Why New Construction Windows Over the Last 20 Years Are Low Quality

When it comes to new construction residential homes and apartment complexes, windows are often one of the most overlooked components. Builders and general contractors prioritize cost savings, which typically results in the installation of the cheapest, lowest-grade windows available.

While this practice may save the builder money upfront, it leaves homeowners with subpar windows that compromise energy efficiency, soundproofing, and aesthetics.

Here’s a deeper look at why new construction windows are low quality and why upgrading windows can make all the difference. 

 

Poor Practices in New Construction 

The Austin housing market has boomed in the past two decades, with tens of thousands of homes built to accommodate the city’s rapid growth.

According to recent statistics, the average home in Austin is approximately 26 years old, and a significant portion of these homes were built within the last 20 years. Unfortunately, many of these new homes share a common problem: low-quality windows installed with poor workmanship. 

In new construction, the focus is almost always on cost efficiency. General contractors often hire framers—the lowest-cost labor in the construction process—not only for framing but for window installation.

This practice leads to issues, as framers, though fast and inexpensive, lack the expertise needed for proper window installation.

To cut costs further, builders frequently select the cheapest vinyl windows on the market, such as Ply Gem, which are designed to last only about 20 years under ideal conditions. 

In Austin, where temperature swings can be dramatic, vinyl windows are subjected to constant expansion and contraction. This significantly shortens their lifespan, especially when improperly installed, which is often the case.

At JP Exteriors, we’ve seen countless homes with these low-grade windows fail in as little as 5–7 years after installation due to poor quality and workmanship. 

 

 The Drawbacks of New Construction Windows

• Low-Quality Materials: New construction windows are typically made with the cheapest materials to save money. Vinyl frames are thin, seals are weak, and glass is single or basic double-pane with minimal insulation properties. These windows may look fine at first but degrade quickly under stress.
• Improper Installation: Windows installed by unskilled laborers often suffer from improper leveling, sealing, and flashing. These mistakes lead to drafts, water intrusion, and warping over time. Many homeowners in Austin have had to replace their windows just a few years after moving in due to these issues.
• No Emphasis on Quality: Builders rarely prioritize window quality during construction. General contractors focus on proposals that keep costs low, with little regard for how windows will perform over time. While some homes may specify a particular window brand and series, this is the exception rather than the rule.
• Limited Lifespan: Even if properly installed, an average vinyl window in Austin’s climate struggles to last beyond its intended 20-year lifespan. Poor installation and the area’s wide temperature swings only accelerate the degradation.

 

The Benefits of Replacing Your Windows

Upgrading your windows is one of the best investments you can make for your home. Here’s why: 

• Improved Energy Efficiency: Modern windows are designed to keep your home cooler in the summer and warmer in the winter, reducing energy bills. High-quality brands like Andersen and Pella offer advanced technology that outperforms builder-grade windows by a wide margin.
• Enhanced Sound Dampening: Premium windows provide superior noise reduction, making your home quieter and more comfortable, especially important in a bustling city like Austin.
• Return On Investment: Replacing your home’s windows can yield a substantial return on investment. According to Remodeling Magazine’s 2024 Cost vs. Value report, homeowners can expect to recoup ~ 75% of the cost of new windows upon resale.
• Curb Appeal: New windows can completely transform the look of your home, increasing curb appeal and resale value. Options like black-framed windows, custom shapes, or new larger openings allowing you to tailor the style to your preferences.
