I just had a sump system put in my home 3 weeks ago. They dug up the concrete the length of the house and 13 feet to the front. They dug a 3 ft deep hole for the sump. In the longer channels they used corragated pipe ontop of crushed stone, then they cemented over the top. They of course ran the PVC from the pump up the wall and outside. The whole job took them 5 1/2 hours and they charged me $3750.00. The company had 4 guys working, maybe $500.00 in material, i figured with labor and parts, the Company itself made roughly $580.00 and Hr. That's good money and money well spent here. They also guarantee it 100%. New carpet is covered.
