    My father in laws living room floor is in a complete state. Majority of the floor joists and wall plates have rotted away and crumbling to the touch. He wants to replace everything.
    The current wall plates are attached to sleeper walls at 3 locations.
    My questions is, when we are putting in new wall plates, do they needed to be put on a mortar bed?should it be mortar bed, dpc then wall plate?
    Then once the wall plates are level is it just a matter of simply nailing the joists to the wall plate or should we be using something like right angle brackets to secure them.
    Any help would be great.

    A wall plate is easier to level and fix the joists down but not essential, if you are going to use them then it's easier to level them with a mortar bed, yes. Thin mortar bed, DPC, thick mortar bed, wallplate. You can just skew nail the joists to the wallplate once the mortar has gone off enough after a day or two, if you can't wait and are pushed for time though just screw a small bracket to the joist and plate as it's less disruptive than a load of hammering.
