Questions about a loft insulation top-up in King's Lynn

How do I pay for work in King's Lynn?

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

Can you visit King's Lynn outside working hours?

Do you take on jobs outside King's Lynn?

Yes. We also work in Swaffham and Dereham and elsewhere in Norfolk.

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.

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.
