I would recommend Groundworks for their professionalism and customer service. The company is customer oriented from initially making appointment for my free estimate to keeping in touch until arrival. I would especially like to give special recognition to my inspector Matt H. for his exemplary customer service and professionalism. Groundworks is very fortunate to have inspectors like Matt H. in their employ.

Alright so let me begin by saying my house is like a hundred years old and the basement is also very large and on a hill. So I had both waterproofing and the pentec floors put in. Mark and his team were super flexible and were always on time and on schedule. Ryans team was also super flexible and were able to address several issues that showed up during and after the waterproofing work.
So complications and surprises did pop up along the way and additional water proofing did need to be done and in total that added an extra 9k to the bid(s). So it was a little painful to eat the extra cost but seeing the work that was done / had to be done I can say that I feel that the additional cost was fair. So i do want to give Ryans team and Mark especially some kudos because the work they did is an extremely hard job (especially with part of the basement being sunken space) and they really put in extra effort to make minimize any impact the work would have on my family and I appreciate all of the hardwork! So I would say if your looking to have the work done right and the floors to look amazing I would give Mark and Ryan a call!

I was happy with the work Groundworks did at our home. It was done professionally and looks great! There was a slight problem with scheduling due to weather conditions but in the end they made it work.
