Questions about a loft insulation top-up in Andover
Can you visit Andover outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
How do I pay for work in Andover?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you take on jobs outside Andover?
Yes. We also work in Winchester and Romsey and elsewhere in Hampshire.
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.
