The Right Order for Replacing Windows and Siding

Why Sequence Matters

When planning a major exterior renovation, one of the most common questions homeowners ask is whether to replace their windows or siding first. The order of these projects directly affects the efficiency, cost, and overall quality of the results. For homeowners in Fort Wayne, IN, where weather conditions put extra demands on a home’s exterior, getting the order right is essential for long-term protection and value.

The Case for Replacing Windows First

Ensuring Proper Fit and Seal

Installing new windows before siding allows contractors to correctly fit and seal them. This prevents gaps that could lead to drafts, leaks, and higher energy bills.

Avoiding Redundant Work

If you replace siding first and then install new windows, contractors may have to cut into freshly installed siding to adjust openings. This could compromise the siding’s integrity and add unnecessary costs.

Better Energy Efficiency

New windows immediately improve insulation and energy savings. Replacing them first allows you to maximize efficiency before new siding is installed to complete the protective envelope.

The Case for Replacing Siding First

Severe Siding Damage

If your siding is failing and exposing your home to water intrusion or pests, immediate siding replacement may take priority. Delaying could cause costly structural damage.

Budget and Timing

In some cases, homeowners may choose to replace siding first if windows are still in good condition. However, it is generally recommended to coordinate both projects for best results.

The Ideal Solution: Coordinating Both Projects

Comprehensive Planning

The best approach is to plan window and siding replacement together. By doing so, contractors can sequence the work efficiently, ensuring windows are installed first, followed by siding.

Long-Term Protection

Coordinating both projects ensures your home is fully sealed against the elements. New windows prevent drafts, while new siding provides strong weather

resistance and enhances curb appeal.

Streamlined Installation

Working with one contractor for both windows and siding allows for better project management, consistent workmanship, and reduced labor costs.

Choosing the Right Materials

Energy-Efficient Windows

Modern windows with insulated glass and advanced sealing technology reduce energy loss and improve comfort. Choosing energy-efficient models is especially beneficial in Fort Wayne’s cold winters and hot summers.

Durable Siding Options

Siding materials such as James Hardie fiber cement, vinyl, metal, or engineered wood each offer unique benefits. Fiber cement provides unmatched resistance to moisture and pests, vinyl is affordable and low-maintenance, and metal offers superior strength and longevity.

Preparing for the Project

Professional Assessment

Start with a professional evaluation of your siding and windows. Contractors can help determine which project is more urgent and provide a clear plan for sequencing.

Budget Considerations

Replacing both siding and windows is a significant investment, but coordinating them together may reduce overall costs in the long run. Detailed estimates help homeowners plan accordingly.

Timeline Expectations

A typical window replacement project takes a few days, while siding replacement can take one to two weeks. Coordinating the timeline ensures minimal disruption.

Why Professional Installation Matters

Improper installation of either siding or windows can lead to air leaks, water damage, and reduced efficiency. Working with a professional contractor ensures both projects are completed to the highest standards.
