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.

  • Cross layer to a total of 270 to 300 mm
  • Tank jacket and pipe lagging in the loft
  • Depth check and photos before and after

We measure before we quote

Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Fixed written price

The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.

Questions about a loft insulation top-up in Durham

Do you charge extra to travel to Durham?

Not normally. Our guide prices include normal travel to Durham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Can a landlord in Durham book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Will I get a written quote for work in Durham?

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.

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.
