At JP Exteriors, we’re seeing brands like Andersen, MI Windows, and Simonton increase prices by approximately 7% across the board, following similar increases from Pella earlier this spring.

If you’ve been considering window replacement for your home in Austin, Round Rock, Georgetown, Cedar Park, Leander, Lakeway, Bee Cave, Dripping Springs, or surrounding areas, now may be the right time to move forward.

Several major window manufacturers are implementing significant price increases starting June 1st, continuing a trend we’ve already seen throughout 2026 across the window industry.

For homeowners researching replacement windows, fiberglass windows, vinyl windows, or energy-efficient window upgrades, understanding which brands are increasing — and which brands have not yet followed — can potentially save thousands on larger projects.

Which Window Brands Are Increasing Prices?

As of June 1st, we’ve been notified of upcoming pricing increases from:

• Andersen Windows

• MI Windows

• Simonton Windows

Most increases are landing around 7% depending on the product line and configuration.

This follows Pella’s pricing adjustment back in April, which impacted several popular product lines including:

• Pella Impervia

• Pella 250 Series

• Pella Lifestyle

• Pella Reserve

Unfortunately, these increases have become common throughout the construction and remodeling industry due to:

• Material cost increases

• Labor shortages

• Glass manufacturing costs

• Freight and transportation expenses

• Continued demand for replacement windows

Which Window Brands Have NOT Increased Yet?

Interestingly, several staple window brands we sell at JP Exteriors have not yet announced broad June pricing increases.

At the moment, Marvin and NT Windows remain some of the strongest overall values in the market.

That’s one reason we’re currently recommending homeowners take a close look at products like:

• Marvin Essential

• Marvin Elevate

• NT Presidential Series

• NT Executive Series

These product lines still offer premium performance and strong energy efficiency without some of the recent pricing jumps we’re seeing from competing manufacturers.

Of course, no one knows how long that will last.

Historically, once several major manufacturers raise prices, others often follow within the same quarter.

What Does This Mean for Austin Homeowners?

For many homeowners, the difference may not sound huge at first.

But on a full-house window replacement project, even a 7% increase can add several thousand dollars depending on:

• Number of windows

• Window sizes

• Custom configurations

• Black exterior upgrades

• Fiberglass vs vinyl materials

• Specialty glass packages

On larger projects in areas like Westlake, Lakeway, Bee Cave, and Dripping Springs, the pricing impact can become significant very quickly.

Should You Replace Windows Before the Increase?

In many cases, yes.

If window replacement is already on your radar for 2026, locking pricing in before additional increases can provide meaningful savings.

This is especially true for homeowners planning:

• Full-home window replacement

• Black fiberglass windows

• Custom sizing

• Large sliding doors

• Patio door replacements

• Energy-efficiency upgrades

Even if installation happens later, many projects can secure current pricing once contracts are finalized.

Are Fiberglass Windows Still Worth It?

Absolutely.

Fiberglass windows continue to grow in popularity across Central Texas because they handle extreme heat and UV exposure far better than standard vinyl.

Compared to traditional vinyl windows, fiberglass offers:

• Better structural stability

• Less expansion and contraction

• Improved longevity

• Larger glass areas

• Better performance with dark exterior colors

That’s why products like Pella Impervia and Marvin Essential continue to dominate higher-end replacement projects throughout Austin.

What Should Homeowners Look For Besides Price?

Pricing matters, but installation quality matters just as much.

When hiring a window contractor Austin homeowners should prioritize:

• Proper flashing methods

• Waterproofing details

• Manufacturer-certified installation practices

• Experience with fiberglass systems

• Clear warranty support

• Local reputation

The best window in the world can still fail if installed incorrectly.
