Job Stories From Williamsport, OH
Stabilizing and Leveling Sagging Floors in Williamsport, OH, with SmartJacks

While they have lived in their house for almost 20 years, it wasn’t until the last few years that homeowners in Williamsport, OH, began to notice structural issues with their home. Several areas of the floor seemed to be sagging and unlevel. These issues could be the result of foundation settlement or improper supports beneath the floors.

The owners wanted to fix these problems once and for all, so they began to research how to best address them. They contacted Ohio Basement Authority after finding information about our company online. They met with one of our inspectors who completed a thorough evaluation of the floors and the support system in the crawl space under the house. Several floor joists and shimmed colulmns were failing to properly support the above floors, so our inspector recommended one type of our many reliable foundation repair solutions.

One of our crews then installed several SmartJacks in the crawl space. SmartJacks appear similar to typical jack posts, but they are far superior. These heavy-duty supports are made of galvanized steel, which enhances their durability and makes them resistant to rust, corrosion and rot. SmartJacks permanently stabilize the above floors and offer the best opportunity to lift them back to level. They are designed to stop settlement, but can easily be adjusted if any settling occurs.

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

Permanently Waterproofing a Leaking Basement in Williamsport, OH

After living in their house for three years, homeowners in Williamsport, OH, noticed water seeping into their finished basement. This was especially concerning because of the media room and workout areas in the otherwise pristine basement.

The homeowners wanted to address their leaking basement and prevent any potential damage to their home. They were eager to contact Ohio Basement Authority after learning more about our company through our website. After one of our experienced inspectors completed a thorough evaluation of the home, the owners were equally excited for one of our expert crews to install several permanent basement waterproofing solutions.

We installed the WaterGuard interior drainage system in the sub-floor to catch any seeping water. This water is then drained to the reliable TripleSafe sump pump, and from there it is pumped out of the basement and away from the home. Two IceGuards were attached to the exterior sump pump discharge line, and new downspout conductor lines were installed on the property.

The owners now have peace of mind knowing these reliable repairs have helped them create a safer and healthier home that they will be able to enjoy for many more years to come.

We had a home inspector come to our house and he made the following notations: crawlspace is damp with some slight standing water. Floor where our water heater sits right above it is weak a has rotted wood. Can we have a ballpark estimate of how much fixing this would cost?
