    Let's talk vertical foundation cracks.

    What would be common causes of a 1/4 inch crack in a 60 yr old house, ( there is a large tree about 15 feet away)? Crack has been filled with a polyurethane compound with a lifetime warranty.

    how long has the crack been there? how deep is the crack? are there others? and what is the tree outside?

    a 1/4inch crack seems downright odd especially if it was caused by a tree but has happened when a large older tree attempts to go up, but 1/4inch is tiny.

    Settling is a common cause.
    Void developing under the slab is a little more of a concern unless it's been there for a while (most common cause is water moving the foundations.
    Drying soil under the house caused from really low rain fall can cause cracks.

    when you say 1/4inch crack, do you mean a 1/4inch wide crack?
