Window cleaners A–Z dictionary
UK trade reference · plain English
Window-cleaning language should connect the finish with safe access and the actual surfaces included. Frames, sills, conservatory roofs and specialist stain treatment may be separate work. Homeowners should agree the service boundary, while tradespeople must choose safe methods for the site and protect other people. These definitions are not ladder, rope-access or chemical-use instructions; equipment ownership alone does not establish competence for work at height.
This A–Z combines useful technical vocabulary with links to full references where the article meets our depth and sourcing checks. An unlinked definition is intentionally kept here rather than turned into a shallow standalone page. Read a quotation against its actual scope: a familiar word is not a complete specification.

A
- Applicator
- A tool used to apply suitable cleaning liquid to glass. The material and condition should suit the surface; a dirty tool can transfer grit rather than improve the finish.
D
- Deionised water
- Water treated to reduce dissolved ions in an appropriate system. Its description is not a guarantee of a flawless result regardless of contamination, method or equipment condition.
E
- Extension pole
- A tool extending working reach. Handling, nearby electricity, public access and the actual load need assessment rather than assuming reach from ground level removes every risk.
F
- Frame clean
- A service description covering specified frame surfaces. Confirm the extent and compatible method; it does not automatically include repairs, restoration or every hidden channel.
P
- Pure-water system
- A treatment and delivery arrangement for suitable cleaning work. Water quality, equipment maintenance and correct use matter; the marketing phrase does not establish safe access or material compatibility.
S
- Squeegee
- A tool for removing liquid from suitable surfaces. Blade condition, contamination and technique affect the finish; it is not a scraper for every deposit.
W
- Water-fed pole
- Equipment delivering suitable water through a pole and brush. It can reduce some height exposure, but hoses, handling, falling equipment and electricity still need risk assessment.
- Working-at-height plan
- The arrangements for a task where a fall could cause injury. Choose suitable methods and competence rather than treating a customer's request as authority for improvised access.
