Questions about a loft insulation top-up in Prestatyn
How soon can you visit a home in Prestatyn?
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.

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 Prestatyn?
Yes. We also work in Rhyl and Denbigh and elsewhere in Clwyd.
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.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
