Questions about a loft insulation top-up in Corby
How do I pay for work in Corby?
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 Corby?
Yes. We also work in Kettering and Market Harborough and elsewhere in Northamptonshire.
Can a landlord in Corby book work for a tenanted house?
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.
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.
