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.

  • Gaps in the existing layer filled
  • Depth check and photos before and after
  • Tank jacket and pipe lagging in the loft

Why book with us in Blackburn

No pressure selling

You get everything in writing and decide in your own time.

Boarding done properly

Storage boards go on loft legs, never straight onto the insulation.

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

Tank and pipes protected

Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Questions about a loft insulation top-up in Blackburn

Is loft work in Blackburn 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.

Will I get a written quote for work in Blackburn?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Do you take on jobs outside Blackburn?

Yes. We also work in Darwen and Accrington and elsewhere in Lancashire.

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.
