Questions about a loft insulation top-up in Wellingborough
Do you cover all of NN8?
Yes, we cover the NN8 postcode district and the districts around Wellingborough.

Can a landlord in Wellingborough book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
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.
