Questions about a loft insulation top-up in Melksham

How do I pay for work in Melksham?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Do you cover all of SN12?

Yes, we cover the SN12 postcode district and the districts around Melksham.

What do I need to do before you arrive in Melksham?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

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 new insulation go on top of old insulation?

Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
