HomeKey Inspections, LLC
HomeKey Inspections, LLC
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."
