Sash windows replacement prices

Sash windows are a beautiful and classic feature of many homes. However, over time, they may begin to show signs of wear and tear, and replacing them can be a vital decision. But let's explore the options available for sash window replacement and the associated costs.

New windows vs. window replacement

When it comes to replacing sash windows, there are two options available: new windows and window replacement. New windows require the existing frame to be removed and replaced, while window replacement involves installing new sashes within the existing frame.

While new windows may offer more confident benefits, such as excellent energy efficiency due to the new window frame and a wider range of design options, they can be more expensive due to the additional work required. 

Window replacement, however, can be a more cost-effective option, especially if the existing frames are in good condition.

Therefore, let's take a look at the cost point options below. These include the type of glass used, the size of the window, and the level of repair required.

Below is a table outlining the average cost of sash window replacement based on these factors:

New windows vs window replacement

Double Glazing£500 - £1,500
Whole Window Replacement£240 - £1,860
Repairs£200 - £500

It's important to note that these prices are only estimates and can vary depending on the factors mentioned above. Consulting with our professional sash window replacement network can provide more accurate cost estimates tailored to your specific needs.

Double glazed sash windows

Double glazed sash windows are a popular option for homeowners who want to improve the energy efficiency of their homes. They consist of two panes of glass with a layer of gas or air in between, providing better insulation and noise reduction.

 It reduces heat loss, making it the standard for new and replacement windows in the UK. This not only helps lower energy bills but also improves the home's overall comfort of your home. Double-glazed sash windows are also easy to maintain. They can add value to a property, making them a practical and stylish investment for any homeowner.

Double glazing vs triple glazing

Double glazing and triple glazing are two popular types of windows that offer improved energy efficiency and insulation compared to single glazed windows. While both options have their benefits, there are some key differences between the two that you should be aware of before making a decision.

The complex design of double and triple glazing, with their vertical sliding panels and intricate glazing bars, can make installing double or triple-glazed units more expensive than other types of windows. Additionally, strict planning regulations may require homeowners to opt for secondary glazing instead in conservation areas.

Glazing replacement is also an option for those looking to upgrade their existing sash windows. However, it's important to note that using thicker glass for improved energy efficiency can affect the window's appearance, particularly regarding sightlines and the size of the glazing bars. The process of glazing replacement can also be more complex for sash windows compared to other types of windows, requiring the services of a skilled and experienced professional.

Double Glazing:

  • It is made of two panes of glass that are separated by a space of air or gas.
  • Offers improved energy efficiency and insulation compared to single glazed windows.
  • Can reduce outside noise levels.
  • Generally, more affordable than triple glazing.

Triple Glazing:

  • It consists of three panes of glass separated by two gaps of air or gas.
  • It provides even better energy efficiency and insulation than double glazing.
  • Offers additional benefits such as increased security and reduced condensation.
  • It can be more expensive than double glazing.

Benefits of double glazing

Double glazed windows offer improved energy efficiency by providing insulation against heat loss in winter and heat gain in summer. They also reduce outside noise levels, making homes quieter. Double glazing is an affordable option compared to triple glazing and is a popular choice for homeowners seeking energy efficiency improvements.

Benefits of triple glazing

Triple glazing offers maximum energy efficiency and insulation, making it ideal for homes in colder climates. Additionally, the extra layer of glass provides increased security, making them more difficult to break. Triple glazing also reduces condensation on the inside of the windows, keeping homes drier and more comfortable.

Which is right for you?

Ultimately, the decision between double glazing and triple glazing comes down to your specific needs and budget. Double glazing is a great option for those looking to improve their home's energy efficiency and reduce outside noise levels without spending much money. In contrast, triple glazing is best for those in colder climates who are looking for maximum energy efficiency and insulation. 

Consider your climate, budget, and long-term goals for your home when making your decision.
