Kevin and his team were great until the end of the project. During the dig they were awesome, good communication, the worksite was kept super clean considering it was a dig out, the guys on site were great too. We lived at home during the work. We had to replace the old clay drains from the city and Kevin was great about finding a plumbing and drains company for this quickly. He also recommended the HVAC company, who did our infloor heating before Tall Basements poured the slab. My only complains come at the end of the project, I expressed concern the drains for the bathroom the toilet flange and shower were very close, and was told they were standard, they are super close and now our shower has to be narrow. Tall Basements also knew we wanted to polish the concrete but the finished pour ended up pretty poor quality- there are rough sections and the edges and around the support columns and drains were not even finished. The guys even left the machine on the concrete floor leaving blade marks like helicopter blades stamped into the floor! Since the pour it’s been hard to get ahold of them with these concerns and chase them down for plumbing invoices for rebate programs. Good underpinners but a frustrating finish.
