Office and Window Commercial Cleaning

Professional Window Cleaning by Alternative Cleaning Limited

Water & Squeegee

This method is generally used for ground level windows and internal windows and office partitioning.

A degreasing agent is added to water, and a soft handle is dipped into the resulting solution and used to scrub glass. A squeegee is then used to sluice dirt and water mixture from glass.

Water-fed Poles (Reach and Wash)

This method used for all outer windows beyond ground level as well as professional signage, canopies, fascia’s etc.

Any of a variety of types of telescopic poles, fitted at the upper end with a brush and water jets, fed either from vehicle-borne tanks of deionized water or by on-site production of deionized water using a domestic or commercial water outlet. The water is filtered by either a two-stage or three-stage filtration process,
involving a carbon filter, and two de-ionization filters, or a carbon filter, a reverse osmosis membrane filter, and a de-ionization resin filter.

The filtered water contains a TDS (total dissolved solids) of less than 5 ppm. (Parts per million.) The brush is used to agitate the debris off the window, while spraying water, and then the brush is lifted a few inches from the glass to rinse the glass with the pure water jets. Fan jets are used for hydrophobic glass, and “pencil” jets are used for hydrophilic glass. The de-ionized water is lacking in ions, so it will pull solids off the glass and dissolve the solids into the water, aiding in the cleaning process. Because there are no solids dissolved in the water, the windows dry clear without water spots. Water-fed poles vary in length. Our longest poles are about 70 feet, and can reach up to six storey’s. Water-fed cleaning is also referred to as pure water cleaning.

Ladders

Used on first floor levels where another person acts as a foot stopper to the base.

Ladders ranging in size from a single step to the extent (and beyond) of local regulations are used to access windows for cleaning purposes.

Supported Scaffolding

Not to be confused with suspended scaffolding, these are temporary work platforms typically erected from a lower level to gain access at height.

Aerial Work Platforms

Machines variously configured and powered, designed to deliver our workers to otherwise inaccessible areas such as large internal reception areas, Churches and railway station canopies.

Suspended Platform or Cradle

Not to be confused with supported scaffolding. Devices designed for ascent and/or descent via wire rope by mechanical or manual means.

  • Boatswain’s Chair (Bosun’s Chair): A boatswain’s chair is a single-person seat designed for controlled descent of rope. Often referred to as “rope decent systems” (RDS), these are typically anchored to a roof structure, counterweight configuration, or connecting points designed for the purpose. Note: These are always temporarily installed for the purpose of access. However, their anchor points can be either temporary or permanent.
  • Suspended Platform: An access platform for one or more workers with manual or motor driven devices for raising and lowering via rope. Platforms may be fitted to high rise buildings or skyscrapers, or assembled from components to suit architecture and nature of work being performed. Note: These can be either temporary or permanent. Both having their own unique governing codes and regulations. Permanent suspended platforms are often known as building maintenance units (BMU) and their platforms are also known as gondolas in.

Alternative Cleaning Limited have their own professionally trained window cleaners as well as using the services of its Partner and Sub-Contracting window cleaning Company who in turn have the necessary training and certification to carry out their duties professionally and with efficiency.
