We have Cedar vertical T&G siding. We are have 3 decks and because when house was built, somehow deck and end of siding were put together so close, some of bottom of sidng where deck meet are rotting.
I went over to home improvmeent store and found something called "End Rot" kit. We are currently working to hire good paint company to paint entire house and not sure if we can ask them to use this on problem areas.
Anyway, any good advise on how to resolve rotting of some of siding on vertical T&G?
This will work if done correctly. ALL of the rotted section needs to be removed. Areas next to the rotted fibers need to be sealed with an epoxy hardener. You will loose the textured surface of your siding. BUT you are still not addressing the root of the problem. The deck needs to be separated from the house. Then repair the siding, install ice and weather shield on the siding behind the ledger plate. Fasten the deck back in place. install flashing under the siding and over the ledger plate to divert water away and not behind the deck.
The should have been a spacer behind the ledger, I use PVC lumber sitting vertical as a spacer.
Never install decking tight to the side of a house.
Always have gutters over any deck to reduce splash back.
