Disaster Recovery Services in the Lewisville Area

Olympic Restoration Systems provides professional disaster restoration and cleaning services for residential, commercial, and municipal clients in TX. Disasters such as fires, floods, and wind storms can leave debris and damage that may compromise a bulding’s health. Though these events may be unpredictable, you can keep us in mind for dependable recovery after the fact. We offer the following disaster recovery services:

  • Emergency water cleanup
  • Fire damage restoration
  • Indoor humidity control
  • Water removal

Moisture that is left unchecked can cause structural damage and problems with mold. Poor indoor air quality has been conclusively linked to lower work productivity, absenteeism, lost tenants, compliance penalties, lawsuits, and worker's compensation claims. Don’t hesitate — call us for thorough, professional disaster recovery services in your neighborhod.

In addition to long-term humidity control, we offer thorough mold removal for commercial and residential properties in Lewisville, TX. We remove any visible mold in addition to employing deeper removal methods that prevent regrowth. To keep moisture levels down and maintain a drier environment, we install the super effective Aspen Air Purifier that covers up to 1,500 sq. feet. Unlike other air purifiers, the Aspen does not emit ozone and only improves your indoor air quality. With easy-change-filters and the ability to remove over 99.97% of particles from the air, the Aspen is right for you.

Effective Radon Gas Mitigation

Radon is the leading cause of lung cancer among non-smokers and is in every U.S. state, including TX. Radon is odorless, invisible, and impossible to detect without specialized equipment. Radon is also not limited to basements — we can find elevated radon levels in rooms as high as the second story. Fortunately, Olympic Restoration Systems is Lewisville’s qualified radon mitigation company, offering radon testing, radon mitigation, and other indoor air quality solutions.

If you’ve never had your home tested for radon, then you should schedule a test as soon as possible. Different factors can impact radon levels in the home, including the source of the radon, how many floors are in the home, whether you keep your windows open often, and the stack effect. We can explain all of these factors to you and install a radon mitigation system that is compatible with the current waterproofing system in your basement or crawl space.

Some items on your home repair to-do list can wait. But when it comes to unsafe radon levels, basement flooding, crawl space damage, or damage from a disaster, quick action can make a huge difference in recovery.

Before and After Pictures from Lewisville

This customer called Olympic Restoration Systems with an urgent situation. A skunk had gotten under their house, in their crawl space, and sprayed during the late evening the night before they called us. Of course, the smell was horrible. The smell was so bad that the customer slept out on the porch with a sleeping bag that evening. They were having a birthday party for one of their grandson’s the next day and needed a quick resolution. They wanted to know where and how the skunk got into the crawl space. While Olympic Restoration Systems was at their home, they also wanted to have the dehumidifier checked to see if there was any damage and to see if it was working properly. They have nice hardwood floors and they appeared to be getting too dry and were separating at the seams.

They contacted Olympic Restoration Systems for an assessment of their home, and for a quote that they were in search of to reduce the skunk smell and their access to the crawl space, as well as checking their existing equipment in the crawl space. An Olympic Restoration Systems Specialist visited the property and proposed a quote to the customer. They proceeded with the crawl space work needing to be completed with Olympic Restoration Systems for their home.

Job Stories From Lewisville, TX
Radon Mitigation System in Lewisville, TX

The homeowner contacted Olympic Restoration because they believed they had high levels of radon in their home.  We sent one of our Radon Mitigation Specialists, Darrin, to the property to perform a radon test, and he sent the radon test to Alpha Energy Laboratories for testing. The results for radon came back with high levels, so Darrin proposed an estimate to the property manager for a radon mitigation system. The homeowner was impressed with the proposal and proceeded with a radon mitigation system from Olympic Restoration Systems.

Mold Remediation in Highland Village, TX

These photos are from a mold remediation job completed in Fort Worth, TX by Olympic Restoration Systems. We were contacted after a homeowner had mold growth confirmed by a licensed mold inspector and needed a licensed mold remediation company. Our Production Team was able to safely and efficiently remove the mold-damaged material and flooring from the unit. In the pictures, you can see where they set up containment and used HEPA vacuums to ensure that mold and other pollutants did not circulate throughout the home during the mold removal process. 

*If you think there is mold in your home, the first step is to contact a licensed mold inspector. Per state law, the licensed mold inspector and licensed mold remediation company must be separate entities. This is a protection for the homeowner. If mold growth is confirmed by a mold inspector, you should be given a mold protocol. The next step is to send this protocol to Olympic Restoration Systems so that you can receive a licensed mold remediation estimate.

Basement Leak in Lewisville, TX

This homeowner called after his basement waterproofing system, installed by another company, failed. He had water leaking in his basement, and wanted to find a solution to keep his basement dry permanently. We sent one of our System Designs Specialists, Darrin, to the property for  a free, no obligation basement waterproofing estimate. His solution involved sealing the walls and part of the concrete floor with PermaFlex, and installing an UltraSump sump pump. The homeowner accepted the proposal offered by Darrin and proceeded with basement waterproofing from Olympic Restoration Systems.

Crawl Space Causing Warped Floors in Lewisville, TX

A homeowner had a wooden floor installed the previous year and was already starting to notice a slight cupping in the floor. After some research, he ran across our website and contacted us to assess whether humidity in his crawl space could be causing the issue. When we arrived, it was confirmed that the humidity was high and there was condensation on his subfloor. He decided to encapsulate. 

First, our team removed the debris and regraded the crawl space to direct water to the sump pump system. A sump pump was installed, along with a dehumidifier. Two wireless sensors were placed to send temperature and humidity readings to a small panel inside the house. Next, CleanSpace Drainage matting was installed and a CleanSpace liner was placed on top. Silverglo insulation was fastened along the inside perimeter of the entire crawl space. Afterward, the vents were closed to ensure no more moisture or condensation were allowed to penetrate the crawl space. This owner can now rest easy knowing that their crawl space no longer has moisture issues.
