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 dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Why book with us in Mitcham
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
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.

Questions about a loft insulation top-up in Mitcham
What do I need to do before you arrive in Mitcham?
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.
Can a landlord in Mitcham book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you cover all of CR4?
Yes, we cover the CR4 postcode district and the districts around Mitcham.
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.
