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.
- Cross layer to a total of 270 to 300 mm
- Gaps in the existing layer filled
- Tank jacket and pipe lagging in the loft
Why book with us in Croydon
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
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.
Clear contact details
Your quote says who to call with questions before, during and after the work.

Questions about a loft insulation top-up in Croydon
How soon can you visit a home in Croydon?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Can a landlord in Croydon 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 take on jobs outside Croydon?
Yes. We also work in Carshalton and Mitcham and elsewhere in Greater London.
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.
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.
