Inside vs. Outside Installation- The Ultimate Guide to Replacing Windows

Do you install replacement windows from the inside or outside? This question often arises when homeowners are considering replacing their windows. The answer to this question can significantly impact the installation process, the time it takes, and the final appearance of the windows. In this article, we will explore the advantages and disadvantages of installing replacement windows from the inside or outside, helping you make an informed decision for your home improvement project.

Installing replacement windows from the inside is a common method, especially for single-hung or double-hung windows. This approach involves removing the old window sashes from the interior, installing the new windows, and then replacing the sashes. The benefits of this method include:

1. Less disruption: Installing windows from the inside minimizes the disturbance to the home’s interior, as there is no need to remove the entire frame or the exterior siding.
2. Easier access: For homeowners who have limited space outside their homes, installing windows from the inside is a more convenient option.
3. Cost-effective: Generally, installing windows from the inside is less expensive than removing the entire frame and exterior siding.

On the other hand, installing replacement windows from the outside is often used for casement, awning, or sliding windows. This method involves removing the entire frame and exterior siding, installing the new windows, and then restoring the exterior. Here are some advantages of this approach:

1. Easier for larger windows: Installing larger windows from the outside is often easier and more practical than trying to maneuver them through the interior.
2. Better seal: When installing windows from the outside, it is easier to ensure a proper seal between the new window and the frame, which can improve energy efficiency.
3. Less interior mess: By working from the outside, the mess is contained to the exterior of the home, reducing the risk of damage to interior floors and furniture.

However, there are also some disadvantages to consider when installing replacement windows from the outside:

1. More disruption: Removing the entire frame and exterior siding can be more disruptive to the home’s structure and may require additional repairs.
2. More expensive: The process of removing and reinstalling the exterior siding can add to the overall cost of the project.
3. More time-consuming: Installing windows from the outside typically takes longer than installing them from the inside.

In conclusion, the choice between installing replacement windows from the inside or outside depends on various factors, such as the type of window, the size of the window, the amount of disruption you are willing to endure, and your budget. It is essential to weigh the pros and cons of each method before making a decision. Consulting with a professional window installer can help you determine the best approach for your specific situation.
