Double glazing is one of the popular home improvement projects currently. It provides many perks, including better insulation. But you have to ensure your double glazing is installed correctly to reap those benefits, so you should be keen when choosing your installer. After all, you don’t want to end up with shoddily fitted windows or doors that offer little benefit.

Here are the evaluations for finding a reputable double glazing specialist.


Experienced double glazing specialists have been in the industry for many years, so you can be assured they provide quality services. One of the ways to gauge the experience of a double glazing installer is to look at their number of years in the industry. The more they have been practicing, the more experienced they are. A double glazing provider that has been in the industry for a long time has also built a good reputation which improves its credibility.

Check out previous work.

The previous work the company has accomplished speaks more about it when it comes to home improvement services. Therefore enquire about the previous double glazing projects the specialist has completed. You can rely on photos or request permission to visit and see the work physically, which can help you make an informed choice.

Look at customer feedback.

While every double glazing specialist will tell you how much an expert they are, it is best to hear from the customers themselves. Look at the reviews of customers who have tried and tested the company’s services. It is a great way to find out about the quality of their services and the customer experience to expect. You can look at reviews on the company’s website, social media comment sections, or other reviews platforms.

FENSA accreditation

It is best to look for a double glazing company registered with a competent person scheme such as FENSA, BM Trada, and Certass as a guarantee that they comply with the required building regulations. Such companies are insurance-backed, which means that they give an insurance-backed guarantee on their installations.

It also means that the company adheres to specific standards and competencies for double glazing services. Such compliance can also save you the cost and time of registering your window and door installations with local authorities.

Find out about payment and insurance.

What happens if accidental damage occurs on your property? That is why you should enquire about liability insurance before the work begins. It is advisable to work with a double glazing company with adequate liability insurance to be satisfied that you are not liable for any damages on your property during the installations. You should also ask for a breakdown of the costs in writing to avoid surprises regarding payments.

Compare different providers

You don’t have to engage the first double glazing specialist you encounter, no matter how experienced they seem. You should compare different quotes to ensure you choose the best provider.


Do not rush to make the decision- you should take all the time you need to ensure you get a reliable and trustworthy double glazing specialist.
