Replacement Windows & Doors Built for Gulf Coast Living

Windows may get most of the attention, but doors are just as critical in protecting your home from heat, humidity, and hurricanes. LAS provides a full range of entry and patio doors designed for long-term performance in the Gulf South climate. 

Fiberglass Entry Doors 

We proudly offer Therma-Tru® fiberglass doors that are engineered to resist warping, rotting, and rusting. These doors mimic the look of real wood while offering superior durability and insulation. Their polyurethane core provides excellent thermal performance without the upkeep of traditional wood. 

Sliding Glass Patio Doors 

Our sliding patio doors are manufactured in-house using the same high-performance vinyl and insulated glass as our windows. Designed to glide smoothly and seal tightly, these doors are built to handle heavy rains, high humidity, and harsh sunlight. Multi-point locking systems offer added security while maintaining a clean look. 

We control every step of the process for the windows we build, from precision measurement to final installation. That level of ownership ensures reliable performance and peace of mind. 

Exact Measurements 

Every opening is measured by a factory-certified LAS technician to the 1/16 inch. We assess squareness, wall depth, and framing conditions to ensure your new unit is the perfect fit. 

Custom Fabrication 

Each vinyl window is custom-built in our Louisiana facility. We cut, weld, and glaze everything in-house, then inspect for fit, finish, and performance before delivery. 

Professional Installation 

AAMA-trained crews remove old frames without damaging trim, set new windows plumb and level, insulate gaps with low-expansion foam, and seal per ASTM C920 using OSI QUAD MAX sealant. 

Hassle-Free Support 

Because we make what we install, you call one number for service. We include a limited lifetime warranty on vinyl frames and hardware, 10 years on insulated glass, and 5 years on service labor. 

Why Gulf Coast Homeowners Choose LAS Over National Brands 

When it comes to windows and doors built for the unique challenges of the Gulf South, LAS delivers lasting performance and unmatched local expertise. Here’s what sets us apart: 

• Designed for the Gulf South: Every window is engineered to withstand our region’s intense heat, humidity, and storm conditions—meeting strict wind and impact codes. 
• Manufactured Locally: All LAS products are made in-house at our Louisiana facility, giving us full control over quality, consistency, and innovation. 
• Energy-Efficient by Design: LAS windows exceed Energy Star Version 7.0 standards, thanks to features like multi-pane construction and Cardinal® LoĒ³-366 E-glass. 
• Expert Installation: Our certified installers use industry-leading OSI QUAD MAX sealants and follow advanced protocols to ensure long-term performance. ]
• Proven Craftsmanship: With over 65 years of service and support behind every product, LAS is trusted across the region for reliability and results. 

Homeowners typically recoup 69 percent of project cost at resale (Remodeling 2024 Cost vs. Value Report) and enjoy average annual energy savings of $300–$450 for a 2,000-sq-ft home. 

Financing & Incentives for Gulf Coast Window Projects 

Upgrading every window in a home is a major spend, but LAS partners with Synchrony Financial to make budgets easier on cash flow. Synchrony is the nation’s largest provider of private-label credit programs and offers: 

• A simple online application and fast credit decisions 
• Unsecured revolving credit lines (subject to approval) 
• Convenient monthly payment options with promotional financing
• Competitive interest rates and no pre-payment penalties 

Ask your LAS project consultant financing through our partner when you schedule your estimate. 

Vinyl needs far less upkeep than wood or aluminum, but a modest maintenance routine will keep those energy-efficient windows operating like new for decades—an important point if you ever transfer LAS’s limited lifetime warranty to a new homeowner. 

Seasonal Maintenance Checklist 

Spring and fall are perfect moments to give windows a quick once-over: 

1. Clean frames and glass with a mild dish-soap solution; avoid abrasive pads that can dull the PVC finish. 
2. Inspect caulk lines for UV cracking. The Gulf Coast sun is brutal. Touch up with color-matched QUAD MAX if you notice gaps. 
3. Flush weep holes using a plastic drinking straw and garden hose set to gentle flow; this prevents water back-ups during torrential downpours. 
4. Lubricate locks, rollers, and hinges with a silicone-based spray. Never use petroleum oil, which attracts dust. 
5. Check sash balance tension on double-hung units; if a sash creeps down, call LAS for service. If your windows are still within the labor warranty period, adjustments may be covered. 

Storm-Season Preparation 

Between June 1 and November 30, the Gulf South swings into hurricane readiness mode. To maximize the impact-resistant performance of your LAS windows and doors: 

• Close and lock every operable unit; engaged cam locks pull sashes tighter against weatherstripping. 
• Remove loose patio items that could become wind-borne projectiles. Even the strongest laminated glass benefits when debris risk is reduced. 
• Document current condition with timestamped photos on your phone. If you ever need to file an insurance claim, “before” images streamline approval. 

When to Call LAS Service 

Because LAS is the manufacturer, most service visits resolve minor issues, like a sticky slider track, in a single trip. Reach out if you notice: 

• Persistent condensation between panes (a sign the IG seal has failed). 
• Difficulty latching or unlocking a sash after frame settling. 
• Unexplained drafts around the jamb or sill. 

Service calls for windows are free for workmanship issues within the labor warranty period, and our vans stock factory-original parts for on-the-spot fixes. After the 5-year labor warranty expires, we cover materials under warranty, but service labor is charged at an hourly rate. 

Your house faces enough challenges: the sweltering sun, sideways rain, and hurricane winds. Give it an edge with LAS replacement windows and doors engineered to thrive where others fail. Schedule a no-pressure consultation, and our experts will bring samples, take precision measurements, and craft a custom proposal that fits your budget and design vision.
