A customer of mine made an interesting comment yesterday when I went to clean the windows on his place.
He's a retired fella, one of these chaps who has a garage full of hand tools from the previous century and doesnt sit in front of a computer. He paints his white picket fence yearly and replaces the posts every 5 years, because he has nothing else to do. Re-paints with primer and gloss paint his windows frames on a 'as necessary' basis. You get the picture! He likes to maintain his property.
He said yesterday, 'Since youve been using that pole business to do my windows I havent had to get up the ladder to sort out my frames this year'. I said well thats an interesting point, thanks!
He then said he reckons its because the frames get cleaned every visit the traffic pollutants dont get a chance to lift or peel the paintwork.
He's been there 33 years too, so that says something.
