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.

Windows & Doors

Brilliant company from all we’ve dealt with, right through to the fitters, to the follow-up emails making sure everything was ok. Having used you before and after having work done to my property, I thought you the only obvious choice to return. Was a little worried as I’d had insulated render fitted and was concerned about the removal and refitting into the same size opening, and the damage it would cause. No worries, it seems. Each to their own trade as they say, and I’m glad they managed it and left me in no doubt, another great job done. Many thanks to you all. And see you in 15 years again?

Windows And Door

After a fair few months of looking for a good window provider we can say we are one hundred percent happy with Global. They exceeded our expectations from start to finish. Michael with the quote, the lovely ladies from the office and Andy and Josh who fitted our seven windows and front door. Very professional, good quality, quick and efficient work. A pleasure to work with such a team. Our next step is the conservatory with Global. Thank you and well done to all.

Excellent Service

My mum wanted to say thank you so much for the fantastic service Global windows have given her following her burglary. From start to finish they reassured her the replacement patio doors would be robust and fitted as quickly as possible to ensure the property was secured. On the day of fitting the fitters arrived promptly and installed the doors with no mess. The gentleman who organised this from Global (sorry she couldn’t remember his name) came out to check the doors and to see mum was happy with them brought her a beautiful bunch of flowers. Mum was over the moon. Thank you so much.

We decided to re-use this Company despite moving house and County. Global were helpful and very professional at all stages of the installation. We found all their staff friendly and knowledgeable. Dates given, returning phone calls etc. were all met. The price was very competitive, the quality of their products was excellent with a good range of colours and styles. The fitters were very hardworking, managed to get the work done in one day rather than the expected 2, mainly due to the fact they worked as a team, didn’t take breaks and clearly knew their job. Great company.
