Double Glazing Window Installers Near Me

Are your windows in need of replacing? Double glazing is an incredibly popular option for homeowners who are looking to upgrade their existing windows.

Compared to single glazing, double glazing is far more energy efficient. That’s because double glazing consists of two individual panes of glass that are filled with a gas such as argon. These components work in tandem to deliver thermal insulation that is far superior to single glazing.

Double glazing can be found in a variety of window styles and frame types. Overall, there is a lot of choice for homeowners. Having double glazing installed can greatly increase the look of your home, as well as its energy efficiency.

If you are on the hunt for double glazing, we’ll help you find trusted installers in your local area.

Choosing your perfect professional

What are the benefits of Double Glazing?

Approximately 25% of any home is made up of window space. So if your windows are performing poorly, they could be letting out a lot of heat. As a result, your energy bills will be higher because the heat is simply escaping through them, rather than being retained in the property. Double glazing will greatly improve the energy efficiency of your home. It can also provide much better protection against outside noise, especially if you live near a busy road.

Compared with single glazing, double glazing provides better security too. After all, a strong frame and two panes of glass are much tougher compared with a single pane of glass. Many double glazed windows also have sophisticated locking systems that add another layer of protection for homeowners too.

Whatsmore, double glazing can greatly enhance your home’s kerb appeal, especially if you are replacing a dated window style. The frames of your double glazing can even be spray painted a different colour to compliment your rendering or paintwork. Overall, high performing double glazing is a worthy investment for any home or business.

What to look for in a Double Glazing Installer

Double glazing is a highly competitive market, and as such there are several signs of quality to look out for.

Firstly, the company should be reputable and highly experienced in the measuring and fitting of double glazing. They should be able to provide information about the energy efficiency rating (known as a ‘U-Value’) that their windows offer.

Wherever possible, avoid companies that canvas at your door. Instead, find a double glazing installation expert who will advise you honestly about the work that needs doing and the costs involved. Also avoid any company that tries to pressure you into agreeing to the work.

Research the company thoroughly and check out their customer reviews before signing on the dotted line.

Different types of Windows

Not all windows are created equal! Double glazing can be offered in a variety of frame types. Depending on your budget, personal preference and property type, one material might be more suitable than the other.

  • Aluminium - Aluminium windows create a stunning focal point in your home. They have a minimal frame space which is sleek and modern. However, aluminium windows are expensive. They’ll also require painting or powder coating to avoid corrosion. Aluminium window frames can be used in a residential setting, but are mostly used in commercial buildings such as offices.
  • Fibreglass - Fibreglass windows are a rare type of window frame. Fibreglass has similar properties to aluminium but is stronger and more thermally efficient. As fibreglass windows are fairly new to the market, they are not as widely available compared with other frame types.
  • uPVC - uPVC stands for unplasticised polyvinyl chloride. It’s most commonly associated with double glazed windows, as well as door frames. The advantage of uPVC is that it’s more affordable than other window types. It can be easily moulded to create different shapes, making it an extremely popular material for window installers.
  • Wood - It’s also possible to have double glazing that sits within a wooden frame. Wooden windows are typically made from oak or timber. They can be used in most scenarios, but are most favoured in period properties. One downside is that wooden windows have to be regularly maintained to avoid the frame rotting. They are also prone to swelling and contracting according to the weather.

How to check a Double Glazing Installer’s credentials

As with any professional who carries out work out in people’s homes, they should be registered with a relevant trade body or association. Check if the company is registered with FENSA, who monitor building regulation compliance for windows and doors.

Can I get Double Glazing online?

It’s possible to find quotes for double glazing online. However, the installer will need to come to your home to properly scope the work.

What are signs that I need new Windows?

If it’s been some time since your windows were last installed, then they could be underperforming. Signs to look out for are a cold draught in the room, or misted units which are caused by a sealing failure. If your windows do not open or lock correctly, then they could be a security risk to your property.

Alternatively, if you simply dislike the look of your windows, then you should consider having them replaced. Modern looking windows can greatly enhance the look of your home.

Most windows have a 7-year guarantee. However, if it’s been longer than 20 years since your windows were installed they are most likely due a replacement. Another good way to tell is to get an energy efficiency report done for your home, which will tell you how much heat is being lost through your windows.

Commercial Double Glazing

Double glazing can be used in a commercial setting too. For example in offices, shops, restaurants or schools. Commercial double glazing must adhere to strict health and safety regulations, so can only be installed by a qualified provider. The company you choose for your commercial double glazing should have carried out many similar projects in the past, so that they can best advise you on these restrictions.

How much does Double Glazing cost?

The price of double glazing varies widely depending on how many windows need replacing, the window style, frame material, your location and of course the company you choose. As uPVC windows are custom made, the size of your windows will also affect the cost. It’s highly advisable to get several quotes before you make your final decision.

What do you love most about your job?

I really enjoy being trusted enough to be asked for advice or an opinion, and being honest enough to give a response, even if it may not be exactly what my customer might expect to hear. I have always taken a more technically-focused approach to sales, and have often managed to save customers significant amounts of money by tweaking a design here and there to come to a far more cost-effective solution; for example, reducing the size of a bifold door aperture on some planning/building regs drawings to enable fewer panels to be used, driving cost down as a consequence.

It's a great feeling to know that you have helped someone achieve the best possible results, for the best possible price.

What inspired you to start your own business?

Having worked for a fairly large company for a long time, there were a few things that struck me again and again, especially over the last 2-3 years, and it got to the point where I knew I could do a great job myself.

There always seemed to be a lack of understanding of the correlation between offering an exceptional after-sales service, and securing repeat business in future as a result.

Essentially, I grew tired of watching relationships that I had built with my customers during the sales process being tarnished by a lack of care and communication once the order had moved along the line and out of my hands, both in one-off retail cases and with regular trade customers whom I had dealt with over the course of years.

Why should our clients choose you?

I would like to think that my clients choose to work with me because they can be assured that they will get an honest, reliable service, for the right price. I have made it my business to know vast amounts about the products I sell and the industry I operate in (honestly, I am one of the biggest window and door geeks on the planet!), which inspires confidence from my clients that they are getting the best possible service from me.

New windows need to be carefully installed, ensuring that they are effectively sealed. It’s not advised to attempt to install new windows yourself as it can be a challenging and highly technical project. If you install a window incorrectly, it could negatively affect the performance of your windows, allowing moisture and draughts into your home. For this reason, it’s always best to hire a professional window installer to fit your new windows.

It generally takes around half an hour to remove an old window and fit a new one. This depends on the size and type of window. For larger or more complex windows, it could take up to an hour per window. Most houses will be able to have all windows replaced within a day, although for larger houses with more windows it could take up to two days.

If the window frames are in good condition, you may be able to replace the window without changing the frames. This sometimes works out as a more cost-effective way to replace or upgrade your windows. It’s worth consulting a professional window installer to find out if this is an option for your home.
