Why Homeowners Trust AWD

Since 1996, Authentic Window Design has built its reputation on offering the right products, delivering superior craftsmanship, and creating results that stand the test of time. From the beginning, our success has grown through word of mouth, reputation and our commitment to quality and service.

Every home is unique, and so is every project. That’s why we take the time to understand your style, design goals, and budget to recommend the perfect window and door solution. Whether you’re building new, remodeling, or replacing old windows and doors, our friendly, knowledgeable team will guide you every step of the way. Plus, we stand behind our work with a Lifetime Installation Warranty, giving you complete peace of mind.

The AWD Experience
- The Lavitt Way

Exceptional results begin with a thoughtful process and foundation.  AWD embraces the basic 26 fundamentals that differentiates our unique culture. 

1. Personal Consultation

Your dedicated project manager will visit your home, take meticulous measurements, and guide you through styles, materials, and finishes.

2. Tailored Proposal

We’ll present a detailed plan designed to align beautifully with your home and lifestyle.

3. Flawless Installation

Our expert craftsmen handle every detail, ensuring a perfect fit and seamless finish.

Why Custom Windows Matter

At AWD, we believe your windows should fit your home—not the other way around. That’s why we offer custom-crafted windows designed to fit perfectly into your existing openings.

A snug fit means fewer drafts, better energy efficiency, and no worries about water leaks that can damage your home over time. Plus, custom windows look and perform better for years to come.

Installers You Can Trust

Even the best windows and doors won’t perform well if they’re not installed correctly. That’s why our team is Marvin-authorized and undergoes extensive training every year—more than 800 hours combined! We’re fully licensed, insured, and EPA Lead-Safe certified. And because we’re so confident in our work, every installation comes with our Lifetime Installation Warranty.

Built on Relationships

Authentic Window Design has grown through the recommendations of delighted clients. Many return to us for additional projects or refer us to friends and family—proof of the trust we’ve earned over decades.

Our care, discretion, and attention to detail mean you can expect a smooth, satisfying experience from beginning to end.
