Job Stories From Gresham, OR
Self Installed Sump Pump to Water Guard; Gresham, OR

The customer us when his sump pump started to flood his basement due to sediment buildup. The discharge line they had installed, cracked leaving them with a bigger mess than they ever imagined. 

We came and dried out the basement. Taking out the old sump pump and discharge line. So that we could install our system without any hiccups. Francisco and his crew dug a trench line along the parameter of the basement for the WaterGuard

To replace the old sump pump they installed the SuperSump pump. With a 1 1/2 inch discharge line. Ensuring that when they laid the concrete down no water would intrude the space again. Or cause any more damage, leaving the customer overjoyed with knowing they have storage space once again.

Vicinity of NE Country Club Ave in Gresham
Hello, About two years ago, your team installed a new sump pump on the home we closed on. We are about to sell the home now and during an inspection there was evidence of water noted on top of the vapor barrier and they buyer is requesting the sump pump be repaired. Our inspection period ends this Friday, so I was hoping someone could come out and look at it and see if this is covered under warranty still as it is fairly new. Thank you so much in advance.
