    Solid wall lintel type

    Hi all, I'm currently removing some patio doors to shorten the opening height to allow for double doors and a wall plate for a flat roof which will run across the sagging soldiers.

    Soldiers dropping above window. No lintels??

    I'm looking at buying a 1940's 3 bed semi solid brick. The soldiers above the window are dropping and need sorting out. The plasterboard to the soffit of the reveal inside is sagging and feels moist. I imagine weather is seeping through here causing that. What kind of lintels would you use for...
