The first question we get asked is "What is Thermal Imaging? We usually compare Thermal Imaging to an x-ray.
If you go to your doctor with a problem with your knee, the doctor cannot see below your skin so he gets an x-ray and then with all the information he can assess you.
The same is true for your house. If you have a problem inside your wall, either in the basement or main floor, we cannot see behind the drywall. With the Thermal Images (x-ray) we can see what is causing the problem and then give you the solution - 100% accurate.
Let the professionals with the professional equipment and tools diagnose and solve your heat loss and/or mold and mildew problems.
