My name is Jerry and I founded Master Service Group back in 2000. Prior to providing mold services, I worked as a home builder focusing on older home renovations and improving energy efficiency. These renovations centered on making buildings more energy efficient and also the remediation necessary to combat the effects of environmental pollution.

I fully understand how buildings are put together and even more important, know how to solve building problems without wasting money or time. I started gaining relevant experience when I was about 15 workig with my father in construction business, and so far I’ve had 17 years of intensive career in the subject. I supervise all my jobs and I’m always on a working site with my crew.

We noticed a large number of common mistakes made by other contractors and even home designers that resulted in significant risks of mold on projects. Together we concluded that there was a lack of properly trained and specialized people in Residential and Commercial Mold problems. Many mold inspectors and remediators have quick and short education courses but no work experience whatsoever.

Their lack of knowledge may threaten your health and even your life. Using my indispensable knowledge of building as a foundation I have become certified in mold inspection and remediation. I understand building construction and water problems that cause mold. My aim is not only to get rid of mold in your house, but also to prevent it from coming back again by fixing the root cause!

I didn’t pay attention to my own house issues until I became a father and I realized the importance of a healthy home. I want my family to live in a safe place. We spend at least 50% of our lives in our houses. I decided to do everything it takes to make my house green so my family can breathe clean air.

It is important to inspect a building and ensure that it is in good condition as well as to ensure that there are no harmful mold species. You should be aware that mold may be hidden inside walls or other places where you cannot see it. Most of the foreclosures and short sale houses are being sold with mold issues. Those houses have not been used (no heating, cooling, electricity, etc.) for several months or even years. A vacant house also receives little or no sunlight through closed shades and no air movement with the fan off and the doors locked. It is an ideal condition for mold to grow.

I know many cases when some vacant houses were robbed and copper pipes and wires from the plumbing were removed without shutting off the water supply. Standing water was a concern for mold growth. Mostly, house sellers just incorrectly dry out the house and paint the walls to cover the moisture stains but it does not mean that the house is safe for its occupants.

I recommend mold inspection and indoor air quality screening as part of any real estate transaction. Make sure you buy a safe house unless the house is being sold “as is,” in which case the inspection is just for your own benefit so that you don’t buy a house with hidden mold.

Many important tasks must be completed after we leave your property

  • Samples, if collected, will be sent to an independent microbiology laboratory for analysis.
  • A Mold Inspection Report is created using the information collected during the inspection including color photos, moisture readings, and relative humidity readings. Our Mold Inspection Reports are comprehensive and detailed, but also easy to read and understand.
  • You will receive a telephone call from the professional assigned to your project to review, in detail, the lab results from the mold testing, our conclusions, and our recommendations.
  • Getting rid of mold in the attic, basement or crawl space is used to be one of the most “popular” concerns addressed by our clients after the home inspection.

The following steps are intended to be our guide-line of the most common elements of a mold remediation project. We recommend not to skip any of these steps below.


Preparing the work area

Preparing the work area with containment barrier/airlock/chamber and Negative Pressure Equipment. We begin every remediation process with site preperation. We isolate the mold affected area from the rest of the building with plastic sheeting sealed with tape. We put down proper floor protection leading to where we will be working. These steps protect your building from spreading the mold spores around other areas.


Kill & Remove Mold

Tear out and properly bag all the non-salvageable materials(drywall, insulation, carpet, etc). The removed moldy materials are disposed off carefully away from the property so that it does not cause any harm to human health. Next, we apply our 100% naturally derived mold remdiation disinfectant to the rest of the structure (all types of wood & hard surface area). In this step the mold from the surface area is killed and removed(stolon i rhizoids)


Removing Mold Stains

It is absolutely necessary to remove all the mold stains otherwise home inspectors will believe that the mold is still active. We always leave a fresh and clean looking post remediation area.

There are two basic methods of stain removal we offer it, either chemically or via dry ice or soda blasting. We either apply the stain removing solution, to the wood and other surfaces; or we go through the more costly and time consuming process of dry ice or soda blasting the wood.


Killing the Roots of the Mold

The mold species on the surface are killed(step 2) but the roots of the mold are left intact causing the mold to return soon. We use our products to kill the roots of the mold(mold roots only grow 3/16’s of an inch into the wood). We make sure that mold won’t come back. In this step we apply our products for eradicating fungus off of wood and for protecting wood from future infestation.


Ozone Treatment

To make sure that we don’t leave the structure contaminated with spores we use Ozone to kill mold. Every house has nooks where liquid products can’t reach. The use of the gas out is necessary in order to guarantee the destruction of any invisible spores hidden in every cranny.


Air Duct/Ventilation System Cleaning

To remove mold and harmful bacteria from your home air we completely clean the furnaces, fan motors and coils with the proper HVAC cleaning solutions. After, all the duct cleaning is completed, then we sanitize the entire system with an odorless sanitizer, which is non-toxic. We want to make sure that the ventilation system is not infected with mold.


Final Inspections

Post-remediation verification and clearance testing for mold and bacteria is a necessary process to ensure cleaning job is being done properly. Clearance Testing consists of a visual assessment for mold problems in area of remediation activities and the collection/analysis of samples (air quality test, swab, lift samples) in these designated areas. We take air samples in other rooms to make sure that cross-contamination of non-contained work areas has not occurred.


Site Clean Up

When we finish we make sure to clean up all of our mess. We give you your house back in the same condition we found it except mold free!

After the mold removal is completed, we recommend to hire professional contractors who are experts in the field. Mold issues can be sometimes linked to construction defects. A professional contractor should know and understand the importance of taking the proper steps to make sure that repairs won’t cause mold to grow again.

For example: a very common mistake contractors make, is the installation of drywall that comes into contact with the concrete floor in the basement and suck up moisture. Mold and fungus will return on new materials within a few months.

Wet drywall can easily develop mold that does not go away!


To prevent mold from growing in an attic, a contractor should remove excess moisture in the air by making sure that no outside water is gets in by way of leaks or failing gutters.


Make sure that you hire a trained contractor who knows how to remove humidity by providing a proper ventilation and insulation in the attic otherwise, mold will likely return.
