Why Do I Have Over Spanned Floor Joists?

The support beams and floor joists in your crawl space are designed to support the weight of your home. The floor joists have to be precisely spaced otherwise you’ll have a sagging floor or uneven floors. And if the floor joists aren’t supported properly then your floor will eventually cave in, creating even bigger problems – which can stem from:E


Is your crawl space sealed or do you have open vents? An unsealed crawl space allows moisture – which produces mold. Mold thrives on organic (any living material – like trees – or wood) material, which causes wood rot, decay, and structural damage.E
