The Founding Story of Lake Washington Windows and Doors

Meet Adrian Au

Founder of Lake Washington Windows & Doors

Adrian Au founded Lake Washington Windows and Doors in 2008 after working in the industry for 19 years. Learning the ins and outs of one of the top window manufacturing companies in America and helping window and door companies across the country, he learned what made or broke a customer’s experience. He took this knowledge and applied a new standard of customer care and window installation to his company, Lake Washington Windows and Doors.

Adrian’s Early Career Working at Milgard

Adrian started in the window and doors industry in 1990 while he attended the University of Washington Business School. He started working as a Service Technician at Milgard during the summers. Once he started, Milgard was so impressed by his reliability and hard work, that they promoted him to sales after he graduated college. This would entail Adrian representing Milgard and helping “dealer” companies sell Milgard products.

For the next 18 years, Adrian would travel across the country working with dealers across America and soon be promoted to help launch Milgard’s East Coast division. Never planning to make a career in the windows and doors industry after college, he became pleasantly surprised at the community he developed at Milgard and the wealth of knowledge he gained about window manufacturing.

Ever since he was a young boy, Adrian had always been good with his hands – tinkering with tools and building things. He had always been fascinated with architecture, home design, and construction. So, when he stumbled into this industry, it seemed like a natural fit. This interest combined with his entrepreneurial spirit motivated him to eventually start Lake Washington Windows and Doors.

Starting Lake Washington Windows & Doors

The trigger to start his own company wasn’t easy. Adrian had worked for Milgard for 18 years before leaping into entrepreneurship. During his time working with different window and door companies, he realized there was an opportunity to deliver more value if he were to start his own company. He learned that quality, communication, and customer care were the most important aspects of a person’s window and door buying experience, and he didn’t want that to stop at the product.

  • Elevate homeowner-contractor interactions: Aim for trustworthiness, honesty, accountability, and communication.
  • Ensure transparency and respect: Promote clear communication and respect for both the homeowner and their home.
  • Revolutionize the home remodeling process: Make renovations non-invasive, comfortable, and seamless.
  • Commitment to cleanliness: Ensure homes are left cleaner than before the project began.

Becoming #1 Milgard Dealer in Western Washington

In 2008, Adrian founded Lake Washington Windows and Doors to not only create a better path for himself but to serve his local community. He wanted to focus his primary product offering on Milgard products and continue his relationship with Milgard today. Now, he is the owner of the #1 replacement Milgard dealer in Western Washington. 

After starting the company himself, he quickly started to build his all-star team. Adrian’s first hire was his long-time friend, Ryan Roberts, who now runs the commercial division. 

10-Year Leak Armor Guarantee is Born

In 2015, Adrian and his team developed a unique installation process to add more value and longevity to customers’ windows and doors. They created the exclusive Leak Armor Guarantee, which was born from thousands of installations and years of experience.


Leak Armor Benefits

  • Increased resistance against leaks and water damage
  • Enhanced windowsill protection that blocks out moisture and prevents wood rot
  • Additional buffering against the wind to reduce drafts and low room temperatures
  • Improved sound control, keeping more outside noise out of the home
  • Increased energy efficiency, saving you money on heating and cooling costs

Acquisition of Marine View Windows

In 2020, Lake Washington Windows and Doors had an opportunity to expand and grow by acquiring Marine View Windows and Doors. 

With a second showroom in the south Puget Sound area, the company’s service area expanded dramatically to include Tacoma, Puyallup, Lakewood, Gig Harbor, Bremerton, Silverdale, Poulsbo, and more. 

The combined operational resources allows Lake Washington Windows and Doors to provide better service with increased quality and efficiency.
