Job Stories From Longview, WA
Settling Home Addition Longview, WA

    For Longview, WA home owner Betty H., her addition in 1962 is causing her problems 50 years later. The addition is an 8' by 30' room and has settled almost 6" in the worst spots. This is significant and is a health hazard. Not just because of the unevenness to the house, but because of the structural integrity of the foundation has also been compromised allowing humid air, moisture and critters under the home. It is an unsafe and unhealthy environment. she saw a tv ad showing how TerraFirma could permanently stabilize and lift her foundation, so she called immediately to schedule a free inspection.

    As inspected by System Design Specialist Ryan Lahley, a 10 push pier and 4 Smart Jack system was designed to permanently stabilize Betty's add on foundation. 10 push piers were installed around the perimeter of the foundation. Once driven to proper depth and achieved adequate capacity, the weight of the home was fully resting on the piers which were anchored in sufficient load bearing soil.

    As for the interior settlement portions of her home, Smart jacks were installed under the load beams that had also began to sink. By re-supporting the load beams we eliminated the sagging and that "bounce" when walking through the room.

    With one system we were able to permanently stabilize Betty's foundation and re-support her interior settlement issues. She can be sure that her house won't be settling anymore.

Multi-Room Cleanspace Encapsulation Longview, WA

    Home owner Mike C. in Longview, Washington has been continuously adding on to his home for the past few years. At first for pleasure, a new media room, or home office; However, as his family grew he wanted to make sure that his add on rooms were up to code as far as health, insulation, cost effectivity and personal comfort. After seeing a TerraFirma ad on TV, he knew instantly he found a professional company that could help him with his home goals. Specifically for under the home in the crawl space.

    Kevin Miller, a System Design Specialist at TerraFirma, inspected Mike's crawl space and designed a perfect solution for three separate crawl space sections of his property. By completely encapsulating the area, Mike was able to achieve all of his home goals. After condition the crawl space environment with Cleanspace and a dehumidifier, Mike house now circulates healthier (mold free) air. By installing SilverGlo wall insulation around the interior perimeter, not only was Mike able to keep his home warmer but in doing so, achieved higher comfortability and saves money on heating bills.

    It was a simple 2 day project which required virtually zero destruction to the home. Mike now has an efficiently running home that him and his family can be comfortable in any day of the week.

Cleanspace Cleans Up Dirty Crawlspace in Carson, Wa

In the hills of washington, proper home drainage systems are a must have. For homes that don't, you might find yourself in a similar situation to the Crooks. Their hill-top home was not originally waterproofed and no sufficient drainage system was in place causing their crawl space to collect water. These elevated levels of water caused humidity issues rotting away at the wood house supports. A complete crawl space encapsulation is the best way to remedy this issue.

The Crooks complete crawl space system comprised of a few products, all playing a specific role in the system. Cleanspace isolates the wet and cold ground from the crawl space air, SilverGlo wall insulation reflects warm air back into the house, a sump pump and proper drainage matting allows for collection of excess water and removal, and lastly a dehumidifier the condition and circulate the air. 

To the delight of the Crooks, this home is now an energy efficient and comfortable home to live in once again. By successfully encapsulating their crawl space, they can be sure their home will retain its value for many years to come and they can enjoy it in the meantime. 

Smart Jacks and Cleanspace Beautify Home in Vancouver, WA

The Northwest is a beautiful place to live. The landscape is so diverse and green because of the year round heavy rain fall. Although these conditions are why our terrain is so beautiful, it can be harmful to your home and specifically the foundation. A Vancouver, Washington home has suffered from years of moisture problems causing the humidity and mold levels to rise, and the floors to sag due to rotting supports. To restore the value of the home, the foundation will need to be stabilized and the crawl space environment conditioned. 

To achieve the first goal, Smart Jack posts were installed and secured to the support beams under the house. These easy to install and adjust steel supports will not only stabilize the foundation from continuing to sag, but will also raise the floor up to eliminate the "bounce" in your step. To achieve the second goal of conditioning the crawl space environment a combination of products were installed; Cleanspace liner isolates the air from the Earth, SilverGlo wall insulation regulates air temperature reflecting warm air back into the home, insulating and heating at the same time, and a sump pump and dehumidifier to regulate the moisture and humidity levels.

the Rauch's are very happy with their new crawl space, all the while improving the comfortability for their family and increasing energy efficiency. A win-win all the way around.

Crawlspace Conditioning to Floor Restoration in Battle Ground, WA

Cracks are forming in the walls above a widows and in the corner on the second floor. More cracks appear in the bathroom under the stairs on the first floor. The interior floors are sagging and have a bounce to them when you walk across. Does it sound like I'm describing your house? Many people who suffer from crawl space issues see the aftermath in all sorts of places throughout the home. 

The Hixson's crawl space was wet and humid causing a rotting in the support beams. Because of the rotting support beams, the interior floors began to sag pulling away from the interior walls. You guessed it, now the interior walls and, in some areas around windows, show signs of cracking. The Hixon's had Smart Jacks installed on the interior support beams to stabilize the sagging floor raising them and re-supporting the walls. The Hixon's have only fixed one part of the problem though. After conditioning the crawl space with Cleanspace liner, SilverGlo wall insulation and a dehumidifying unit, the Hixson's can be sure that their sagging floors and cracking wall problems are finished.

Water Seepage into Longview, WA

    Longview, WA native Tony B was having a problem with water leaking into his basement. He was worried that it would create major problems in the future so he started looking for a company that could help him. While looking through the internet he came across an ad for TerraFirma Foundation Systems and decided this was the company he needed to call.

    A few days after speaking to the office they sent out Deryl George to inspect the basement. He recommended a few products. The first was the CleanSpace wall system which is a vapor barrier that is attached to the walls of the basement and will prevent water and moisture from coming through into the basement. This wall system would also drain that water into the WaterGuard interior drainage channel which is installed along the perimeter of the basement to catch incoming water seepage and direct it towards a sump pump.

    With the basement now completely protected, Tony can use his basement as he needs without any water damage.

Foundation Settling Prevented With Push Piers in Longview, WA

    Frank C a local Longview, WA resident saw that his foundation was not level. One side was starting to sink significantly. Frank knew of a friend who worked at TerraFirma Foundation Systems, Patrick Dunn. SO he called the office to have Patrick come out.

    That came day Patrick came to do a full inspection of his property. He recommended the push pier system for the settling foundation, which works by being connected to the wall that is settling or slanting.  Next, the piers are then driven into the ground hydraulically until a suitable loading bearing stratum is encountered.  Over time the foundation slowly starts to lift and eventually will come back to normal. Also he recommended Smart Jacks which are installed in the crawlspace to provide supplemental support for the failing structure.

    With the help of the Push Piers and Smart Jacks, the foundation is no longer sinking.
