Our Window Replacement Process

1. In-Home Consultation

Every window replacement begins with a personalized free consultation. One of our experienced design consultants will visit your San Antonio home to evaluate your current windows and doors, identify problem areas, and help you choose from our wide selection of top-quality products. We’ll guide you through frame styles, finishes, glass options, and even talk through door replacement options.

2. Custom Measurements

Once you’ve chosen the ideal products, our technicians will return to take precise measurements of your existing home’s windows. This part of the installation process ensures your new windows are custom-built to fit perfectly into your home’s architectural openings, helping improve efficiency and ease of installation. We’ll also answer any last-minute questions so you feel confident and informed about every step of the project.

3. Professional Installation

Installation day is handled by our trained, experienced installers who work quickly but meticulously to replace your windows. We protect your flooring, furniture, and walls while removing old units and installing the new ones. Our team tests every window to ensure proper function, sealing, and insulation before moving to the final step.

4. Cleanup & Final WalkthroughClean-up

We leave your San Antonio home cleaner than we found it by removing debris, shining your new windows, and returning your furniture to its place. We’ll then walk through the completed project with you, answer any questions, and ensure every detail meets your expectations. Our goal is to make this a smooth, transparent experience with minimal stress for every homeowner.

Frequently Asked Questions

How do I know when I need to replace my windows?

It’s not always obvious, but your home's windows will show signs when it’s time for replacement. Look for rising energy bills, drafty rooms, difficulty opening or closing windows, or condensation between the panes. Rotting frames, peeling paint, and fading furnishings from UV rays are also signs your windows are underperforming. New energy-efficient windows are more than a visual upgrade, they’re a smart, functional improvement that protects your home long-term.

What types of windows do you offer?

We provide a wide selection of replacement windows, including double-hung, casement, picture, bay, and custom windows, all crafted to your home’s style. If you’re looking for large viewing windows to brighten a living area, or smaller functional windows for a bathroom or hallway, we have high-quality products to suit every room and every San Antonio homeowner’s vision.

Will I really save money by upgrading my windows?

Yes! Modern energy-efficient windows are designed to reduce the strain on your HVAC system, keeping your home cooler in summer and warmer in winter. The reduction in energy bills adds up quickly. For many San Antonio homeowners, that means paying less each month while enjoying more consistent comfort and higher energy efficiency overall.

How long does window replacement typically take?

Most window replacement projects can be completed in just one to two days, depending on the size of your home and the number of windows being installed. At Green Energy of San Antonio, we custom-build each window for a precise fit, and our professional installers work efficiently to minimize disruption to your daily routine. We also clean up thoroughly after installation so your home looks exactly how it did before we started.

How much does window replacement cost?

The cost depends on several factors, including how many windows you’re replacing, the size of each opening, and the type of glass and frame selected. However, we are proud to offer affordable prices and flexible solutions without sacrificing quality. To make budgeting easier, we also offer a window financing calculator right on our site. Just choose your loan type and number of windows to get an instant idea of your project’s cost. Every free estimate includes a detailed breakdown, so there are no surprises during your home improvement project.
