Windows and Shutters in Mandeville, LA

Whether you are replacing aging windows, renovating a historic cottage, or choosing windows for a new build, you want them to look right and perform through our long Louisiana summers. For lakefront and view-oriented homes, windows also have a bigger job than usual: they need to let in light and views while keeping out as much heat as possible.

Here's what Mandeville homeowners can expect when planning a window project with LAS:

• A custom fit for every kind of home: Older cottages rarely have perfectly square openings, and newer homes often include oversized, arched, or specialty shapes. LAS measures each opening individually and manufactures the window to fit it, with no stock sizes forced into place.
• Less heat through the glass: Our WeatherGard windows use Low-E glass technology designed to reduce solar heat gain, which matters most on west- and south-facing windows that take the afternoon sun.
• Energy-efficient performance: LAS windows exceed ENERGY STAR requirements for the Southern Region, and our WeatherGard line carries some of the lowest Solar Heat Gain Coefficient (SHGC) scores in the region. Our energy-efficient windows are built for the long summer season.
• Views that stay bright: The goal is to manage heat without making your rooms feel dim. Our team can walk you through glass options so you get the balance of comfort and natural light that suits your home.
• Grid patterns that suit your home's style: Whether you want a traditional look for a historic cottage or a cleaner, simpler window for a modern home, our team can help you choose a grid pattern and explain which options look best with Low-E glass.
• Low-maintenance frames: High-quality vinyl frames hold up in humid, tree-shaded conditions where wood can swell, rot, or need repeated painting.
• Storm-ready options: Every LAS window meets or exceeds the wind requirements for our region. For large view windows and openings facing the lake, our WeatherGard III hurricane windows are Florida Building Code compliant and add wind and impact protection.
• Flexibility to work in phases: If replacing every window at once is not the right approach, our team can help you decide which openings to tackle first.
• One team from start to finish: LAS designs, manufactures, installs, and services our products, so a local team is here for the life of your windows.

Our goal is not simply to put new windows in your house. It is to help you choose windows that make your home more comfortable, suit its style, and work for the way you plan to live there for years to come.

There is a real difference between windows and shutters designed for the Gulf South and ones designed somewhere else and shipped here. Mandeville homes deal with months of heat and humidity, heavy rain, and hurricane-season winds. Products made for a national market are not built around those conditions. Ours are.

LAS has been serving the Gulf South since the 1950s, and our manufacturing facility sits right here in Louisiana. Our installers are LAS employees, not subcontractors. Our service team handles warranty questions directly. There is no national call center and no confusion about who is responsible when something needs attention.

That history gives our team perspective. We have worked on historic Louisiana homes with unusual openings, lakefront homes with large expanses of glass, and newer construction with custom specifications. We understand that homeowners care just as much about the look of a house as its storm protection or efficiency, and we plan our projects with all three in mind.
