I have used J & M on two commercial and several residential projects over the last few years. They have always come through with exceptional service and dependability. I would recommend to anyone looking for a one stop shop for any home improvement and commercial tenant improvements. Thank you guys for always being there for us!

We have had them do work at our house on the stucco and electrical work both inside and outside our house (new wiring, new lights, new electrical boxes & switches). The entire team was great - professional, clean, polite and the work was great. I would highly recommend!

We have been using J & M Contracting for about 8 years now. The quality of their work is excellent. We have had them install a new electrical panel, drywall, paint inside and out side, stucco and texture. The entire team is great to work with. They removed siding, installed hardy cement trim, recessed lighting in the eaves.
They are clean, respectful and always on time. The quotes are always reasonable. You will not be disappointed with the results.
They listen to what we wanted and provided their professional input as well as alternate ideas for us to consider.
