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 Rhondda
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.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Questions about a loft insulation top-up in Rhondda
How soon can you visit a home in Rhondda?
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 Rhondda 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.
Do you take on jobs outside Rhondda?
Yes. We also work in Tonypandy and Aberdare and elsewhere in Mid Glamorgan.
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.
