When it comes to upgrading your home, few decisions are as impactful as choosing the right windows and doors. They shape the look of your house, affect your energy bills, and even determine how comfortable and secure you feel at home.

At Lion Windows & Doors, we believe buying windows and doors should feel exciting, not overwhelming. That’s why we created this guide—to give you the knowledge you need to make confident decisions and to show you how we’ll support you at every step.

1. Why Windows & Doors Matter More Than You Think

Your windows and doors aren’t just functional. They play a key role in:

Energy efficiency – cutting heating and cooling costs.
Curb appeal & resale value – first impressions matter.
Comfort & safety – natural light, sound reduction, and security.
Lifestyle – seamless indoor-outdoor living with large sliders or bifolds.

Investing in quality products is one of the smartest upgrades you can make for your home.

2. Step One: Define Your Priorities

Every project is unique, but we always start by asking homeowners:

What’s your top priority? Energy savings, aesthetics, durability, or all three?
What’s your budget range? A ballpark budget helps us match you with the right products.
What’s your home’s style? Modern, traditional, transitional—we’ll align products with your design vision.
How long do you plan to stay? Short-term ROI vs. long-term investment can guide your choices.

3. Window & Door Materials Explained

Here’s a quick look at the most common frame options:

Vinyl (e.g., Milgard Trinsic V300): Affordable, efficient, low-maintenance.
Fiberglass (Milgard Ultra C650, Pella Impervia): Durable, sleek, excellent for larger openings.
Wood & Wood-Clad (Pella Architect, Simpson): Warm, timeless, customizable.
Aluminum (Fleetwood, LaCantina): Ultra-modern, perfect for big glass doors and slim sightlines.

4. Retrofit vs. New Construction Installation

Choosing the right installation method is just as important as choosing the product:

Retrofit (Z-Bar): Fits into existing frames, minimal disruption, cost-effective.
New Construction (Nail Fin): Best for remodels or new builds, maximizes glass area and ensures top-tier waterproofing.

👉 Our experts will guide you after an on-site size verification so you know exactly which method is best for your home.

5. Warranties That Build Trust

When you invest in new windows and doors, peace of mind is just as important as performance. That’s why we partner with leading manufacturers—Milgard, Pella, LaCantina, and Fleetwood—who all provide strong warranties on their products. These warranties typically cover frames, glass, and hardware, ensuring long-term protection for your investment.

On top of that, Lion Windows & Doors provides our own installation warranty, so you’re covered both for the product and the workmanship. In other words, you’ll never be left chasing down a manufacturer or installer—we stand behind everything we sell and install.
