Contactor does sloppy work, will not return to correct poor workmanship issues. I had a Techoblock patio installed at my home. Contractor would not return calls or return to site to repair patio light that they installed and was not working, tops of pillars were installed incorrectly, not enough sand was installed in joints and many other poor workmanship issues too numerous to name. Contractor also violated the terms and provisions of the contract.
