"Excellent, as usual. I have been using Larry's services for a few years. I have a cream carpet with a lot of mileage on it. He always manages to make it look good again with his thorough cleaning and deodorizing. Larry is reliable, punctual, efficient, and professional. I don't hesitate to call him, and would highly recommend his services."

"Overall experience Terrific. Joseph is one of the most honest, straight forward guys out there. I am very thankful with God that he leasing me in the right way so that I would choose his company over the other companies out there. I’m the beginning I thought that the price was a bit high for my budget but then later I realized the skill level that he does in each one of his kinds of inspection he offers is unbelievable. I owe Joseph my life he helped me convince myself that there truly was a serious mold problem with the house that I just bought not even 1 year ago. So I moved out from my new home in the mean time before my health continues to get in more delicate situation. The mold odor has now begun to cause me to have asthma which I never ever had before in my life. The bank/ realtor Home inspection report of the home never caught any of this bad mal fowl odor and mold infestation from underneath the home. It’s crazy how some of these home inspection still are able to keep their business license when they are worth no good at all. Trust me you won’t regret yourself by choose Guaranteed Property and Mold Inspections. They are by far the best out there. They provided me with a very detailed reports which has lab results from samples they sent out and everything."

"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!"

Radon Detection and Reduction questions, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.
