How Long Does It Take to Install Windows?

Learn how long it takes to install windows, from single replacements to full home projects. Discover factors that affect installation time and efficiency.

The time it takes to install windows can vary depending on several factors, such as the type and number of windows being installed, the complexity of the project, and the expertise of the installer. On average, a professional installer can fit a standard window in 1.5 to 2 hours, meaning a full day’s work can cover around 6–8 windows. Larger or more intricate projects may take longer.

At Dale Joinery, we design bespoke timber windows that are precision-engineered for seamless installation. Here’s what to consider when planning your window installation.

Factors That Affect Installation Time

Number of Windows

A single window can be replaced in a few hours while replacing all the windows in a home might take a professional team 2–3 days.

Window Type

Casement Windows: Typically straightforward and quick to install.

Sash Windows: These may take longer due to their intricate design and balancing mechanisms.

Bespoke Designs: Custom windows may require additional care and adjustments during installation.

Property Type

Older properties or homes with uneven walls may require more preparation, such as adjustments to window openings.

Multi-story homes or hard-to-reach windows may extend installation time due to access challenges.

Preparation and Removal

Removing old windows and prepping the openings takes additional time. If the existing windows are in poor condition, the installer may need extra time for repairs or adjustments.

Weather Conditions

External factors like heavy rain or extreme cold can delay installation, as they impact the use of certain tools and materials.

The Installation Process

Preparation: The installer protects the area, removes old windows, and checks the openings.

Fitting: The new windows are securely installed, sealed, and adjusted to ensure proper functionality.

Finishing Touches: Trims and finishing work are applied for a polished look, and the area is cleaned up.
