Double Glazing

Double Glazing Project Timeline

When you’re planning to get new or replacement windows, it’s important to know how long the work’s likely to take. This lets you plan your double glazing project and get it completed by any deadlines.

We’ve come up with a sample timeline for your double glazing project. Make sure you only treat it as a general guide – your windows could take less or more time to install.

How long will a double glazing project take?

Research: 1 week

It’s important to spend a good amount of time looking for the right tradesperson for your project. During this stage, you’ll need to research companies and request quotes. If you decide to use our service, our companies will usually contact you within 48 hours of you submitting your online enquiry.

After you’ve found some double glazing installers, you should spend a couple of days getting quotes and selecting the best one. If you’ve found them through our service, you can read reviews from other customers on their profile page. And if you want an installer who can self-certify compliance with building regulations, make sure they’re registered with a Competent Person Scheme, like FENSA or CERTASS.

Measuring and manufacturing: 4-8 weeks

Once you’ve found the right double-glazing installer for you, they’ll need to know the exact sizes of your windows and how many you need. Once they know this, your windows can be made for you. How long it takes for your windows to be made can vary a lot – but it generally takes between 4 and 8 weeks for them to arrive.

Removing your old windows: 1-2 days

Once your new windows have arrived, your double glazing installer will start by removing any old windows you’re replacing. How long this takes will depend on how many windows you need removing, but it’s unlikely to take more than 2 days.

Fitting your new windows: 1-2 days

After your old windows have gone, your new ones can go in. Again, how long it will take depends on how many new windows you’re getting. For the average double glazing project, removing and fitting windows shouldn’t take any longer than 3 days.

Total time: 5-9 weeks

So now you’ve got a rough idea of how long your double glazing project will probably take. To get going on your project, complete our form below. We’ll connect you with up to 4 local double glazing installers.
