.
Measured, not guessed
We instrument every page and refine against real enquiry data, so the leads keep compounding month after month.
A performance guarantee
If your new site doesn't outperform the old one, we keep working until it does. That's our standard — and our trade.
Standard vs. considered.
Drag the handle to see the difference.
From brief to launch.
Discovery & strategy
We map your services, your service area, and the jobs you actually want — so the site brings in the work that pays, not just clicks.
Design & build
A bespoke, fast site built mobile-first for tradies on the go — quote flows, clear service pages, and proof of work that earns the call.
Launch & refine
We ship, track the leads coming in, and refine against real enquiry data — so the work keeps coming long after launch.
Built for the trades.
A selection of sites we've built for builders, plumbers, electricians and haulage firms — each crafted to win more work.
Trusted by builders & trades.
"Onyx rebuilt our site and the phone hasn't stopped. The committees that commission our builds now see scale and safety record before they even call — we're winning tenders we used to lose on reputation alone."
"We ran Sydney's civil haulage for years but had nothing online to show for it. Onyx built a fleet-led site that wins recurring contract work instead of one-off phone jobs — the difference has been night and day."
"Our reputation was built on the tools but invisible online. Onyx turned local searches into booked service calls — emergency bookings especially. Stressed homeowners now find help and call us first."
