What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

Questions about loft insulation in Northampton

Will I get a written quote for work in Northampton?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Is loft work in Northampton 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 visit Northampton 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 I need to empty my loft first?

The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.

Does loft insulation need building control approval?

On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
