This is SMB15, a rapid-fire interview series featuring small business owners, investors and service providers. We dig into different industries, business models, and SMB topics. Hosted by Will Fry, founder of Mainshares.
From a five-star review on his very first job to scaling toward $600K in revenue, Will Barrett’s journey with Will Do It Windows shows what happens when you combine grit with speed of execution. He shares the scrappy beginnings, the early hires, and the lessons that helped him turn a simple service into a serious business.
In this episode, we dive into starting lean, finding the right marketing mix, and building culture in the trades. Will explains how he used door knocking, Google reviews, and Meta ads to drive growth, and why “just doing it” is the only real way to learn.
Some takeaways:
Start small, sell first. Don’t waste thousands on equipment until you actually have paying customers. Focus on landing jobs, then invest in tools that help you move faster.
Hire early to scale. Will realized within a month that he couldn’t sell, clean, and manage everything at once. Bringing on a technician freed him up to focus on growth.
Culture drives consistency. Reliability, communication, and shared vision are what keep his technicians motivated. Every five-star review reinforces both accountability and pride in the work.
Marketing doesn’t have to be complicated. Meta ads, steady Google reviews, and even simple yard signs have been enough to build consistent inbound demand.
Execution beats perfection. Will doesn’t wait for the “right time”, he acts on ideas quickly, learns from mistakes, and adjusts. This mindset helped him grow fast without overthinking.
Community matters. Small business ownership isn’t just about revenue; it’s about relationships. Running into clients at the grocery store or events makes the work more personal and rewarding.
