- Cost - Almost every home built today uses mass-produced factory built components such as floor joists, roof trusses,
wallboard, kitchen & bath cabinets and pre-hung windows and doors. As the home building process has evolved, an ever increasing
amount of the construction is being completed in the factory. Building components in a factory reduces the cost of expensive
on-site labor and provides for more efficient use of materials.
Several years ago the National Association of Home
Builders sponsored a wood framing competition. It took 148 man hours to assemble a components framed structure, compared with
401 man hours to frame the same house using conventional methods. The modular home generated 13 yards of less scrap while
needing 5300 fewer feet of board lumber. The cost savings was approximately 15%.
- State of the art technology
- More sophisticated and powerful equipment means every home is built with square corners and plumb walls. Site builders will
often find creative ways to square up corners and walls during framing.
- Climate Control - Black mold is a
common problem in many houses these days. Most site built homes will be rained on numerous times before the roof goes on.
The lumber gets saturated leading to mold and warping problems. Factory built homes do not encounter these issues, nor do
they experience construction slowdowns due to weather related problems.
- Quality Control - Modular homes are
subject to far more inspections than site built homes. At each stage of production, from framing to finish work, there are
quality control experts with check lists to ensure the workmanship quality of the new home.
