Double Glazing London Greater London (SW1): Double glazing can boost security, increase your home's energy efficiency and reduce noise levels. Double glazing refers to the way a window is made using twin panes of glass with a gas filled medium, commonly argon, between them. Acting like an insulating material, this inert gas delivers outstanding sound proofing and thermal qualities for any property or home.

The time may have come to think about upgrading your windows, if you already have older double glazed windows in your house in London but have been living with issues, such as draughts or condensation between the panels.

Double Glazing London Greater London (SW1)

Condensation occurs in the space between the window panes when holes appear in the seal around the glass and warmer air enters from inside the property. As the warm air comes into contact with the colder exterior pane of glass, moisture forms, with condensation as the result. If this is happening fairly often it's time to change your current windows.

An immediate improvement in the warmth and insulation from outside noises will be experienced if your home in London has single glazing and you swap the for double glazing. You may also increase your property's value (if you opt to sell), by upgrading to double glazed windows.

Double glazed casement windows have hinges on one side and can open inwards or outwards. This gives a good amount of airflow in the summertime and allows for easier cleaning. Tilt and turn casement windows are also available for use where security is vital. Tilt and turn double glazed windows have an extra hinge to be able to open slightly. Improved security is the result, because to let a fresh breeze to enter the room, they can be locked firmly in place when partially open.

To suit a period home in London, there are also options for double glazing sash windows with a traditional appearance. There are double hung versions where both of the sashes can be moved, and single hung versions where only one sash can be slid open. The sash windows of yesteryear were renowned for their poor standard of energy efficiency, however this issue has been largely reduced with contemporary double glazing models, and in terms of thermal losses, there's hardly any difference between sash and casement windows nowadays.

Bay windows look fantastic and can bring a sense of space to a room. If your property in London already has a bay window, you could replace it with an equivalent double glazed unit.

You must be able to find the CE mark displayed on any modern double glazing that is fitted in London homes. This CE mark should be visible on the inside of the sealed glass panel and on the frame, and proves the quality of both the frame and the glass. For all doors and windows produced in the British Isles and the EU, the CE logo is a necessary requirement. If CE approved materials aren't used by your double glazing firm in London, they could be using low quality components and making their doors and windows using less rigorous standards. Even though these lower quality products may be OK in certain situations, you should always demand guaranteed double glazing with CE approval for your property in London.

Once you settle on a double glazing company in London and are happy with the price quoted, your new windows will be made-to-order. Subject to the style of window, your frame type, the amount of windows and doors you require and the opening options, this may take anywhere from a few days to several weeks. The time frame for installation can then be arranged and must include any need for applying for planning permission if required.

Planning permission may be necessary if your home is in a conservation area, is a listed building, is close to a National Park or has a restrictive covenant. A trustworthy double glazing company will be happy to advise you on any restrictions and will likely have already conducted work in the London area, and will know the legal requirements and necessities.

The installation time of your double glazing will be determined by how many windows are being installed. A standard double glazed window can be installed in around 3 hours. Removing the existing window will be included in this time frame, as will squaring up the hole that the new window sits in. With very little disruption to you, an average home can be completed in a couple of days.

Membership of such associations shows that the company is experienced, qualified and complies with building regulations, but does not necessarily guarantee that nothing will go wrong during the installation of your double glazed windows.

In addition to any company warranty, these industry bodies also offer some form of guarantee or compensation schemes, to ensure that there's an independent arbitration between the 2 parties if there is any disagreement. Needless to say, the vast majority of double glazing installations in London are completed with 100% satisfaction, however it is good to know that help can be sought if it's required.


Even if everything has gone to plan during the installation there could be questions or advice needed afterwards. Your double glazing should come with a warranty of up to 10 years, and many double glazing firms in London will also offer a callout and troubleshooting service in case anything goes wrong with your new windows or doors. It is good advice to check this out beforehand to find out if there's a free repair and callout period as part of their guarantee.
