Windows play a huge part in many different aspects of a home or property. Not only do they boost kerb-appeal and increase saleability, but they also provide adequate ventilation, insulation, and light, and can act as fire escapes in the event of an emergency.

However, windows can be costly to repair, replace or reinstall – but without expert knowledge and assistance, it’s a difficult job to take on yourself.

Can you replace double glazing yourself?

In short, yes – there is no reason why you can’t fit your own windows. However, any windows at your property need to be installed in accordance with FENSA regulations.

By choosing a FENSA-registered company to install your windows, you’ll automatically be given a FENSA-certificate and a product guarantee. If you opt for the do-it-yourself approach, you’ll need to get in touch with your local authority so they can send someone out to sign off on your own installation and ensure it complies with building regulations.

There is usually a charge for this service, which varies between areas.

Why do I need a FENSA certificate?

FENSA is a government-authorised scheme that monitors the compliance of window and door installations with building regulations. A FENSA certificate is essentially proof of a job done right and peace of mind for all parties.

If you’re planning on replacing your windows (or doors) in preparation of selling a property, you should know that a surveyor will usually request to see the FENSA certificate during the process of the sale.

What can go wrong if I fit my own windows?

There are unfortunately a lot of variables that you need to take into account when fitting your own windows, which include:

  • Tools: Do you have the right tools for the job? Varying from the right thickness of drill bits through to the type of silicone you should be using, you’ll need to know exactly what tools you should be using.
  • Removing the existing windows: Depending on whether your old windows are wooden, aluminium or UPVC, they will require a different approach when removing them. This is often the trickiest part of window installation and carries risks such as broken glass and loose bricks and structural elements.
  • Time: Your novice knowledge will be no match against how long it takes experienced fitting teams to change windows, which could mean that you will run into delays.
  • Working at height: Where you are working on a building with two storeys or more, you’re likely to be working at height. This poses a serious risk of injury, particularly if you don’t have the adequate equipment for the job.
