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 Welwyn Garden City
Do you take on jobs outside Welwyn Garden City?
Yes. We also work in Hatfield and Hertford and elsewhere in Hertfordshire.
Is loft work in Welwyn Garden City 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 cover all of AL8?
Yes, we cover the AL8 postcode district and the districts around Welwyn Garden City.
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.
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.
