I have never been in a position to write such a review, until I unfortunately dealt with Chris Williams, owner of Lawn Doctor in Spokane, WA. As a customer of 3 years, they have provided satisfactory service; until they damaged my property and then they suddenly can't be reached. I was just days away from having a new, walkway project completed when Lawn Doctor came by to do a fertilizer application with both spray and granules. The new steps on this expensive project were made of an extremely porous concrete mixture. The next morning after the application, my beautiful steps had unsightly black stains. I immediately called Lawn Doctor and sent photos to Chris Williams. He responded quickly by sending someone out to clean off the stains. The solution that was applied had no effect on the stains, so I called again, left a message, and sent new updated pictures. I even used a power-washer the next day in an attempt to remove the stains, which also didn't work. From that point on, I did not receive any communications from anyone at Lawn Doctor after making numerous calls and emails. At the end of the second week, I finally received a short email response where Chris said he was looking into it the end of the second week, I finally received a short email response where Chris said he was looking into it and should have some answers later that day. That was the last time I have heard anything from him and now it has been more than a month. The stains are still obvious which prevents me from finishing the walkway project without sealing in their stains. I am disgusted by any business, much less the owner who damages a customer's property and walks away without a word or acknowledgement.
