Exactly what happens if I have a problem with the sash window installer?

A: Firstly, we expect the installer to deal with the situation, quickly and without making a fuss. If the installer fails to take the appropriate action, we will appoint another Bygone authorised installer to complete the work, to your satisfaction.

Obviously, to offer this reassurance, we must know who the installing company is, that way we safeguard our interest… and you get a double guarantee at no extra cost.
