Questions about a loft insulation top-up in Denbigh
Is loft work in Denbigh different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
How do I pay for work in Denbigh?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Will I get a written quote for work in Denbigh?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
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.
