Property Inspections

Whether you’re buying or selling property, an inspection provides peace of mind as you make purchasing decisions. According to a recent study by the American Society of Home Inspectors and the National Association of Realtors, 8 out of 10 homebuyers order a home inspection as part of contract negotiations. They understand that having as much information as possible can reduce initial moving stress and provide direction on future maintenance plans.

To give clients added service, John has completed Building Science Thermography training. This allows him to offer infrared services to commercial clients. Infrared camera technology uses the thermal properties of objects to help "see" inside walls and ceilings. This can help pinpoint problems with insulation, moisture intrusion and electrical wiring that would be hidden during a standard visual inspection. Ask us about infrared services today!

Inspection savings

NPI inspections are unbiased.  An objective property inspection report not only saves you time, it gives you a clear, concise checklist of information regarding your home or commercial property and an understanding of the current condition of all major systems. This is true on both existing and new housing stock.

For some, it’s easier to understand that an older home will be in need of some maintenance and repairs. After all, you are purchasing a “used” piece of property.

Did you know? A new home can be just as demanding and expensive. According to a National Association of Home Builder’s study on new home buyer callbacks released in March 2006, home builders receive an average of three callbacks on each new home they build and spend an average of $476 on repairs. Having a home inspection completed prior to closing on a new home, means you move in after problems are fixed so you can enjoy your new purchase.
