Excel Homes, innovative modular building process

Excel In Process

Excel Modular Homes makes the custom modular process easy. We will work with you from start to finish to make sure your project stays on-time and on-budget. Our 12-step building process* has been developed with more than 20 years of experience to ensure that your home is constructed efficiently and correctly. With this innovative process, you could have your new homeowner in their house in as little as six weeks.

As a builder, this fast, efficient process means you could build more houses in a year – for increased profit – than you would with site-built construction.

This is a typical building process. Actual process may vary.
