Questions about a loft insulation top-up in Bangor, Gwynedd
Do you take on jobs outside Bangor, Gwynedd?
Yes. We also work in Llangefni and Caernarfon and elsewhere in Gwynedd.
How soon can you visit a home in Bangor, Gwynedd?
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.
What do I need to do before you arrive in Bangor, Gwynedd?
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.
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.
