Step One: Initial Consultation and Assessment
Every successful window replacement project starts with understanding your home’s unique needs, style, and goals. That’s why the process at Longhorn Windows begins with a free, no-obligation in-home consultation—bringing expert advice right to your doorstep.
During this visit, a Longhorn Windows specialist will thoroughly evaluate your current windows, listen carefully to your priorities, and recommend customized solutions that balance beauty, performance, and budget. Whether you’re focused on boosting energy efficiency, enhancing curb appeal, or solving specific challenges like drafts or noise, we’re here to guide you toward the best fit.
During this consultation, you can expect:
A detailed evaluation of your existing windows. We’ll inspect for signs of damage, drafts, poor insulation, condensation between panes, or operational issues, so we understand what needs improvement.
Personalized guidance on window styles, energy-saving features, and materials. Whether you're exploring fiberglass or aluminum windows, insulated windows, double- or triple-pane glass, Low-E coatings, or temperature control windows, we’ll walk you through the pros and cons to help you choose the best fit for your home and climate.
Accurate measurements to ensure a perfect fit. Precise measurements are critical for both performance and aesthetics. We’ll take thorough measurements of each window opening to guarantee your new windows will be custom-built for a seamless, professional installation.
A transparent quote with no hidden fees. You’ll receive a clear, itemized quote outlining exactly what’s included—no surprises, no pressure, no gimmicks. We believe in honest pricing so you can make informed decisions with confidence.
This consultation is your opportunity to ask questions and explore possibilities. Wondering about frame colors, specialty shapes, glass tints, soundproofing upgrades, or warranty coverage? We’re here to provide answers and expert insight. Once you’ve selected your windows, materials, and finishes, we’ll move forward with ordering and preparing for installation.
At Longhorn Windows, we’re committed to making this process simple, transparent, and tailored to your needs from the very first step.
Step Two: Custom Window Manufacturing
Once you’ve selected the perfect windows for your home, it’s time to bring your vision to life. At Longhorn Windows, every product—including specialty window styles like bay & bow windows, picture windows, and sliding windows—is custom-built to your exact specifications for a perfect fit and a smooth, stress-free installation.
We don’t believe in one-size-fits-all solutions. Instead, we work with trusted manufacturers to craft windows tailored to the precise measurements, materials, styles, and features you selected during your consultation. This personalized approach ensures that your windows aren’t just functional—they’re a flawless complement to your home’s architecture and your lifestyle.
Here’s what happens during the custom manufacturing process:
Each window is crafted to precise measurements for a seamless installation. Your energy-efficient windows are engineered down to the millimeter, minimizing gaps and ensuring a tight, secure fit that enhances insulation and weather resistance once installed.
Energy-efficient features are incorporated into every design. Whether you’ve chosen double-pane, triple-pane, Low-E coatings, argon gas fills, or UV protection, these energy-saving technologies are integrated directly into the glass and frame construction to deliver year-round comfort and reduced utility bills.
Durable materials like aluminum, and fiberglass ensure long-lasting performance. Each window is built with high-quality frame materials selected for their strength, weather resistance, and low-maintenance durability—ideal for standing up to the harsh Texas sun, humidity, and storms.
Quality control ensures flawless results. Every custom window undergoes rigorous inspection and testing before it leaves the manufacturing facility, so you can trust that your investment meets the highest standards for performance, safety, and longevity.
Manufacturing timelines may vary depending on the style, size, and custom options you choose, but our team will provide regular updates so you’re always in the loop. Once your windows are complete, we’ll schedule your installation at a convenient time—ensuring a smooth, efficient process from factory to frame.
At Longhorn Windows, custom manufacturing isn’t just about measurements—it’s about delivering windows that are tailored, reliable, and built to last.

Step Three: Scheduling and Preparing for Installation
Once your custom windows are ready, a Longhorn Windows representative will reach out to schedule your installation at a time that works best for you. We understand that life is busy, so we’re happy to coordinate a date that minimizes disruption to your daily routine. Whether you're replacing standard double hung windows or adding casement windows for improved airflow, our goal is to make the process as seamless as possible from start to finish.
Before installation day arrives, there are a few important steps you can take to prepare your home and help our crew work safely and efficiently:
Remove Window Treatments: Take down any curtains, blinds, shades, or other window coverings around the windows being replaced. This ensures our installers have clear, unobstructed access to the window frames.
Clear the Area Around Each Window: Move any furniture, wall decor, plants, or valuables at least 3-4 feet away from the windows. This provides ample workspace for our team and protects your belongings from dust or accidental damage.
Ensure Easy Access: Make sure driveways, pathways, and entryways are free of obstacles so our crew can bring in tools, ladders, and the new windows. If certain gates or doors require keys or codes, let us know in advance.
Communicate Special Concerns: If you have pets that need to be secured, alarm systems connected to your windows, or specific instructions for your home, please let us know before installation day. We want to accommodate your needs while ensuring safety for everyone.
When installation day arrives, you can expect our team to show up on time, fully equipped, and ready to work with care and precision. We’ll lay down protective coverings as needed, keep work areas clean, and aim to complete the job with minimal disruption to your home. Throughout the process, we’re happy to answer any questions and keep you informed of our progress.
With these simple preparations, you’ll help ensure a smooth, efficient installation—and soon enjoy the beauty, comfort, and energy savings of your new Longhorn windows.
Step Four: Professional Installation Process
When installation day arrives, you can rest assured knowing you’re in the hands of highly trained Longhorn Windows professionals. Our technicians bring years of experience and a commitment to craftsmanship, ensuring every window—whether standard or code compliant windows—is installed with precision, care, and attention to detail.
Here’s what you can expect during the professional installation process:
Safe and Careful Removal of Old Windows: Our team starts by carefully removing your existing windows, using tools and techniques designed to avoid damage to your walls, siding, or interior trim. We work methodically to protect your home throughout the process.
Preparation of the Window Openings: Once the old windows are removed, we thoroughly clean and inspect each window opening. Any debris, old caulking, or damaged materials are addressed to create a clean, solid foundation for your new windows. If any structural repairs are needed, we’ll communicate with you right away.
Precise Installation of New Windows: Your new custom Longhorn windows are set snugly in place with expert alignment for smooth operation and long-term performance. This includes specialty installations such as tempered glass windows in bathrooms or near doors for added safety and compliance.
Sealing and Insulating for Energy Efficiency: To enhance your home’s energy efficiency, we apply high-quality insulation and weatherproofing materials around each window frame. This critical step helps block out air leaks, reduce outside noise, and improve indoor comfort year-round. We use industry-leading sealants designed to withstand Houston’s heat and humidity.
Finishing Touches for a Polished Look: After the windows are securely installed and sealed, we complete the process by adding interior and exterior trim. This step not only enhances the appearance of your windows but also provides an extra layer of protection. We meticulously caulk and paint (if needed) to ensure a clean, seamless finish.
Throughout the installation, our team follows a strict quality control checklist to ensure every window meets Longhorn’s high standards. Every window—especially performance-focused upgrades like impact glass windows or storm-ready windows—is tested for smooth operation, secure locking, and proper fit. Before we leave, we clean up the work area thoroughly and walk you through the completed installation, answering any questions you may have.
With Longhorn Windows, you’re not just getting new windows—you’re getting expert installation that delivers long-term performance, energy savings, and beauty you can see and feel.

Step Five: Final Inspection and Cleanup
At Longhorn Windows, we believe that installation isn’t truly complete until every detail has been checked, tested, and perfected. That’s why, once your new windows are installed, our team conducts a comprehensive final inspection to ensure everything meets both our strict quality standards and your personal satisfaction.
During this step, we carefully review and test each window to confirm that it’s performing exactly as it should. Here’s what happens during the final inspection:
Operational Testing: Every window is opened, closed, and locked multiple times to ensure smooth, effortless operation. We check for proper alignment so your windows glide easily and seal securely when closed—especially important for vertically operating styles like single hung windows.
Seal and Insulation Verification: Our team inspects the weatherstripping and insulation around each window to ensure there are no gaps or weak points. This attention to detail helps prevent drafts, moisture intrusion, and energy loss—giving you peace of mind and long-term comfort.
Exterior Caulking Application: We apply a durable, weather-resistant caulking around the exterior perimeter of each window. This protective seal helps safeguard your home against Houston’s intense sun, rain, and humidity, adding years of longevity to your investment.
Once the inspection is complete and every window has passed our quality checklist, we shift our focus to restoring your home to pristine condition. Our post-installation cleanup includes:
Removal of Old Windows and Debris: We haul away your old windows, packaging materials, and any installation debris, so you’re not left with the hassle of disposal.
Cleaning of New Windows: We wipe down the glass and frames, removing fingerprints, dust, and smudges, so your windows are spotless and ready to admire.
Work Area Restoration: Our team vacuums, sweeps, and clears the work zones, leaving your home as clean—or cleaner—than when we arrived.
Before we officially wrap up, we take time to walk you through the operation, care, and maintenance of your new windows. We’ll show you how to open and lock them properly, explain any unique features, and provide tips for keeping them looking beautiful and functioning smoothly for years to come.
We encourage you to ask any final questions—our team is happy to explain anything you’re curious about. At Longhorn Windows, we’re not just focused on completing the job—we’re committed to making sure you feel confident, informed, and thrilled with the results.
