A sub-floor is the foundation, the rest of the property is built on. There’s a wealth of information down there. For Building and or Pest Inspectors, the subfloor is often where we discover the true state of a home. A well-maintained sub-floor space will generally have less defects and their nature will most likely be minor. Finding these minor problems before they escalate will minimise headaches and expense. Performing routine inspections is one thing you can do help in maintaining your property and deal with any issues proactively.
