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 Cardiff
Can you visit Cardiff outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
What do I need to do before you arrive in Cardiff?
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 Cardiff?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
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.
