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.

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

Questions about a loft insulation top-up in Rhyl
Will I get a written quote for work in Rhyl?
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 Rhyl?
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 cover all of LL18?
Yes, we cover the LL18 postcode district and the districts around Rhyl.
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 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.
