What is a loft insulation top-up?

Questions about a loft insulation top-up in Sunbury-on-Thames

Will I get a written quote for work in Sunbury-on-Thames?

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

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

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.

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.
