SmartJacks could be a fix for sagging or uneven floors above a crawlspace area. During annual maintenance at a home in Manahawkin, NJ, Quality 1st Service Technician Chris checks to ensure that all jacks are in good contact with the beams and the jacks are tightened as necessary to prevent movement. Finally, he ensures that the beams are level. The homeowner is left with level floors above the crawlspace and peace of mind!
