Building a Home-How To Mold-Proof It

When building a home, it is very important to be diligent and observant during the construction process. Many times, homes will be saturated with rain before the roof is put on. This potentially can lead to mold growth on all plywood and supports. If you suspect that you have mold during the construction process, you should contact your builder to have it inspected by a certified mold professional.
How Can I Prevent Mold In My New Home?

·         Installation of a proper dehumidifier for the size of the house to control the moisture levels
·         Proper drainage systems on the inside and outside of the home. We highly recommend the installation of “dimple board” to the outside foundation walls prior to back-filling of the foundation. This provides a water-proof barrier of those outer walls. A French drain system on the inside and outside around the foundation’s perimeter is also very important.
·         Proper grading with a positive pitch away from the foundation.
·         Application of mold-proof coatings on potential surfaces for mold growth (i.e.: plywood and supports, framing, basement block walls).
·         Calculating the amount of roof square footage you have to determine the correct size gutter and down spouts for your house. Don’t rely on the builder for this. Have a professional gutter company review the plans of the home to determine the correct sizes you need. A minimum of six foot extensions for your down spouts is recommended.
·         Ensure your builder or contractor is following all insulation and ventilation codes for your area. Call your local town code enforcement office for this information.
·         Hire an independent inspector for each phase of work throughout the building process. Our company had a six year old home that was infested with mold due to the lack of knowledgeable contractors.  The picture shown here is of the same 6 year old house with mold growth on the plywood roof decking.  This was due to the insulation contractor not insulating the roof area correctly. There were no baffles installed for the proper air flow to the ridge vent.    

Doing these preventive measures can save you a lot of money and potential health issues, not to mention headaches in resolving unnecessary problems with your brand new home. Your best interests for you and your family should always be the top priority.
