Questions about a loft insulation top-up in Kent
How do I book a survey in Kent?
Send the form or call us. We call back to agree a time and confirm it in writing.
Can you quote for several properties in Kent?
Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
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.
