What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

  • Cables lifted clear of the insulation where possible
  • Tank jacket and pipe lagging in the loft

Why book with us in Weymouth

We measure before we quote

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Fixed written price

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

Boarding done properly

Storage boards go on loft legs, never straight onto the insulation.

No pressure selling

You get everything in writing and decide in your own time.

Questions about loft insulation in Weymouth

Will I get a written quote for work in Weymouth?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

What do I need to do before you arrive in Weymouth?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Do you charge extra to travel to Weymouth?

Not normally. Our guide prices include normal travel to Weymouth. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Can you insulate around downlights?

Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.

Do I need to empty my loft first?

The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
