Mold Prevention during the Design
& Construction of a New Home

All wood, plywood, chipboard, drywall, and other cellulose-based construction materials must never be stored on the ground during construction, or be left uncovered outdoors [to keep the materials dry if it rains].
Until the house is completely shingled and sided and windows and doors installed, the house-under-construction should be covered completely at the end of every work day to keep the home from being rained on.
Beneath your roof shingles should be a high-quality roofing membrane to waterproof your roof.
Covering every night is time-consuming, but it is far better than owning a mold-infested home which will harm both your health and your finances.
Inspect all timbers and building materials for visual evidence of mold growth [e.g., black or dark blue or green stains on timbers]. Spray all timbers, plywood, chipboard, drywall, etc. on all surfaces with at least two set sprayings of wood protectant, with drying in between the sprayings.
Make sure your plumbing water supply, drain, and sewer pipes and plumbing fixtures are of the highest quality and installed by a master plumber, and not by some untrained illegal immigrants [a huge quality control problem in the home building industry].
Be sure your concrete floor slab, garage concrete floor, and basement floors and walls are built with sufficient amounts of waterproofing compound mixed into the concrete to make the concrete absolutely impervious to water penetration.
Install a high quality water proof barrier [not just plastic sheeting] beneath concrete floors as an additional water barrier to keep water from rising out of the ground to wet the concrete and therefore the wood walls resting on the concrete floors.
When you first have water running in your plumbing system, use a hidden moisture meter to scan all floors, walls, and ceilins for hidden water leaks.
Make sure your heating/cooling ducts are made of sheet metal with any insulation being on the outside of the ducts, not inside the ducts. Sheet metal ducts without insulation inside can be cleaned of mold contamination if ever necessary in the future.
Make sure all dryer, kitchen, and bathroom vents go by well-connected pipe directly outdoors and not in the attic, crawl space, or walls or ceiling. Put an under-the-dishwasher protective plastic mat to protect the floor against dishwasher leaks and overflows and to alert you of a water problem [Mold Mart].
Install high-capacity ultraviolet lights [388,000 µwats per second of exposure to air movement] in the return air ducts of your heating/cooling system to kill all airborne mold spores and other biological airborne threats..
Install a "mass media", very thick hepa filter in the return air duct to filter out airborne mold spores and other pollutants.
