Tool Tech Construction Supply 4647 Las Positas Road, Livermore, CA 94551

"These guys are professionals, period. I have purchased tools, air compressors & fasteners several times as well as having tools serviced over the years. Their knowledgeable staff always gives me the information I need to get the right tool for the job. If you are a professional builder or in the trades, this is your new tool store, you can thank me later."

"Very good customer service. Tool venders every Thursday. Dealer to every major tool manufacturer. Milwaukee, Dewalt, Makita, Bosch, Channellock, Gearwrench, Jet, Fein, Diablo, Wilton, Metabo and many more. Some old finds too! Definitely a lot of stuff that HD doesn’t have!"

"very friendly and knowledgeable staff. I loved their vintage power tool display. The only issue is they are only open during the week. Great assortment of Power Tools in addition to fasteners."

"Called about an out-of-warranty Makita reciprocating saw that jammed. Christiansen is an authorized Makita dealer and they told me they repair hundreds of tools a month at their shop in Livermore, as well as selling replacement tools. They were quite helpful over the phone and gave me multiple options for repair or replacement of my broken tool. I felt that they went out of their way to be helpful ... hence the 5 star rating."
