How to prepare your block before you ask for a pool quote

Day one: measure access at its worst point

Do this first, before anything else, because it decides more of the price than the pool does.

Walk the route machinery would take from the street to the pool area and find the narrowest point. Measure it there, not at the gate. The tightest spot is usually not the gate at all — it is the gap between a downpipe and a fence, the width between a meter box and a wall, or the point where an eave overhangs a side path.

Measure the width at ground level and the overhead clearance along the whole route. Note anything that cannot move: a slab, a retaining wall, a mature tree, an air-conditioning unit on a bracket.

Why it matters in dollars: if an excavator can reach the pool area, the spoil goes out the same way and the job is conventional. If it cannot, the pool is craned in over the house, and the crane, the traffic management and the additional handling are a different order of cost. A builder who has to guess which of those applies will either quote the safe one and lose to someone who guessed low, or quote the low one and vary you later.

Write the number down. “1,050mm at the tightest point, between the downpipe and the fence, with 2.4m clearance under the eave” is a sentence that changes a quote.

The four photographs, and the one video

Photographs let a builder do half the site visit before they arrive, which means the visit is spent on the questions that matter.

Four corners. Stand at each corner of the yard and photograph back across it, so the whole proposed pool area appears from four angles. Include the house and the boundaries in frame.

The access route, end to end. One photograph at the street, one at the narrowest point with your tape measure held across it and readable, and one looking back from the pool area toward the street.

Anything unusual. A retaining wall, an easement marker, a septic lid, a pump, a large tree, an obvious rock outcrop, a neighbouring structure close to the boundary.

One video. Walk from the street to the pool area filming as you go, narrating what things are. Thirty seconds of that conveys more than a dozen stills, and it is the single most useful thing you can send a builder before they visit.

Send the same pack to every builder. That is the whole point — three quotes are only comparable if they were produced from the same information. Our guide to comparing pool quotes covers what to do with them once they arrive.

The three facts that are not in your backyard

Some of the information that moves a quote most is not visible on site at all.

Where the sewer runs. Order the sewer service diagram for your lot from your water authority. A sewer main crossing the proposed pool footprint is one of the few things that can stop a design outright or add a build-over approval and significant cost. Finding it now is free; finding it after excavation is not.

Whether a soil report already exists. If the house is reasonably modern, a soil classification was almost certainly done for the slab and may be in your building file or with the original builder. It will not always be sufficient for the pool — site class is determined per block and an excavation asks a different question of it — but knowing the class saves a conversation. See do you need a soil test before building a pool.

Which approval pathway your block is on. Flood-planning land, heritage overlays, easements, bushfire mapping and acid sulfate soils each push a pool off the fast track, and they are all mapped. Fifteen minutes on your council's planning portal will tell you, and it changes both the timeline and the documents you need. Start with do you need council approval for a pool and how long approval takes.

In parts of the Hunter, Lake Macquarie and the Central Coast there is a fourth: the mine subsidence guideline assigned to your address, which can cap the pool at 8 or 12 metres and rule out a wet edge entirely. Check it before you commission a design, not after — building a pool in a mine subsidence district explains what each guideline permits.

What finished looks like

You are ready to ask for quotes when you can send a builder one message containing all of this:

Postcode. Narrowest access width and overhead clearance, with the location of the tight point named. Fall across the pool area. Preferred pool size and type, or a note that you are open. Distance from the proposed pool to the house and to each boundary. Whether a soil report exists. Whether fencing, paving and landscaping are in scope. Your timing. The four photographs and the walk-through video.

That is the finish state. It takes about forty minutes and it converts three quotes that cannot be compared into three that can.

One thing it does not do: commit you to anything. Quotes are free, there is no obligation, and a builder who treats a well-prepared enquiry as a reason to push for a decision is telling you something useful. How to get free pool quotes covers what a quote must contain to be worth comparing, and what to ask a builder covers the site visit itself.
