Questions about a loft insulation top-up in Willesden

How do I pay for work in Willesden?

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

Do you cover all of NW10?

Yes, we cover the NW10 postcode district and the districts around Willesden.

Is loft work in Willesden 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 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.
