BPG Home Inspections
BPG Home Inspections
We are a Full Service Inspection Company. We provide an computer generated narrative style report. We always have a live person (no answering machine) to answer your calls.
"Our inspector, Joe Donnelly, was recommended by our realtor. He was very nice and did catch a lot of smaller things on our home inspection. However, he majorly screwed up on the electrical part of the inspection: he noted that there were a few double tapped breakers that we should get fixed, but somehow did not notice that none of the breakers were GFCI or arc-fault protected. He also missed the lack of sticker on the box, which meant the electrical work in the house had never been inspected (or at least never passed). When we called an electrician in to fix the double tapped breaker issue, he immediately pointed out the non- arc fault, non-GFCI, no inspection situation and was shocked the home inspector didn't notice either issue. We now have gotten estimates of several thousand dollars to fix the electrical issues, expenses we were not planning on. If Joe had found these issues, we likely would not have gone through with buying this house."

He did a great job answering ALL our questions, examining our roof from the inside as well so there would be no surprises. He even identified chimney work for us to be aware of to get repaired. We had no idea it needed work. A crew was on site within DAYS to start and 2.5 days later, our new roof was COMPLETE. The workers were great and left the property spotless at the end of each day. Conrad - project manager - stayed 100% on top of the daily progress, keeping us informed at all times, even with some rain issues to work around.
