FAQ
Straight answers, no fine print.
If your question isn't answered here, give us a call — we're happy to talk it through.
How do I get a quote?+
Send through an enquiry via our contact form or give us a call. For most projects we'll come out for a free site visit before quoting — it's the only way to price the work honestly.
How much does an earthworks or drainage project cost?+
It genuinely depends on the ground, the access and the scope. Rather than pretend to give a number online, we quote every job individually based on a real site visit.
How long will my project take?+
Small drainage callouts are often one to three days. A residential earthworks and drainage package might be one to three weeks. Larger civils runs longer — but we'll give you a realistic programme up front.
Do you work with builders and developers?+
Yes, a big portion of our work is repeat commercial and developer work. We're comfortable working to engineered drawings and reporting to project managers.
Do you handle council paperwork?+
For drainage connections, engineered retaining walls and civils packages, we manage the council approvals, inspections and as-built documentation.
What areas do you cover?+
Auckland, Hamilton, Huntly, Te Kauwhata and the wider Waikato. If you're outside that region, get in touch anyway — for larger jobs we sometimes travel further.
Do you clean up after the job?+
Always. Every site is left tidy, spoils removed, and access reinstated. It's a non-negotiable part of how we work.
How far in advance should I book?+
Small jobs — usually one to three weeks. Larger earthworks and civils — four to eight weeks, sometimes more in busy periods. Get in touch early to lock in your timeline.
