Why so many lofts need it

A lot of lofts were insulated years ago to the depth that was normal then, often just to the tops of the joists. It has usually settled since. If you can see timber, you’re well short of today’s commonly recommended depth.

How we do it

We roll the new layer across the joists, over what’s there, so the timber is covered and the depth is even. It’s quick and tidy.

When it’s not enough

If the old insulation is damp, dirty or full of droppings, it should come out first. We’ll tell you if that’s the case.

Loft insulation top-up: your questions answered

How do I check my depth?
Push a ruler down through the insulation to the ceiling. If it’s well under 270 mm, or you can see joists, it needs topping up.
Will it make the loft unusable?
Not if you add a raised floor. Otherwise the top layer covers the joists, so you can’t walk on it.
How long does it take?
Usually a few hours to a day.
Is it guaranteed?
Eligible installations come with a guarantee of up to 5 years. Your written quote says whether your job qualifies and what it covers.
