If you are planning an exterior remodeling project that includes new siding you might be wondering if you need house wrap. The first thing to consider is whether your local building codes require house wrap. In many parts of the country it is required. Areas with drier climates are less likely to have house wrap requirements.
The reason that house wrap is a good idea, and is often required, is that it protects your home’s structure from excess moisture. All exterior finishes, such as siding, brick and stone, allow some amount of water to penetrate. House wrap allows this water to sheet off and drain away, protecting your home’s framing elements.
Although house wrap sheds liquid water on the exterior, it does allow water vapor to pass through. This means that humidity from inside the home is allowed to escape reducing the chances for mold and mildew buildup.
So the bottom line is, whether you are considering a DIY project or hiring a contractor, properly installed house-wrap is an important part of the finished job.
A home is among the biggest investments you’ll ever make. So when you choose someone to build, remodel, install or repair the biggest protection of that investment—the exterior—extreme, expert care is advised.
