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 Chelsea
Can a landlord in Chelsea book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you cover all of SW3?
Yes, we cover the SW3 postcode district and the districts around Chelsea.
Will I get a written quote for work in Chelsea?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
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.
