A Renology Contractor
Hajaj Builders Group
Licensed · CSLB #1061699
In short
Renology recommends Hajaj Builders Group for electrical & solar, plumbing, HVAC, roofing, general contracting, ADU construction projects in Palo Alto.
Michael Hajaj runs this one himself, and the license explains why that works. A general building license covers the structure; the trades usually come from subcontractors. Hajaj Builders Group carries six classifications on one license: B for general building, C-10 electrical, C-36 plumbing, C-20 for heating and air, C-39 roofing, and C-61/D28 for gates and activating devices. The company also does business as CaliSun Roofing.
That matters on a job where trades have to line up. A bathroom that needs the plumbing moved, a new circuit run, and the roof patched where an old vent came out is three subcontractors and three schedules for most crews. Here it is one license and one person answering for all of it.
They cover Palo Alto, Mountain View, Los Gatos, Sunnyvale, Santa Clara, Cupertino, San Jose and Fremont, working on ADUs, roofing, solar and electrical, plumbing and full mechanical work.
Michael is on site himself. On an owner-operated crew that is the difference between a question answered today and a week of phone tag.
