How Your Windows Are Installed Actually Matters

When shopping for replacement windows in Houston, you’ll see plenty of ads from big-name companies like Window World and Renewal by Andersen. They promote energy efficiency, stylish designs, and strong warranties but what they don’t talk about is how your windows are actually installed.

Window World – Low Upfront Cost, Built for Volume

What they offer: Window World is known nationwide for offering replacement windows at a low cost, with fast installs. Their crews are trained to handle high volumes, moving quickly from house to house, often completing multiple jobs in a single day.

Installation method: Pocket-fit installation (measured from inside), finished with snap-on vinyl trim.

Why it’s used: It’s designed to be quick, not designed for precision. When your business depends on volume, speed matters more than detail.

Risks: Smaller glass area, lower energy efficiency, does not protect against warping in Houston heat, long-term leaks/drafts, limited options.

Best for: House flippers, short-term rental owners, or anyone whose top priority is getting the lowest upfront price regardless of long-term performance.

Renewal by Andersen – Premium Name, Same Shortcuts

What they offer: Renewal by Andersen is the retail arm of the Andersen Windows brand, offering their exclusive Fibrex® composite window product with a full-service experience and strong branding.

Installation method: Pocket-fit install, same trim-over style.

Why it’s used: They also use a pocket fit installation, measured from the inside the same basic method used by budget installers. A smaller window is inserted into the existing frame, then finished with vinyl or composite trim.

Downside: Higher cost with the same install method as lower-priced options.

Bottom Line: Their window is good, no question. But when the installation is no better than other alternatives, you’re mostly paying for the label.

Best for: Brand loyalists who want a premium feel.

🛠️ Mr. Windows – Built Around You

Method: We recommend materials and brands based on your needs. Measured from the outside, No snap trim. No shortcuts.

Benefits: Full glass area, better seal, higher energy performance.

Best for: Long-term homeowners who want peace of mind and lasting quality.

✅ Winner: Built for: Houston heat, humidity, and resale value

Note: We rarely lose on value, only on price. If we discounted our service to match every competitor, most homeowners would still choose Mr. Windows. But to deliver the level of service, product quality, and long-term support we believe in, we set our prices at a healthy margin. That’s how we stay in business and how we avoid the fate of countless window companies that cut corners, then disappear.
