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.

Questions about a loft insulation top-up in Tredegar
Do you cover all of NP22?
Yes, we cover the NP22 postcode district and the districts around Tredegar.
Do you take on jobs outside Tredegar?
Yes. We also work in Ebbw Vale and Blackwood and elsewhere in Gwent.
Can a landlord in Tredegar book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
