Job Stories From Cottage Grove, OR
Cottage Grove, OR Home Protected by Super Sump Pump

    Cottage Grove, OR resident Judy R knew that she needed to have her crawlspace looked at. There was a high level of moisture starting to come in. She started asking around to friends about who could help her. They recommended that she call TerraFirma Foundation Systems.

    Just days after contacting the office they sent out their sales representative Casey Moore. He did a through inspection of the crawlspace to determine what would be the best fix would be. Casey suggested that they install Smart Pipe and a Smart Sump Pump in the crawlspace. The Smart Pipe is perfect for the crawlspace and is designed to run along the perimeter to direct water to the Smart Sump Pump, which will pump any water that gets into the crawlspace out of it.

    Judy now has peace of mind knowing that her crawlspace is protected from further water damage.  

Foundation Settlement in Cottage Grove, OR

    Ellis and Melba E of Cottage Grove, OR noticed a large crack in their wall that kept getting bigger.  Also one of the doors was hard to open and close. They started looking through the phone book for someone to call. They came across a listing for TerraFirma Foundation Systems and decided that they would set an appointment.

    A couple weeks later they sent out sales rep Todd Black. After doing a thorough inspection of the property he suggested that they install Push Piers in the foundation. These piers can be installed inside or outside of the foundation walls and will not only stop settlement but can lift the foundation back to its original position. This will close any cracks and improve the function of the doors.

    Now that their foundation is protected by the Push Piers, they no longer have problems with cracks and doors sticking.
