What Is a Ducted Vacuum System Contractor?

A Ducted Vacuum System Contractor is a specialist technician who supplies and installs built-in central vacuum systems for residential homes. These systems include concealed piping installed throughout the house, with inlets in each room and a central vacuum unit usually located in a garage or utility space. For owner builders using the Build Buddy app, installing a ducted vacuum system during construction ensures a cleaner, quieter, and more efficient solution than portable vacuum cleaners.

What Does a Ducted Vacuum System Contractor Do?

Your Ducted Vacuum System Contractor will complete works according to your agreed scope of works.


Typically, a Ducted Vacuum System Contractor will:

  • Help you select a vacuum system appropriate for your home's size and layout
  • Supply the main vacuum unit and accessories (inlet valves, hoses, tools, etc.)
  • Install in-wall ducting during frame stage and return later to mount the unit and test the system
  • Coordinate with your builder or electrician if any power provisions or wall chases are needed
  • Test the system for suction power and correct operation of each inlet


This work is typically split into a rough-in (during framing) and a fit-off (after plastering and finishes).

Tip: Avoid Costly Rework

Ducted vacuum pipework must be installed during the frame stage — retrofitting it after plastering is expensive and invasive.


Make sure your contractor coordinates with your framer and electrician to avoid clashes with studs, wiring, or plumbing.


Ask if the quote includes both rough-in and final fit-off — some installers price these separately.



If you’re building two storeys, ensure the vacuum unit is powerful enough and that returns are balanced across both levels.

What Makes a Good Ducted Vacuum System Contractor?

A good Ducted Vacuum System Contractor will:

  • Be familiar with major ducted vacuum brands like Vacuum Maid, Hills, or Valet
  • Offer expert advice on inlet placement, motor sizing, and wall cavity requirements
  • Provide a clear quote outlining both stages of installation and all supplied components
  • Be flexible with timing — especially since installation is split across two phases
  • Offer warranty support and demonstrate how to use and maintain your system


They should also supply genuine accessories and recommend suitable cleaning tools for your flooring type.

Before You Begin: What You’ll Need Ready

To get quotes from Ducted Vacuum System Contractors, you’ll need:

  • A floorplan showing where you’d like inlets placed (usually one per 60–80m²)
  • Information on whether you have a single or double-storey build
  • Details on where you’d like the central unit located (garage, laundry, etc.)
  • Your build timeline, especially the estimated frame and lock-up stages
  • Power availability for the central unit (usually a standard GPO)

Average Timeframe

For this task, Pros typically provide quotes within 7-10 business days.

When Can I Expect Quotes?

Timeframes often vary based on demand and the type of Pro you're engaging (e.g. a plumber). If additional communication or clarification is needed is needed, the quoting process may take longer.

 

Don't be alarmed if you don't receive quotes or communication from any Build Buddy Pros straight away. Some work is more complex and the Pro may need time to comprehend your documents or scope of work. Depending on the job, there may even be some work required by the Pro before they are able to quote (e.g. a site visit might be required).

 

If the average timeframe indicated here has passed, and you have not received any messages or quotes, please feel free to contact the Build Buddy Expert Guidance and Support team for an update on quoting for this task.

Frequently Asked Questions

  • Can I install a ducted vacuum after the house is built?

    It’s possible but difficult — it involves cutting into walls. It’s much more cost-effective to install during the frame stage.

  • How many inlets do I need?

    Generally one inlet can cover around 60–80m². Most homes need 2–4 inlets depending on layout.

  • Where does the vacuumed dust go?

    Into a central unit — usually installed in the garage or laundry — that you empty every few months.

  • Is it noisy?

    No — most of the noise is isolated to the central unit. It’s quieter than a standard vacuum when in use.
