Tradie Talk Translator: Your Guide to Building & Renovation Lingo

When you start a build or renovation, it can feel like your tradie is speaking another language. We promise they’re not trying to confuse you — it’s just the way the industry talks.

Here’s our no-nonsense guide to common terms you’ll hear on-site or in your contract, so you can follow along with confidence.

Contract & Budget Terms

Provisional Sum

An estimate for work where the exact details aren’t confirmed yet (e.g. landscaping, rock removal). The final price is updated once the job is complete.

Prime Cost (PC) Item

An allowance for a specific product not yet selected (e.g. oven, tapware). The price changes depending on what you choose.

Variation

Any change to the agreed scope of work. Variations may affect your budget or timeline, and always require written approval.

Contingency

A budget buffer for unexpected surprises — not always included unless specified.

Fixed-Price Contract

Your build price is set, but PC items and provisional sums can still shift the final figure depending on selections and conditions.

On-Site Stages & Trades

Rough-In

Plumbing and electrical services are installed inside the walls before plasterboard goes on.

Fit-Off

The finishing stage where fixtures, tapware, light fittings, handles, and appliances are installed.

Frame Stage

The skeleton of your home is up — walls, roof lines, and layout start taking shape.

Lock-Up

Cladding, external doors, and windows are installed so the home is weatherproof.

Chippie / Sparkie / Brickie

Nicknames for carpenter, electrician, and bricklayer.

Queenslander & Heritage Features

VJ Boards (Vertical Join)

Timber wall-lining panels commonly found in Queenslanders and easy to replicate in modern renovations.

Breezeways

Decorative panels above doors that promote airflow and add character.

Bullnose Verandah

A curved corrugated-iron verandah roof — quintessentially Queenslander.

Casement Windows

Timber windows hinged on the side, opening outward like doors.

Stumps

Vertical posts supporting a Queenslander, providing airflow and flood protection.

Finishes & Details

Square Set

A clean, modern finish where walls meet ceilings without cornice.

Mitred Edge

A crisp angled corner join, often used in stone benchtops or tiled edges.

Shadowline

A recessed gap between surfaces for a sleek, contemporary look.

Soft Close

Cabinetry hinges or runners that close smoothly and quietly.

Two-Pack (2PAC)

A durable, high-quality painted finish for cabinetry.

Site Banter (The Fun Bits)

Smoko

The morning tea break — name sticks, even if no one’s actually smoking.

She’ll Be Right

“It’ll probably be fine” — but best to double-check what’s meant!

The Boss

Usually the foreman… unless the real boss (you) walks on site.

At Hill House Design & Construct, we translate the jargon into plain English so you feel informed and confident every step of the way. And if you ever hear a term you’re unsure about — just ask.
