Testimonials 

Timothy is by far the best contractor I've worked with on several remodeling projects. He is professional, reliable, creative, timely and always left the work site as clean as possible. He was also a pleasure to have in our home every day for many months. I highly recommend Alchemy Construction and its owner, Timothy Vinson.
— James Cabral
Tim Vinson and his crew were the finest I have ever used in remodeling projects over many years and many different houses.
They were always on time and left the site clean and all tools put away each day. Problems were dealt with quickly and Tim was on hand every day to supervise and always available by phone for questions.
The 1974 original dreary condo kitchen was transformed into a stunning addition to my bayfront condo in Sausalito. No shortcuts or mistakes.
I highly recommend Building Alchemy, you will not be dissatisfied or disappointed.

I have used Timothy Vinson of Building Alchemy for three major renovation projects.  In two cases, these involved working in my home while I was living there.
Timothy is extremely considerate, easy to work with, and incredibly clean and neat!  He gets along extremely well with neighbors and anyone we need to coordinate with.
He takes incredible pride in his work, and the results are of impeccable quality.  He has creative solutions to renovation challenges. I would highly recommend him for anyone who values quality and attention to detail.  I certainly intend to continue using his services when I have the opportunity.
I am happy to discuss in further detail if that would be helpful.
Regards

I have worked with Timothy Vinson and found his work and his ability to tackle any problem exceptional.  On a very difficult project he was able to translate and execute our design objectives to the fullest extent.  We plan to utilize his services in the future and highly recommend him.

To Whom it may concern....I have had the pleasure of knowing Tim Vinson for approximately 5 years both on a professional and personal level. One word comes to mind and that is Quality. Tim remodeled a very decrepit bathroom in my Marin home. The outcome was truly Magnificent. Throughout the entire project Tim always kept me completely up to date on absolutely every aspect and phase. His estimates were right on and his dedication to the work was second to none. More important to my specific needs was feeling completely comfortable leaving Tim in my home on his own for extended periods of time. He truly is an incredibly responsible and caring individual. I have done extensive work on my home and I have never experienced  anyone so organized and neat. You might say he is quite the "perfectionist".....and the work would back that statement completely. I will definitely have Tim beginning another project late this Spring and I would highly recommend him for yours without any reservation whatsoever....

Without exception, all of the work and negotiations on these projects has been very professional. Timothy takes great pride in his work, he listens to what we need and helps us figure out the best solutions within our budget. He is honest, extremely clean and a true professional. I would highly recommend him as a General Contractor.
