Eco-Seal Home Solutions has been drying up and fixing problem basements all across Ohio for years. We are located in the middle of Amish Country (Holmes County) which has provided us with an employee base that has helped hold a high standard in providing value to you the Customer!! Call us for STRAIGHT ANSWERS, SIMPLE SOLUTIONS.

"We had chalking around the base of our basement walls. We met the Eco-Seal representatives at a home show and set up an appointment for someone to come to our home to give an estimate for repairs. At the appointment we were told that we needed excavation around the house, waterproofing coating and membrane on the outside of the foundation, then a backfill of rock. We agreed to the process. What was not explained is that the drain tile that was going in the bottom of the trench would be emptying into our sump pump. As a matter of fact, during the process I was under the impression that it would empty into the downspout pipe that drains to the street. When the work was done, we started to notice that the sump pump was running every 10 minutes during rain. Before the work, it ran just a couple of times a year. I chalked it up to the system working to keep the moisture away. This past Sunday, we had a storm. The power went out for about an hour. The sump pump was not working. We bailed water for almost an hour to prevent our basement from flooding. On Monday, we called Eco-Systems and were told that it stated in our paperwork that the drain would empty into the pump. Sure enough in tiny, handwritten print, we found this statement. Now we have gone from having a little chalk on the floor to having the very real possibility of the entire basement flooding in case of a power outage. Tuesday night, after spending the day researching how to resolve this issue, the power went out again. MY HUSBAND AND I SPENT 5 HOURS, 48 MINUTES BAILING WATER AND RUNNING IT UP THE STAIRS IN BUCKETS. The water was coming in so fast, we couldn't stop the process or the sump would overflow. We ended up having a plumber in to install a battery backup sump. This will only work for a few hours during a power outage. We will eventually have to have a generator installed at a cost in the thousands so we can leave for vacations and such without having to be worried the entire time that the power will fail and our basement will flood. Eco-Seal did send out a representative today. He apologized for not having told us about this possibility. I repeatedly asked that he do so for future homeowners. This should be an informed decision on their part. I went so far as to suggest that there be a caution included in the written information given to prospective customers. I hope this company makes some changes based on our experience."

FAQs for biohazard remediation projects in Walnut Creek, OH

There are several instances where household biohazard cleanup would be needed. All in all, anytime an event can potentially expose people to chemicals, pathogens, or viruses, a biohazard cleanup company must be called. These events can include:

  • Sewage backup

  • Unattended death or crime scene after death

  • Virus decontamination

  • Medical waste disposal 

  • Animal waste disposal 

  • Odor control   

  • Hazardous chemical removal

The cost of biohazard cleanup averages between $3,000 and $5,000 for most homeowners. Some services, like sanitizing high-traffic areas or sanitizing surfaces from a virus, cost closer to $1,500. However, other circumstances, like the extensive cleanup after a major sewer backup, could cost as much as $25,000. 

While a biohazard cleanup sounds like a scary process, knowing what to expect can help ease your concerns and set you up for success. It’s good to note that more than one professional might be needed depending on your situation, but that will be determined during the assessment. What you can expect during a home biohazard cleanup is the following:

  • Assessment: The first step in this process is for a biohazard cleanup professional to assess the damage. They create a report that includes the biohazard safety level, the needed damage cleanup, and the time it should take to complete the project. 

  • Setup: The cleanup professional prepares the site to prevent cross-contamination and reduce toxicity risk. This process can include tarping and creating decontamination zones. 

  • Removal of surface contamination: Any contaminated materials are removed from the area, starting with large materials followed by small ones. The professional can assess any floor-related damage once everything is removed from the site. 

  • Salvaging items: The biohazard cleanup professionals assess which items can be saved and which are contaminated beyond the point of saving. Those deemed unsafe will be disposed of immediately. 

  • Waste disposal: The next step is carefully disposing of the hazardous waste. Your professional will place the contaminated items in specific containers to keep the contamination from spreading.   

  • Disinfection: The house will be disinfected and odor-neutralized. Even more minor details, like light switches and bulbs, will be disinfected so that they do not recontaminate the area in the future. 

  • Restoration: Once the decontamination is complete, the last step is to restore the home. This includes repairing the damage to flooring, walls, or even the home's foundation.  

Most homeowner’s insurance policies can help cover the cost of biohazard cleanings for specific events. Biohazard events like unattended death, infectious disease, and medical emergency are generally covered, as are flooring and drywall repairs. It’s best to check with your insurance company to see what is specifically covered.

One of the best ways to prepare for a home biohazard cleanup is not to touch anything. Do not remove belongings, even if they are of value or importance, from the area as they are likely contaminated. It’s essential not to use any cleaning products of your own, as the cleaning company will be using chemicals that could interact with your products. 

One thing you can do to prepare is take pictures of your space and belongings that need to be cleaned, especially if you plan on filing a claim with your insurance company. In addition, take time to make a list of items that are valuable, sentimental, or otherwise important. The cleanup company must evaluate these belongings to make sure they are safe.
