House wrap seams and capillary action
Good Afternoon all,
First we would like to thank all the contributors here who have provided us with a wealth of information as we build our home. The house is located in what we’re guessing is 6A (Southern Ontario in Canada). We have a question RE housewrap (typar) installation, specifically the seams. The framing crew wrapped each wall prior to raising them without any overlap between seams. Our concerns is that this will encourage water intrusion via capillary action. We have attached a couple of pictures to illustrate. Any advice on how to best deal with it?
We’re appreciative of any input the experts here can give us!
Thanks!

You are correct to be concerned. Those seams should be carefully taped with a high-quality tape.
Haz,
Overlapping at seams is required by the Ontario Building Code.

Thank you so much, Michael and Malcolm! It's nice to know we're not crazy and that our concerns about water intrusion are valid. We have taped them with blue tuck tape and where possible covered the seams with additional typar sheets that span the seams (shingled from bottom and taped at all margins), as well as taped the many cuts and abrasions.
Thank you again!! :)
