About Us | Signature Window

You know, I didn't start out wanting to own my own window company. In fact, I spent years working for a vinyl window manufacturing company. But there was a problem.

I started to notice that many of the windows we were installing were suffering from frame damage due to flaws in the manufacturing process and the materials being used. The problems were only made worse by lousy installs. But even worse than that… the manufacturing company was unwilling to address the issues. It became a cycle of madness. The installer would tell the client to call the manufacturer and the manufacturer would tell them to call the installer. And to add insult to injury… many times the manufacturer outright refused to honor the warranty due to "faulty installation."

Being the typical "class A" personality, I was unwilling just to leave it alone. So, I left my very lucrative career and started Signature Windows and Doors in 1999. And it was one of the best decisions I ever made.

You see, I am a firm believer in ALWAYS taking care of my customers. Do whatever it takes to make sure they are happy and that they get EXACTLY what they pay for… windows (and doors) that absolutely work as advertised.

Well, my clients loved it. And so did my employees. They love the fact that we are a company of integrity and that we stand behind our products—and installations—100%. It's just one of the reasons we have employees that have been with our company since the day we opened.

Then in 2001, Randy Lucas joined the team. Together he and I decided to truly focus our efforts on building the best window and door company in Seattle. This singular focus enabled us to receive the Angie's List Super Service award for eight years in a row!

But still, something was missing. We started to see quality issues with some of our window manufactures and we knew that we needed to make a change. You see, Pacific Northwest weather is particularly brutal to windows. We get freezing rain and blistering heat. This causes some serious expansion and contraction of the window frames. And many windows simply can handle those stresses.

That's when we brought Greg Johnson onboard. And that is when—together—we decided that from this point forward (2015) we would only sell and install the INFINITY Brand of Windows from the Marvin Window and Door company.

Why? Because I firmly believe and our company is founded on the very same principal I used when I first opened for business: ALWAYS take care of your customer. Do whatever it takes to make sure they are happy and that they get EXACTLY what they pay for.

That is the Signature Window and Door Company difference.

I look forward to meeting you.
