The coldest room in this 1880's built home had sloping floors. By insulating the walls and encapsulating the crawlspace, the outside air is now blocked from coming in. Using our SmartJack system we stabilized the floors. The SmartJack system is made up of glavanized steel beams and jacks. The jacks are capable of supporting up to 50,000 pounds each and are strong enough to be used to adjust and lift the floors back up.
