As Perth houses vary so much, it is hard to give an "average" price for a 4x2, a 3x1, or a two-storey townhouse, etc. Many of Perth's older suburbs now hardly resemble what they did 20 years ago, with old houses being replaced by redeveloped duplexes and triplexes, featuring small yards, narrow side access, and often two storeys. Pricing these over the phone can be quite difficult. I can come and provide free quotes and can often give quotes from photographs sent to me. A rough guide to pricing is as follows: Normal windows (panes) under 1 square metre range from $5.50 to $6.00. If there is a fixed security screen on the window and the pane needs to be removed to clean both sides, we would normally add $6 for this per affected pane. Full-size panes such as sliding glass doors, start at $7 per pane and go up to $12 depending on the size. Screen washing, if required usually incurs an additional cost if soiling is particularly bad. Frames are always wiped clean; however, if tracks are full of gunk and a wet/dry vacuum is required, additional costs would determined onsite prior to starting. High access glass is similar to standing access glass but has additional costs attached due to the degree of difficulty with high access. All high access panes start at $7 per pane and increase depending on difficulty from there. Pool fence glass panes start from $10 per pane and go up depending on size and degree of soiling.
