Check the substrate
Brick, stone, paint and glass respond differently to cleaning products and equipment. An appropriate specialist should assess the material and any vulnerable joints or finishes.
Test the proposed method
Agree a test area where appropriate and the expected result. Complete removal without colour change or surface effects cannot be assumed in every situation.
Compare complete work
Include access, protection, cleaning, waste handling and any subsequent surface treatment. Ask how adjacent surfaces and the surrounding area will be protected.
Frequently asked questions
What should I include in a quote request?
Describe the work and include the town, postcode, photographs, dimensions and any available drawings. Add your preferred start period. Larger projects need a site visit to establish the scope and price.
