Underscore Design + Build

Bill is hands down the BEST contractor I've ever worked with. Both in terms of craftmanship, but also in terms of his work ethic and professionalism. And finding a contractor who has both these days is tough to do. He shows up when he says he will and he charges what he says he will...no surprises.

It's also amazing to see how creative Bill is when it comes to problem solving and determining the best solution for a project. His crews are incredibly efficient, professional and talented as well.

I can't recommend Bill enough and he is my go-to when it comes to anything construction related! Thank you Bill!!!

What a great experience working with Bill and his team on a complete renovation of our studio building in Healdsburg.
Bill is a problem solver and coupled with a great aesthetic and eye for quality, was able to bring our project in on budget. He was always available to answer questions and make recommendations to improve on our original plans.
We are delighted with the project and highly recommend him.

Working with Bill was an absolute pleasure—truly a breath of fresh air. He was always available to discuss ideas, offer thoughtful input, and provide quick, accurate pricing for any project changes. His professionalism, communication, and attention to detail made the entire process smooth and stress-free.

Bill’s commitment to both quality and aesthetics really stood out—he has a clear vision for the finished product and holds incredibly high standards to get there. Nothing was left unfinished or overlooked. We stayed in regular contact throughout the project, and he was always upfront and proactive about timelines and evolving needs.

Pricing was fair, and Bill handled all the county permitting and payments, which made everything even easier on our end. He also spotted a water issue early on, addressed it quickly, and likely saved us from serious trouble down the line. On top of that, he created a custom enclosure for a water pump that doubled as extra storage—smart and functional.

Highly recommend!

This company is hands-down, the most professional team of builders I've ever worked with. From the very start, my partner and I met Bill and we were very impressed as he listened to everything we wanted and he assured us it could be done. Bill's creative eye and attention to detail is like no other and that held up through the duration of our remodel. We stressed the importance of quality work and materials as well as our budget and our needs were met. The whole crew, from design to demo and construction, worked tirelessly to meet our deadline and they actually finished almost a week ahead of schedule! I can't say enough about this company. They give you their word and follow through on all of it. We're in love with our "new" home. Thank you, Underscore!

We've had the pleasure of working with Bill on two occasions, once for our ENTIRE house remodel and second for our Downtown Petaluma store facelift and we couldn't be happier with the results. From the initial consultation, it was clear that Bill possessed a rare combination of professionalism, thoughtfulness, and impeccable taste.

What truly sets Bill apart is his attention to detail. He took the time to understand our vision, offered insightful suggestions, and patiently answered all our questions. He was incredibly communicative throughout the entire process, keeping us informed of progress and addressing any concerns promptly. It was clear that Bill genuinely cared about making our vision a reality.

Beyond his professionalism, Bill has an exceptional eye for design. His suggestions elevated both projects beyond our initial expectations, and the finished product is truly stunning. Literally everyday we are in awe thinking "is this really our house". Bill has a knack for understanding what works aesthetically and functionally, and we completely trusted his judgment.

Of course, great taste and communication are only part of the equation. Bill also delivered on time and within budget. The quality of his workmanship and the folks he hires is outstanding.
Bill and his team clearly take pride in their work. They were efficient, respectful of our home (and store), and always left the job site clean and organized.

In short, we wholeheartedly recommend Underscore Modern for any construction project. The team are true professionals, Bill is a thoughtful collaborator, and a genuinely talented contractor. If you're looking for someone who can bring your vision to life with style and expertise, look no further. Bill is simply the best!
