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.
- Depth check and photos before and after
- Gaps in the existing layer filled

Why book with us in Sidcup
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Photos of the finished loft
You see the work done without climbing the ladder.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.

Questions about a loft insulation top-up in Sidcup
Do you cover all of DA14?
Yes, we cover the DA14 postcode district and the districts around Sidcup.
Do you take on jobs outside Sidcup?
Yes. We also work in Welling and Eltham and elsewhere in Greater London.
Can you visit Sidcup outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
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.
