What is a loft insulation top-up?

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.
Photos of the finished loft

Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
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 Larne
Is loft work in Larne 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.
How do I pay for work in Larne?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Will I get a written quote for work in Larne?
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.
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.
