Tips for Installing Replacement Windows Before the Fall

As summer starts winding down, many homeowners and business owners begin preparing their properties for the colder months ahead. One crucial upgrade that often gets overlooked is installing replacement windows before fall sets in. Whether you’re managing a residential space or dealing with commercial windows and doors, early replacement can save money, increase comfort, and improve long-term energy efficiency.

In this blog, we'll walk you through expert tips for replacing windows before fall ensuring a smooth process and long-term results.

Why Fall Preparation Is Essential

Fall brings cooler temperatures, unpredictable rain, and increasing energy bills if your property is not properly sealed. That’s why late summer is the ideal time to plan window replacement:

Avoid weather delays: Early preparation means avoiding autumn rains or storms that can delay installation.

Energy efficiency: New windows offer better insulation before winter's chill sets in.

Scheduling flexibility: Contractors are less busy now than they will be in the peak fall season.

Choose the Right Type of Windows

Before jumping into the installation, consider the material and style that best suits your property. For commercial buildings, windows need to strike a balance between durability, aesthetics, and energy performance.

Common Replacement Window Options:

Vinyl Windows: Low-maintenance and affordable.

Fiberglass Windows: Highly durable and excellent insulators.

Wood Windows: Offer a timeless look but require more upkeep.

For commercial buildings, combining energy-efficient glass with reinforced framing is key. A trusted supplier can guide you based on your needs. Explore real-world insights on modern window options from Energy.gov.

Consider Energy Efficiency Ratings

Fall and winter can bring extreme temperature drops. To keep your indoor environment comfortable, prioritize energy-efficient features such as:

Low-E glass  Double or triple-pane construction

Argon or krypton gas fills

ENERGY STAR® ratings

Commercial properties, in particular, benefit from thermal performance, reducing HVAC strain and utility costs in colder months.

Plan for Minimal Downtime

For businesses, downtime can mean lost revenue. That’s why scheduling and project management matter. The right team will:

Coordinate installation in non-peak hours

Complete jobs in phases to avoid full closure

Clean up thoroughly after work is completed

A smooth, non-intrusive process keeps your operations running without disruption.

Don’t Forget Doors

While windows get most of the attention, fall is also an ideal time to assess and replace outdated commercial doors. Doors are equally crucial for:

Security

Energy insulation

Aesthetic appeal

Matching commercial windows and doors can create a cohesive, modern look for your business while improving functionality. Understand Local Regulations

Many municipalities have building codes and energy efficiency requirements. Commercial properties often require permits for upgrades. A reputable company like McDowell Glass will:

Handle all paperwork

Coordinate with city inspectors

Ensure all upgrades meet legal standards

Avoid fines and delays by partnering with experts who understand local rules.

Ask About Warranties

Warranties protect your investment. Look for manufacturers and installers who provide:

Product warranties 

Labor warranties 

Before signing, always clarify what is covered especially for commercial projects, where wear and tear can be higher.

Inspect Seals and Frames

Sometimes, the glass isn't the issue it's the frame or seal. Before replacing the entire unit, ask your installer to inspect:

Cracked caulking

Rotting or warped frames

Moisture between panes

Air drafts

Minor repairs might be all you need, or it might confirm that a full replacement is necessary.

Don’t Wait Until It’s Cold

The biggest mistake property owners make is waiting too long. Once fall arrives in full force, it’s harder to schedule, install, and seal windows effectively. Cold temperatures can affect the sealants used during installation, potentially leading to:

Poor insulation

Condensation issues

Higher long-term costs
