We have log house built in 1999, crew that put up the shell missed butyl sealant between a few of the logs (tongue and groove D-style, Kuhns Bros). When a driving rain (winds over 20 mph) from the east hits that side of the house, some water comes through. Outside has been chalked by a professional, but we still (maybe twice a year) get water through these seams. How should I repair this leak?
Leaks are one of the most difficult things to fix on a log home. It could be coming in on the far end of the house and running down the channel of the logs till it finds a way in on the opposite end of the house. Make sure that all the windows and doors are caulked, the butt joints (where 2 log ends meet in a wall), and all chink lines. Corners are especially susceptible to catching water and channeling it in.
