What is an insulated loft hatch?

We fit a new insulated hatch into the existing opening, or enlarge the opening if it is too small to get through safely or to fit a ladder. The frame is sealed to the ceiling and the trims are finished ready for painting. More about an insulated loft hatch.

Questions about an insulated loft hatch in Porthmadog

Do you take on jobs outside Porthmadog?

Yes. We also work in Pwllheli and Caernarfon and elsewhere in Gwynedd.

Can you visit Porthmadog 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.

Is loft work in Porthmadog 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.

Can you make my loft hatch bigger?

Yes. We trim the joists, support them and fit a new insulated hatch. It is often done with a loft ladder.

Do I need a fire-rated hatch?

In most houses, no. In some flats, three-storey houses and loft conversions the ceiling is part of the fire protection and a fire-rated hatch is needed. We check.
