Our Clients Say It Best

Our reputation is an extension of the satisfaction we bring our clients. Read what our clients have to say.

We were so lucky to find J.O. Contracting LLC. We hired them to do a bathroom in our basement (where no bathroom existed). Jaro came with his crew and advised us on what would work best for us. We were not disappointed. Jaro and his crew were very professional, cleaned up after themselves every day and were very time efficient. We had a brand new bathroom in less than 3 months. I highly recommend J.O. Contracting LLC. - Julie G, Linden NJ.

Jaro and his team did a great job installing a house fan at our rental property. It works great and has been a great help reducing the heat in our attic. - Eric

Very happy with Jaro and his crew. The floors came out great, the railings to our stairs, the fix of our gutters all done well and quickly. I really like how he and his team work. - Nanie
