This company has extremely unclear communication ability when it comes to their work and pricing. When work is not done as per customer specification, they refuse to come back to fix the job. In addition, the pricing is at the top end which does not result in the quality of the work performed. I would be looking at a different company for your plumbing needs.

This is a recording of a phone call to OA Plumbing regarding a bathtub leaking after they installed it.
Ondre is the owner loves to get his customers money, but when there is a problem it's a "couple of weeks" to have a look.
