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.

Why book with us in Aberdare
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Honest about grants
If you might qualify for funding, we tell you before we quote.
Photos of the finished loft
You see the work done without climbing the ladder.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.

Questions about a loft insulation top-up in Aberdare
How do I pay for work in Aberdare?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
What do I need to do before you arrive in Aberdare?
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.
Do you take on jobs outside Aberdare?
Yes. We also work in Rhondda and Merthyr Tydfil and elsewhere in Mid Glamorgan.
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.
