Before we quote we measure the existing layer in several places and check its condition. If it is dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Questions about a loft insulation top-up in Dunstable
Do you cover all of LU6?
Yes, we cover the LU6 postcode district and the districts around Dunstable.
How do I pay for work in Dunstable?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Will I get a written quote for work in Dunstable?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
