Job Stories From West Linn, OR
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 Post 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.

Large Foundation Concrete Cracks Cured with FlexiSpan West Linn, OR

    Generally caused by concrete shrinkage, large cracks in concrete foundations can form. Cracks can continue to grow by expansion and shrinkage of the cement over time and lead to bigger problems. These weak points become the entry path for unwanted water, unconditioned air and sometimes insects and critters. The permanent solution not only is an air-tight seal that prevents water, unconditioned air and critters from entering the home, but is also flexible to expand and shrink with the cement without sacrificing the air-tight seal. The answer, FlexiSpan.

    Local West Linn, OR resident Brian L sealed a large concrete crack with FlexiSpan and is confident he has the best solution on the market to repair his foundation crack and will continue to be effective long term.

    

Green Solution for Crawl Space

There are a variety of products you can install throughout the house to turn your home into an energy friendly, money saving, health providing system. Insulating windows, using proper light bulbs and unplugging appliances when not being used are all great options; However, there is a solution that trumps all those results combined. By encapsulating your crawl space, you can turn your energy and money glutton home into an efficient, environmental system.

Frances H. was experiencing standing water, musky odors and high energy bills year round before transforming his crawl space. As we all now know, venting your crawl space only allows for good air to leave your home and bad air to enter. This air brings in moisture (among other things), elevates temperature and humidity levels causing the development of mold. The result is elevated energy usage, higher average energy bills and air born mold spores floating throughout the house. By encapsulating his crawlspace with Cleanspace liner, sealing off vents, installing a dehumidifying unit and proper water drainage and removal, Frances has seen a complete turn around in home efficiency.

Like Frances, homeowners seek the best options to improve their home living quality and increase the value of their investment. By encapsulating his crawl space, Frances achieved all of this.

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. Posts 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.

Custom Drainage System in West Linn, OR

This homeowner is getting water in her crawlspace. It has been a problem they have been dealing with for a long time. After trying a variety of waterproofing units and numerous french drain systems none have provided a lasting solution. the crawl space is about three feet tall and will be in need of a newer more powerful sump pump along with added drainage line to remove water permanently and dispose of away from the home and out of danger.

In this particular case there was no indication of high humidity levels, just high water levels, which worried the home owner about possible settlement issues. Upon inspection by Chris Kelly, a simple change was made. The current sump pump was not strong enough, so we upgraded the unit to a Triple Safe, the strongest most effective sump pump on the market today, and the discharge lines were not effective placed to completely remove the water away from the home foundation. So the fix was simple, and all it took was some critical thinking, a great understanding of drainage systems and good analysis.

Water issue under house
S Wisteria Road in West Linn
We recently bought a home that was built (or moved to its current location) in 1948. During the home inspection, the inspector raised some concerns about the foundation. We had a structural engineer look at it, and he deemed it "adequate". Still, we have nagging worries that it's going to be a problem. I'd love to have somebody come out and take a look at so they can tell us what it would cost to repair (if it needs repairs). Additional information: Main Area of Concern: Foundation

A plumber recently alerted us that our foundation likely needs repair and provided us with a photo that showed a large crack and a small puddle of water. The only issue we have previously noticed was the sticking of the front door, which is near crack. We would like a quote for the cost to stabilize the foundation. I have begun a landscaping project that will more effectively move water away from the house and am also arranging for new gutters.
