We will always provide you with a complete written estimate that fully explains the scope of the work to be performed. We have developed a system to price each job by a bid as opposed to parts and labor. The only things that change from our estimates are unforeseen or extenuating circumstances which we will call you about to keep you informed throughout the process.


We will always provide you with an estimated time to completion. We will work diligently to adhere to that time schedule, but please remember this is an estimate, and this is auto repair, not everything can be planned for. That being said, there are times when things happen that are out of our control, fortunately for you, the hours don’t climb on your bill if this happens. If something unforeseen happens and we can not finish your repair on time, we will call you as soon as we are aware of any issues and let you know what happened, why, and provide an updated estimate for time to completion.

When this happens, bring your vehicle to Brotherhood Garage, and our team of experts will determine the root cause of the sound or light.
