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 Chalfont St Peter

Will I get a written quote for work in Chalfont St Peter?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Do you take on jobs outside Chalfont St Peter?

Yes. We also work in Gerrards Cross and Amersham and elsewhere in Buckinghamshire.

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.
