- Running the hardwood boards perpendicular to floor joists will prevents sagging.
- Leave a 3/8-inch gap between the walls and the flooring to allow the wood to expand and contract. You'll cover this gap later with baseboard and shoe molding.
- Leave the hardwood flooring material in your house for 10 to 14 days to acclimate to your room’s environment. This will limit the amount of natural expanding and contracting your flooring will undergo in its lifetime.
- If you suspect your old flooring may contain asbestos, don’t remove or disturb the flooring until it is tested. Consider installing your new floors on top of the old flooring.
