We were asked to replace a stair and handrail system on the back porch of this house. The old wood stair unit was angled down causing an unsafe condition and only had a handrail on one side. The customer was a senior and was concerned about safety when using the stairs. We removed the old stair unit, installed a concrete pad for the new stair unit to keep it stable, and installed a new custom built pressure treated stair unit. The handrails on both sides make it much safer to go up and down the stairs. There is an concrete porch under the wood stairs. The new stairs were built over the concrete porch. There was no reason to remove the concrete porch as it was still viable.
