Job review from in Clackamas, OR 97015 on 11/14/13

Overall Rating:

4.2  out of 5

After initially talking to Chris about the dimpled barrier that directs water to the sump pump that was installed, I thought that it would fit more closely to the ground. It sticks up in spots and does not hug the ground as I thought. I talked to Drew about this and he said it would be OK. They removed the existing vapor barrier from where the dimpled material was installed saying that it takes the place of the old visqueen.

Our Overall Service

Call Representative

Polite, courteous and professional.

Our Office Staff
Had to resubmit my VISA information as numbers were written down out of order.
Sales Process

Chris did a great job of estimating and letting us know all of our options.

Our Installation Crew

Drew and his crew did a good job on the installation. They removed an old rotted post without having to ask. A little bare earth was left revealed in a couple of spots.

The Cleanup Process

A bit of a mess was left in the street with rock which I had to sweep up.
