Every email you send will be answered as fully as I can and to the best of my knowledge and experience. I usually attach and refer to photos I took on my 100 or so basements I built or help build. I will draw a diagram just for you if it's necessary to explain a point.

I run two businesses. Me, Phil Sacre, and Basement Expert Ltd.
That allows me not to charge VAT on advice but the limited company adds VAT to product sales.
