Hi, I have a bowed wooden lintel over what was once a wooden-framed window but has been open into to an extansion for over 20 years. the lintel is significantly bowed and I am concerned about its weight bearing capabilities over the next years (with added furniture upstairs etc). - the span between brick support is 6ft. The lintel supports the inner wall of the upstars outside cavity walls which includes a window so its not all brickwork on top but a fair amount is. I see that I have 4 choices 1 leave it, hope for the best and tell folk not put anything too heavy in the room above (I wont sleep well!) 2 Get a builder in which I really cant afford in money, time and having to move stuff out from the area.during the work. 3.put a wooden ot metal supprt in the middle of beem - this cuts the opening in half wich I dont really want to do. 4. Buy an rsj. support it at either end with acrows and box it in. I recckon £250 would see the whole job done. - this is my prefered solution and easily within my capabilities (which are modest as far as diy is concerned). I just want to check that option 4 is a reasonable solution and also not breaking any regulations or anything. I doubt it would because it would be safer than just leaving it like it has been over the last 20-30 years. It would be very helpful to ready your comments please. thanks Beany

Creating a corner mounting system with 2x6s and 2x4s there will essentially be 2x6 rails that my frame will sit on and get fastened to. This is due to odd stud placement in my office and the mount spacing required for my corner desk. I don't want to damage the paint, 1x primer, 2x Valspar Signature paint. Any suggestions on a barrier to put in between the wood and wall to keep the paint from adhering to the wood? This is just in case I want to take it down after some time. Thanks!
