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.
- Tank jacket and pipe lagging in the loft
- Cross layer to a total of 270 to 300 mm

Questions about a loft insulation top-up in Nailsea
Will I get a written quote for work in Nailsea?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How soon can you visit a home in Nailsea?
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.
Do you take on jobs outside Nailsea?
Yes. We also work in Portishead and Clevedon and elsewhere in Somerset.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
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.
