I think its simply courteous and professional to explain when things change, customers are entitled to know.
As for if they read it or not, as Chris said, maybe they will maybe they wont, but theyve been given the choice.
When I went over to WFP I didnt lose any custys and gave out an explanation leaflet.
The Water Fed Pole System
Dear Customer,
Your windows have been cleaned today using a method which is now the industry standard - The Water fed Pole System.
We are now using this technology for a number of reasons:
1). HEALTH & SAFETY -- A new legislation from Europe now limits the use of ladders. The law states that ladders can only be used when all viable alternatives have been considered, and now as The Water Fed Pole System is seen as a safer and more viable alternative for window cleaning Insurance companies are reflecting this in their premiums and terms and conditions.
2). BETTER CLEANING RESULTS -- The major advantage of pure water is that it absorbs large amounts of dirt from your windows. The process involves brushing your windows clean with pure water. As such, they will be left wet and will need time to dry naturally. This may be a little disconcerting at first, as obviously this is not what most customers are used to. However, once dry your windows WILL be clean and smear free. In addition the window frames will also be cleaned more thoroughly and on every visit.
3). ENVIRONMENTALLY FRIENDLY -- Only pure water is used, eliminating the need for detergents and chemicals.
4). IMPROVED SERVICE -- We can now reach those previously inaccessible aspects of your property. Third floor windows, hard to reach windows, skylights, conservatory roofs etc.
Please note that if your windows have been cleaned previously using detergents or chemicals it may take 2 or 3 visits using the Water Fed Pole System to remove soapy residue, this may result in minor spotting on your windows. However, please be assured that once this is cleared you will be more than happy with the results.
As a company our aim is to continue to provide a high level of service. Please feel free to contact us if you have any questions or concerns regarding the above, or any other aspect of our service.
Many thanks
I have found that most new custys simply ask 'wont it leave smears or spots?' generally thats all they want to know, but to explain how the pure water method of cleaning windows works by it evaporating leaving no residue or mineral deposits can take a little time to explain, I just give them a leaflet and get on with the job. They can read it in their time not yours.
