Double-glazed windows offer a host of benefits. They can save money on your utilities, increase the value of your property, and even reduce the noise that filters in through the window.

However, since switching to double-glazed doors and windows is a significant investment, you’ll need to ensure that your choice of window and door replacement company is reliable; but how do you choose with so many options?

In this blog post, we’ll discuss everything you need to know to find the best Perth Double Glazing window installation company.

What Are Double-glazed Windows?

Before discussing how to find the best double-glazing company, it may be helpful first to understand what double-glazed doors and windows are.

Double-glazed windows are systems designed to improve the energy efficiency and insulation of your household windows, according to the Australian Window Association.

Single-glazed Versus Double-glazed Windows and Doors

Unlike single-glazed windows and doors that are made using a single sheet of glass, double-glazing uses two glass panes to improve the strength and insulation properties of the windows.

Typically, a layer of dehydrated air or inert gas is placed in the air gap between the sheets of glass to achieve this.

Why Install Double-glazing?

Because up to 40 per cent of heat loss occurs at your windows, double-glazing can help to stop hot air from moving in or out through the glass. This means that your home will be warm during cold months and cool during hot summers.

The Importance of Choosing a Reputable Service Provider

However, because improper installation can lead to moisture build-up in the system, it is important to hire a reputable company that knows exactly what they’re doing. After all, double-glazed windows cannot be repaired, so shoddy workmanship could leave a huge dent in your pocket.

Moreover, your windows and doors protect you from the elements and intruders, so ensuring that you choose products that meet safety standards is essential.

What to Look for in a Window and Door Replacement Company

When it comes to choosing a service provider for your window installation, what do you look for? In the section below, we’ll discuss some of the most important qualities that your service provider should have.


As Seen on the Block 2022

Experience is an essential quality for a service provider to have. The ideal double-glazing provider will have been in operation for a respectable number of years.

This indicates that the business has a high level of double-glazing experience and skill. A company with a long history in the industry is likely to have also developed a strong reputation.

Quality Products

The truth is that your doors and windows play an important role in ensuring the safety of your family, which is why it is essential to choose a provider that offers reliable products. Whether you choose uPVC windows or aluminium windows, you must ensure that they meet safety standards.


Another excellent quality for a uPVC double-glazing company to have is assurance in their quality of work. You can tell that a provider believes that the products they promote and the service they provide are high-quality when the company offers a guarantee.

Customer Reviews

Installing window frames and double-glazing can go horribly wrong without the proper training and expertise, so you must check that the company you’re working with doesn’t just make empty promises but actually delivers the goods.

You can do this by reading online customer reviews to learn more about the experiences homeowners like you had when using this provider.

Look for a Double-glazing Provider That’s Locally Owned and Run

It’s great to support local businesses, and when you choose a local company, you have the assurance that you’re dealing with a team that understands what its customers want.
