We have used the window cleaning services provided by this company a couple of times and are very pleased with them. The cleaning technicians use special window cleaning tools and harmless for the environment supplies. They access even the most distant window areas and remove the dust and grime from the inside and outside surfaces of our windows. Using ladders and other tools, the cleaners manage to scrape the dirt from every window in our flat. There aren't any drips or streaks left on our windows. The price of the window cleaning is reasonable and the quality of the service is very good.
