Corrections, disagreements and suggestions for subjects worth covering are all welcome.

What we can help with

Putting right something we have got wrong, or covering a subject that keeps coming up. We cannot advise on a specific installation, sign anything off, or settle a dispute with a contractor - none of that can be done responsibly by anyone who has not seen the job.

For anything with a safety question attached, the authority having jurisdiction where you are working is the right call, and it is a free one.
