After fitting your new windows, your installer should take away and dispose of your old windows. If you want to keep them, just let your installer know before they start work. The UPVC frames are melted down and used on the unseen parts of new windows. Aluminium frames are re-smelted and wooden are broken down and used as chipboard.
Are you about to replace your old windows and wondering just how much it’ll cost to have a new one fitted? If yes, then you’ve come to the right place! The question is a very straight forward one, however a direct answer can not be provided as determining window prices for a replacement project can be a very tricky challenge. With a plethora of influencing factors that can play a key role in the price of both materials and labour to be used, it could be extremely hard for a window installer to provide a cost estimate without paying you a visit beforehand.
The factors that can go a long way in determining the price of your new window includes the size of the window, frame material, style chosen, your location, rates charged by the window installer (these rates can be different from an installer to an installer, so it’ll probably be in your best interest to compare quotes to identify the most competitive price) as well as the type of glass required.
Generally, for a small flat featuring four windows, the average cost for new windows would be between the range of £2,100 to £2,300. This range provided covers the cost of double glazed uPVC casement windows as well as the installation price. In the same tone, a home with up to 8 windows will have an average cost for window replacement between the range of £4,400 to £4,600, wile also taking into account the installation price. Whereas a house comprising 10 windows could begin at an average cost of window replacement between the the range of £5,200 to £5,500, and a 15 window home will be between the range of £8,400 to £8,600. it should be noted that the aforementioned figures only include the standard number of windows with a uPVC frame and the installation cost.
If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.
Some properties are unable to have double glazing, especially those in conservation areas or listed buildings. To counter this problem and still benefit from a warmer home and cheaper bills, secondary glazing is an option. Secondary glazing is a second pane fitted inside your original window. Secondary glazing will still save you around £105 yearly.
