Hey All. Have a little issue we found on a house we are closing on soon, and wanted to get some ideas for repairing it.
The previous owners decided to enclose a porch area and make it into a sunroom. Cool idea, chose great high quality windows etc. This floor is a good 8 inches below the level of the rest of the house floors, and is even with the rest of the concrete pad that was originally just the porch. There is a 8 inch exposed pad border on the outside of the this sunroof.
Because the floor of the sunroom is level with the outside pad, water is coming in under the door and has rotted out the baseboard moulding. THe pad is only .75 inches higher than the driveway as well, so heavy rain simply rolls right towards the house.
My initial thought was I will need to build a subfloor to raise the floor up, then raise the door so its not .25 inches above the pad, but I feel like I am possibly overcomplicating it.
Is there a way to do this differently? The exterior is vinyl siding, interior is tongue and groove knotty pine boards. Floor is ceramic tile. Not opposed to raising the floor if that is the proper repair, just do not want to do more than I need, while still doing it properly.
THanks for any and all help
