  • From its modest beginnings in 2006, Claymar has grown conservatively over the years into a multi million dollar sales company

  • When evaluating and determining our growth opportunities, we always analyzed two main fundamentals before making any commitments. We evaluate our finance position to be sure we maintain our foundation regarding working capital, debt to cap, and long term cash flows resulting from planned direct cost and revenues generated respectively. The second factor always taken in to serious account was our ability to employ quality people that we could count on to produce desired results here in our shop and more so out in the field. We always surveyed and canvassed the communities near where our labour is generally needed to determine our likelihood of filling our rosters adequately. 

  • We are currently comfortable with both of our fundamental gauges and in a position to continue our deliberate, conservative growth that has the backbone to operate effectively and withstand the cycles and challenges that we have known to occur over time. We are actively looking to grow our business with our existing customer base and by adding new clients as well.
