Guides

Plain answers to the questions people ask before they ask for a price.

What it costs per square metre, when spray foam is the right call and when it is not, and what we can tell from photographs before anyone climbs a ladder. Written by the people who do the work.

  • Every guide opens with the short answer
  • The published rates, not a rate card
  • Where a guide cannot answer for your roof, it says what can

The rates are published and they are from rates: the figure falls as the area rises, and the objective sets the depth. A firm price needs the building.

If you are starting cold

Read them in this order and you arrive with the right question.

Half an hour, end to end. Each guide ends where the next begins, and every one of them works without giving us anything.

01What it costs

The published rates, what moves them, and a rough budget for your roof area.

Cost guide 02Whether it is the right call

Spray foam from beneath or a new skin on top: which your roof is asking for.

The comparison 03What to send

Five photographs from the floor, or a survey. The guide tells you which.

Your brief.
A specialist.

If you already know the thickness or U-value you need, we price to it and confirm it is right; if not, we work it out with you. Tell us what you know about the building and the problem; if something is uncertain, say so. Someone who does this every day reads it and comes back to you.

Start a project brief About five minutes. Photographs help; nothing else is needed.
