"Dominick was great! We hired Dom for a buyer's home inspection. Called back the same day within hours. Polite on the phone and patient. He was very thorough and spent about 2.5 hours inspecting a 2800 sq ft house. He was testing the radiator in the middle of summer. He was up and down the ladder going up to the roof. Very knowledgeable, knows the codes, and produced very detailed inspection report accompanied with pictures. In addition to identifying a potential issue, his report also explains the both the cause and potential solutions. We will certain hang on to the report for future reference to keep up the maintenance. Dom spent an hour on the phone afterwards to answer our questions after reviewing the inspection report, he also anticipated some of our questions therefore was a great resource in estimating the cost to address the issues. Again, very patient and did not rush us off the phone and this is after he was already paid. In fact, we will probably have him come back to the house for inspections on regular basis to ensure continued safety and comfort. Competent and reliable, highly recommended!"
