    on the mortar that joins the back of the house on to were our conservatory starts, i dont know how good the footing are, but it cracks on the inside and the outside i keep filling the inside (once a year) and a bit more often on the outside just looks unsightly i just put in a bit of sand and cement but it doesnt last long (the line of brick work is just butted up to the back of the house)

    is there any silicon you could put in to it or would that look awful say brown?)

    conservatory about 12 yrs old

    is this normal??
    thanks

    ive seen large side of our building done at work in grey.

    is it a idea to rake out the old mortar or just go over the top of it ??

    thanks in advance
