uPVC, Aluminium and Timber

Aluminium, uPVC and timber windows offer many choices of frame styles and colours, so feel free to tear up the rule book and be different.

We supply a wide range of double-glazed windows, including uPVC and aluminium. Your choice of material is usually led by how you want your home to look. If you live on a road of similar houses, you may prefer to look similar to the other houses or stand out as being different. You don’t have to choose the same as you had before. We’ll help you to envision any changes. You may want a completely different configuration to improve airflow. We design for many older-style houses that suit sash windows, while owners of more modern homes usually choose casement windows. Both aluminium and uPVC windows offer many choices of frame styles and colours, so feel free to tear up the rule book and be different. If you want the traditional look of wood, maybe our flush casement windows will suit you. Explore some of our recent window and door installations in South Wales.

Pricing Policy

It can be a problem for genuine businesses to compete with companies who double their prices to advertise 50% discounts. When we don’t offer these discounts, customers can think it means that we are expensive. This is a misconception born out of the discount culture that is prevalent in the home improvement industry. What do you want? A price that starts at £10,000 and is reduced to £5,000 after a couple of hours of haggling or someone who carries a genuine price list and tells you straight away that the price is £5,000?

When you visit our showroom, or we visit you, we will measure, advise and either give you a quote there and then or send it to you. It will be the best price we can give. You won’t have to haggle or wonder whether you should have pushed for more. If you read through our feedback on Google, you will see that this approach is mentioned in the comments.

Quality Control

Fully employed installers mean that we can control the quality. The double-glazing business is inconsistent throughout the year so most companies use self-employed contractors so that they don’t have salary overheads during quiet times. This can lead to unreliable standards. This isn’t good enough for us. We want to control the standards on every installation. For this reason, we fully employ our installers. This also means that our installers can take time out for training because they don’t lose income while they do so. 

Peace of Mind

We’re also Certass approved, and we secure your deposits with QANW Insurance Backed Guaranteed for further peace of mind. Exceptional installers fit our doors and windows with a great deal of expertise backed by continuous training. This is one of the benefits of using a company that fully employs its installers. We insist that they take the time to complete a first-class job, and because they are employed, they can afford to do so. We are Allchecked approved installers with verified reviews and verified by Which Trusted Traders.

Frequently asked questions about double glazing

What is Double Glazing?

Double glazing is a type of window or door that is specially designed to insulate a building from both heat loss and noise pollution. Double glazing is made up of two panes of glass with a gap between them which is filled with insulating gas, and then sealed with a spacer bar around the edge.

This gas acts as a buffer against heat transfer, preventing heat from escaping during the winter while also blocking heat from entering during the summer. This makes double glazing an effective way to regulate the temperature in a home or building and can lead to a reduction in energy bills. Additionally, the two panes of glass provide an extra layer of sound insulation, making double glazing ideal for those who live on busy roads or in noisy areas.

Find out more about double glazing.

Is it worth replacing old double glazing?

Yes, it is generally worth replacing old double glazing. Old double glazing can have a number of issues, such as leaks, condensation, and reduced energy efficiency, which can result in higher energy bills. Additionally, newer double glazing technologies have improved significantly in recent years, which means that the replacement windows will likely be more energy-efficient and better at insulating your home. This can help you save money on energy bills in the long term, as well as make your home more comfortable to live in.

Savings will depend on the standard of your current glazing. The largest savings come from replacing old single glazing with good qulaity double glazing.

What is the life expectancy of double glazing?

The life expectancy of double glazing can vary depending on the quality of the installation and the materials used. In general, double glazing can last for around 20 years or more if it’s well-maintained and installed correctly.

Factors like exposure to harsh weather conditions, damage, and wear and tear can impact its lifespan. It’s important to properly maintain your double glazing and to have it checked regularly by a professional to ensure its longevity.

It’s not usually the double-glazing units that end the life of windows although they can fail if air gets into them. The frames can warm especially if they are cheap or very old. Mostly windows are changed because the owner wants a fresh new look or a different style.

Is double glazing better now than 20 years ago?

Yes, double glazing technology has advanced significantly in recent years, making it more energy-efficient and durable than it was 20 years ago.

Modern double glazing windows feature better-made frames, stronger and more impact-resistant glass, improved sealants, and better insulation. These advancements in technology contribute to better noise reduction, reduced heat loss, and increased security.

Modern double glazing now offers a variety of customisation options such as decorative finishes and color variations. In summary, double glazing today is far superior to what it was 20 years ago.

How do I know if my double glazing needs replacing?

There are several signs that your double glazing may need replacing. Here are a few things to look out for:

  1. Condensation between the glass: If you notice condensation between the panes of your double glazing, it could be a sign that the seal has been compromised and moisture has seeped in. This can reduce the insulating properties of your windows.
  2. Drafts: If you feel a draft coming from your windows even when they are closed, it could be a sign that the seals around the window frames have deteriorated.
  3. Difficulty opening and closing: If you have to struggle to open or close your windows, it could be a sign that the frames have warped over time.
  4. Damage: If your double glazing has any visible damage such as cracks or chips, it may need to be replaced.

If you notice any of these signs, it may be worth getting your double glazing inspected by a professional to determine whether replacement is necessary.

Our quotes are free and without obligation so don’tbe concerned about calling us out to advise.

What is the best time of year to buy double glazing?

While there isn’t necessarily a specific “best time” to buy double glazing, there are a few factors to consider depending on who you buy from.

Firstly, many companies tend to have (so-called) sales or promotions during the slower months of the year when there isn’t as much demand. This can include the winter months, as people are less likely to be thinking about home improvements during this time. Thes discounts are available all year but disguised as different offers so in reality, there is no difference.

You’ll find that we do not play games with prices. Our prices are fair and real. We do not inflate prices to give false discounts. 

If you  have your double glazing installed during the summer, it can help to reduce the disruption to your daily routine. You may also benefit from improved energy efficiency during the warmer months, as double glazing can help to keep your home cooler by reducing heat gain through your windows.

Ultimately, the best time to buy double glazing will depend on your individual circumstances and priorities.
