It takes a while to get established on a new estate and maybe like Vin says drop flyers on a regular basis .
The cheap ones will always get in first but slowly they will disappear , Have gained custys because they have seen that a do a quality job of cleaning the frames every time and doors and their trad cleaner was not touching them .
So i will always sell the fact that i am protecting their investment as white frames can become stained with dirt pretty quickly , But having said that i still see frames that are black on the tops and it just bewilders me that custy will pay over £200,000 for a house and have minging frames . Mike
