Horrible customer service! Would not recommend dealing with Marissa! I originally contacted this…read morecompany to get an initial consultation and quote on my backyard patio interlock project. I spoke with Marissa on the phone and we agreed on a day/time for her to provide the initial consult (which would be 2 days later). 20 mins past the scheduled appointment time and she had not yet arrived so I gave her a call to check if she was still on her way. When she picked up the phone, I gave her my name and asked if she was able to make our scheduled appointment time. It was at point that she told me she had to cancel on me (no apologies, no offer to reschedule). It's only after I asked her if she was planning on informing me that she was not going to showing up for the appointment that she gave a reluctant apology and said she had too many projects and appointments already scheduled to accommodate ours. What kind of customer service is that?! If she had too many appointments and projects on the go, then she should have told me this during our first phone call. A professional organization would not waste their customers' time like this and would have the common courtesy to simply let their customers know if they were not able to follow through with a scheduled appointment.

This company is GREATLY overrated…read more Our project involved a large backyard space transformation and included installation of a fiberglass pool, sport court and stone patio. The cost of the project was well above 200K. Throughout, our project was marred by delays, setbacks, mistakes, and frustrations in dealing with a company that refuses to take accountability and has very little interest in striving for customer satisfaction. In the end the experience was wholly unpleasant and I would not recommend this company. I waited a year to post this review in a fair effort to have the owner address multiple deficiencies (for details see Homestars review). After being ignored and receiving more gaslighting comments, I finally felt that it was important for other potential customers to hear of a different experience with this company. In my opinion, a company's true nature is shown by how they address mistakes and strive for customer satisfaction. No one is perfect but to continually ignore, deflect and string along a paying customer like ME did to us is completely unacceptable. By the way, the latest "glowing" review prior to mine is from the wife of the owner of the company!
