So you want a professional property restorer?
Of course you do! That’s why you’re reading this Blog!
On the surface, it might look like an easy job of putting in equipment and walking away. Do that... if you want to help mold build up.
Water restoration is a complex trade! It requires a fundamental understanding of: building science, structural building practices, and the science that surrounds water damage restoration. The deeper your knowledge of building sciences and building compositions, and the greater your knowledge is of how building materials respond to moisture, the more likely you’ll be able to increase your profitability and deliver a successfully dried project.
Become a sponge: learn everything you can about the science and let the knowledge soak in.
After all, drying a building is about atmospheric sciences inside and outside the structure. It’s about the molecules and microorganisms that live within your job and it is the application of science that allows you to pull the moisture out.
Here is the good news, this blog is going to simplify the difficult science to help a novice/intermediate restorer make better decisions in the field. This blog won’t replace the courses and hands on knowledge that you will get from the classroom and field, but it will help supplement your learning.
At GTA Restoration, we know it’s hard to master every project—and that’s ok.
We’re going to help you understand the concepts and help you manage all the information that comes your way. By the end of this blog, you will have the skills needed to be able to start drying a building.
We also have a new Moisture tool that can help you simplify your water damage property.
The time you spend with a qualified trainer who has field knowledge and can allow you to learn by relating to their experience is key. If you are using GTA Restoration, you’ll have the playbook that helps you unleash the full potential of saving your property.
However, note that nothing replaces the technical training of the IICRC and the advance learning of the Restoration Industry Association.

Sometimes, we forget the fundamentals of Water Damage Toronto.
Our goal as a restoration professional is to return the building materials to a dry standard or the same moisture level as the other unaffected materials in the building, or to remove, clean, and disinfect the structural materials. The dry standard is the target moisture content for the particular material in its normal (unaffected) state within that structure/specific micro-climate. Materials become ‘dry’ once they reach the dry standard.
This level depends on the type of material, the location of the material in the building, and even where you live and the time of the season.
The various tools you use on the project may also provide you with relatively high or low readings depending on the circumstances. For example, a piece of oak wood in a dry climate might have a dry standard (drying goal) of 6% moisture level. Whereas the same piece of wood on the East Coast might have a dry standard of 10%.
These levels can fluctuate structure to structure and change throughout the year depending on the prevailing weather. This is why it is highly
Moisture Level (ML):
the amount of moisture contained in the material on a relative scale. Moisture level is used when the tool is not calibrated for the specific material. (IICRC S500 V4, 2015, 328)
Moisture Content (MC):
the amount of water contained in a material, expressed as a percentage of the weight of the oven dry material. If a restorer is measuring materials with an instrument that is calibrated for that material, then it is recommended that the term Moisture Content be used (IICRC S500 V4, 2015, 328).
recommended that a restorer does not use a regional dry standard for drying materials, but uses a specific dry standard for that structure when possible.

A Personal Story...
The Laws of Thermodynamics
Understanding the forces that you apply to a building will increase your chances of success. Thermodynamics are the laws that manage energy. For this blog, we’ll simplify the laws. You can apply them to your jobs as these concepts will help you understand drying.
LAW OF EQUILIBRIUM
Think of air as having energy. An easy way to do this is to look at the weather. A fierce thunderstorm will often follow a hot, humid day. Hot, wet air has a lot of energy in it. You rarely see a thunderstorm in the winter in Canada and the northern United States because colder air has less moisture and energy to create those spectacular storms.
Applying Thermodynamics to your jobs
As we take the Laws of Thermodynamics and apply them in the real world, it gets complicated as you have many different temperatures and heat energy loads in and around the building. It takes a lot of energy to evaporate moisture into the air. (Law #1 says we cannot destroy energy, we can only transfer it) so as we release the moisture from the materials into the air, the air is now holding onto that energy. For air to move energy, it needs to hold the energy. According to the second Law of Thermodynamics, the Law of Equilibrium, energy in the air wants to balance with an area of lower energy in the surrounding environment.
