Your Home, Our Solution


I started apprenticing for my father, Ray when I was eight, but even before that I was watching him work all the time. My grandfather established our trade specializing in carpentry and woodwork. Dad picked up new trades and expanded our skill set. I enjoy servicing the San Francisco East Bay area, and look forward to teaching skills to my daughter.

I’ll only work with the best materials available and provide a limited labor guarantee. I never compromise quality for time and give my clients realistic schedules that accommodate their lives. I strive for honest customer service, so contracts are only paid in full when the finished work is to your complete satisfaction.



This is my second experience with Shawn. I am at the point that I just make a “Shawn’s List” and make a call! He is so professional, prompt, and incredibly thorough! His prices are so reasonable also.... As a senior citizen I feel safe with him in my home and I appreciate his willingness to be creative about how to get the job done.
I cannot be more enthusiastic about Shawn’s work.

Shawn was a lifesaver when working on my Concord property, in not only the quality of his work, but just as important, he listens, and always responds to questions in a timely manner. I will recommend him to friends, and he will be my “go-to-source” for any further home repairs or remodeling

Shawn is incredibly responsive in communication, detailed in his scope of work, timely in his completion of projects and presentable on the job. He documented his work with photos and provided prompt invoicing upon his completion. Shawn is an extension of our team and knows what to do to prepare our homes for the market.

What fantastic service!! We really appreciate Shawn’s quick response to two separate repair issues. Both our broken closet door an clogged kitchen sink issues were fixed professionally and most importantly correctly. What a nice guy Shawn is. Recommend, recommend, recommend..

We hired 12 Twelve Home Improvement to remove existing kitchen sink plumbing, assist our cabinet company to install replacement bottom kitchen cabinets, and then replace the sink plumbing and install a new dishwasher. Shawn arrived 5 minutes early and ready to go to work. He did a fantastic job. He is knowledgeable, skilled and very neat. When we returned home from work, everything was complete and working perfectly. We will definitely be calling him for some other projects. After some very miserable home improvement experiences, it is a delight to find someone like Shawn! We highly recommend 12 Twelve Home Improvement!

Shawn’s a great find.
He’s personable, reliable, and accommodating.

I consulted Shawn for an estimate to replace some flooring. He was on time, thorough, and creative with ideas to save me some $$$ on the project.

Will call him again. Highly recommend.
