Job Stories From Prineville, OR
Smart Jack Interior Settlement Mcminnville, OR

    Home owners Rich and Jill of Mcminnville, OR are experiencing some sagging on the first floor of their home. The reason was that after construction, the weight of the furniture was just too much for the flooring and load beams to handle. After an inspection by Adam Lounsbury, there was no sign of mold or rot in the load beams, just simply too much weight. To restore structural integrity, a 3 Smart Jack system was installed.

    Since there is a basement to this home, 6' Smart Jacks were needed and will be installed under the first floor pads that have sunk. Smart Jack Prineville Replacements were installed at 2 of the Smart Jack locations to provide optimal strength. This project took no longer than half a day and we were finished before Rich and Jill knew it.

    After completion of this quick fix'er up, Rich and Jill are no longer bouncing in their house while walking through, and they are confident it will be like this for time to come. 

Comprehensive Settlement Issues Solves West Linn, OR

    Crawl space moisture and air conditioning issues are a huge concern for Oregon and Washington home owners. The heavy rain fall and poor initial foundation construction lead to moisture issues and eventually air quality problems. West Linn, OR home owners are all too familiar with this including Chris and Jackque M. After noticing an increase in heating bills and a damp smell throughout the first story of their home, they decided to find someone with the right skills and technology to permanently resolve their problem. TerraFirma is the "leader in the industry".

    System Design Specialist Josh Anderson of TerraFirma found two issues in their crawl space. the first was a moisture problem. Improper waterproofing had caused pools of water to build up. The moisture from the pools softened the load beams causing the floors to sag. To fix the water issue (which was the root of the problem), smart drain and drain tile was installed around the perimeter of the crawl space draining to a sump pump located at the lowest point in the crawl space. From there, water was safely discharged away from the foundation. Secondly, soft load beams and sagging floors needed to be addressed. 10 Smart Jack Prineville Replacements were installed to apply force and re-support the sagging interior home.

    Pauline and Tim can enjoy the freshness of air in their home once again. The sagging hallways are fixed and stable, and they couldn't be happier with the outcome.

Smart Jacks For Interior Settlement Issues Eugene, OR

    Ann M. of Eugene, OR has a tall crawl space area with anywhere from 3' to 7' support posts to give strength and structure to the interior portion of her foundation. After noticing some sagging while walking through her hallway, she was concerned there was a larger problem. A friend referred her to TerraFirma Foundation Systems and she quickly scheduled a free appointment to have System Design Specialist Patrick Dunn examine her foundation.

    Upon inspection through her crawl space, he noticed an issue with the support beams. THEY WERE FLOATING! Meaning the posts were connected to the house, but due to some interior soil settlement, they were not touching the ground and providing zero support to the house. A series of 12 Smart Jack Prineville Replacements were installed along the interior load beams of here home to restore structural integrity. Smart Jacks are easily adjustable to increase and decrease upward force to provide the exact amount of support needed to precisely and accurately stabilize the interior foundation. 

    Ann couldn't be happier about the stabilization. Her floors doesn't bounce or sag anymore and can be confident it will stay this way for a long time.

Retrofit and Encapsulation Provides Earthquake Protection and Efficiency

More homeowners, especially in the northwest, are performing these same two services to their houses for all the right reasons. Due to our increased awareness of earthquake potential along the San Andreas Fault Line, and our attention to energy efficiency and the "Green" movement, we install projects like these daily. 

To stabilize and reinforce a foundation for potential earthquake damage, we add a variety of bolts and brackets throughout the basement or crawlspace to reinforce from vertical and horizontal vibration that would be caused as affect of an earthquake. For this particular case 18 Prineville Earthquake Brackets, 22 Basement Bolt Anchors and 28 Crawlspace Earthquake Brackets were strategically placed through the foundation.

In tandem with being in the crawlspace, a complete encapsulation system was installed. By closing off vents, installing a proper drainage and sump pump system, adding an air dehumidifier, wall insulation and Cleanspace liner, home owners can look forward to these benefits: Cleaner breathing air through the home, ceased growth of mold and mildew spores which normally would circulate through the air, less heating bills, less cooling bills and energy efficiency throughout the entire home.

Now the Ornelas' can be confident that in the event of an earthquake, their largest investment is safe and, in the meanwhile, can reduce their carbon footprint, save money each month of energy bills and live more comfortably in their home.,

Smart Jacks Save Sagging Floor in Eagle Point, OR

The Koch's were experiencing sagging, bouncy floors in the middle of their home floor plan. After a few half attempts to shim underneath the post supports, there was constant readjusting and tweaking to make. This was a very strenuous task every month. As they searched for a new, more permanent solution, they called TerraFirma and asked about Smart Jacks. Smart Jacks are a simple but highly effective solution to support floor posts with little continual adjusting. A perfect solution for hard to enter craw spaces or hard to reach floor posts.

After Installation of a 4 Smart Jack system, the floor is now supported more permanently, in need of less "touch up" adjusting and the floor doesn't sag or bounce anymore. If desired, smart jacks are easily adjustable for more support or lift. The Koch's are now happy to have a well supported floor and are not shy to host parties or invite the family over. 

Smart Jacks Save Sagging Floor in West Linn, OR

A majority of foot traffic in any home is in the kitchen and dinning room. Over time, these support posts began to sag and the floor along with it. In West Linn, the middle of the home, right underneath the kitchen and the dinning room began to noticeably sag. 30 posts underneath the home needed to be replaced by Smart Jacks, an easy to install adjustable support post that will restore structure and strength to your once sagging floor.

Shimming is an older way of thinking for foundation post repair. Prinevilles constantly need to be re-shimmed and re-shimmed until it looks more like a stack of books rather than the supports posts to your house. Smart Jacks allow you to easily adjust and monitor the amount of sagging and the extra amount of upward force needed to keep floors from sagging and bowing. Don't think twice about sagging floors. Be happy and confident with your repairs much like these home owners.
