What is raised loft boarding?

Laying boards straight onto the joists compresses the insulation to the joist depth, which can halve its value, and can trap moisture under the boards. We board the area you need, usually around the hatch, and leave the rest of the loft at full depth. More about raised loft boarding.

  • Loft legs fixed to the joists
  • Full-depth insulation under the boarded area
  • Moisture-resistant chipboard or OSB boards

Questions about raised loft boarding in Portsmouth

Can you visit Portsmouth 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.

Do you take on jobs outside Portsmouth?

Yes. We also work in Gosport and Fareham and elsewhere in Hampshire.

Is loft work in Portsmouth 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 board the whole loft?

We can, but we usually advise boarding only what you need. Every boarded area costs more and makes later checks under the floor harder.

How much weight can a boarded loft take?

Ordinary household storage such as boxes and cases is fine on most lofts. Heavy items need the joists assessing. Trussed roofs are lighter than traditional cut roofs.
