Job Stories From Portsmouth, OH
Stabilizing Sagging Floors With SmartJacks in Portsmouth, OH

A homeowner in Portsmouth, OH, has lived in his house for several years. But it wasn’t until recently that he noticed some areas of the floors felt uneven and like they were sagging.

The owner wanted to address these problems before serious damages resulted. He previously worked with Ohio Basement Authority on another repair project, so he knew he could again count on us for the right repair solution. One of our inspectors visited to evaluate the support system in the crawl space underneath the house, and he found these supports were starting to fail. Our inspector then recommended one of our reliable foundation repair solutions.

One of our crews then installed several SmartJacks underneath new steel supplemental support beams in the crawl space. These heavy-duty, galvanized steel supports permanently stabilize the floor joists and help raise the floor back to level. They also will not rust or corrode. They are designed to stop settling, but can easily be adjusted if any settlement occurs.

The homeowner continues to be a happy Ohio Basement Authority customer, and he is glad to now have a safe and stable living environment.

Basement Waterproofing and Foundation Repair in Portsmouth, OH

As they moved into their house, new homeowners in Portsmouth, OH, noticed some issues they wanted to address. Water intrusion and damage were obvious, as were cracks on one of the foundation walls.

While searching for the best repair options, the homeowners came across Ohio Basement Authority’s information on Angie’s List. They were eager to contact us and meet with one of our inspectors. After assessing the condition of the leaking, cracking basement, our inspector recommended our reliable basement waterproofing and foundation repair solutions.

We installed the WaterGuard interior drainage system and two UltraSump sump pumps to keep the large basement dry. Any water intercepted by the WaterGuard system is directed to the UltraSump and then pumped out of the basement and away from the home’s foundation. IceGuards were attached to the exterior sump pump discharge lines, and a LawnScape outlet was used to camouflage the end of one of these lines in the yard.

Several PowerBrace beams also were installed to permanently stabilize the cracking, tilting wall. These unique beams can be adjusted during dry seasons to improve the wall’s condition.

The homeowners are pleased these trustworthy solutions were installed to help them create a safe and healthy living environment.

Stabilizing a Settling Garage Foundation with Push Piers in Portsmouth, OH

During the 12 years he has lived in his house, a homeowner in Portsmouth, OH, kept his eye on a potential structural issue. Various cracks in stair-stepping patterns could be seen on the interior and exterior of the home’s garage. This issue can signal foundation wall failure and settlement.

Now that he wanted to sell the house, the homeowner knew he needed to address these issues for safety and resale value purposes. He contacted Ohio Basement Authority after learning more about our company online, and one of our inspectors presented him with the perfect solution.

We installed several Push Piers underneath the settling garage walls. These heavy-duty, galvanized steel piers are mechanically driven down to competent soil so they will permanently stabilize the foundation. They also offer the best opportunity to lift the foundation back to level.

The homeowner now has peace of mind knowing this reliable repair process has helped him create a safer living environment for the next owners.

The Health and Appearance of a Leaking Basement in Portsmouth, OH, is Dramatically Improved

Water has been seeping into a basement in Portsmouth, OH, recently, and the homeowner was concerned the belongings she had stored in this area could be damaged.

She contacted Ohio Basement Authority, and we installed various permanent waterproofing solutions in the basement of the 95-year-old house.

After Ohio Basement Authority previously installed several Helical Piers to correct foundation issues for a homeowner in Portsmouth, OH, the customer did not hesitate to call us again when he noticed issues with his crawl space.

The unhealthy area full of debris and failing insulation was completely transformed and improved by several crawl space repair products installed by one of our expert crews.

PowerBrace System Stabilizes Garage Wall in Portsmouth, OH

A homeowner in Portsmouth, OH, recently began to notice one of the foundation walls in the garage of his bi-level house was cracking and bowing inward. He was concerned with the structural integrity of the wall, and hoped to find a permanent solution to stabilize it.

He contacted Ohio Basement Authority, and one of our expert crews installed the PowerBrace System. A total of five heavy-duty, zinc-plated steel beams were tightly secured against the problematic wall. These beams will stabilize the wall in its current position, and they can be tightened over time for possible wall improvement.

The homeowner now has peace of mind knowing his home will be a safe and stable living environment for many years to come.

WaterGuard, SuperSump, & CleanSpace Create Healthier Basement in Portsmouth, OH

Homeowners in Portsmouth, OH, wanted to sell their home, but first needed to address a significant basement leakage issue. They tried "do it yourself" waterproofing methods that proved to be ineffective because water was still seeping into the basement.

They contacted Ohio Basement Authority, and one of our expert crews installed the sub-floor WaterGuard drainage system around the basement's perimeter. The WaterGuard intercepts any water and drains it to the SuperSump sump pump. The SuperSump pumps the water out of and away from the home through a discharge line. An IceGuard was attached to the exterior discharge line to prevent flooding if the line freezes or becomes blocked.

A back coal room in the older home's basement was also encapsulated in CleanSpace liner. The durable liner was completely sealed over the floor and walls to fully isolate the home from the earth. The result is an attractive, bright, tough, impervious liner, and a healthy home!

The homeowners are pleased to have a healthier basement that will be dry for future owners for many years to come.

Basement Waterproofing with WaterGuard and TripleSafe in Portsmouth, OH

Homeowners in Portsmouth, OH, noticed a lot of water would seep into their basement every time it rained heavily. They spent a lot of money to clean it up, but it continued to be a problem.

They contacted Ohio Basement Authority, and one of our expert crews installed the WaterGuard Basement Waterproofing drainage system and TripleSafe Sump Pump System in the basement.

WaterGuard was installed in the sub-floor to catch any seeping water and drain it to the TripleSafe. Water is then pumped out of the basement and away from the home. The TripleSafe features three pumps, including a battery back-up pumping system that ensures the home will be protected even in a power outage.

The homeowners are happy to have a basement that will be dry and healthy for years to come.

I have mainly horizontal cracks with some vertical along one corner of my basement. After some digging on the outer wall I found the wonderful wet clay. I am getting ready to start an addition on the house and was going to have the contractor dig out the foundation and run weeping tile to the ditch out front but wanted to address the bowing wall before we started anything.
