Leaking Interiors from Home Additions
 
We have an 1890's Tidewater farmhouse clad in wood siding. Several years ago we added on in three places around the original house. When we get very hard rains the water passes through the original siding, down the backside of the siding and into the rooms near where the new roofs meet the walls. (seams) I suppose originally that the rain did the same, except it traveled downward to the ground.

We have had carpenters caulk the seams and on the underside of each piece of siding to no avail. My husband thinks we should cover with vinyl, but it seems that there could be another solution. I was thinking that maybe something could be put under the siding in those areas to keep out the leaks.

Anyone???Thank you!!!

Metal flashing should have been used there. Caulking is not a good choice for areas like that. The wood siding can be carefully removed and reinstalled after proper flashing is installed. If you have any pics we could get a better idea of what you have.

When you say Tidewater do you mean as in the Chesapeake Bay?

Any thing would be better than vinyl siding.

Caulk is not meant to be a first line of defense against water intrusion. It was designed to seal small gaps water passes as it is guided down and away by proper flashing so it doesn't get diverted along the way. You could probably empty the caulk aisle at Home Depot and still not fix it. The siding was not installed properly and someone who knows that stuff needs to look at it and tell you what's going on. A siding guy, not a handy man or jack of all trades. And some seams and gaps are not meant to be caulked on siding. They're there to let it breath and naturally drain moisture. When you put sealant in areas where the manufacturer doesn't call for you can make the problem worse by holding moisture inside it and causing more rot.

Frankly,

Leaks are usually exacerbated with the application of sealant to an improperly flashed condition. What kind of wood siding are we talking about? Im not quite understanding the concept of water flowing down the back of your siding. It should be flowing down the face of your siding, and you should have drip caps at openings, and base and counter flashings to redirect water out to the surface of your siding.

sounds like the siding was nailed directly to the studs.. theres no sheathing over the studs or felt paper

In that case I would remove the siding, throw in outlets where you need them and plumbing, Insulate it, sheathe it, black it in and reinstall or replace the siding. Might just as well replace the windows if they suck too.

Big job, but then you would have something.

Be prepared for an expense of some undertaking but as mentioned above, you will need to fix it and fix it right.
