How do I know when I should replace my windows?

1. If you’ve noticed condensation build-up in-between the double glazed panes of glass it could mean that your window seals have failed, allowing moisture into your home. Once a seal fails, any insulating gas used to make the window energy efficient is now gone. This means that your double glazing is now inefficient, and your energy bills may start to creep up.

2. If you experience difficulty when opening or closing your windows it could indicate that they were not installed correctly which can sometimes cause balance issues, making them challenging to operate. Windows that are rusting or rotting can also be difficult to use. If you can’t close your windows properly, you may not be able to lock them, which can impact the safety of your home.

3. If you hear a lot of outside noise, it means your windows aren’t providing much protection from the sounds outside. This could be because they might not be sealed correctly.

4. If you feel a draft when your windows are closed this could be caused by a number of issues, including poor installation or faulty seals.

What material should I choose for my new windows?

Here at Global, we offer a huge range of uPVC windows. As the most popular window material, uPVC is well known for its remarkable reliability, hardwearing finish, and for how easy it is to keep clean. It’s also a more budget-friendly option than other window materials. We offer an eclectic mix of uPVC window styles allowing you to create a unique look for your home, regardless of what type of home you have.

Do I need planning permission to replace my windows?

No. You do not need planning permission to replace existing windows or doors, though you will need to check to see if you are located in a conservation area as you may be restricted with what designs or materials you are allowed to use. You can check this with your local council. If you are building an extension, you will need planning permission.

How secure are your windows?

We pride ourselves on offering the utmost security for your home, giving you total peace of mind. With a plethora of security upgrades available allowing for the highest security standards possible, you can put your trust in us to keep your home safe and secure. Get in touch if you want to know more about our window security options.

How does double glazing work?

Double glazed windows are constructed by placing two panes of glass closely together, as opposed to just a single pane of glass. One pane of glass is on the exterior, and one sits securely inside. Between the panes, there is a thin gap that is often filled with argon gas. Argon gas is used to slow the transfer of heat through windows. Since it is so vicious, it acts as a fantastic thermal barrier. Since molecular movement is so restricted within argon gas, far less heat is transferred and far less heat loss occurs. This helps to really improve the energy efficiency of homes.

How much does double glazing cost?

Our windows are bespoke, just like our quotes. In order to give you an accurate quotation, we ask that you get in touch with us directly, so we can tailor a price specifically to your individual requirements. As always, there is no obligation.

What do window energy ratings mean?

Window energy efficiency rating schemes are based on a scale that ranges from A-G. This system is similar to the labeling system used that you may have seen on fridges, washing machines, and cookers. An ‘A’ rating indicates a good level of energy efficiency, whilst G is the lowest rating. Low-rated windows will not normally satisfy building regulations requirements. We’re confident that all of our windows, regardless of material or style, meet or surpass the recommended energy efficiency level. Find out more here.

Can I get different coloured uPVC windows?

We can install uPVC windows in a variety of RAL colours, from contemporary Anthracite Grey to a more classic White. Please contact us to discuss the colour options available and to request a colour swatch. We also offer versatile dual colour uPVC windows. This means that the colour of the interior of your window can be different from the exterior. This is beneficial to homeowners looking to match new windows and doors with their existing décor.

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?

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.
