Sick House Syndrome
Ever heard of sick house syndrome? For years unsuspecting occupants of homes and buildings have suffered with illnesses that are now known to stem from places within our homes and places we work. Dark, dirty and damp crawlspaces are a breeding ground for fungi, mold, allergens and dust.
These toxins can live in the crawlspace and become airborne through the heating and air equipment or duct system. Unsealed floors with numerous electrical, mechanical and plumbing penetrations allow a free pathway to enter the home and where contaminants spread.
Sealing ducts, sealing openings and cracks in the floor, and encapsulating the ground with a water proof membrane will create a healthy, energy efficient environment to protect you and your family!
