Michelle, I apologize that you were not satisfied. Our electronic phone records indicate that we tried to contact you twice after your cleaning with no response. If you were not pleased with your results at the time we wish you would have contacted us instead of 6 months later, so we could have addressed any issues or concerns. For the integrity of our company and value of our service, our number one priority is to leave customers satisfied. Our experts highly recommend routine house washes and driveway cleanings as part of regular maintenance for homeowners; this usually prevents buildup and decay overtime.
