Where’s the job?

Scope of Works

• mark out pond and deck footprint and confirm levels

• excavate pond area to design depth with benches and remove spoil

• install underlay and heavy‑duty liner, seam/weld joins and pressure test for leaks

• fit pump, filter and overflow arrangements and advise on electrical connection needs

• remove existing decking boards and fixings, inspect and replace rotten joists and posts

• install new treated posts and joists to suitable depth, lay deck boards, cut edges and fit balustrades

• remove waste, tidy site and provide basic commissioning of pond equipment; use PPE and safe working‑at‑height measures

Typical Cost

Time on Site

Typical duration 1–5 days depending on size and complexity — small pond and partial deck replacement 1–2 days; larger ponds, significant groundworks or full joist rebuild 3–5 days. Factors that extend it include bad weather, difficult access, discovering rotten timber or buried services, and waiting for specialist deliveries or electrical sign‑off

Questions to Ask Your Tradie

• have you installed ponds and decking like this before and can you show photos or references

• what guarantees do you provide for liner, pump and timber and how long do they last

• is removal of old decking and disposal included or charged separately

• will you need an electrician for pond equipment and who arranges any third‑party sign‑offs

• how do you protect nearby planting and prevent silt/runoff during works

• what contingency and additional costs should I expect if rotten joists or bad ground are found

How to Avoid Surprises

• confirm clear access and a flat area for materials and skip or van parking

• check and mark underground services before digging and ask for proof of safe digging measures

• arrange or confirm temporary power if needed and discuss whether an electrician will be booked

• move or secure pets and keep children away from work area and open pond during works

• agree where surplus soil, old boards and materials will be stored or removed
