"I’m a first time home buyer and was very anxious and nervous during the inspection, Richard was my inspector and was very helpful, and even cracked a couple jokes to keep me calm! He looked at everything! I was amazed by how thorough he was and his breakdown of the inspection was very helpful. He made sure I understood what he was saying and he pointed out things to me! Very friendly. I will recommend this company and Richard to everyone I know! Thanks Richard for a positive experience!"

Both home and commercial inspections with Onega & Sons Inspection Services allow our clients the option to choose from many additional specialty services. From mold to sewer scope inspections, we’ll put your mind at ease knowing your property is safe.


Mold Inspection

Concerned about mold or air quality? Professional mold testing and laboratory analysis can help you to identify specific mold and allergen types so you can move forward with a correct remediation plan.


Well Flow Inspection

How much water can a private well provide to your home? A Well Flow Test provides information on the well's production, pressure, and confirms proper operation of well system components.


Water Bacteria Test (Standard / FHA)

Determine the quality of a home's water supply with professional water testing and laboratory analysis, scanning for dozens of parameters including bacteria, lead, arsenic, uranium and more.


Radon Testing

Utilizing the latest technology in radon monitors, we help you to acquire a clear picture of what’s in the air you breathe, contributing to peace of mind and a healthier home environment.


Septic Dye Test

Dye testing can determine where the wastewater from your property is going as well as verify if household appliances and laundry facilities are connected to the system or confirm if two homes are connected to a single system.


Sewer Scope Inspection

Sewer and septic system problems can cause major issues for a home. A sewer scope inspection can identify issues such as pipe obstructions, tree root intrusion and sewer line bellying which can be costly and even hazardous if left uncorrected.
