A carport installer sets out, anchors and erects a free-standing or lean-to vehicle shelter. Most carport installations take one to two days on site: a single carport is usually up in a day, a double or triple in two, once the footings have been cast and allowed to cure. The installer is responsible for the structure standing square, draining properly and staying up in wind — not just for the sheeting looking straight.
What a carport installer actually does
The job is part measurement, part groundwork and part roofing. An installer surveys the driveway, decides where the posts can land, digs and casts the footings, erects the frame, fixes the roof sheeting and seals any junction against the house. Everything else — the quote, the drawings, the council question — hangs off those decisions.
- Survey the site — measure the driveway, check vehicle swing and door clearance, find the fall for water run-off.
- Check the ground — establish what the posts will be anchored into: concrete, paving, or soil needing excavated footings.
- Set out the structure — mark post centres square to the house or boundary.
- Cast the footings — excavate and fill, or bolt base plates to an existing slab.
- Erect the frame — stand the posts, then fit beams and purlins to line and level.
- Fix the roof sheeting — lay and fasten sheets to the correct fall so water runs off, not back.
- Flash and seal — where a lean-to meets the house wall, flashing is what stops the leak.
- Finish the rainwater path — fit gutters and downpipes where the run-off would otherwise undermine paving.
The carport installation process, step by step
| Stage | What happens | Typical time |
|---|---|---|
| Site visit and measure | Driveway measured, post positions and fall agreed, material chosen | Under an hour |
| Quote and sign-off | Fixed price confirmed against size, material and site access | 1–3 days |
| Footings | Holes excavated and cast, or base plates fixed to existing concrete | Half a day, plus curing |
| Frame erection | Posts stood, beams and purlins fitted square and level | Half a day |
| Roof sheeting | Sheets laid to fall and fastened; shade cloth tensioned on a shadeport | Half a day |
| Flashing and finishing | Wall junction sealed, gutters fitted, site cleared | A few hours |
Curing is the reason a two-day job is rarely a one-day job. Concrete footings need time before the frame loads them, so installers routinely cast on the first visit and erect on the second.
What an installer needs from you before starting
- Access — room to bring in posts, sheeting and a mixer. Narrow side passages and locked gates are the usual delay.
- A decision on size — how many vehicles, and whether you want walking room around the doors. See standard carport sizes in meters.
- A decision on material — shade net, steel, aluminium or timber, which drives both price and lifespan.
- Clarity on services — where water, electrical or irrigation lines run, so footings do not go through them.
- Approval, where it applies — some structures need plans submitted before work starts.
Questions worth asking a carport installer
- Is the quoted price supply and installation, or supply only?
- What is the structure anchored into, and how deep are the footings?
- Who submits plans if the structure needs approval?
- What happens to rainwater — is guttering included or extra?
- Is the steel galvanised, and is the fixing hardware corrosion-rated for a coastal site?
- What is covered if a panel or fixing fails after installation?
Installer or supplier-only: who does what
A supplier sells you the material. An installer is responsible for the structure once it is standing. That difference shows up in the price: a supply-only kit looks cheaper because footings, labour, flashing and rainwater work are not in it. Compare a kit price against an installed price before deciding — the gap is the work described above.

Frequently asked questions
How long does carport installation take?
One to two days on site for most domestic carports — a single in about a day, a double or triple in two — with footing curing time between the groundwork and the frame going up.
Do carport installers do the groundwork too?
Yes. Excavating and casting footings, or fixing base plates to an existing slab, is part of the installation. A quote that excludes groundwork is a supply-only quote.
Can a carport be installed on an existing concrete driveway?
Usually yes — posts are bolted to base plates fixed into the slab, provided the concrete is thick and sound enough to hold the anchors. The installer checks this at the site visit.
What is the difference between a carport installer and a builder?
A carport installer works to a known structural system — set spans, set post sizes, set sheeting — so the work is faster and priced per size. A builder is designing and pricing a one-off structure from scratch.
