About Twenty9, Inc.

Twenty9, Inc. is a fantastic and amazing quality contracting company known for professional, kind, and hardworking teams. They provide a truly excellent experience, handling projects from ground-up construction and fire restoration to commercial buildouts, high-rise condominium rehabs, and design/build work, including restaurants, stores, and medical centers.

Clients consistently praise the company for being extremely responsive, reliable, and easy to speak with. The team works as if it were their own home, making noticeable progress each day. A key difference is that Twenty9 primarily uses its own skilled laborers on salary, minimizing subcontractors. This ensures consistent, high-quality work without delays from outside trades. They also have a real office with dedicated staff, making it efficient to ask questions, get updates, or handle payments.

The process is described as pleasant, seamless, and painless, with teams that are patient, informative, and empathetic. They cooperate well with building policies and clean up after themselves. Many note the valuable support from their in-house design and selection assistance. Work is completed with excellent quality that stands the test of time, often on budget and sometimes sooner than expected. Their long-term clients, some for over 14 years, and numerous referrals from friends and family highly recommend Twenty9 for any project, from a bathroom remodel to a new construction house.

We had Twenty9 gut rehab our master bathroom. My general experience with local contractors has been fair to poor. Twenty9 was the polar opposite. They are total professionals, highly organized and exceptionally communicative. Their prices were competitive and worked with us to cut expenses where we deemed it appropriate. Their workers were on time every time and did an excellent job keeping the job clean. I would confidently recommend them for ANY construction job you have big or small.

I had a great experience with Twenty 9 inc. Design Builders.
Sean (the owner) came to the property before I purchased it and gave me an estimate, and more importantly, the confidence to take on this neglected 1930s Sears catalog home. One local renovator declined the project and another told me that “for the same money, he would tear it down.”
Sean and team started my home renovation the day after I closed and worked almost every day until it was done. I wouldn’t have been able to do it without their management and skilled team. The basement was waterproofed by PermaSeal. The electric service was moved and updated, the water service updated, and kitchen and bathrooms… read full review

We were referred to Twenty9 by our amazing realtor (Kristen Esplin), who called out their professionalism, top quality work, and gold standard staffing model – which enables the team to deliver on time and without a revolving door of subcontractors.

I was immediately impressed by Twenty9's proactive approach, timely responses, and genuine attention to detail. Sean and his team truly care about your lived experience in the spaces they're helping you build, and it shows.

They offer an extensive range of services, which gave me peace of mind that our full punch list was in the best of hands. Thanks, Twenty9!
