Here at TWS Leeds, we’re proud of our extensive industry knowledge and we make it our priority to help customers understand exactly what we offer. With this in mind, we’ve compiled a list of the most frequently asked questions we receive when it comes to replacing windows, so no matter what style of window or glazing you’re replacing we’re here to help you find the right solution for your home.

How do I know when I should replace my windows?

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. Mould in homes has been linked to health complications such as skin rashes, respiratory problems, and other allergic reactions, so it’s important to address the problem of moisture in your home before the problem escalates.

If you experience difficulty when opening or closing your windows. Windows that were not installed correctly can sometimes develop 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.

You hear a lot of outside noise. If your windows aren’t providing much protection from the sounds outside, they might not be sealed correctly.

You feel a draft when your windows are closed. There could be a number of issues here, including poor installation or faulty seals that are the cause.

What material should I choose for my new windows?

Here at TWS, we only supply uPVC windows. Since the 1980s uPVC windows have been the window of choice for most homeowners in Yorkshire. Easy to keep clean, fantastically reliable but surprisingly cost-effective, there’s plenty of reasons why homeowners love them.

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, such as sliding sash or casement, allowing you to create a unique look for your home without ever having to compromise on performance.

What type of windows do I have in my home?

If you’re thinking about replacing the windows in your home, one of the first things you’ll need to do is to identify what kind of windows are currently in your house.

Material: Identify the type of material used in the window frames it’s usually quite easy to identify the material used, simply by examining the interior and exterior of the frame and feeling the frame itself. If you are struggling to identify the material, you can try to locate the name of the manufacturer somewhere on your windows. A quick internet search of the manufacturer may help identify the material you have. If you are really unsure of the material you have, you could ask one of our experts when you enquire with us and we will do our best to help.

Glazing: The majority of homes in England today have double glazed windows. When looking at the glass, if you see two panes separated by a spacer bar then you have double glazing. Spacer bars are small pieces of plastic or metal that work to separate and support the two (or three) panes of glass in a multi-glazed window. If it’s just a single pane, you have single glazed windows. If there are three panes separated by two spacer bars, then you have triple-glazed windows.

Opening: Identifying how your windows open is another important point to recognise. The most common types of opening include side hung and top hung. The difference lies in where the hinges sit. Side hung windows open outward with hinges on the right and left of their frame. Top hung windows swing open using hinges at the top of the window frame. Simply opening your windows will help identify which mechanism they use. There are a few other types of window openings, so if you would like help identifying your type then please let us know when you enquire.

What is the difference between sliding sash windows and casement windows?

Casement windows usually open outwards from the building with side positioned hinges, like a door. This style is extremely popular in a lot of modern homes.

Sliding sash windows open by sliding horizontally up and down. Modern sliding sash windows work using a spring-loaded device called a spiral balance. Sash balances eliminate the need for weight pockets and can be installed in smaller openings and allow for larger window sizes and consequently a larger glass area. The style looks particularly fitting on older or period properties, as it reflects a style made popular in the Victorian and Georgian era.

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 security upgrades available allowing for the highest security standards possible, you can put your trust in us to keep your home safe and secure.

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 thing 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 meet or surpass the recommended energy efficiency level. Find out more here.

Can I get different coloured uPVC windows?
