Name the coating being supplied.

Windows · Blaine, Washington
Window replacement in Blaine described as self-cleaning should identify the actual factory coating and the conditions its cleaning process needs. That description should not be taken to mean every mark disappears without further care.
Tell the supplier where the glass will be installed, including any roof or shelter over it. Ask how the supplied product’s daylight, water exposure and care guidance relate to that opening before choosing it for reduced cleaning.

Window replacement
Ask the supplier to explain the named coating’s process and limits for the proposed opening. Keep its factory specification and care instructions together so a marketing description does not become a maintenance-free promise.
Have the order identify the actual glass product and coated surface. A spray or added film should not be assumed equivalent to a factory-applied self-cleaning product.
Show the opening and any overhang or proposed cover to the supplier. Ask whether the location supports the selected product’s documented process.
Request instructions for persistent deposits or handling marks and identify who can assess an uncertain condition. Reduced routine cleaning does not remove the need for suitable access and product-specific care.
Before work begins
Use the City’s residential building resources to check the actual replacement, including any changed opening or associated wall work. Keep the selected glazing information with the project package where it is needed; a self-cleaning label does not determine those construction requirements.
