"Nick and his crew were AMAZING! They were professional, polite, and clean. Nick was insightful and instantly came up with a concept design and plan. They installed a yard drainage system, created a front walkway with pavers and steps, regraded our whole property, added mulch beds, added top soil and seeded with hay for a new lawn. They worked fast and had the entire project finished in a week’s time. Highly recommend!"

"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."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"Richie and his crew were awesome! Paved my driveway and added a drain 2 years ago and today the resealed the driveway. Looks like the day they paved it. The drain was a fantastic addition and completely stopped the pooling we suffered with for the first 18 years we lived here. Great job!"
