"My husband and I had spent 13 years remodeling our 1873 house by ourselves. When it came time to do our dream project of adding a sunroom, finding a contractor to do the work instead of doing it ourselves was a very important decision to us. We met with several contractors and knew instantly that John and his son Nate at Addition Doctors were the people we wanted taking on this project. John and Nate were so great to work with. They were the only company we met with who gave us a computer generated model of what the project would look like so we had a very clear vision of the end product. They were the only company to quote us the project under the budget we told them we had to work with. They kept us up to date at every step of the project and there were never any surprises about cost or timing. They had great ideas for the project when we weren't exactly sure what should or could be done. We love our finished sunroom. The quality of work and service they gave was excellent. We would highly recommend Addition Doctors for anyone who is looking to have quality work done to their home."

"Des Moines Area Roofing was professional, trustworthy, and demonstrated excellent attention to detail from initial contact to job completion. Cleanup was so thorough that the next day you wouldn't even know that such a major project had taken place. It has been 2 weeks since the new roofs and we haven't seen even one stray nail left behind (and they did a complete tear down to both buildings, right down to the wood). An excellent company with which to do business. I offer my highest possible recommendation."

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Whether a prefab home is worth it or not will depend on your personal needs and preferences.
