 Domestic window cleaning

Your windows will be cleaned using the very latest in window cleaning technology - water-fed poles are used.

Pure water is pumped to a soft brush and this gently and effectively removes all dirt and contaminants from your windows and frames. The windows are left to dry spot-free and smear free - and cleaner than they have ever been before.

Quite apart from leaving the window cleaner than traditional methods, there are very many other advantages to the water-fed pole:

• windows and frames are cleaned at the same time
• windows stay cleaner for longer
• windows that are difficult to reach by ladder are usually easily reached by pole.
• increased privacy for upper floors
• no damage to your garden from ladders
• safety

Service 
When we clean your windows, we:

• brush cobwebs and loose dirt from the surrounding masonry, if necessary.

• gives the frame a thorough cleaning getting rid of cobwebs, loose dirt, bird lime etc, so the frames will gleam like new.

• clean the window thoroughly getting rid of all surface dirt and contaminants and getting rid of soap deposits left in the seals.

• clean your front door and the surrounding frame.

The end results is that the entire facade of your house will look better because you'll have shining window glass in gleaming frames.

Frequency
We offer a regular, four-weekly service to all customers.

In exceptional circumstances we can offer a one-off clean at double the standard price. This is because a first clean always takes very much longer than a maintenance clean.

Prices
Each individual job is priced differently because each house has its own individual character. The following will give you some idea of the price range for your property.

Prices depend on the number of windows to be cleaned and access issues. For example, some windows over conservatories are very physically demanding and time consuming to clean. They may therefore charged at a higher rate.

Bungalow from £5 to £10 depending on the number and size of windows.

Older 3-bed semi - £10 to £13

Newer 3-bed semi - £12 to £15

Older 3 or 4-bed detached £12 to £18

Newer 3 or 4-bed detached £15 to £20

Larger properties £25 and upward.

Gutters are designed to prevent rainwater from damaging the exterior and the foundations of your property. In order to do their job, they must be clear of leaves and other debris.

Blocked gutters can become heavy from the extra weight of dirt and water which can then cause your guttering to pull away from your fascias. In some cases they can even fall from the house completely. Water overflowing from blocked gutters can run down walls causing them to become damp or  permanently stained. It can even damage paths around your property and cause problems with foundations.

Gutter clearing and cleaning is one of the most important exterior maintenance jobs for a property, and should be carried out once a year.

We uses a high-powered vacuum system to completely remove all debris from your gutters. It will leave your gutters clear, clean and free flowing and leave your property clean and safe.

The gutters, facia and soffits are then cleaned to completely rejuvenate the appearance of your house.

We can clean your driveway, patio, decking etc using a high-powered pressure washer and get it looking like new again.

As with the pure water technology, we don't use any aggressive or polluting chemicals with this method of cleaning. It is the ability of the high pressure water to get underneath the dirt and simply float it away from the surface which makes the cleaning so effective.

Because we use a proper professional machine (as opposed to a low-powered domestic model) we can fine-tune the water flow and pressure to get the best results. And the power of the machine combined with the experience and training of the operator guarantee you the best results with no fuss and mess.

Rather than writing a lot more words, we'll let these pictures do the talking ...

Pure Water
Pure water is the best cleaning agent for glass for two very good reasons.

• First of all, pure water is an excellent solvent. It will dissolve most minerals and all organic compounds that are likely to contaminate a window.
• Secondly, when pure water evaporates, it evaporates completely and leaves no spots or smears behind.

Have you ever breathed on a pair of glasses or on a mirror to clean the surface? Did you notice how clean the surface polished up and how the moisture dissolved even grease from finger marks? If you have, you have experienced the cleaning power of pure water.

The moisture that condensed from your breath was absolutely 100% pure - and it was this pure water that dissolved all the contaminants on the surface so you could polish them away.

It is the purity of the water that makes it such a good cleaning agent.  Pure water is a very powerful solvent, and will dissolve almost all minerals and organic compounds to some extent.

Here's a experiment you can try for yourself.

1 - Take a small mirror and clean it by breathing on it and wiping away the moisture with a clean cloth or tissue.

2 - Put the mirror in the fridge for a minute or two.

3 - take it out of the fridge and breathe heavily onto the the mirror so you get a lot of condensed moisture.

4 - Leave it to dry naturally.

Notice how the mirror dries perfectly clean. The moisture evaporated and didn't leave any residue behind. The moisture that condensed on the glass surface came from water vapour in your breath - and it was 100% pure water with absolutely zero mineral content. It evaporated leaving the glass surface absolutely spotless.

To summarise: These two things are the secret to cleaning with pure water:

1 - Pure water is an excellent solvent and either dissolves or washes away contaminants from a glass surface.

2 - Pure water evaporates and doesn't leave any residue.

Very pure water is found in nature in raindrops and in dew - and both are made by condensing water vapour. All other liquid water found in nature, standing or flowing, is impure to some extent. This is due to the pure rain or dew water (i) dissolving minerals as it passes over soil or rocks or passes through the Earth and (ii) dissolving organic materials. This water also has solid contaminants suspended in it in the form of very fine dust and microbes.

The water used for window cleaning is the same grade of water used in hospitals, pharmaceutical laboratories and research laboratories for cleaning glassware.

It usually purified using a process called reverse osmosis - of which more later. This is a much cheaper method of purifying than distilling.

The window washing process
Windows, frames and sills (also spelt cills) are washed by pure water sprayed through a specially manufactured brush. Any surface contaminants on the glass are loosened by a combination of the brushing action and being dissolved or suspended in the water. They are then simply washed away. The windows are then rinsed and left to dry naturally.

There are FOUR things to notice about the way that he works:

1 - He cleans the entire window including the frame and the sill.

2 - He is very careful to rinse the window well after the washing. A thorough wash followed by a careful and complete rinse is the key to success with a water fed pole.

3 - He is using a fairly low water flow - probably about 1.5 litres per minute.

4 - He leaves the windows to dry naturally. Because the water is pure and doesn't contain any dissolved minerals, the windows dry to a perfect, spotless and streak-free finish.

The brush is mounted on a pole so even high windows can be cleaned from the safety of the ground.

It also gives a very concise and accurate explanation of how the system works and implications for safety.

The pure water is  pumped from a tank to the brush. It is then brushed onto the window frame and glass where it quickly loosens and washes away any surface dirt and dust. Difficult and tenacious contaminants like bird lime and finger prints are removed by gentle scrubbing with the brush. Then the brush is held away from the glass and the water sprays onto the window and rinses the surface. The window dries absolutely spotless - since there are no dissolved solids to leave spots!

The water is stored in a large tank either mounted in a van or a trailer or plastic barrels in a trolley-based system. The flow rate is usually between 0.7 and 2 litres per minute.

Water purification
The water used to clean your windows is exactly the same purity as water used to clean glassware and other articles in operating theatres and chemical and pharmaceutical laboratories where cleanliness is crucial.

You probably know that the water delivered to your tap can be soft or hard, depending on where you live. Most of the UK has hard water. The hardness is due to dissolved minerals which water picks up as it percolates through the Earth's rocks into the aquifers. These are referred to as dissolved solids. Rainwater is very soft since it hasn't picked up any solids as it hasn't yet percolated through the Earth. This is why it is so good for washing your hair!

The water purity is expressed in parts per million (ppm) of total dissolved solids (tds).

Tap water is typically between from 60 ppm (soft water) to 200 ppm and above. Pure, uncontaminated rainwater will typically be between 2 and 6 ppm due to it catching dust as it falls through the atmosphere.

Water used for window washing is 0 ppm tds.

Tap water is purified, usually in five stages:

stage 1 - particle filter

stage 2 - carbon filter

stage 3 - carbon filter

stage 4 - reverse osmosis (RO) unit

stage 5 - de-ionisation (DI) unit.

Sometimes, in very hard water areas, a water softener is used before the standard filter.

When two water (or other solvent) volumes are separated by a semi permeable membrane, water will flow from the side of low solute concentration, to the side of high solute concentration. The flow may be stopped, or even reversed by applying external pressure on the side of higher concentration. In such a case the phenomenon is called reverse osmosis.

If there are solute molecules only in one side of the system, then the pressure that stops the flow is called the osmotic pressure.

Reverse Osmosis (RO) was invented in 1959 by Prof Reid of the University of Florida, and was put into practical use by Sidney Loeb and Srinivasa Sourirajan. It is a process which removes both dissolved organics and salts.

Feedwater is pressurized and flows across a membrane, with a portion of the feed permeating the membrane. The balance of the feed sweeps parallel to the surface of the membrane to exit the system without being filtered. The filtered stream is the permeate, because it has permeated the membrane. The second stream is the concentrate because it carries off the concentrated contaminants, rejected by the membrane.

Because the feed and concentrate flow parallel to the membrane and not perpendicular to it, the process is called “cross flow filtration”.

Depending on the size of the pores engineered into the membrane, cross flow filters are effective in the classes of separation known as Reverse Osmosis, nano filtration, ultra filtration and micro filtration.

Cross flow membrane filtration allows continuous removal of contaminants which in normal flow filtration would blind (plug) the membrane pores rapidly, in conventional systems. (GrahamTek changed this technique successfully)

RO removes most organic compounds and up to 99% of all ions.

This information is taken from:  www.bionicsro.com/what-is-reverse-osmosis.html.

• There are no aggressive chemicals used in the cleaning process - only pure water
• There are no aggressive chemicals used in the purification process.
• The purification process uses very little energy.
• There are no harmful by products created by either the cleaning or the purification process.

Many of those who use rainwater claim that it is even better than purified water for cleaning, though there is no known scientific reason why this might be so.

Health and safety
Water-fed pole is the ideal way of cleaning windows in buildings of up to six stories since it can almost completely eliminate the need for ladders. Where ladders are used, they are used for access and not as work stations.

Environmental issues
Pure water is completely neutral and therefore safe. The purification process is also very environmentally friendly since it (i) uses very little energy, (ii) doesn't use any aggressive chemicals and (iii) doesn't produce any noxious waste materials.
