How we clean slate
We explain the process
Before any work starts, you know exactly what we'll do and what to expect.
We protect the property
Plants, gutters and copper get noted and protected. Landscaping is rinsed the whole time.
We soft wash from ladders
Low-pressure treatment applied from ladders. No one steps on the slate.
Weather finishes the job
The slate is not rinsed. Rain clears the dead growth over the next 6 to 8 weeks.
