Fitting Secondary Glazing— Costs and Other Considerations

Material Costs, Labour Fees and Time Frame Estimates for seondary glazing

If you wish to fit a secondary glazing, a pane of framed glass will be fitted into your existing windows. This is different from double glazing where the current window will have to be removed and replaced. It helps with the sound and energy insulation of your home. On top of that, it is also a much cheaper alternative to double glazing. It’s a great alternative to consider especially when double glazing can’t be done especially if your property is a listed one.

Aesthetics-wise, people will love the fact that secondary glazing looks quite discreet, especially if used along with an aluminium frame. It’s also easy to get secondary glazing installed. If you are a keen DIY-er, you’ll find that this is one project that would be easy enough for you to pursue. You can even buy DIY kits, which should help you save considerably on costs.

DIY Tips and Tricks

You’ll find a variety of secondary glazing units that are ideal for DIY out there. What’s even better is that they can get delivered straight to your home with the parts already pre-cut to the appropriate sizes, fixtures and fittings included. They’re generally very easy to install and if there’s a need to remove them, the process involved is relatively easy as well.

Start by getting the existing window measured. Once you have the necessary dimensions, you can proceed and place an order for the secondary glazing. Once you get the secondary glazing delivered, the next thing you need to do is just lift it into the appropriate position and have it packed around so it will be square and level. Once done, the secondary glazed panel will then be put into place. Just use screws into the fixing points which should already pre-drilled around its frame. There should be little to no mess or disruption to your entire home when adding secondary glazing. You can expect the job to get completed in a matter of a few hours.

When fitting a new secondary glazing, the new frame might make the existing frames look grimy. It isn’t a bad idea to have the wood surround and windowsills of your existing windows cleaned up and redecorated before adding the secondary glazing. A fresh gloss coating to the woodwork can go a long way. Getting new blinds is also something you might want to consider too as there is a very good chance that the new blinds will only get in the way of the glazing that you’re fitting in.

Ideal for Listed Properties

If you happen to live in a listed or period building, you will likely not be allowed to install double glazing to your windows. For those instances when securing permission for the installation of double glazing is next to impossible, your alternative is to fit secondary glazing instead. It won’t require any permission and the installation process is easy enough to do by yourself. Even better is the fact that it isn’t going to alter the overall look of your building whilst still providing you with all the benefits that a double glazing window offers—  including efficient thermal insulation and noise reduction.

Magnetic Secondary Glazing

If you’re looking for an alternative to the regular secondary glazing panels, you can go for the magnetic ones. They are less expensive but offer the same benefits in terms of noise and heat insulation. Instead of screws, it makes use of magnets to put it in place onto the current window frame which means that there aren’t any installation costs for you to cover. Since the panels are just attached via magnets, removing them is quite easy to do if there is ever a need for you to in the future. The only downside to these types though is that it isn’t possible to open them unless you completely remove them from your existing window.

Issues with Secondary Glazing

Before installing, it helps to research their possible downsides. For instance, you might have to deal with more condensation when having these panels installed due to the fact that they are not sealed, just attached to your existing window. When there is high humidity in the air, it can condense onto your window glass. The existence of a secondary glazing pane might make it hard to wipe the condensation off unless you fully remove them. There’s also no vacuum between the glass panes so secondary glazing cannot insulate as efficiently compared to double glazing. In addition, these problems can be further exacerbated if the secondary glazing isn’t properly installed. This is why it’s advised to always rightly seal the window frames when installing your secondary glazing. Draught proof strips are usually good enough to do the job, especially if there is a need to get the surface contours properly hugged.

Secondary Glazing Fitting Costs

The average costs for materials involved in the installation will be dependent on the number of windows you have. The specific type of secondary glazing you’ll choose will also affect the price involved. Expect to pay more for secondary glazing for sash windows as they tend to be more expensive compared to horizontal sliding ones. Secondary glazing may cost around £100 -£200 per piece. If you’ll ask a window specialist to take care of the installation, they will generally charge £150 for a day’s work. However, since they usually work in pair, expect the costs to be around £250. Expect the job to be completed in 2 days, although the length of time for completing the installation can be affected by the number of windows that need secondary glazing and their sizes.

Cost Breakdown

For installing to a total of 12 windows, expect the costs to be around £2000. Of that, £1500 goes to the materials, and £500 will cover the tradesmen fees.
