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 dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.
- Cross layer to a total of 270 to 300 mm

Why book with us in Spennymoor
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.

Questions about a loft insulation top-up in Spennymoor
Do you take on jobs outside Spennymoor?
Yes. We also work in Bishop Auckland and Durham and elsewhere in County Durham.
How soon can you visit a home in Spennymoor?
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.
Do you charge extra to travel to Spennymoor?
Not normally. Our guide prices include normal travel to Spennymoor. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
