Building wrap is a very important part of a new home, and it needs to be installed according to the specific instructions from the manufacturer. This can be slower and a bit more tedious than some construction crews prefer, but it is the only way to do it and get excellent results.
The problem is that many crews focus on speed and efficiency. They think about deadlines. They want to get the job done as quickly as possible.
In many cases, experts warn, that means they just put the wrap up in a hurry, without paying careful attention to the instructions. They assume the little details do not matter. They do not worry about using tape properly or double-checking the job. They may not overlap the seams far enough, for instance, or not use tape that is up to code to weather-proof any gaps.
The issue here is that the home then lacks a proper water barrier. It's not as if water is pouring into the house, so the average homeowner will never notice. However, moisture is still getting in under the wrap, which can lead to mildew, mold, rot and drafts. These issues can impact walls, floors and jams.
It's a simple and often hidden mistake, but it can ruin a home and cause long-term damage. This may be very expensive to fix, and it can detract from the home's value. Even a new build may start to show signs of damage very quickly. When this happens, it is important for homeowners to understand all of the legal options they have.
