Will I get a written quote for work in Holyhead?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

It depends on the product's thermal conductivity. Some need slightly more depth than mineral wool to reach the same U-value, which we allow for on the quote.
