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.
- Gaps in the existing layer filled
- Tank jacket and pipe lagging in the loft

Questions about a loft insulation top-up in Mold
How do I pay for work in Mold?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Can a landlord in Mold book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Can you visit Mold 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.
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.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
