Hi all, I'd be v grateful for views / advice, please, re my 'solution' & whether I should get a professional in?! A couple of years ago we had this problem, and called in a builder, who provided and 'installed' the replacement doorstep (rear door). A year or so later, it started to get a bit wobbly, and this worsened - see photo. Last month I bit the bullet and pulled it out; I found what appeared to be broken / crumbled mortar and brick (and some 'spacers') underneath. To try to assess the situation & maybe do a temporary fix 'while we try to get a builder'; I pulled / swept away what had broken / crumbled, and found sound brickwork, about 45mm below the level of where the bottom of the step should be. Fortunately, I had some narrow timber pieces of about the right cross section (as a 'stack' of 2), each c. 20mm x 40mm, to lay along the length of this brickwork, close in to where the 'inner edge' of doorstep needs to be. This gave a nice tight gap - between these new 'supporting' timbers and the bottom ends of the doorframe sides - to force the step back into (I had to chamfer the 'outer edge' of the top supporting timber so that the step would ride onto it). Then, as the resulting gap below the outer edge of the doorstep was only 8mm, I plugged that with timber strip and spacers. 'Exam question' is: Would a builder do a better job, i.e. longer lasting, & if so, (a) how would he / she do this and (b) how / why would it be better? Or, would what I have described - plus painting the step and putting a little sealant round wherever it meets other bits of structure (doorframe, door aperture, ground) - mean 'Job's a good-'un' '? Thanks v much.
