How To Calculate The Cost Of A Window Replacement Project?


Window Replacement

Are you interested in starting a window replacement project? These projects seem like a challenging undertaking for most homeowners, mainly due to the financial aspect of such replacements.

Before undertaking such a project, homeowners are advised to calculate the approximate cost of getting their windows replaced. There are numerous factors that influence the overall project price, such as the size, location, frame material, and type of windows. Make sure to check out this cost calculator to discover how much your window project will cost.

Read more about each factor that influences the price.

Consider The Size And Location

The inceptive factors to consider when calculating the cost of such a project are the size and location of the windows. Normally, the size is an obvious factor affecting the final price. The larger the window, the higher the price. Although the dimensions cannot always be controlled, there are several options that you can use to control the cost.

For instance, if your budget is concerned, you can opt for a model with smaller frames instead of large ones. Consequently, the cost will be at least slightly reduced. Another factor that affects the ultimate price is the location of the windows. Those installed in the basement are significantly more expensive, along with those installed on the second and third floors of multi-story homes. The installation expenses are higher because of the longer time it takes for installation to be completed.

Consider The Frame Material

Another major cost factor that has an enormous effect on the price of window replacement projects is the frame material. The choice of material narrows down the brand options available to buyers, as well as impacts the cost of long-term maintenance. The best replacement advice is to get windows with a frame material of higher quality to prevent property value loss.

Aluminum models are the most affordable but not incredibly common in residences due to their lack of versatility. They are durable and low-maintenance but less energy-efficient than wooden frames. The average upfront costs range between $100 and $400 per unit, which makes them perfect for budget-conscious homeowners.

Vinyl is another popular frame material, which is both low-maintenance and budget-friendly. Vinyl models offer excellent energy efficiency and a classic look that suits both the interior and exterior of homes. Homeowners are expected to pay from $400 to $600 for a double-pane, double-hung model. The only drawback of vinyl frames is that the colour might fade over time.

Wooden frames are the most traditional alternative and among the costliest ones at the same time. Homeowners choosing wood as a frame material would pay from $200 to $1,000 per unit, including installation. The exact choice of wood species has the greatest influence on the price, as some types of wood are more expensive than others.

Moreover, homeowners should know that wooden frames require the most maintenance, frequent repairs, and touch-ups. These frames are likely to contract and swell when exposed to exterior elements, meaning they need regular maintenance to remain in optimal shape. On the positive side, wood provides impeccable temperature insulation. Visit the following link,, to see some tips for painting a window frame.

Composite frames are pricier than vinyl but more affordable than wood. They are made from a combination of PVC polymers that offer the best of wood and vinyl fibers. Their price is between $500 and $800 per unit. However, they require virtually no maintenance after being installed.

Fiberglass windows, on the other hand, share most of the advantages of vinyl models, but they are even more robust. Fiberglass frames are energy-efficient and capable of enduring both extremely cold and hot temperatures. Their price tag per unit is between $800 and $1,200.

Probably the most expensive alternative for homeowners is getting clad window frames. Their average price range is between $300 and $2,000 for a single unit. These frames are specific for their vinyl exterior and wooden interior. Since the interior is made of wood, there is greater energy efficiency. As a result, less cold and heat will pass through the frame from the outside.

Consider The Type

Another factor taken into consideration during cost estimates for such replacement projects is the type of window. Picture windows are standard fixed models whose size and shape can be customized. Hence, their price ranges from $300 to $800, including installation. In contrast, single-hung models are the most old-fashioned type, with a top sash that’s fixed and a bottom sash that’s operable. They cost between $100 and $500 per unit.

Double-hung windows are the standard model in most homes. Both the upper and bottom sash are operable. Therefore, they are excellent for providing the best air circulation. Although the exact cost depends on the material, a typical double-hung model is worth on average $300 to $600.

Casements come with a hand crank and a lock for security. Casements hinged to the top are called awnings, whereas those hinged to the bottom are called hoppers. The average price per unit starts from $300 and reaches $1,000. Conversely, sliding models, also known as gliders, are a more expensive alternative worth from $200 to $2,000.

Another common type of window that homeowners replace is the skylight. Skylights require more labour to install, meaning they are relatively costly to replace. The replacement cost ranges from $900 to $2,400, depending on size, operability, and location.

Last but not least, storm windows refer to the additional glass pane installed on the exterior surface of your existing windows. Their role is to provide better protection against storm damage, as well as extra insulation. This glass pane can be installed as a permanent layer or a temporary addition. Such a protective glass pane is $150-450 per unit.
