After dedicating nearly 16 years to building premium remodels and additions for others, he chose to establish his own business. He has served as a field supervisor for Carey Construction and as a foreman for energy-efficient renovations at Fresno's civic centers, believing that the best part of completing a job on time is the people you work alongside. James likes to spend his free time with family, hiking, and volunteering from time to time. Serving others has led him to friendships, satisfaction, and success. As a third-generation contractor, James Yancey brings a wealth of experience. After a few years of finding his niche, he settled into handyman services. “I grew up maintaining rentals for the family business and have 20 years of experience at the age of 36. Working in construction provides me with daily variety and the chance to get things done right. I genuinely love this industry!”

Recommended Customer Reviews
James and the team at Diablo Valley are very professional. They came out visited the house to provide a free quote on a number home repair items from fixing a broken window screen, repairing a fence gate door to open much easier, to installing new light fixture. We set up a date and time and they showed up promptly. They quickly finished all the work in a just few hours. No messing around. Excellent quality work too. Definitely, recommend them to anyone looking for home repair help.
John O.We really enjoyed having the Diablo Valley Handyman service in our home to do a dozen or so small projects done quickly and effectively. Polite, efficient, and effective.
Great customer service! James and his team (Joe, Billy & Patrick) are wonderful to work with, and they are very professional. They are and truly exemplify what Great Customer Service is! I now have a someone to contact for projects that come up in the future.
Brian G.Diablo Valley Handyman services actually came out and did good work on my house! That alone is a hard thing to find in the Bay Area these days. They worked with me on the level of work that I wanted done and made sure that I was fully aware of my options. I'm really impressed by them and hope to work with them more in the future!
Larry K.I would highly recommend Diablo Valley Handyman for any home improvement project. James was quick to respond to our kitchen project during the busy holiday season and Devon followed up right away to assess the work and provided a fair quote for a difficult job. Carlos was on site to do the work and completed the job in a timely manner. This team is punctual, professional, courteous, skilled and thorough and we will be calling them again for other home-improvement projects. Thank you James, Devon and Carlos for your great work and awesome customer service!
James and his company deserve to be at the top of the list. He went out of his way to check on my concern about a cracked beam in my garage. He got me 3 estimates and his guy completed the work in one day and left the garage a little cleaner than I had left it. Thank you so much!
Devon + Billy installed a track light in my kitchen with a vaulted ceiling along with a few other items that i needed troubleshooting. The mount was a little tricky but they executed flawlessly and even matched the stain of the mounting blocks to my rafters perfectly. They also fixed the other items with a positive problem-solving attitude.
We began working with James and his crew early in 2015. Our first project was very minor, and James handled it himself. From that first meeting, we've called on James for all of our upkeep and improvement needs which included some small projects and some very large and difficult projects; all of which have been accomplished in superior fashion. James has a wonderful group of professionals, and we've met all of them: Billy, Chris, Patrick, Devon, Joe, and they've all helped us many times. We always call James first when we have a problem or idea we want to explore, and he's always here for us.
This group is the very best, and their approach to working with clients is sensitive, creative, thorough, adaptable, and, most importantly, honest. We sincerely recommend them; they are superb!
Missy S.I cannot say enough good things about these guys. I only wish I had found and contacted them 2 months ago when I started numerous repairs on my rental property.
I met Devin and James for an estimate to patch and level a nasty concrete laundry room floor and for troubleshooting a couple electrical outlets that I suspected didn't work (one being a 220 outlet). Both were very nice and informative. Tho I wasn't expecting to receive the quote until the next day, to my surprise I had it a few hours after meeting. When I will explained I had to leave town in less than a week and asked when the work could be done, I was presently surprised to hear James could have Joe at my house the next morning.
Upon meeting Joe I realized this company consists of a bunch of nice knowledgeable informative guys and I was happy to be doing business with them. Unfortunately, I have come across a few situations where I felt disappointed with hired repairmen for numerous reasons whether it's their work or fact I feel taken advantage of. Not this time!! Joe was very kind and showed me what he found (which was a very scary burnt electrical box with melted wires) explained what was wrong with it, how it should have been done and then did what he needed to rewire my outlets correctly.
Today Joe and Patrick came to do the floor. Again, I could not have been happier with the guys and their work. Joe made suggestions for my floor care and covering which I truly appreciated. He took the time to ask about the property and if there was anything else that I might need help with now or in the future, to give them a call. I have a feeling had I called these guys 8 weeks ago, my rental repairs would have been completed over a month ago. I am just happy to know about them now!
Thank you all for all your time and work.
Joe, thank you for going above and beyond! Truly appreciated!!
Andrea R.James sent two awesome gentlemen to mount/install my TV above my fireplace. They did an incredible job. They were extremely professional and knowledgeable. They cleaned up afterwards and took all of the large boxes out to the recycling area for me. Thank you guys!!
I will definitely recommend James and his Team to everyone I know in the Contra Costa/Alameda County Area.
