"Angel did an amazing job pumping out over 6,000 gallons of water from under our house! Diego came out very quickly to initially assess the damage and then Angel and his team started pumping the water out just a few hours later. They worked hard from 8pm to 2am! Angel was so kind, professional, and helpful throughout the whole process! He responded to all my texts so quickly and communicated with the office for me to get all the documentation that my insurance needed. He even followed up to make sure I had everything I needed. Angel came back multiple times to check on our house and make sure everything was drying properly and that there wasn't any further damage. He left the fans under our house for over an extra week for no additional charge to make sure it was completely dry. Angel was awesome and offered the best customer service!"

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."

"This company was hired by my home insurance as a subcontractor and gets paid directly by the insurance. And yet, they filed a frivolous mechanics lien against my property only a month after the work, without providing any prior preliminary notice. This is after I received a letter from the insurance company stating that everything was paid in full. Instead of checking up with the insurance company for any discrepancies or contacting me to discuss the matter further, they just jump right into filing a frivolous and invalid lien. Looks like this is what this company usually does to the homeowners after just one billing cycle based on other reviews online. This is their go-to billing method. Unconscionable and unethical! I will have to hire a lawyer to look into their unusual billing tactics. Not only that, they left my window frames damaged, and left a sharp metal spike sticking out on my bedroom carpet. I could have gotten seriously injured if I stepped on it. They also left items damaged from the demolition, which needed to be hauled away, with sharp nails sticking out, right in my bedroom. The gentleman who came out to do the initial evaluation was nice, but other employees seemed unhappy. Terrible company!"
