Crawlspace Smartjacks provide stabilization to uneven floors. Weak and sunken floor joists can cause floors to become uneven. In some cases the Smartjacks assist the existing floor joists in supporting the floor above. In the case of this homeowner, a section of joists was taken out and replaced by a section of Crawlspace Smartjacks.

Crawlspace flooded from irrigation watering Nampa, ID 83686

Do you live near crops? If so the irrigation watering can end up flooding your crawlspace or basement from it, call us for a quote to get your basement or crawlspace waterproofed! 

Standing Water in a Crawlspace

The homeowner called in with concerns about standing water in their crawlspace and wanted to know if there were any major concerns. Water in the crawl can lead to many problems, some of them being mold, fungi, allergens, settlement/sinking, increased heating/cooling bills, smelly damp carpets, and sticking or swollen doors and windows. 

Our solution to water in the crawlspace is our SmartPipe and TripleSafe sump system! Having a good system in place ensures water runs through and out instead of pools and puddles under your home. This helps protect the structure and reduces mold, rot, and settlement risks.

Concerns with cracks?

The customer called us because they had concerns about some cracks in the foundation which was leading a slight amount of water into their crawlspace. We installed carbonarmor and nexuspro. 


The CarbonArmor system permanently stabilizes your home’s foundation walls. CarbonArmor uses fiber-reinforced polymers (FRPs) which are 10-times stronger than steel, yet flexible enough to contour tightly against your basement wall. The ArmorLock brackets bind and secure the CarbonArmor straps to your floor joists making the CarbonArmor solution fast, non-invasive and ideal for quickly stabilizing bowing and leaning walls.

NexusPro® is a silicone-based sealant for joints and cracks specially engineered to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry.

Cracks in your foundation?

The corner of this customer's house was settling. We attempted to install PushPiers, But realize the structure was too light. So we installed HelicalPiers. 


helical pier is a steel shaft with round helixplates that provides a foundation support for various types of structures. ... Ram Jack deep-driven steel helical piers are 2-3/8″ or 2-7/8″ diameter sectional pipe piles. They are hydraulically rotated into the ground to bear on rock or a solid soil stratum.

Foundation wall cracks trigger a number of questions?

Foundation wall cracks trigger a number of questions: Is this a structural crack that compromises the strength and stability of the wall? Will the crack get bigger over time? What caused it? Will the crack allow water to leak inside the foundation? What can be done to fix it?

Leaving these questions unanswered can cause any homeowner to lose sleep. That's why it's smart to have an expert from Foundation Supportworks of Idaho look at your cracked foundation. We offer free inspections and estimates on permanent repairs to cracked foundation walls. 

The good news: Foundation wall cracks can often be repaired quickly and affordably

For example, our FlexiSpan® crack repair method effectively seals stable cracks that are admitting water –a repair technique that’s quick and inexpensive.

Water coming into the entryway in Nampa, ID

Water was entering the basement through the entryway. We had already installed a short section of waterguard and a smart sump pump.  We installed a floor drain in the entryway to catch future water from coming down from the stairway.

Wood Called because she felt like when she looked at her home it seemed to be tilted and that her floors were sloping down, noticing that her floors weren't level.  In her basement, her walls were cracking and were pulling away from the foundation.

Vertical Cracks in Basement Fixed in Nampa, ID

A concerned homeowner found a vertical crack in his basement wall. This crack was only visible on the interior side of the household. There were no other signs of settlement, so this means that there was just a substantial amount of pressure on the basement walls from the surrounding soil. They gave us a call and we sent our expert out to evaluate the situation. Upon inspection, our expert found another vertical crack in addition to the one that was already present.

With the problem identified, our installers used FlexiSpan crack repair system to repair and secure one of the cracks. The other crack was fixed by installing CarbonArmor directly over the FlexiSpan. Now this homeowner can rest assured that these cracks will not spread and that his walls are secured.

EZ Post Pier Restores Sinking Front Porch Support in Nampa, ID

Homeowners in Nampa noticed stones falling off of the support post on their front porch while walking up to their front door one day.  They realized that the post was sinking and the decorative stones around the base of the post were being popped off as they hit the ground.  Not knowing what to do, they called Foundation SupportWorks of Idaho for our expert opinion. 

Our EZ Post product was the perfect solution to this couple's problem. Our experienced production crew carefully removed the sinking post, being sure not to disturb any more of the decorative stonework.  The cement under the post was also removed in order to access the ground below.  The crew pushed the EZ Post pier into the exposed ground, attached a bracket to the top, and reinstalled the original post to it's original position on the front of the house.  They poured new concrete to replace what they removed and also reinstalled the porch railing.

The front porch support post is now back at the level intended by the builder.  With our EZ Post pier underneath, the homeowners can rest assured knowing it won't ever sink again.  Once the decorative stones are reattached, no one will even know there was ever a problem!

Rose In Middleton, Crawl Space Nightmare!

Rose from Caldwell has lived in her home for over 25 years and the first time she found water in her crawl space she called a company to add a vapor barrier.  They told her the 6mil thick liner was the same liner everyone else installed in their homes and that was true. It was only 2 years later that while in her garden Rose notice an odd odor coming from the crawlspace; she took her flashlight and peered into the space. Rose was mortified!   


The black vapor barrier was pull away from the perimeter of the crawlspace exposing the damp dirt and in one corner she could see a large puddle or water. In the large puddle she found mold growing on the wood post that held up her home and she could see the wood had started to rot away.

Rose was not only disgusted by the odor she was living above but she was also scared that the wooden post would snap! She knew that if the post snaped it would cause a ton of damage leaving her home unsafe.


Rose started to look for help; she didn’t want the normal 6 mil thick liner because she has seen how useless it was. She was looking for a real fix to her issue.

She came across our website and found our CleanSpace liner. CleanSpace which is 20 mil think and would seal her home off from the ground water. She also found our SmartJacks which are used to replace beams. She instantly called us and set an appointment for later that week.


For homes in farm areas such as Kuna, Caldwell, Emmett, Middleton, Nampa, Parma and Marsing ground water can be a huge issue. If you find water in your crawlspace or basement please give us a call! We give free estimates! And don’t forget your home will always be your biggest investment, keep it save and enjoyable for your family.
