So you’ve got a few quotes. You got a price you liked, from a local company with a good reputation. It’s time for installation. What happens now?

Double Glazing on The Web knows all there is to know about double glazing installation. Our team have spent years working within the double glazing industry and have built a wealth of knowledge on all things double glazing. Let us fill you in on what to expect with our double glazing installation guide.

Window Installation
You’ve chosen the colour, the handle colour and you’ve decided to go with A-rated windows with maximum security locking systems. The next step, installation.

When the fitters arrive, they will first make sure they have safe access to the window. Don’t worry about moving heavy furniture; they will move what they have to and carefully prepare the working area for a clean and tidy installation.

You’d be surprised at what fitters have to work around from day to day, so you don’t have to worry. After they’ve checked access is OK, they will lay down their dust sheet.

All good double glazing installers will have a dust sheet, however it is a good idea for you to check before they start that there is one laid down.

If you’re having a sash window, for example, years of dust builds up in the sash box. This dust goes everywhere. If they don’t have a sheet, either ask if they can get one or give them your own if you have one from previous decorating or DIY improvements. You don’t want your furniture or floor covered in dust.

Removal of Old Windows
Assuming you are having the whole window replaced, they will double check the measurements of the new frame, then all being well; take the old one out.

The new frame is inserted into the aperture and bolted into the concrete. The fitters will check with a spirit level that everything is even, then they will move on to fit the glass sealed units.

Once the window frame is firmly installed into the brickwork, the installer will carefully place the glass sealed unit into the aperture and then proceed to gently fit the beads to enclose the glass in the frame.

They may use wedges to ensure a snug fit between the glass and internal uPVC frame however the surveyor would have ensured the glass was ordered perfectly to the size of the window.

Ensuring The Perfect Finish
Once the window has been installed, the fitter will silicone and trim from the inside and outside to give the window a perfect finish. They will use colour matched trims and sealants so that it is not noticeable where the window meets the brickwork.

It is often worth checking over the perimeter of the window installation to ensure that there are no visible gaps in sealant and the finish is as immaculate as you would expect.

Time To Tidy Up
Once the installation is complete, the installers should take away their tools, tidy the working area and often hoover the floors to leave your home as spick and span as when they first arrived. Be sure to check the working area before they leave to ensure it is left in a clean and tidy state.

If there are any moving parts or special features they will test them and show you how they work. Finally, with a smile they’ll be off into the sunset.
