Utility trailer repair in Fresno is bench work at Joaquin Ag Repair. The trailer tows in on its own wheels, and the repair is billed at $85 an hour with a one hour minimum and no trip charge.

Axles, hangers, hubs and couplers carry the trailer down the road, so Joaquin looks at those before anyone quotes them. Send a photo first and the answer comes back on the phone.
On the welding rates page, a fender or a ramp hinge on a towed-in trailer is listed at two hours, which comes to $170. Flatbed, gooseneck and dump trailers are covered on the trailer repair shop page, and a trailer that cannot be towed gets a callout instead.
It is $85 an hour at the shop with a one hour minimum and no trip charge. A trailer that cannot be towed gets a callout at $130 an hour with a $450 minimum.
If the damage is on the trailer itself, tow the whole trailer in. A ramp or a gate that unbolts can come in on its own.
Axles, hangers and hubs get looked at before a quote, so send a photo and Joaquin will say whether it is a shop job.
