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 Sunderland
How do I pay for work in Sunderland?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you charge extra to travel to Sunderland?
Not normally. Our guide prices include normal travel to Sunderland. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will I get a written quote for work in Sunderland?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
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.
