Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.

Questions about loft insulation for a flat in Pwllheli
What do I need to do before you arrive in Pwllheli?
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.
Is loft work in Pwllheli different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Will I get a written quote for work in Pwllheli?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Is there VAT on loft insulation in flats?

Can I insulate the loft above my flat?
Usually yes, with the freeholder's consent. The lease will say who owns and maintains the roof space.
