What is a loft insulation top-up?

Before we quote we measure the existing layer in several places and check its condition. If it is wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.

  • Cross layer to a total of 270 to 300 mm

Questions about a loft insulation top-up in Weymouth

How soon can you visit a home in Weymouth?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Can you visit Weymouth outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Do you take on jobs outside Weymouth?

Yes. We also work in Dorchester and Bridport and elsewhere in Dorset.

Can new insulation go on top of old insulation?

Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.

Which way should the top-up layer run?

Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
