Hughes Construction Company was hired to install 2 6ft. columns in basement to support the existing main beam, for the two columns we had to first jack hammer the floor and dig down to make room for the new footers. The footers had to be 2ft. by 2ft. by 1ft. thick, per the specifications of Buyers Protection Group. We also installed a smaller column with no footer underneath the stairs and install a pressure treated 2×10 to sister a floor joist that had been cracking.
