- What sets me apart from other top inspectors is rather than spending 2-1/2 to 3 hrs. merely documenting the home's structure, systems, and components, and identifying deficiencies and potential problems; I focus upon teaching you about the home. Yes, it will be me, not a (surprise) employee, who will be serving you. Rather than simply enabling you to make informed decisions regarding your contract to purchase, I am enabling you to understand the specifics of your future home, which thereby enable me to teach you how to operate its systems most efficiently, reduce your energy costs, and how to maintain your home and protect your investment. You needn’t ask if you can accompany me and ask questions — I will arrive about an hour before you to set up my program, and document exterior conditions. Upon your arrival we will enter, conduct a detailed orientation, then inspect the home together. During which I’ll explain everything and answer any questions you may have. When we’ve completed inspecting, we’ll review the draft of the upcoming report, so you’ll know what issues will be in the report before we leave. Please be prepared to spent 4 hours with me. Why hire an inspector whose services merely meet Licensing and Certification minimum requirements which focus only upon protecting your contractual needs by identifying deficiencies and concerns? When for the same investment, you can participate in an LBI Education Inspection which in addition to providing you with a more comprehensive report, also teaches you all about the property, answers your questions, and provides a report created to serve as an informative manual similar to what is in the glove box of your vehicle.

Purchasing a home can be one of the biggest decisions you’ll ever make. We’re here to help. Our number one goal is to give our clients the knowledge and resources they need to be in the best position possible when it comes to buying or selling a home. Our inspectors are professionally trained beyond the state standards, ASHI Certified Inspectors (ACI) - the hardest certification to obtain that isn't a marketing gimmick, fully licensed and AHIT certified, utilizing the latest tools and technology to provide an excellent inspection service for every client, every time! Inspection reports include photos/videos of problems found along with helpful illustrations and are sent soon after the inspection. We’ve seen it all, from the best to the worst, so rest assured that you’ll find yourself in good hands with HomeKey Inspections. Book an inspection today and find out why we are one of the top-rated inspection companies in the area.

"I carefully read and compared company reviews and have had several home inspections over the years, so I expected a quality inspection from HomeKey but even going into it with high expectations I was still surprised and impressed with the thoroughness and conscientiousness of the inspection. My inspector was Mike, and the home is an older one owned by an elderly person so there were many issues to evaluate. The inspection took much longer than the average amount of time and the report was much longer and required much more work to produce, but there wasn't the slightest hint of rushing any of it or skimping at all. I myself suggested the roof could be skipped because I was worried moss had made it slippery and figured it was surely pretty much gone anyway, but Mike bravely went up there, made sure it was safe, then took a good long while in the heat and returned with photos and an issue that requires immediate attention. Likewise, I was surprised at the willingness to enter a very cramped dirt floor crawl space and proceed around the entire foundation... out of sight into the nether reaches... but I have photographic proof! Those are just two examples out of many, but from under the floors to over the ceilings in attic spaces accessible only through ceiling hatches, Mike examined every detail, took photos, and carefully documented the entire process which resulted in a long, thorough and informative report that will make the purchase decision better informed and provide structure for repair decisions. The price of the service was pretty much the going rate, and thus reasonable. I don't see much spread in the pricing of home inspections across companies, so I would feel cautious of any company that deviated by much. The difference in value for your cost would then be the quality of the inspection. Honestly, the cost of HomeKey's inspection could have been higher and would still have been well worth it for the care, time spent, the information provided, and for the assurance having a trained eye on things can give you."

Radon Detection and Reduction questions, answered by experts

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.
