The pressure wash of the roof went okay. The process took some of the color out of the cement roof, but the owner, Elias, tested a small portion and alerted me that this was a possibility. I approved going ahead as the roof had stains and needed improvement. However, the beautiful, circular colored concrete driveway was damaged in the pressure cleaning. The owner did not test a portion of the driveway and did not tell me that it would remove the color. If he had, I would not have had the driveway cleaned. When I contacted the owner about the situation, he said he could not assist with the restoration or be responsible. To me, this is like taking a your nice suit to a dry cleaners and after the suit is damaged, the cleaner saying they can't be responsible because their process damaged your suit. The entire point of having the driveway pressure washed is to improve the appearance. Below is the email exchange. You can decide if this is the type of service you want. --- Me: Unfortunately, there was quite of bit of color that was removed from the driveway. Both the main part of the driveway and the darker border were impacted. I?m disappointed with this result, as the driveway was significantly damaged by the cleaning. I knew that was a possibility from the roof, however, I did not want to remove the color from the driveway. What do you recommend? Elias: Wow, that's not good. The other tenants did a poor job staining it. Well, the only alternative is to seal it again, however, Sherwin Williams has a good sealer call Tough Guard. Me: Does Tough Guard restore the missing color? Elias: you need to pick a color that's close enough to existing one. The prior owners most probably used Behr concrete stain and Home Depot products are mostly a domestic low in solids type of product, so it doesn't last very much. Me: I don?t know anything about this product or this process. Since the removal of the color is a result of the pressure washing, it would be helpful if you assisted in the restoration. You were diligent in testing an area of the roof and seeking my approval, which I appreciated. However, the same attention was not given the driveway. Either too much pressure or brushing was used, which removed the color. Please make this correct. You have excellent reviews on Angie?s List and I selected your company for that reason. You have stood behind your quality work, which is why I chose you. Elias: Sorry, Contractor cannot be responsible for old surfaces that the stain or paint peel off due to pressure cleaning.
