How many hours did it take? We have a guy her in San Diego that can do the same. But it usually take several weeks before we get back the finished product. admin on June 26, 2012 at 7:56 pm Our restorations can take anywhere from about a week to several months. Most of the time, the time frame depends on what parts need to be repaired or replaced and how long it takes to get in those new parts.
