When they rust through or crack, the floor loses its support and you end up with soft spots, sagging boards, and eventually a floor that cannot hold a load safely. Keep Them Rolling Trailer Repair provides mobile crossmember repair and replacement across Morris County NJ. We get under your trailer, cut out the bad crossmembers, and weld in new ones that are ready for heavy use. ## When You Need Crossmember Repair Soft spots in your trailer floor are the most obvious sign of crossmember failure. If the floor flexes or gives when you walk on it, the crossmembers underneath are no longer providing support. Look underneath your trailer for visible rust on the crossmembers. Surface rust is one thing, but when the rust has eaten through the steel, the crossmember has lost its strength. Floor boards that sag between support points tell you the crossmembers have failed in that area. Cracked or completely broken crossmembers need replacement before you load that trailer again. If rust has spread beyond the crossmembers into the frame rails, you may need [full frame welding and structural repair](/frame-repair). ## Our Crossmember Repair Process We inspect every crossmember from underneath the trailer, checking for rust, cracks, and structural failure. We document which crossmembers need replacement and which ones are still solid. We cut out the damaged crossmembers, clean the frame rails where they attach, and weld new steel crossmembers into position. The new crossmembers are matched to the original size and spacing to properly support the floor. If the floor boards above the damaged crossmembers have also failed, we can replace those at the same time. After welding, we apply rust protection coating to the new steel to slow down future corrosion. Bad crossmembers mean a bad floor. We often combine [trailer floor replacement over new crossmembers](/floor-repair-and-replacement) for a complete rebuild. ## Crossmember Repair Cost in Morris County The cost depends on how many crossmembers need replacement. Replacing a few isolated crossmembers is a focused job with a moderate cost. If the rust damage is extensive and most of the crossmembers need replacement, it is a bigger project. Whether the floor also needs replacement above the damaged crossmembers affects the total cost. We always inspect first and give you a clear, honest price before we begin. No surprises. Fleet customers with 3 or more trailers receive a 10% discount on every service call. ## Why Choose Keep Them Rolling We have over 30 years of experience working underneath trailers.
