25 EMPLOYEES NO SUBS.
"Excellent company. Iwas freaked out and they calmed me down (call them before you lose sleep!) It's not as bad as it seems. Showed up right on time. Gave an excellent consult that didn't feel rushed nor about just making money (instead.. doing it right!). The actual remediation (all the dry wall in the bathroom, cutting new electrical holes, etc was done to perfection with a clean air test and no debris. They respected HOA rules and they got all this scheduled after permits. It was a seamless stress-free process and ironically it was also the most affordable."

Buyers Protection Group (BPG)
Buyers Protection Group (BPG)
At BPG, we believe home inspections shouldn't end at the driveway. Our inspectors and engineers undergo thorough background checks and must meet ongoing training and performance standards -- they are a selective group of professionals.With so many inspection companies to choose from, how do you select one that fits your needs? We've earned a solid reputation for standing behind our work and providing distinct value advantages that help protect our clients.
"BPG Inspections Failed to Honor Their Guarantee or Take Accountability Summary: In my experience, BPG Inspections failed to uphold their guarantee, and I encountered poor follow-up and vague, shifting justifications for denying my claim. Details: I hired BPG Inspections in Pensacola, FL, to inspect a home I purchased in April. The inspection occurred in March, and I moved in during May. Within a few days of moving in – well within the 90-day warranty period – I discovered two issues that the inspection report had explicitly marked as functional: 1. The garbage disposal unit did not work (it made a soft noise but did not function). 2. The HVAC system failed to deliver air to the kitchen and adjacent bedroom, though the inspection report had indicated the air handling was operational and in good condition. I promptly emailed BPG about these problems, and while the inspector initially responded, I was then passed to their claims department. After repeated follow-ups, I finally received a call on June 23rd – nearly a month after reporting the issue – only to be told that neither issue was covered under their warranty. I raised the following concerns: 1. For the HVAC, the inspector had confirmed it was functional in an email, contradicting the claims department's later justification that it could not be tested. If no air reaches two rooms, it should have been evident during either heating or cooling tests – this was missed. 2. For the garbage disposal, I was told it was a "kitchen appliance" and therefore not covered, despite it being a fixture included in inspections. When I asked where the warranty excluded it, I received inconsistent explanations. At no point did the company offer to re-inspect or further investigate these issues. I expected more accountability from a professional inspection service – especially one offering a guarantee."
