James Hardie Building Products recently launched an iOS compatible 3D application that helps siding contractors obtain complete and accurate measurements of siding, trim, soffit and windows from smartphone photos. The app is free on iTunes, and an Android version is currently in development.

With the snap of a few photos, contractors can easily obtain exterior measurements and a 3D rendering of a home, which greatly reduces the guesswork of job estimates. And with 95 percent accuracy, it eliminates the need for manually re-measuring, saving replacement contractors time and money.

“We love the app. I was skeptical of how useful and accurate this program would be, but have found it remarkably accurate,” says Paul Trautmann, owner of Timberland Exteriors in Stillwater, Minn.

The app allows users to interchange exterior design elements like windows and colors, so replacement contractors can give clients an instant visual of their home. With a 360-degree view, users can inspect every element of a home for a preview of the final product.
