Heavy tools are where DIY gets serious, and where money tends to vanish fastest. Pick the wrong pressure washer and you can etch tramlines straight into your render. Go too light on a wacker plate and the sub-base never properly compacts, so the patio you laid so carefully starts to sink come spring. The good part is that choosing well takes about five minutes to learn, and once it clicks you stop overpaying for the wrong kit. Buy, hire or borrow, this is how to choose.

Pressure washers. Ignore the headline bar rating; it only tells you half the story. What actually shifts grime is pressure and water flow working together, so look at the litres per minute as well. For patios and driveways, a mid-range machine with a rotary surface cleaner lifts moss in a fraction of the time a bare lance manages. On softer surfaces such as render, timber decking or painted brick, wind the pressure right down or you will take off more than the dirt. One rule rarely lets you down: match the machine to the dirtiest job on your list, not the average one.

Plate compactors, or wacker plates. These are chosen on plate weight and compaction force. A lighter plate is ideal for bedding block paving and small patios. Sub-bases, driveways and bigger areas want a heavier plate, which is also a brute to heave in and out of a car boot, so work out how you will move it before you commit. It is the textbook borrow tool: two days of hard graft, then years of gathering dust.

Garden shredders. Two quite different machines share one name. Impact, or blade, shredders are cheaper and tear through dry, woody prunings quickly. Quiet, or roller, shredders crush the green, sappy growth that would jam a blade within seconds. Choose by what is actually growing in your garden rather than by the lowest price.
Cutting tools. A tile cutter, a mitre saw and a circular saw are all saws, and none of them will stand in for another. Borrowing means you bring the right blade to each job instead of bullying one tool through three jobs it was never meant for, and ruining your material in the process.

One word on safety. Heavy tools earn their respect. Eye and ear protection, the right outdoor-rated power supply, and a quick test run before you start are not optional extras. Two minutes checking the cable, the bit and the guard can save your afternoon, or a good deal more.

For a single weekend, the right heavy tool rarely justifies the price tag, the storage or the upkeep that comes after. Borrowing the correct machine from a neighbour beats owning the wrong one outright. Share more. Own less. Build together.
