Window Installer FAQs

How can I find out how energy efficient my new windows will be?

All new windows come with an energy efficiency rating from A to G. A is best, while G is the lowest rating. Anything above C is considered good, but these days most companies will be able to supply you with A-rated windows to maximise your energy efficiency.

Should I get all my windows replaced at once?

You don’t have to, especially if you’re on a budget. If you’re only replacing some, it’s a good idea to get all the windows on one side of your property replaced at the same time, so they all look the same. Be aware, obviously, huge savings could be had by having a number of windows replaced at the same time.

how much are new windows?

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.

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

Should I use a Fensa registered installer?

Using a Fensa registered installer isn’t compulsory but it helps to protect you from cowboys and rogue traders. It will also make life a whole lot easier in regards to Building Regulations. Replacement windows must meet a certain energy efficiency rating and once fitted you need a certificate to show your installation complies. By using a Fensa registered company they’ll issue this certificate, otherwise you’ll need the council to look at the new windows.

how to fit a double glazed window?

Did you just purchase a double glazed window and confused about how to have it installed? Fitting the window yourself can be quite easy with the help of this step by step guide. However, if you lack proper training or experience, we’d recommend you reach out to a trustworthy professional who can guarantee the best results for help. That said, now let’s take a look at the process.

• Remove the old windows by detaching the old beading and glass window safely. Then make some interval cuts using a hand saw before using a crowbar to pry it out.

• Cut the external double glazed window seal. Once done, take a measurement of the window area’s width once empty. Then transfer the measurement to the window sil to face outside and cut using a handsaw.

• Seal the window sil. Add a bead of clear silicone along both inside lip as well as the centre to seal the sil.

• Screw the double glazed window to the sil. Position the window on the top of the lipped section that was siliconed. Then pre-drill them together and screw in three places. You should make sure the screws do not go totally to the sil’s bottom.

• Install the double glazed window. After successfully screwing the double glazed window to the sil, you can now fit in the double glazing. Make use of packers to make sure it’s even in the slot.

• Screw the uPVC window to the wall. If you’re happy and satisfied with the position of the window, you can then pre-drill through the frame of the window and the brick wall. Once done, simply screw it in place using masonry screws or Spax screw as they do not require crawl plugs in bricks.

• Seal around the window. To do this, simply fill any gaps with expanding foam, wipe out the excess and seal with silicone.

Will double glazing increase my property’s value?

These days, buyers expect homes to have double glazing. People recognise the benefits of installing double glazing, so if you don’t have it installed you should consider it. You’ll increase your property’s value and give it a better chance of selling faster, since single glazed properties are also more likely to have problems with damp and mould which could put buyers off.
