Questions about a loft insulation top-up in Sleaford

Do you charge extra to travel to Sleaford?

Not normally. Our guide prices include normal travel to Sleaford. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

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

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.

How do I pay for work in Sleaford?

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

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.

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.
