Chipper is is almost right we owned a shop for 24 years and some are way over 40% and some under. Shops need to make money on parts as well as labor to keep the door open. Many states have laws that you can not go more than 10 % over the estimate without coustomer approval. So if you go to pick up your car and the estimate was $1000.00 and you you get there and they want $1500.00 with out your approval then you would only have to pay $1100.00
It appears, from earlier posts, that J & W Machine has received high marks, for their work.
Geraldo hit the nail on the head.
Potential customers, anywhere, must request an estimate, as complete as possible, with labor time, labor dollar rates and parts pricing policies for all work, current and supplemental.
Regarding the 10% law.
When I lived in Ohio, I worked in a Chevy dealership.
Back then, in the '70's, the 10% law was in effect, for costs OVER and costs UNDER
Using $1,000 as the estimate, we had to be between $900 and $1,100 OR
the customer was responsible for only $25.
It was not enough that a customer could get a financial break, if the repair went under budget.
The State of Ohio found it necessary to give the customer a "bonus", if the estimate went below the 10% guideline.
So, if the estimate, at $1,000, ended up at $850, the customer could LEGALLY
pay $25 bucks, and walk out the door, with an invoice marked "PAID IN FULL".
All it took was one "gotcha" incident, then the dealership/shop began calculating all invoices, like the finest auditor ...... never to fall out of the 10% bounds again.
