    Bio-One of Oceanside was a life-saver for me! I had a situation where their help was needed quickly. They met me the same day and had the job started the next day and completed quicker than I could have hoped. Plus, they did an amazing job! I couldn't believe my eyes from the before and after! It was like night and and day the improvement. Armand and Michelle, the owners of the company are also so very kind and courteous and easy to work with. They communicate well and are professional yet personal and care to make sure they do excellent work! Calling Bio-One was the best decision I made for the situation at hand. I can't recommend them enough!

    "I met Armand & Michelle at the Strawberry Festival- Very nice folks. They explained there services well and came in for a quote as soon as i was ready - had their technicians out within days of me getting back to them. I had a bad experience with another company - Bio-One restored my faith! Paulino & Jesus were AWESOME! Quick, efficient, professional, non judgmental and so nice! I had a lot of stuff to get rid of - they did a great job! THANK YOU!"
