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
- Eaves ventilation kept clear
- Depth check and photos before and after
Why book with us in Keynsham
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.

Questions about a loft insulation top-up in Keynsham
How soon can you visit a home in Keynsham?
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.
Is loft work in Keynsham different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Will I get a written quote for work in Keynsham?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
