Why Adrian Au
Stands Out

Adrian Au is the Founder and CEO of Lake Washington Windows & Doors and Co-Founder of WindowEdge.ai. His career in windows and doors began in 1990 while attending the University of Washington, when he joined Milgard as a summer service technician. After graduating, he moved into sales and spent approximately 18 years working with window and door dealers throughout the country, eventually helping launch Milgard’s East Coast division. In 2008, Adrian left the manufacturer side of the industry to create Lake Washington Windows & Doors around a different model of home improvement: consultative selling, transparent communication, disciplined installation, and what he describes as “Nordstrom” level service. He later worked with his installation team to develop the proprietary Leak Armor moisture-management system for Pacific Northwest homes. Today, Adrian leads a 65+ employee window and door organization while also helping build WindowEdge.ai, bringing his decades of contractor, sales, operations, and customer-experience knowledge into the next generation of AI-powered home improvement systems.

Where Adrian Has a
Point of View

Building a home improvement company around service rather than sales pressure Servant leadership in home improvement How defined sales processes create consistency Scaling contractors with SOPs, KPIs, and accountability Why installation quality matters as much as product quality The evolution from technician to salesperson to CEO How manufacturers and contractors can better understand each other Creating a high-performance sales culture without losing humility What AI will change about the home improvement customer journey How contractors can capture and respond to demand 24/7
The best product in the world becomes a bad investment when it is installed poorly.
Most home improvement companies do not need more pressure in the sales process. They need more clarity, consistency, and trust.
Customer service should not begin after the contract is signed. It should shape every interaction before the homeowner ever buys.
A sales culture cannot outperform the standards and accountability of its leadership.
You cannot scale a contractor on tribal knowledge. Processes, KPIs, and expectations have to be visible and repeatable.
AI will not fix a broken operating system. It will expose it faster.
The companies that win with AI will not simply add tools. They will redesign how demand, customer context, and follow-up move through the business.
Humility and high performance are not opposites. The strongest teams need both.
