Replacement Windows in New Orleans and the Gulf South

Drafty, fogging, or aging windows cost more than you'd think. LAS has built and installed replacement windows for the Gulf South since 1957.

If your windows are drafty, fogging up between the panes, or driving your energy bills higher every summer, it's probably time to replace them. LAS has built and installed replacement windows for New Orleans, Baton Rouge, the Northshore, and the greater Gulf South community since the 1950s, helping homeowners lower their energy bills, cut outside noise, and keep their homes cooler through the hottest months. Every window is custom measured, manufactured right here in Louisiana, and installed by our own certified crews, not a subcontractor.

Why Replacement Windows Are a Great Investment

Windows take more abuse in the Gulf South than almost anywhere else in the U.S. Between the heat, humidity, and storms, it doesn't take long before aging windows start working against you instead of for you. Here's what you can expect with new replacement windows:

  • Comfort: Drafty windows let outside air in year-round, leaving rooms too hot in summer and too cold in the rare cold snap. New windows seal properly, keeping the temperature where you set it.
  • Energy efficiency: If your energy bills have crept up without an obvious reason, your windows may be to blame. Old seals and single-pane glass force your HVAC system to work harder just to keep up, and that shows up on your bill every month. If you're noticing the signs it's time to invest in replacement windows, rising energy costs are usually the first clue.
  • Storm protection: Standard windows are one of the weakest points in a home during hurricane season. Impact-rated hurricane windows are built to withstand wind-borne debris and pressure changes that would shatter ordinary glass.
  • Noise reduction: Multi-pane, insulated glass doesn't just block heat, it blocks sound. Homeowners near busy streets or under flight paths often notice the difference immediately after installation.
  • Aging or damaged windows: Fogging between panes, wood rot, warped frames, and windows that stick or won't stay open are all signs your current windows have reached the end of their useful life.

You'll work with our local team every step of the way

Window Options: Styles, Glass, and Storm Protection

LAS manufactures a full range of replacement windows to match your home's architecture and functional needs:

Every window can be built with dual-pane, argon-filled glass and Low-E coatings to block solar heat while letting in natural light. For homes needing extra storm protection, impact-rated hurricane glass is available across most styles, meeting or exceeding Florida Building Code standards.

Which material holds up best in Louisiana? Here's how the most common frame materials compare:

Material Durability Upkeep Our Take
Vinyl Excellent, won't warp or rot Low Best balance of value, efficiency, and performance
Wood Can warp or swell in humidity High Beautiful but impractical for our climate
Aluminum Prone to corrosion in coastal air Moderate Poor thermal insulation and corner integrity

We don't use aluminum or wood frames because they simply don't hold up in our climate. LAS replacement windows use fusion-welded vinyl frames for long-term performance, lower energy bills, and easy upkeep.

Built for Gulf South Heat, Humidity, and Storms

Louisiana's climate is hard on windows in ways most national manufacturers don't design for. Intense heat and humidity stress seals and frames year-round, while hurricane season puts every window to the real test.

  • Heat and humidity: Our windows are engineered to hold their seal in Gulf South conditions, resisting the warping, swelling, and seal failure that cheaper windows develop within a few years here.
  • Storm performance: Windows are one of a home's most vulnerable points during a storm. LAS windows are built with impact-rated glass options, reinforced vinyl frames that resist rot and corrosion, and fusion-welded corners for superior water and air sealing.
  • DP and impact ratings: Every window is rated for Design Pressure (DP), a measurement of how much wind load and structural stress the window can withstand. Our impact-rated glass meets or exceeds Florida Building Code standards for wind-borne debris.

We don't use aluminum or fiberglass frames that corrode or separate over time. Instead, we use vinyl windows with welded corners built specifically for Louisiana, Mississippi, and Alabama conditions, not generic products shipped in from cooler climates.

Replacement Windows Cost and Financing

Replacement window costs vary based on the number of windows, style, glass package, and whether you choose impact-rated hurricane glass. Every LAS quote is a free, no-pressure estimate built around your home's specific needs, so you know exactly what you're paying for before any work begins.

Replacing windows is a real investment, and you don't have to pay for it all at once. LAS offers financing options to help spread the cost over time, making a full window replacement more manageable for your budget.

Many homeowners also choose to replace windows room by room or side of the house first, rather than all at once. This lets you spread out both the cost and the disruption while still working with the same team and consistent pricing throughout. Just let your LAS estimator know you're planning a phased project, and we'll build a plan around it.

Getting started is easy: just request a free, no-pressure estimate and we'll walk you through your options. And if you'd like to know a bit more first, you can hear directly from past LAS customers on how we did. We can't wait to help you plan our your next home upgrade!

FAQs: What You Should Know Before Replacing Windows


Cost depends on the number of windows, style, and glass package you choose, including whether you add impact-rated hurricane glass. Every LAS estimate is free and built around your home's specific needs, so you'll know your exact cost before committing to anything.


Most homes are completed in one to a few days depending on the number of windows and any structural adjustments needed. From your initial estimate to final installation, the full process, including custom manufacturing, typically takes several weeks.


It depends on where you live and your local building code requirements. Homes closer to the coast typically need higher wind and impact ratings. Our team can walk you through what's required or recommended for your specific address during your free estimate.


LAS stands behind both our products and our installation work with manufacturer warranties on materials and craftsmanship guarantees on the install itself. Because we manufacture and install our own windows, you're working with one company for warranty support, not passed between a retailer and a separate installer.


High-quality vinyl windows, like those from LAS, typically last 25–30 years or longer with minimal maintenance, even in hot and humid climates.


Yes, our expert teams install year-round. In fact, summer is one of our busiest seasons as homeowners prepare for hurricane weather and heat waves.


Very little. Unlike wood, vinyl won't need repainting or resealing, and it resists the warping and rot that's common in Louisiana's humidity. Periodic cleaning of the glass and tracks is typically all that's needed.


Yes. Old, drafty windows force your HVAC system to work harder to maintain temperature, which shows up directly on your energy bill. Dual-pane, Low-E glass reduces that strain significantly, and many homeowners notice a difference within the first billing cycle.


Replacement windows are designed to fit into existing window openings without removing exterior siding or trim, perfect for home upgrades and energy retrofits.
