How Much Do uPVC Sash Windows Cost to Install?

1500mm x 1500mm	£1,350-£1,400	£1,550-£1,600	£1,450-£1,500

The cost of an uPVC sash window will include the frame, a choice of glass, glazing bars and hardware, as well as the cost of labour to install the windows. Some providers will remove your old windows as part of the installation, but you should double-check before they start.

Most installers will provide high-quality uPVC sash window locks for security.

The cost of uPVC sash windows is directly proportional to the size of the windows you install. Larger windows are more expensive, but labour costs will rise if the installation requires two or more workers to complete.

Smaller windows may be less expensive, but unique sizes and forms might be costly to produce.

The amount you pay will be influenced by the number of uPVC windows you intend to install.

Obviously, the more windows you have to install, the more money you’ll spend on supplies and labour. If your quote does not cover the removal of all your old windows, you will need to budget for that as well.

You may require additional labour if you have a big number of windows fitted or if the uPVC sash windows are unusually huge or heavy, which will raise your overall expenditures.

The average cost of a craftsman installing uPVC windows is £150–£200 per day, so you’ll be spending roughly £600–£800 per day for labour if there are four fitters on-site.

The cost of uPVC sash windows and installation varies depending on where you live in the UK.

In terms of materials and labour, most people are aware that home remodelling costs are higher in London and the southeast of the country.

This is usually owing to greater business costs in the capital and its surroundings, such as insurance and premises rental.

The cost of installing uPVC sash windows is affected by the ease with which the windows may be accessed. The installation firm may impose additional fees if entry is difficult.

This is something you should talk about before starting the installation. Scaffolding may be required for windows above the ground floor, and this cost should be mentioned prior to installation day.

What are the uPVC Sash Window Supply Costs?

The cost of an uPVC sash window, without labour, is determined by the size, finish, type of glass, glazing bar, and hardware chosen. The table below shows the typical supply cost for various sized uPVC sash windows in various finishes.

Size	White	Coloured	Wood Grain Effect
600mm x 1000mm	£300-£350	£500-£545	£400-£450
900mm x 1000mm	£450-£500	£600-£675	£500-£600
1200mm x 1500mm	£475-£525	£615-£700	£550-£650
1500mm x 1500mm	£550-£675	£630-£750	£560-£675

If you’re planning to install your uPVC sash windows yourself, you’ll simply have to pay for the windows’ supply.

However, depending on the number and size of windows you purchase, you’ll need to consider how you’ll get them to the job site, whether you’ll be able to install them without a second pair of hands, and what you’ll do with the old windows after they’ve been removed.

While the supply prices will be lower than a supply and fit cost from an uPVC window provider, there are fees associated with DIY that would not be there if you hired a contractor to complete the job.

Delivery or van hire, scaffolding or scaffold tower hire, and disposal costs are all examples of these costs.

When determining whether to install the uPVC sash windows yourself or hire a window installation firm, all of these charges should be incorporated into your budget.

What are the Additional Costs of uPVC Sash Windows Installation?

Following your uPVC sash window installation, professional window installers will leave your property as neat and tidy as when they arrived.

Some less experienced installers, on the other hand, may accidently damage your walls when removing old windows, or you may do so yourself if you install your windows yourself.

You may need to replaster areas of the walls surrounding the windows in these cases. Plastering costs vary depending on where you reside, but the average is between £150 and £200.

Many individuals replace their windows as part of a home’s total remodelling. With this in mind, you may decide to complete other internal or external projects at the same time as you replace your windows.

The cost of hanging a door as part of an internal home renovation ranges from £70 to £140 for internal flush doors to £2,450 to £2,600 for a set of bi-fold doors.

The cost of the doors will be determined by the type of material used and the style chosen.

Internal doors made of hardwood are substantially more expensive than those made of softwood, while aluminium bifold doors are more expensive than those made of uPVC.

Sliding patio or French doors can cost anywhere from £400 to £1,500, depending on the style and size.

Tilt and turn features are available on some sliding patio doors, allowing for more ventilation without fully opening the doors. uPVC or aluminium are commonly used for these types of doors.

Replacing your windows may be part of a broader house makeover, which can cost anywhere from £100–£150 per square metre, depending on the nature and length of the repair work as well as the materials used.

Cost Affecting Factors

There are other expenses determining elements that might affect the price, aside from any additional work that you may have to do as a direct result of your uPVC sash window installation or works that you choose to conduct at the same time.

Size of Windows

The size of the uPVC sash windows you want to install will determine the price.

Larger windows not only need more resources to produce, but also demand more time and labour to install. Customized windows, such as those with an arched top or unique sizes, will cost more.

Minimum Fee

The majority of people will install or replace all of their windows at the same time. If your budget does not allow for this and you only want to do one portion of your home at a time, you may need to inquire about a minimum charge from uPVC window installation providers.

The price per window usually decreases as the number of windows installed increases.

Number of Windows

The cost is determined on the quantity of uPVC windows you have installed. The cost per window is often lower the more windows that are installed.

Keep in mind, however, that installing a larger number of windows may take longer and may necessitate additional labour.

Installation Location

For windows on the ground floor, there should be no additional fees, but for those on the first story, the installation business may need to hire scaffolding, which will increase the entire cost.

Timeframes

The amount of time it takes to install your uPVC windows will affect the amount of labour you pay and the cost of any scaffolding you hire. While the installer may have given you a timeline, unexpected complications can cause an installation to run late, so it’s a good idea to budget for delays.

Location of Property

The cost of your uPVC sash window installation is directly proportional to where you live in the United Kingdom.

The most costly areas in the UK are London and the southeast, however some other large cities may also require a larger budget.

When it comes to uPVC sash window prices, some parts of the UK may be less expensive. Installation and material prices are often lower in the north of England and parts of Wales.

Installation of UPVC Sash Windows by Tradesmen

We need to evaluate how much a professional will charge for installation to figure out how much installing uPVC sash windows will cost without the supply and material charges. The labour costs will be explained in this section.

A uPVC sash window installer’s average day rate is roughly £150–£200 per tradesperson. The price will vary depending on where you live in the United Kingdom.

For example, tradespeople’s prices in London and the surrounding area are always greater than in other parts of the country. This is owing to London’s high cost of living and higher business rates, which include insurance.

Labor expenses for uPVC sash window installation will vary depending on where you are in the country, but they will normally range from £125 to £150 per day per tradesperson.

You might spend between £250 and £450 per day for labour, depending on how many staff you have on-site.

These expenses do not include the cost of any materials used in the uPVC sash window installation or the cost of uPVC sash window prices; they only reflect the cost of labour.

How Long Do uPVC Sash Windows Take to Install?

The time it takes to install an uPVC window is determined by a number of factors, including the number of windows being installed, the number of tradesmen on site, ease of access, and any potential complications with the installation.

Taking Measures

The measuring of the window apertures is the first and most critical step in installing an uPVC sash window. Always take measurements from the outside and inside the window, as well as from two to three different locations on the window opening.

This assures that the windows will fit at the aperture’s narrowest point.

The window openings may not always be completely square, level, or plumb because sash windows are typically found on older, historic houses.

Before the new windows are installed, some apertures may be damaged and need to be repaired. All of these elements can have an impact on the size of the window apertures.

The method for taking measurements will be determined by how the original windows were installed. The measures on the inside may differ from the measurements on the outside as a result of this.

You’ll measure from brick to brick, either while only 20-40mm of the brick is visible or when the entire brick is visible. This is referred to as a check reveal.

This aspect of the installation will be handled by your installer prior to installation in order to determine the correct size of the uPVC sash windows to be installed. Before any other work is done, the measurements are normally confirmed against the windows on installation day.

Depending on the complexity of the project, measuring windows can take anywhere from one to two hours.

Removal of Existing Windows

The old windows must be removed on the day of installation. The length of time it takes will be determined by the size of the window and the amount of cleaning required of the aperture.

An existing sash window can usually be removed in under an hour.

If you’re replacing like-for-like uPVC sash windows, the job should go smoothly and fast, with minimal downtime. However, if there are any changes to the opportunities or other concerns that need to be addressed, the work may be delayed.

When replacing old or deteriorating windows, care must be taken to avoid damaging the window opening or adjacent surroundings during the removal process.

Installation

If all of the preparation work for the window installation has been accomplished, the installation should go smoothly.

The new uPVC sash window is installed and sealed around the edges to provide weathertight and draughtproof performance.

The installation may take an hour or two per window, depending on the size of the windows. It will also be determined by the number of individuals working on each window at the same time.

With good planning and a skilled crew, most installations of up to six windows may be completed in one day.

Scaffolding may be required if windows are to be installed on the first story of a property, and all necessary safety precautions are implemented. This could indicate that the job will take more than a day.

Benefits of uPVC Sash Windows

Installing new uPVC windows has both interior and external benefits for your home. Internally, uPVC double glazed windows will keep your home warmer, lowering your heating bills and carbon impact.

Before you decide to replace or install new windows, there are several factors to consider. Some of these will be determined by your budget, others by aesthetics, and others by local planning regulations.

However, there are numerous advantages to uPVC sash windows that should be examined prior to making a decision.

Low Maintenance

Low maintenance is one of the most practical advantages of uPVC sash windows in terms of keeping them looking beautiful and performing properly.

Unlike wooden sash windows, which need to be painted every few years, uPVC sash windows merely need to be cleaned with warm water and a little detergent.

Longevity

Sash windows made of uPVC have a 20-year or longer average lifespan, depending on the manufacturer and amount of maintenance.

Similar timber windows may survive as long if properly cared for, depending on the quality of the wood used in their manufacturing and the level of maintenance.

Choice of Finishes

Many uPVC sash window manufacturers provide a diverse range of colours and treatments. The colours range from plain white through grey, green, black, and wood tones like teak and oak.

The frames can also be finished with a smooth finish or a woodgrain look to simulate timber sash windows.

Property Style

The addition of uPVC sash windows will improve the appearance of your home from the outside. This is especially true for residences built in the time or to seem like Victorian or Georgian homes.

If you ever decide to put your house on the market, its curb appeal will help it sell faster.

Most property styles can be accommodated with uPVC sash windows, which come in a variety of frame finishes and colours. There are uPVC sash windows to compliment most homes, whether you want to keep a period property’s original charm or go for a more modern style.

Increased Thermal Efficiency

Single-glazed sash windows with timber frames were common in the past. The property’s thermal efficiency will be improved by replacing older windows with uPVC sash windows, which were notoriously draughty.

As a result, your heating expenditures will be lower and you will save money in the long run.

Better Security

Aside from providing a warmer environment, uPVC sash windows also give greater security. Sash windows used to have a bad reputation for being easy to open from the outside, but modern uPVC sash window locks are far more durable.

Affordability

uPVC windows are less expensive than wood or aluminum-framed windows. Although sash windows are often more expensive than casement windows, uPVC sash windows are less expensive than their wooden or aluminium counterparts.

How Much Does It Cost to Remove uPVC Sash Windows?

Although uPVC sash windows typically last between 15-20 years, you may need to replace one or more of them at some point. Not everyone will be able to achieve this on their own and will need to pay someone to help them.

If a window is damaged or the glass is cracked, it may not be possible to fix it, and the entire unit may need to be replaced. Depending on where you live in the UK, the average cost of removing an uPVC sash window is roughly £150–£200 per day.

The cost of disposal will vary depending on whether you remove the window yourself or hire someone to do so for you. Because most recycling centres do not accept uPVC windows, you may need to hire a specialised recycling firm to remove the old windows.

Because there are so many of them, it’s worth collecting quotes from a few to see if they’ll charge you or remove the old windows for free.

Q: Is it true that uPVC sash windows are more expensive than uPVC casement windows?
A: Sash windows are generally more expensive than casement windows due to their more sophisticated design.
