Services
Whole House Inspection
Our comprehensive whole house inspections evaluate structural integrity, electrical systems, plumbing, HVAC, and major appliances. Inspectors document findings with hundreds of photos, focusing on habitability-affecting defects while avoiding unnecessary alarm about routine maintenance. Reports include summaries of critical concerns and recommendations for further action.
Termite Inspection
Licensed inspectors perform visual assessments for wood-destroying insects in accessible areas. We identify active or inactive infestations, document damage, and provide treatment recommendations. FHA/VA loan requirements are accommodated, with structural inspections available at no extra charge when combined with whole house evaluations.
Radon Inspection
Certified personnel conduct 46+ hour radon tests using tamper-proof monitors placed in lowest habitable areas. Results determine if mitigation is needed, as elevated levels pose significant health risks. Testing follows strict protocols with windows/doors closed during measurement periods.
Septic System Inspection
Visual evaluations of septic tanks and leaching systems identify visible defects. Inspectors assess aerobic/anaerobic system functionality and provide condition reports. Fees vary based on riser installation status and required excavation for tank access.
Well Inspection
We perform EPA-certified water quality tests for coliform and E. coli, along with 20-30 minute quantity tests measuring gallons per minute. Results help determine if water supply meets safety standards and sufficient volume for household needs.

I recommend OPIS. He was able to come out quickly to inspect the home. I appreciated that he took the time to go over the inspection in person and answer any questions I had.

I can not even believe they did not check the attic at all, however they told me they checked it.
Literally, there is a sign in the attic saying it's leaking here. They did not mention anything about it and told me things in the attic looked fine. I have serious doubt whether they are even qualified to inspect your roof or hvac. They just missed so many things. And they will not be responsible for anything after you paid them. If your realtor recommend this company, it maybe because the realtor know that they will not be able to find the problems in the house and it's easier to close the house

I don’t trust anyone else! Not only have I used them for all of my personal/investment properties, I always refer my real estate clients to them for their inspections. Very thorough and great at explaining and walking the client through everything on the report!

I've used OPIS twice for my pre-purchase home inspections. They were thorough and honest. They answered all my questions and were such a pleasure to work with. I highly recommend using their services for your inspection needs.
