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.

Questions about a loft insulation top-up in Somerset
Are your prices the same across Somerset?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.
Which council covers my address in Somerset?
Councils in Somerset include Somerset, Bath and North East Somerset and North Somerset. Your council matters for building control questions and some funding schemes.
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.
