I anticipated better results on my driveway after speaking with Alan. I had my driveway and patio power washed after explaining that tenants stained both areas. It appears that the driveway would benefit from a second treatment or a more aggressive treatment. I am awaiting a response from Alan. I am antoished that Alan choose a verbal insult in lieu of a second attempt at treating my driveway. Best of luck with the business. The photos are after shots. The before shots are the same.
