Tom's Power Washing killed $500 worth of plants Kutztown PA

Before the company was hired I asked if their method/products were safe for plants. They assured me they were. Within 2 days of the siding being cleaned plants next to the house in the area they cleaned began to die. There were also 2 circles of dead glass where they put their buckets.

When I complained they first said the plants were fine the day after they cleaned. A few days later they said the plants were dead before they did any work. You don't have to be a botanist to know that both those things can't be true. In fact, both are false. They refused to take any responsibility and we are left with having to replace over $500 worth of foundation plantings including small bushes and flowers.

They tried to tell me this had never happened before. But instead of trying to figure out what happened and how to reverse the damage they just pretended it didn't happen. However, I have before and after pictures to prove my claim.
