What is a loft insulation top-up?

Why book with us in Carmarthen
Honest about grants
If you might qualify for funding, we tell you before we quote.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
How much does a loft insulation top-up cost in Carmarthen?

Building regulations in Wales

Questions about a loft insulation top-up in Carmarthen
Do you take on jobs outside Carmarthen?
Yes. We also work in Llanelli and Ammanford and elsewhere in Dyfed.
How soon can you visit a home in Carmarthen?
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.
Can you visit Carmarthen 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.
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.
