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 Mangotsfield
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
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.

Questions about a loft insulation top-up in Mangotsfield
Is loft work in Mangotsfield 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 Mangotsfield?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
How soon can you visit a home in Mangotsfield?
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 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.
