So, you are wanting to upgrade all the windows and doors in your home. You have received quotations from different companies that seem to compare well. But how do you know which one you can trust to do the job right? Whilst it may be tempting to jump at the cheapest quote, it is important that you do your research before making your decision. Here are the right questions to ask to ensure you are choosing the best double-glazing installer for your home improvement project.

Is the double-glazing installer accredited?

One of the first things you want to check before accepting a quote is whether the company is accredited. As the consumer, having a third-party body to fall back on gives an extra piece of mind, and further cements your faith in the company, as you know their work meets the industry standard. Check with the company what valid accreditation(s) they have, as this will tell you a lot about their practises.

Here at Emerald, we are accredited by FENSA, a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. It was put in place to ensure that work carried about by installers across the UK complies with building regulations, is registered with the local council, is energy efficient, and meets minimum standards of quality. FENSA also offer insurance-backed warranties. You may have also heard of CERTASS, which is a similar accreditation to FENSA.

As well as FENSA, Emerald are also members of the CPA (Consumer Protection Association), which offer insurance back guarantees and deposit protection to consumers. It also offers access to support from a dedicated advice team, should a problem arise during or after the installation. The CPA regularly review work carried out by their members, ensuring it displays best trading practise standards.

Emerald are also members of the GGF (Glass and Glazing Federation), which represent the companies that manufacture, supply or install glass and glazing products in the UK and internationally. The GGF guides and protects homeowners when buying glass or glazing products and services.

Does the double-glazing installer have good online reviews?

Parting with a large sum of money can be daunting, especially if you are not familiar with the company. Because of this, it is imperative that you take the time to research into the companies’ online reviews, to see how previous customers have rated their experiences. Reliable reviews can be found on sites independent from the company, for example Google or Yell.

At Emerald, we pride ourselves on our online reviews, with over 120 5-star reviews on Google, and over 420 4 and 5-star reviews on Yell.

How long have the double-glazing installer been trading?

For obvious reasons, a company that has been trading for many years is more favourable than one only just starting. Other background information is important too, such as whether the company employs their own installers.

Emerald Windows and Doors have been trading for over 10 years, and is family owned and run. As such, we believe a personal and friendly approach is the way to go!

Does the installer have a showroom/office you can visit?

Having the option to see and feel the products up-close before making your decision is a huge benefit. It gives you confidence in the quality, and a better idea of how the products will suit your home. As well as this, it can be reassuring to know there is a dedicated team that you can visit or call should you have any queries, at any stage of the process.

Both the Emerald head office and showroom are in Swindon, Wiltshire. The Emerald House is in a residential area, as opposed to an industrial estate, so is very welcoming and relaxed. We invite our customers to visit us as many times as they like. Whether it be to compare products in the showroom or to make a payment, our friendly team is always on hand to help.

The Emerald showroom features a range of products, from aluminium bifold doors to timber windows, and includes samples from industry leading brands such as Solidor and the Residence Collection. Book an appointment to visit our Swindon showroom today!

Does the double-glazing installer guarantee their products and service?

No matter how perfect the installation of your windows and doors seems, it is crucial that the products and service come with a guarantee. This means that, should you have any problems down the line, it will be covered and dealt with by the original company.

At Emerald, our windows and doors come with a 10-year guarantee.
