What this work involves
Assess the substrate and begin with an appropriate trial area. Discuss protection of windows, planting and neighbouring materials.
- Type of soiling
- Cleaning method and trial area
- Protection and repairs
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Assess frame, reveal, insulation and internal finish as one junction.
What the drawing needs to explain
Place existing and proposed elevations side by side and add a window-opening section. Mark visible changes and elements requiring adaptation inside.
Allow for later maintenance
Keep a record of the differences between existing and renewed details. Include product information and locations of components that must remain accessible.
Which trade-off matters?
New performance and existing proportions need assessment together. A different frame profile can affect glass area, reveals and internal finishes; compare the complete detail, not just the product rating.
Cost factors for this service
Costs depend on facade material, soiling, height and protection. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for facade cleaning. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging facade cleaning?
A more aggressive treatment is not automatically better. The method should remove soiling without unnecessarily damaging the substrate.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
