"Zero stars if it were possible. Harry M came to my home and quoted me 200 dollars and cash was the only payment option he would accept. He came that Saturday and did a horrible job. He used my mower and it’s not working properly now. He didn’t have a working weed wacker and asked for my personal one. He left so many areas undone and I he did report he would come back to finish the job. This never happened; he kept saying he had me scheduled but forgot to tell me. A crew was supposed to come two Saturdays ago and this never happened. He does not respond to text messages. Most importantly, he asked to come to my house to BBQ and to date me. I have text messages to prove this. Even after I declined, he didn’t not understand no after being told several times. There’s a review on another site that doesn’t remove negative feedback and he called that person cursing them out and verbally threatening them. If he does this to me, I will immediately press charges. I’m reporting this fraud anywhere I can until I get my money back from this fraud."

"I contacted Josh at C3 for a quote to prepare and build a flat, level, 18' by 14' base on a slope framed with 3 levels of 6 x 6 timbers to retain 3 individual layers of premium quality aggregate for superior drainage and soil stability. His design was to insure the driest base environment to install a shed that will last far longer than other contractors I spoke with. I couldn't have been happier with my choice of C3. He and his crew were very professional and detailed in the work performed. Always on time and mindful of the surrounding work area and exceptionally detailed in their final cleanup of the site. I would recommend Josh and his company for this type of work and larger projects due to his commitment to excellence and customer satisfaction."
