Are you getting tired of your windows? Or are they broken beyond repair? Then it may be time to replace your windows!

Not only does it add value to your home, but it also improves energy efficiency and reduces energy bills.

But before you do anything, it’s important to know how much all this will cost.

Cost of Window Replacement and Repairs in Brisbane

In Brisbane, the average window replacement cost is $50 per hour if you’re hiring a professional. If you’re replacing the windows yourself, you can expect to spend between $300 to as much as $1,200 on window materials.

These estimated average costs can vary depending on the type of materials used and the window size.

Cost of Different Types of Windows

One of the important factors that can change the cost of window repair or replacement is the type of window. Bigger windows with more glass let in more light, but they’re more expensive. If you’re on a limited budget, choose smaller or more traditional options.

We’ve rounded up the prices of some of the most common windows and the average cost of replacing them.

Type of Window	Average Replacement Costs
Single-hung windows	$50 – $100
Double-hung windows	$350 – $400
Fixed pane windows	$50 – $100
Bay windows	$500 – $1,000
Bi-fold windows	$1,250 (per square meter)

Different types of windows come with a variety of benefits and drawbacks. When choosing one, a number of things need to be considered such as its shape, the amount of ventilation it offers, and its cost. The different window types are listed below.

1. Picture Windows

As their name suggests, picture windows offer a view of the outside. If needed, they come in quite big sizes. It may or may not have metal grids that slightly restrict the view but can somewhat lessen the risk of shattering (particularly for large glass).

Typically, picture windows are fixed, which means they cannot be opened. A fixed picture window won’t naturally allow for ventilation, but its permanent seals offer the added advantage of increasing energy efficiency.

The total cost of installing picture windows depends on the type of material and its size. Picture windows made of vinyl and fiberglass are more affordable compared to wooden ones which can be more pricey.

On the other hand, the task of replacing a picture window is a little bit technical. Thus, it requires a professional window installer.

2. Casement Windows

Typically, casement windows include a hand crank at the bottom that must be twisted in order for them to swing open. Casement windows can offer excellent ventilation since the entire window opens, unlike many sliding window designs.

They can be installed in high or difficult-to-reach places because the crank is easy to use with one hand at arm’s length. They are also slightly more energy-efficient than sliding windows as they are gasketed around the sides of the swinging window panel. 

High-quality casement windows may not have an issue for their entire lifespan, but their crank mechanism may ultimately wear down and need repairs. Moreover, cleaning the exterior of casement windows from inside the house can be challenging or impossible.

3. Horizontal Sliding Windows

Due to their versatility and reasonable cost, horizontal sliding windows are probably more common than any other style. When compared to single or double-hung windows that open vertically, horizontal sliding windows are usually wider.

This type of window is available in single-slider and double-slider varieties. A horizontal sliding window’s exterior is typically easy to clean from inside the house, unlike some casement or awning windows. 

On the other hand, horizontal sliding windows are considered to be a little less energy-efficient than hinged windows. Occasionally, they can also accumulate dirt or grime in their sliding channel.

4. Single Hung Windows

Single hung windows, which are typically vertical sliders, are commonly installed in smaller rooms like restrooms or bedrooms. They only have the bottom sash that can be opened, as opposed to double hung windows where both windows can be opened.

Single hung windows bring a lot of benefits. This style of window offers access for cleaning, optimum ventilation, and is simpler to replace than other window designs.

On average, single hung windows are around 10% to 20% less expensive than double-hung windows. While this cost difference may seem negligible if you have one or two windows to replace, the cost can add up if you have a total window replacement.

5. Double Hung Windows

When closed, double hung windows resemble single hung windows in appearance. “Double” hung refers to the ability to open both sashes. With this, a double hung window can offer better ventilation than a single hung window of the same size.

There are sliding versions of double hung windows as well. However, both sashes on a sliding model cannot be opened at the same time.

Double hung windows can be safer than single hung windows, especially for homeowners with small children or dogs. This is due to its mechanism which allows you to open the top window while the bottom stays locked.

6. Bay Windows

Bay windows are made up of multiple angled window panels that permanently protrude outward beyond home walls. Bay windows, which are typically seen in kitchens, can offer expansive peripheral views that flat windows cannot.

The middle window in a conventional bay window configuration is a fixed picture window. On the other side, the two flanking windows may be casement, single- or double-hung windows that can be opened, providing enough ventilation.

Bay windows are typically tucked beneath an eave. However, if there are no eaves or if you install it in the middle of the wall, you will need to build a small roof above it.

Moreover, bay windows also require structural support from below using braces or above using support cables. All of these additional requirements to install this type of window will add up to the overall cost.

7. Awning Windows

Basically, awning windows are casement windows with a vertical swing-open design. Similar to casement windows, awning windows frequently offer good ventilation and a tight seal.

In bedrooms, awning windows are common. Due to the relatively simple operation of the crank mechanism, they can be mounted in high or small spaces such as above doors or other windows.

Compared to other window types such as casement and sliding windows, awning windows are generally cheaper. This is due to the fact that they are typically smaller than most windows.

The simplicity of the design of this window type also means that they are affordable to purchase and install. If ever they got broken, fewer parts may need replacement.

Cost of Window Frame Materials

It’s a good idea to understand the advantages and disadvantages of the different window frame types available on the market. Read on to find out everything you need to know about various window frame materials before you replace your windows.

The type of window frame material can also influence the overall window replacement cost. 

Window Frame Material	Average Replacement Costs
Vinyl	$350 – $750
Wood	$800 – $2,000
Fiberglass	$600 – $900
Aluminium	$150 – $400
Composite	$250 – $1,100

1. Aluminum

Aluminum window frames are a good option for homes with larger windows as they are versatile and provide strong support for heavy sheets of glass. One of its advantages is its affordability compared to other material types.

However, aluminum is one of the least desirable solutions for energy efficiency. This is due to the fact that aluminum conducts both hot and cold temperatures. As a result, regulating your home’s interior temperatures might cost you more money.

2. Wood

Wooden window frames are the best choice for a traditional appearance that accentuates the attractiveness of ancient and classical homes. Depending on the type of wood, paint, and stain you select, they can be made in a variety of styles.

One of the disadvantages of wooden window frames is that they are vulnerable to pests, rot, and warping. With these, they might require maintenance to keep them in good shape.

3. Vinyl

Since they are at the lower end of the pricing spectrum, vinyl window frames are both common and affordable. They also offer a number of benefits including low-maintenance, fire resistance, and energy efficiency.

On the other hand, vinyl window frames are lacking in terms of strength and beauty. Vinyl can warp in hot temperatures and is difficult to paint or stain.

4. Fiberglass

Fiberglass is a strong and weatherproof material that has more to offer compared to other material choices. No matter what the weather is, fiberglass can expand and shrink because of an interwoven proprietary blend of glass fibers and a sturdy resin core.

The primary drawback of this window frame type is its limited color and design choices. This type of material is also more expensive compared to other options. Yet, choosing this option can save you on maintenance and energy cost.

5. Composite

Composite window frames mimic the look of wood while using recycled wood, metals, or plastic to provide a more natural, sustainable product. It can be difficult to tell exactly what you’re getting because it incorporates a variety of components.

Compared to vinyl or aluminum, composite windows are more expensive. Nonetheless, they are generally less expensive than steel, wood, or clad.

6. Steel

Steel window frames provide the more industrial feel that some contemporary homes occasionally need. Steel is a fantastic material for homes wishing to increase security because it is strong, fire-resistant, and difficult to break.

This high-end alternative material is reliable, stylish, and custom-made to order. Thus, expect to pay more for steel window frames. They can endure more than 75 years and require little upkeep.

Cost of Window Glass

Just like the type of window and window frame material, the type of glass used in your windows significantly affects the total replacement costs as well. Below are the various types of window glass and their average costs per square meter.

The size and quality of the glass have an impact on the price of windows as well. Typically, windows with more and broader glass panes cost more.

On the other hand, their improved energy-efficiency ratings are well worth the cost. Due to its energy and money-saving features, your home’s interior will be more enjoyable and comfortable to live in.

Type of Window Glass	Average Costs per Square Meter
Low-E glass (low heat emission)	$195
Double-glazed glass	$210
Acoustic laminated glass	$340
Tinted glass	$40
Low iron glass	$140

Other Factors That Can Affect the Cost of Window Replacement and Repairs 

1. Materials Used

One of the first decisions you’ll make when replacing windows is the type of material to be used. Some of the most popular choices include wood, vinyl, and fiberglass.

Each of these materials has a unique set of factors to take into account, including the window type, hardware designs, and performance features that are being offered. And of course, the type of material significantly affects the cost too.

2. Installation Cost 

Although many homeowners prefer to install their own windows themselves, it’s highly recommended to employ a professional to replace your windows. It requires the right skills, equipment, talent, and rigorous attention to detail to get this job done right.

Meanwhile, installation costs can vary based on the complexity of the project. The most common type of window is a double-hung window, and most installers are very familiar with them.

Bow and bay windows, for example, may require additional reconstruction work during installation, raising the labor cost. Some windows will need a new rough opening to be framed for them, which involves removing the studs and installing new headers.

3. Warranty

The majority of window manufacturers offer a warranty on their products. Replacement windows with warranties and certifications cost more than those without. However, such a warranty ensures that any issues with your windows will be resolved.

Steps on How to Install Insert Replacement Windows

If you’re looking to replace your windows, you may be wondering how to go about installing them. Here, we’ll take the installation of insert windows as they are one of the most common window replacements. Keep reading for the step-by-step guide.

What are insert windows?

Insert windows are a type of window that is installed into an existing opening. They are commonly used as a replacement for an older window or to add additional light and ventilation to a room.

Insert windows are available in various sizes, shapes, and materials. They provide the perfect solution for those who want to add extra light, ventilation, or style to their home without having to replace the entire window frame.

1. Measure and Order the Window 

Measure horizontally and vertically from the inside of one window jamb to the inside of the other jamb at the bottom, center, and top. When ordering the window, go with the smallest measurement available.

The replacement window’s size in relation to your window opening will be specified in the manufacturer’s instructions. Often, the window unit is a little smaller in order to fit into the opening.

You may consult a window specialist at your local home improvement store if you are unsure about sizing. This will help you to avoid costly errors like incorrect window measurement.

2. Carefully Remove the Window Stops

To gently remove the window stop molding from the sides and top of the window frame, you can use a pry bar, putty knife, and hammer. Take note that screws may be used to fasten some moldings.

Carefully peel the molding away from the window frame. If it has been painted in place, cut through the paint with a utility knife.

The stop moldings might be reusable if you carefully remove them before installing the new insert window. However, it might be better to buy and install new moldings if the stop moldings are already brittle and old.

3. Remove the Inner Window Sash

Remove the inner window sash from the opening with care. Then, take the knotted weight cords out of the holes in the side of the window sash frame. The sash cords may sometimes be fastened into the sash frames.

4. Pull Out the Parting Stops

The little parting stop moldings that divide the inner window from the outside window sash can be removed with a small pry bar or screwdriver. It’s ok to break these to release them from the window frame because they won’t be used again.

5. Remove the Outer Sash

The outer window should now slide out of the window frame after the parting stops have been removed. To remove the sash frame from the sash cords, pull the knots out of their openings on the sides.

6. Extract the Counter Weights and Pulleys

The hefty weights can be removed by opening the weight compartments on the window frame’s sides. Use a utility knife to cut the sash cords, then take the cords out.

At the top of the window frame, unscrew the weight pulleys. Discard the pulleys, ropes, and weights. However, do not throw away the metal weights and pulleys in the trash. Instead, deliver them to a recycling facility.

7. Insulate the Weight Pockets

Fiberglass insulation should be loosely put into the weight pockets. Take note that these empty spaces can be a significant source of heat loss. Thus, the energy efficiency of the windows will be significantly increased by insulating these pockets.

On the other hand, the weight pockets’ coverings should be replaced. Then, they should be screwed on.

8. Test the New Window’s Fit

Attach any necessary expansion strips or headers to the new insert window. Then, test fit the new window in the frame opening and loosely shim it into place.

Ensure that the window is level and square. You can make the appropriate adjustments by using a carpenter’s square and torpedo level.

9. Put the New Window in Place

As soon as you are certain that the new window fits correctly, remove it from the opening. Then, follow the instructions on caulking the window frame. Reinstall the new window and ensure it’s level and plumb by using a framing square and torpedo level.

Shims can be used to temporarily secure the window. Test for smooth sliding on both sashes. Use the adjustment screws found in the side channels to adjust the operation if the sashes are too tight.

You might need to take off the shims and use thinner shims if this doesn’t resolve the issue. Drive mounting screws through the side channels and into the window frame to fasten the window once it is in place and once the sashes move freely.

The screw-driving holes are already drilled into the majority of insert windows. Don’t overtighten these screws as this could cause the sash frame to become out of square. Shims should be removed to make them flush with the sash frame.

10. Seal the Joints

To close the gaps, raise the header piece at the top of the window. Then, fill the joints on the exterior and interior of the window with the suggested caulk.

Make sure to carefully follow this manufacturer’s directions. Certain windows need to have a drainage gap left at the bottom sill.

Choose a paintable caulk if you need to paint over the wood trim. The majority of latex caulks can be painted, while pure silicone caulk cannot.

11. Reattach the Window Stops

Using a brad nailer or screws, reattach the window stops around the new insert window’s sides and top. Use a miter saw to cut new stop moldings to size if you plan to use them. It’s also better to paint or stain them before installing. 

12. Caulk and Paint

Caulk the joints around the stop moldings to complete the installation. Then, you can do the final touches such as painting if necessary.
