I hired mark Knowles on thumbtack to fix a jarred lazy Susan corner cabinet. The cabinets are from the 70s, but still in great shape, except that one mechanism for that one cabinet. Parts were hard to find, but Mark went out of his way to find the right part, at a very reasonable price. He, in turn, supported a self employed, small business vendor. When he received the part, he called me immediately to set an appointment for the install. Mark was on time as promised, was personable, and very experienced with the repair that was done in a matter of minutes. I was thrilled to be able to use the cabinet again. Thank you, Mark. I would highly recommend you to anyone and hire you again for future needs.
