Before & After


Installing Helical Piers Near Clairfield, TN
The foundation of this home near Clairfield, TN was underdoing settlement. Settlement happens when soils and ground beneath the structure shift or are washed away. To fix the problem, the team installed helical piers, which look like large screws and anchor the home to strong surrounding ground. With this system in place, the house should be stabilized for years to come.


Using PolyLyft to Bolster a Sinking Porch Near Eagan, TN
This porch located near Eagan, TN was sinking, probably due to the weight of the slab and the washing away of soils. To fix it, Master Services drilled holes at strategic spots along the slab, then injected them with PolyLyft. As the polyurethane expanded, it raised the slab to an even position.


SmartJacks support installed in Clarkrange, TN
A couple residing in Clarkrange, TN, contacted Master Services seeking assistance with sagging floors in their living room. Our team conducted a comprehensive inspection of their crawlspaces, carefully identifying the specific areas in the basement that required support. To effectively tackle the issue, we employed our trusted Smart Jacks system, specially designed to address compact spaces. These specialized jacks offer robust support for weakened crawlspace beams, providing a long-term solution to rectify sagging floors.


Helical Pier Installation in Allardt, TN
In Allardt, TN, a concerned homeowner sought assistance from Master Services regarding their house’s foundation. Our experienced team conducted a comprehensive examination of the property’s perimeter. Through careful analysis, we determined that the appearance of cracks was a direct consequence of soil subsidence, particularly considering the slope on which the house was situated.
To effectively address the problem and prevent further damage, we proposed the installation of helical piers. These specialized piers are designed to provide robust reinforcement to foundations, specifically tailored for the prevalent clay terrain in the local area.
By implementing these helical piers, the homeowner can establish a solid foundation and ensure long-term stability for their property. This proactive measure fortifies the structure against the adverse effects of soil subsidence, providing peace of mind and safeguarding the integrity of the house for years to come.


Pier installation in Alpine, TN
Our team at Master Services responded to a house in Alpine, TN where settling of the front side had become a problem, causing further complications over time. To mitigate the issue and ensure lasting stability, we installed helical piers close to the front steps to reinforce the foundation.


Using PolyLyft to Raise a Sinking Driveway Near Hilham, TN
The team visited a home near Hilham, TN that had a sinking driveway pad. Often, water from rain works its way underneath concrete and washes away soil. The weight of the concrete also will cause settlement. To fix this slab, our team injected it with PolyLyft. The team drills holes at strategic intervals along the slab, then injects them with the high-density polyurethane. As the substance fills the voids beneath the slab, it raises it to an even position.


Helical Pier restored a foundation in Allons, TN
Master Services recently responded promptly to concerns about a front porch in Allons, TN. Our highly skilled team quickly identified cracks and sinking in the porch, a common issue caused by soil settling. We efficiently resolved the problem using four helical piers. These devices connect the cement footing to the solid ground beneath the house via steel brackets, with a unique shape designed to grip the clay-rich soil effectively. This solution allows for a quick fix that can be accomplished in a day.


SmartJacks Installed in Historic Log Cabin in Townsend, TN
In this historic log cabin, years of settling had caused significant sagging in the crawl space. The log joists were bowing under the weight, and the original rock and concrete foundation walls were bearing too much pressure. An attempt to stabilize the area with a jack from another company had failed–it wasnt lifting correctly, leaving the floor uneven and the foundation under strain.
With our SmartJacks system expertly installed, the sagging floor has been lifted and properly stabilized. The new system effectively supports the log joists, taking the pressure off the foundation walls and restoring structural integrity. Now, this cabin stands on a much stronger foundation, ensuring long-term stability and peace of mind for the homeowner.
