Questions about a loft insulation top-up in Eastleigh

Do you charge extra to travel to Eastleigh?

Not normally. Our guide prices include normal travel to Eastleigh. 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 Eastleigh?

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 Eastleigh?

Yes. We also work in Hedge End and Southampton and elsewhere in Hampshire.

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 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.
