Home Inspection
Our comprehensive home inspections evaluate all major property systems including structural components, electrical systems, plumbing, HVAC, and roofing. Licensed inspectors identify safety concerns and maintenance needs while explaining findings directly to clients. Reports include digital documentation of issues affecting property value or habitability.
Radon Testing
Professional radon testing follows EPA protocols using continuous monitoring over 48 hours. We provide clear documentation of results and guidance for mitigation when levels exceed safety thresholds. Testing includes foundation and basement evaluations to identify entry points for this odorless radioactive gas.
Annual Maintenance Check-up
Scheduled property evaluations identify developing issues before they become major repairs. Inspections cover weather-related wear, system performance, and hidden structural concerns. Clients receive actionable recommendations for preserving property condition and extending component lifespans through timely maintenance.

Blake was very responsive and able to get my home inspection scheduled and done very timely. He completed my home inspection and was very detailed in his report, even walked through the minor details. He took the time to explain what can be done to improve the home so we don't run into problems in the future. He was very professional and nice to work with. We even had the report the same day. I highly recommend! Thank you Blake!!

Blake was thorough with the commercial inspection. He pointed out even minor details that we hadn't considered, and helped us understand what was well maintained, and what needed some maintenance. Service was professional and he was very nice.
