"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."
