What Affects the Cost of Installing a Wooden Sash Window?

Installing a wooden sash window can be a great way to add value and style to your home. But, before you start the process of installation, it’s important to understand the factors that will affect the cost. In this guide, we’ll cover everything you need to know about what affects the cost of installing a wooden sash window so that you can make an informed decision when planning your project. We’ll discuss topics such as materials, labour costs, installation techniques and more. So let’s get started!

Types of Wooden Sash Windows

When it comes to wooden sash windows, there are a few different types available. The type of window you choose will affect the cost of installation.

The most common type is the traditional sliding sash window. This style has two sashes that slide up and down on vertical tracks, allowing you to open and close them easily. These windows are usually made from timber such as pine or oak and can be stained or painted to match your home’s decor.

Another option is the casement window. This type of window opens outward like a door, with hinges on one side and a handle on the other. Casement windows are usually made from hardwood such as mahogany or teak and offer more security than sliding sash windows. Finally, there are bay windows which consist of three separate frames connected together in an arc shape.

These types of windows can provide additional light into your home and also create an interesting feature in any room they’re installed in. Bay windows are typically more expensive than other types due to their size and complexity of installation.

Measurement and Fitting Costs

When it comes to installing a wooden sash window, the cost of measurement and fitting is an important factor. The size and shape of the window, as well as any additional features you may want, will all affect the price.

Measurement costs depend on how complex your window is. If you’re replacing an existing window with a new one of the same size and shape, then the measurement process should be relatively straightforward. However, if you’re looking for something more customised or unusual, then it can take longer to measure accurately and this will add to the overall cost.

Fitting costs are also dependent on complexity – for example, if there are multiple windows that need to fit together perfectly or if there are tricky angles or shapes involved in the design. It’s worth getting several quotes from different installers so that you can compare prices and make sure you get value for money.

It’s also important to bear in mind that installation costs can vary depending on where you live – for example, some areas may have higher labour rates than others which could impact your final bill.

Materials Used for Installation

When it comes to installing a wooden sash window, the materials used for installation can have a big impact on the overall cost. Depending on the type of window you’re looking to install, you may need different materials and tools.

The most common material used for installing a wooden sash window is wood. You’ll need to make sure that you get high-quality wood that is treated and sealed against moisture and rot. If your window is made from softwood, such as pine or spruce, then it will require additional treatment to ensure its longevity. Hardwoods are more expensive but they are also more durable and require less maintenance over time.

In addition to wood, you may also need other materials such as nails, screws, sealants, weatherstripping, putty or glazing compound, paint or stain for finishing touches, and hardware like locks or handles. All of these materials should be chosen carefully in order to ensure that your window lasts for years without any problems.

Labour Costs

Labour costs can have a big impact on the overall cost. The amount of time and effort required to install a wooden sash window will vary depending on the size and complexity of the job. Generally speaking, larger windows with more intricate designs will take longer to install than smaller, simpler windows. In addition, if you’re hiring an experienced professional to do the installation, their hourly rate may also affect the cost.

So make sure you factor in both the size and complexity of your window as well as any additional labor costs when estimating how much it will cost to install your wooden sash window.

Removal of Existing Window

Removing an existing window is one of the first steps in installing a wooden sash window. Depending on how easy it is to remove the old window, this could be relatively straightforward or quite complicated.

If you’re replacing an existing wooden sash window, then the process should be fairly simple as you can just unscrew and take out the old frame. However, if you’re replacing a more modern PVCu or aluminium framed window, then there are likely to be additional complications. You may need specialist tools and skills to get these windows out safely without damaging your property. This can add time and cost to the installation process.

If you have an older building with solid brick walls then it might be necessary to use a hammer drill or similar equipment to make space for the new frame. Again, this will add time and cost to your installation so it’s worth factoring this into your budget when planning your project.

Disposal Fees for Old Window

Disposal fees for an old window can be a significant factor when it comes to the cost of installing a new wooden sash window. Depending on where you live, there may be local laws or regulations that require you to pay a fee for disposing of your old window. This is usually done by hiring a professional service to remove and dispose of the window safely. The fee can vary depending on the size and weight of the window, as well as any hazardous materials associated with it. It’s important to check with your local government before beginning any project so you know what fees you may need to pay in order to comply with local laws.

Additional Expenses for Building Permits and Insurance Coverage

When installing a wooden sash window, you may need to factor in additional expenses for building permits and insurance coverage. Depending on the type of window you’re installing, the cost of these permits can vary greatly.

If you’re replacing an existing window with a new one, you will likely need to get a building permit from your local municipality. The cost of this permit depends on the size and type of window being installed as well as the location and age of your home. Generally speaking, it is best to contact your local municipality directly for more information about the specific requirements and costs associated with obtaining a building permit.

You may also want to consider getting insurance coverage for your new windows in case any damage or accidents occur during installation or afterwards. Homeowners insurance typically covers some types of damage caused by storms or other natural disasters, but it doesn’t cover everything so it’s important to make sure that your policy covers any potential risks associated with installing new windows. Additionally, if you are hiring someone else to install the windows, make sure they have their own liability insurance as well in case something goes wrong during installation.

Finishing Touches and Accessories

Finishing touches and accessories can make a difference. From adding a decorative touch to providing extra insulation, these additions can add to the overall cost of installation.

For starters, you may want to consider adding some decorative trim or moulding around the window frame. This will give your window an attractive look that adds character and value to your home. You may also want to choose different types of hardware for your window, such as brass handles or locks for added security.

Another important factor is energy efficiency. If you’re looking for ways to save on energy costs in the long run, you should consider investing in double glazing or triple glazing for your windows. This will help keep heat inside during winter months and cool air inside during summer months, which can result in significant savings on energy bills over time.

Finally, if you’re looking for even more insulation from noise pollution or extreme temperatures outside, then weatherstripping is a great option. Weatherstripping helps seal gaps between the window frame and wall that could let air escape through them otherwise – making sure that your home stays comfortable all year round!

Choosing the Right Installer or Contractor

Choosing the right installer or contractor for your wooden sash window installation is an important decision. It’s important to make sure you find someone who is experienced and qualified in this type of work, as it can be a complex process.

Start by asking friends and family for recommendations, or search online for reviews of local contractors. Make sure that any potential contractors have experience with wooden sash windows specifically, as this type of installation requires specific skills and knowledge. Ask them about their qualifications and experience, as well as the types of materials they use for installations.

When you’ve narrowed down your list of potential installers, get quotes from each one so you can compare prices. Make sure to ask about any additional costs that may not be included in the initial quote, such as disposal fees or other services like painting or staining the wood. Also ask if they offer warranties on their workmanship – this will give you peace of mind knowing that any problems are covered should something go wrong during the installation process.

Maintenance and Repair Costs Over Time

As with any window, regular upkeep is essential in order to keep your window looking its best and functioning properly. This includes things like cleaning and lubricating the moving parts, checking for rot or damage, repainting or staining if necessary, and replacing broken glass. All of these tasks can add up over time, so it’s important to factor in the cost of maintenance when you’re considering installing a wooden sash window.

Benefits of Installing a Wooden Sash Window

Installing a wooden sash window can provide many benefits to your home. For starters, they are an attractive and timeless addition to any home. Wooden sash windows are known for their classic design and aesthetic appeal, making them a popular choice for homeowners looking to add character and charm to their homes. Not only do these windows look great, but they also offer superior insulation compared to other types of windows. This means that you’ll be able to keep your energy bills lower by preventing heat loss in the winter months. Additionally, wooden sash windows are incredibly durable and require minimal maintenance over time – making them a great long-term investment!


In conclusion, the cost of installing a wooden sash window depends on several factors. The size and type of window, the quality of materials used, and the complexity of installation all affect the final cost. If you are considering installing a wooden sash window, it is important to take these factors into account when budgeting for your project. Additionally, if you are hiring a professional installer, make sure to get multiple quotes from different companies to ensure that you get the best deal possible.
