    If you haven't checked your home has weak mortar, you should do so today.
    Drag a screwdriver over a joint, if it powders and falls out you too have a weak mortar time-bomb!

    This is the story of just one site A Taylor Wimpey Development in Peebles Scotland.
    There are many others up and down the country with most plc house builders.

    It is their reaction and that of the NHBC which should cause for most concern.

    hi. I had issues with my the mortar in my new build estate that seems similar to the homes in Peebles. The house builder have repointed my walls just like they are doing there, the mortar seems solid and is a far better finish. I have one question regarding this. Where my house is located on the NHBC weather exposure map my area is classed severe and it states that the recommended mortar class is an M6. The house builder have used an M4 class of mortar for the original build and repointing. is it just a recommendation that they have to use a certain mix? is it site specific?thanks in advance.
