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 Cowbridge

Do you take on jobs outside Cowbridge?

Yes. We also work in Llantwit Major and Barry and elsewhere in South Glamorgan.

Will I get a written quote for work in Cowbridge?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Do you charge extra to travel to Cowbridge?

Not normally. Our guide prices include normal travel to Cowbridge. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

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.
