Specification and comparisons

Turning 'prepare as necessary' into something you can check

The phrase 'prepare as necessary' appears on more decorating quotes than any other, and it means almost nothing on its own. It commits a contractor to doing some preparation, but not to any particular standard, extent or method — which means two contractors offering identical wording can deliver very different results for the same price.

Questions we are asked about this

Can I insist a contractor removes this phrase entirely?

You can ask for it to be replaced with specifics, and a contractor confident in their scope should be able to do this without difficulty.

What if the real extent of preparation only shows up once work starts?

This is normal on older buildings — the fix is not avoiding the phrase altogether but agreeing a simple process for pricing and approving extra work as it is found.

Does defining preparation in detail make a quote longer?

Slightly, but a few extra lines describing filler standards and coating treatment are far cheaper than a dispute over finish quality later.

Why the phrase persists

It survives because genuine preparation needs do vary by surface and cannot always be fully known until decorators are on site scraping and sanding. Used honestly, it acknowledges that some judgement will be needed on the day. Used carelessly, it becomes a way to avoid committing to anything measurable.

What a defined version should state instead

A workable version names the expected actions for the condition observed at survey — for example, filling cracks up to a stated width, sanding existing gloss to a stated key, or stripping wallpaper rather than painting over it — with an agreed process for anything found beyond that scope once work starts.

  • The filler standard expected for cracks and holes of typical sizes
  • Whether existing coatings are sanded, washed down or fully stripped
  • How unexpected damage, once uncovered, will be priced and agreed

Building in a fair mechanism for the unknown

Rather than trying to predict every possible condition in advance, a good specification pairs a defined baseline standard with a simple process for additional work: a photograph, a description of the extra scope and a price, agreed before it proceeds. This protects both sides without pretending certainty that does not exist.

What this looks like at snagging stage

If preparation was defined clearly at the outset, snagging becomes a straightforward comparison against that standard. If it was left as 'prepare as necessary', snagging disputes tend to circle back to differing expectations that were never actually agreed in the first place.

How we work on this

  • We describe preparation standards for the actual condition surveyed, not a generic phrase
  • We agree a clear process for pricing anything found once work is underway
  • We record preparation carried out per room so it can be checked at handover

Ask us to convert any vague preparation line on your existing quote into a defined, checkable standard.

A vague preparation phrase only becomes useful once it is turned into something you can actually inspect against.
