Building a room on decking and preventing rain damage Drainage pipes, concrete, footings and foundations. Post your questions and find answers here

I had a builder build a sun room on my decking but I have tried without success to stop the rain coming through the decking grooves on the inside. I am concerned about rotting decking over time and the sun room collapsing. Is there anyway I can support the wooden but heavy wall that has the French doors, under the decking in case of rot?? Like bearers??

Many thanks

Hi margaret 86
If you can get underneath the decking, depending which way the boards are run you could add noggins or an additional joist.

Thank you. Going to be difficult but guessed this would be the way to go. I really appreciate your reply. Margaret
