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 Haverfordwest
What do I need to do before you arrive in Haverfordwest?
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.
Will I get a written quote for work in Haverfordwest?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you take on jobs outside Haverfordwest?
Yes. We also work in Milford Haven and Pembroke Dock and elsewhere in Dyfed.
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.
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.
