Window Installer FAQs

How much could I save on my energy bills if I install double glazing?

As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.

How to remove a aluminium double glazed window?

Removing a double glazed window can be quite labour intensive. If you decide to try it yourself, make sure you give yourself plenty of time, and wear gloves and goggles.

Begin by unscrewing all opening windows at the hinges and removing them. Then take away the beading and putty around any fixed panes and take them out too.

Once you’ve removed all the glass, use a saw to put angled cuts in the frame, and a bar and hammer to remove it in sections. You should remove the sill if you’re going to replace that too.

Finally, cut through any screws holding the frame into place with a hacksaw.

how to repair or replace a double glazed unit?

Are you about to purchase a double glazed unit and wondering how to go about the replacement project? If yes, then you’re at the right place. Firstly, it’s advisable to hire the services of a reliable professional who can guarantee the best results for help especially if you lack proper training and experience in the field. However, we’ve put together this step by step guide to provide you with a detailed information about the double glazed unit replacement process. Let’s get started!

The tools and materials you require for the project includes tape measure, hammers, nail punch, scraper, spacing blocks, non-hardening butyl putty, high-security glazing tape rolls and beading tacks.

• Work out the glass size required. Simply use the tape measure to measure from frame edge to frame edge while also taking note of the thickness.

• When about to order, inform the glass merchant that the measurement provided are frame-tight. This will make him reduce the dimension a little bit, mostly by 5mm for clearance.

• Remove the beading and ensure to support the glass while doing so. If the glass units are fitted in wooden windows, you may need to cut the putty-based compound they’re normally sealed with to remove the glass.

• Lay out the beading in the window’s shape to make for easier refitting later on.

• If you’re working on wooden frames, wipe out all traces of excess installation compound using a scraper and clean the rebate with a soft brush.

• Trial fit the double glazed windows to ensure they’d slide into the frame without being forced.

• Plastic frame windows are usually in between a pair of gaskets, you should replace this with a hight security glazing tape. While for a wooden frame, simply apply strips of flexible non-setting butyl putty or high-security glazing tape on either sides of the glass.

• Install and centralize the glass in the frame.

• Press the nail wooden beading or plastic beading back into place.

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.

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.

What happens if I have problems with my new windows?

Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.

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.

How to fix a cracked glass window?
You can end up with a cracked glass window in a few ways. The most common one is when a rogue stone in the lawnmower hits the window or someone’s cricket or tennis game goes wrong and you end up with a ball through the window. Youi often end up with a ‘bullseye’ type crack that expands out from the point of impact. You can also get pressure and stress cracks from intense fluctuations in pressure and temperature. Unfortunately, there’s no way you can permanently fix cracked windows without replacing the entire sealed unit. An installer can replace a cracked glass window in less than an hour simply by taking out the sealed unit (the two panes of glass in double glazed windows) and replacing it with a new one. It costs an average of £110, but you could try to do it yourself for around £55. But what if you can’t get an installer to fix your window straight away? There is a DIY method you could try. As a temporary fix for your glass window, you can use a solvent-based adhesive like epoxy which will keep the glass intact and prevent further damage. You’ll also need:
  • Washing up liquid
  • Glass cleaner
  • A lint-free cloth or rag
  • A putty knife
  • A paper plate
  • Acetone
First, you’ll want to clean the glass using the washing up liquid and a damp cloth to remove any dust or oils. Leave it for a few minutes to dry, then create a mixture of epoxy by combining the hardener and the resin and stirring it on a paper plate. Using the putty knife, spread the mixture on the cracks, making sure you press gently to fill them. Leave it for at least 5 minutes to dry, then get rid of any excess by using some acetone on a dry cloth. Clean the window using some glass cleaner and another dry cloth, and you should have a temporary fix!
