i did one the other week.£45 clean price.thought id take the hit first clean.IT TOOK ME THREE HOURS!!loads of silicone that needed scraping off under the dirt!!so only £15 an hour.hard work too.
the job will only take me an hour now on maintenance cleans so £45 will be a good price for the job.
i usually charge more for first cleans.sometimes double but i made a mistake with this one!
there is a company near me who have been offering to clean windows FOR FREE FIRST CLEAN!!they plastered flyers all over telegraph poles near where i work!!
???madness if you ask me!!
