In building, remodeling and football, the old adage rings true – the best defence is a good offence.

Pressure treated lumber is often used in building sills for wet areas like kitchens and bathrooms. It’s also often used in fixing (sistering) rotted floor joists in old buildings.

Keep in mind that most pressure treated lumber is often wet and mold contaminated (usually with Penicillium sp. and Aspergillus sp.). If you plan to use it inside (particularly as floor joists,  it’s best to power wash the lumber first.

There is no need to power wash if you plan to use it for exterior decking or exterior stairs, etc.

Here are a few quick tips when renovating:

1. When drywalling, keep drywall at least half inch off the floor.   This will prevent moisture transfer in case of spills.  The baseboard or trim will cover the gap.
2. Paint primer/sealer on back and ends of trim or baseboard.
3. Put a bead of silicone caulking along the bottom and back of baseboard or trim.  This way moisture from floor will not transfer to wall board or “sheet rock”.
4. Spray lacquer on the backs of cabinets before adhering them to the wall.  It dries quickly and forms a moisture seal.
5. Avoid fiberglass floor insulation above damp crawl spaces.   It provides the perfect breeding ground for mold.  Instead, use solid board insulating foam which holds less moisture.

These simple steps will help maintain a healthy home.
