    Project Manager Steve C went out to take a look at the concerns the homeowners were having with the sagging floors and cracked floor joist . Steve told the homeowners you can usually remedy sagging problems yourself by “sistering” new joists alongside the existing ones (this also works for stiffening bouncy floors) Steve also recommendation was to add 3 new 4x4 support columns placed on 16x16 solid concrete footers ..First crew Foreman Robert remove electrical cables, pipes and other obstructions. If this is difficult (it often is!), consult your local building inspector ...If a crack or sag is isolated to one area, the sister joist should extend at least 3 ft. on both sides of the problem area. But it’s usually best to run the sister joist over the entire span. When the sagging joists are level, apply a generous bead of construction adhesive to the existing joist. After we was all finish the clients noticed a big difference !
