Our Services

Residential Inspection with Infrared Imaging


We follow a comprehensive Residential Standards of Practice. This means we will perform a non-invasive inspection of the visible and accessible structure, systems and components of the home, inside and out, from the foundation to the roof, using the latest tools and technology. We will email you a report the same day, and our job isn't finished until you understand everything in it. 

Radon Testing


Radon is a colorless and odorless radioactive gas that is produced by decaying uranium. It's present in nearly all soils, and very low levels of radon are found in the air we breathe. Long-term exposure to high levels can cause lung cancer. Testing is the only way to know your level of exposure in your home. We test Radon Levels using the E-Perm Radon Testing System. 

Sewer Scoping


Did you know as a homeowner it is very likely that you own the main sewer line that runs from your house all the way to the main city tap? Sewer line repairs can cost you thousands of dollars! We perform Sewer Scope Inspections by running a special camera through your main sewer line and we record a video of what we find and include the video in your report.
