What is a loft insulation top-up?
Before we quote we measure the existing layer in several places and check its condition. If it is wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.

Questions about a loft insulation top-up in Whitstable
Do you cover all of CT5?
Yes, we cover the CT5 postcode district and the districts around Whitstable.
Do you take on jobs outside Whitstable?
Yes. We also work in Herne Bay and Canterbury and elsewhere in Kent.
Do you charge extra to travel to Whitstable?
Not normally. Our guide prices include normal travel to Whitstable. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
