"It’s not often that a reviewer praises a contractor for what he DIDN’T do. Austin Ireland, the owner and operator of Drytek, didn’t propose spending several thousand dollars on encapsulating my wet crawl space. He said that in my case encapsulation might not be cost effective. You see, my 50 year-old home’s foundation consists of 8”x 8” wood posts, with the foundation’s perimeter enclosed by 1”x 6” boards, slatted to allow for ventilation. The layout of my irregular crawl space posed other installation problems as well. Among other things, insulation panels would need to be installed to form walls in addition to the vapor barrier and a large dehumidifier. Four contractors/salespersons preceded Drytek’s Austin Ireland. One simply said there’s nothing that can be done. Another proposed encapsulating the crawl space from the OUTSIDE, but thankfully never followed up. Another did an evaluation, but never returned my calls. Dryzone wanted $8,500 but offered a pressure tactic $425 discount if I signed a vague contract the same day the salesman came. Later the salesperson said the installation of insulation boards would raise the cost significantly. The salesperson at Dryzone also said he would call back with details, but didn’t. Drytek’s Austin Ireland, on the other hand, took more time than any of the others to carefully examine my crawl space. I crawled with him as he pointed out the condition of my crawl space and the challenges of encapsulation. By this time, my own research had better prepared me to better evaluate proposals. I found him to be knowledgeable, straightforward and honest. I was a highly motivated prospective customer. Last year a HVAC system had been installed with the air handler, electronics, and ductwork in my crawl space. The moisture in the crawl space last summer was degrading the new system. So what did Austin Ireland of Drytek propose? Four centrifugal snail fans joined together by extension cords, placed strategically in the crawl space. These are not exhaust fans to ventilate, but rather air movers like you may have seen in public bathrooms to dry floors. He even showed me what to do, and wouldn’t take any payment for his visit. After investing $400 the next day at Home Depot , I located the fans, connected the extension cords to the receptacles in the fans and waited for the heat and humidity to test Austin Ireland’s theory. It is now six weeks later and we have had three prolonged periods of hot, humid weather during which I have activated the fans. THE CRAWL SPACE HAS STAYED AS DRY AS A BONE. Amazing! The vast majority of wet crawl spaces need to be encapsulated; mine did not. But it took a trustworthy expert whose ethics mattered more than profit to present the best solution for me. Austin Ireland, owner and operator of Drytek, is that person."

Mold, allergens, dust and air quality are in the forefront of our minds. Put your mind at ease knowing our IICRC technicians will get your air ducts professionally cleaned with our state of the art cleaning truck and tools. Call today

"The cleanup job they did was good. But if you would like them to quote you an amount for cleanup and then when the job is completed double that quote and bill your insurance go ahead and use them. We had a sewage spill underneath of our house and called this company to come and clean it up. We were quoted a little over $4000 to complete the job. When we got the breakdown from the insurance company of what they were paying it was double the amount of what we had been quoted. Spoke to the operations manager and owner who both did not care that this is taken place. They were just concerned with being paid for the work. You want to get caught with a bill you didn’t expect, go ahead and use them."

FAQs for biohazard remediation projects in Mardela Springs, MD

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.
