Building Inspector Job - Kanonkop, MP, 1055

I have noticed some cracking in the corner of my en suite bathroom. The door frame seems to be pulling away from that corner. The outer bedroom wall at the same end of the house may also need attention. It supports the end of the roof. I am concerned about a possible foundation or landslip problem because I need to protect our safety. Also, the corner where the bathroom door closes seems to have lifted a little, resulting in the door sticking upon opening and closing. I need a quotation and also a figure for cost of assessment. I see that landslip is covered in my buildings insurance policy and I need to pre empt and avoid

a disaster before it happens.
