TripleSafe Sump Pump Upgrade Will Keep a Leaking Basement Dry in Alexandria, OH TripleSafe Sump Pump Upgrade Will Keep a Leaking Basement Dry in Alexandria, OH

After moving into their house two years ago, homeowners in Alexandria, OH, soon discovered their 100-year-old house had a leaking basement. Every time it rained, water would seep inside and damage their belongings. Even though they had a sump pump, it was failing adequately pump the leaking water out of the basement. It also lacked a proper lid.

Motivated to address this issue once and for all, the homeowners contacted Ohio Basement Authority after learning about our company through a happy customer and trusted friend.

We then installed the sub-floor WaterGuard interior drainage system that intercepts any seeping water. This water is then directed to the UltraSump pump that replaced the older sump pump system. The back-up battery ensures the sump pump will always operate, even in the event of a power outage. This system also was installed with the larger TripleSafe liner for easy future upgrades if the homeowners choose to do so.

The homeowners now have peace of mind knowing these reliable permanent solutions will always keep their basement dry.

Job Stories From Alexandria, OH
Wall Anchors Stabilize, Straighten Cracking, Titling Walls in Alexandria, OH

After living in his house for 18 years, a homeowner in Alexandria, OH, noticed one of the foundation walls was cracking and tilting inward. The owner was worried these problems could further worsen and lead to safety and structural problems.

After learning about Ohio Basement Authority, the owner was eager to contact us to learn more about how we could help him. He met with one of our inspectors who completed a thorough evaluation of the problematic foundation walls, including measuring the walls for movement. Our inspector then presented the owner with one type of our many reliable foundation repair solutions.

One of our crews then installed several Geo-Lock Wall Anchors on the failing foundation wall. These heavy-duty, galvanized steel anchors permanently stabilize the wall, prevent any further cracking or inward bowing, and offer the best opportunity to straighten the wall because of their unique design.

The owner is pleased these trustworthy repairs were completed to ensure the safety and stability of his home.

Crawl Space Encapsulation and Insulation in Alexandria, OH

After moving into her house, a new homeowner in Alexandria, OH, began to roll up her sleeves and tackle various repair projects to maintain the 125-year-old house. This included addressing the nasty crawl space. This area underneath the house was full of debris and failing insulation.

Concerned the condition of the crawl space could affect the health of the rest of the house, the owner began to research possible repair options and companies. She was eager to contact Ohio Basement Authority for a permanent solution, and excited for us to transform her home’s crawl space.

We did this by first removing the nuisances from the crawl space, then encapsulating the area in CleanSpace liner. CleanSpace is a thick and durable liner that is similar to swimming pool liner. It fully isolates the crawl space from the earth, serves as a moisture and vapor barrier, and helps insulate the crawl space. We further insulated the crawl space by installing SilverGlo insulation panels on the walls and applying spray foam insulation to the band joists.

The crawl space is now properly sealed and insulated, and the homeowner is happy to have a healthier living environment because of this reliable repair process.

It also was slightly tilting inward.

This concerned the homeowners, and they wanted to address these issues so the next owners would not have to worry about them. After learning more about Ohio Basement Authority online, the owners were eager to contact us for a permanent solution. They were equally excited for one of our expert crews to install one type of our many reliable foundation repair products.

We installed several Carbon Fiber supports on the problematic foundation wall. These heavy-duty supports permanently reinforce the foundation wall where they were installed, as well as prevent any further cracking and inward bowing. They also can easily be concealed by paint or drywall.

The homeowners now have peace of mind knowing this trustworthy solution has helped create a safe and stable living environment for the next owners.

SmartJacks Stabilize Sagging Floors in Alexandria, OH

Upon purchasing their house, homeowners in Alexandria, OH, were concerned with the structural stability of the aged building. The home was built in 1890, and it was common to use wooden support systems at that time. Wood can easily rot and fail, and so can other improper support systems that were intended to help correct any foundation failure. The light-duty metal jack posts in the basement and crawl space also were rotting, corroding and failing.

With the assistance of their general contractor, the homeowners reached out to Ohio Basement Authority with the goal of stabilizing sagging floors in the home. After one of our experienced inspectors completed a thorough evaluation, he recommended one of our many reliable foundation repair products be installed.

The homeowners were eager for one of our expert crews to install 30 SmartJacks in the basement and crawl space areas. Unlike typical jack posts, the heavy-duty SmartJacks are made of galvanized steel to enhance their durability. This also makes them rust and corrosion resistant. The SmartJacks permanently stabilize the above floors and help raise them back to the proper level. They also are designed to prevent further settling. But if any settling occurs, the SmartJacks can easily be adjusted.

Now the homeowners can rest easy knowing these reliable repairs have helped them create a safer and structurally sound living environment.
