Colonial Inspection Services, LLC, is one of Louisiana's most experienced Inspection Companies. We believe our experience sets us apart from the rest. Give us a call today.

"We hired Julie to come out and do an inspection for mold and/or issues that would indicate a potential for future mold. She was the most thorough and knowledgeable inspector of any type that we have ever encountered. She is super kind and took the time to listen and gather information about our past and current situation so she could understand and offer solutions and advice that would best suite our needs. Julie took A LOT of time to teach us about our home. As she did her inspection, she pointed out areas that needed addressing and taught us how to take care of those issues. We are so thankful to have her help, advice, and knowledge as we move forward in assuring that our new home is a safe and healthy environment for our family. I highly recommend hiring her especially for families with environmentally sensitive individuals. She offers a kind, calm, and knowledgeable approach to dealing with any issues that need to be addressed."

When you have mold, making the correct decisions right away is critical. Whether it?s mold in your home, school, place of work or apartment there are many factors to consider. Will you be seeking property damages? Is anyone sick from mold exposure? Do you just want to test to be sure your environment is safe? Do you need Post Mold Remediation Testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It?s important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages & property damages require different environmental tests to prove your case in court. Tests that a common or inexperienced mold inspector would not typically use or know to use.

Since All Dry Services opened in 2014, we have dedicated our professional team to assisting homeowners who are dealing with the aftermath of disasters. Time is important to us: We get the job done right the first time all the time; we show up on time and ready to work; we time our services to fit your schedule; and, most important, we understand that your call to us comes at a sensitive time.

"Phil, the remediation tech, was thorough, professional and always on time. He took his time to go over my entire 4600 sq ft. duplex and pinpointed the areas of concern to only a small area of one bedroom and a small area of the kitchen. He worked diligently and was patient with me as I questioned him throughout the process. Keith, the owner, was patient and thorough in explaining the process to me. Overall, working with All Dry has been a positive experience and I would certainly not hesitate to recommend them."

Biohazard remediation services FAQs

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.
