When it’s time to replace your windows and doors or you’re planning to install a conservatory or orangery; extensive research is paramount. To ensure that your installation is a complete success it’s important to employ a professional and reputable company. Firstly, choosing a company who manufacture and install will help to maintain product quality. Secondly, look for positive customer reviews and testimonials for independent recommendations which vouch for a company’s integrity.

To help you on the road to a successful double glazing installation, here are 10 fundamental questions to ask your manufacturer and installer. Any reputable company will be happy to answer all your questions.

1. How much will it all cost?

All manufacturers and installers should provide comprehensive, no obligation quotes before any contract is signed.

2. How long will it take?

A time schedule helps you to organise your life around the installation and ensures you have a realistic idea when the work will be completed.

3. Do you provide a guarantee?

A product and installation guarantee gives you peace of mind that your investment is protected against any unforeseen problems.

4. What accreditations do you have?

Third party accreditations from industry bodies such as FENSA set industry standards and promote professionalism.

5. Can I view the products prior to installation?

A showroom is a great place to try out a company’s products and speak to the team in person.

6. What energy efficiency ratings do your products achieve?

An important consideration in the 21st century and a vital factor when selling your home.

7. What product options are available?

Choice is an attractive attribute. Options in terms of style, colour, hardware, and security are all factors to consider.

8. Is a finance package available?

Planning your budget in advance will help you to feel comfortable in your investment.

9. What level of security is provided?

Secure locking systems protect your home and can help to reduce insurance premiums.

10. What glazing options are available?

Whether your priority is security, thermal efficiency, privacy, or individuality; your choice of glazing can transform the look and performance of your home.

New Window and Window Swap

Had Global swap an existing window for a new bi-fold door and install a completely new window in our dining room. As hoped, both have created a lot of addition light. I have used Global in the past and would use again in the future. Professional service provided from the office staff. They were the only business I spoke to that was aware of the new building control regulations that were introduced at the start of October last year and therefore acted as Principal Designer keeping the works compliant. The guys that completed the work were very respectful, polite and tidied up after themselves. Would recommend.
