Good Decisions 

Start with Insight




Insight Property Services is a veteran owned small business in Naperville, IL providing superior home inspection services and third party, unbiased building consulting to home owners and building professionals throughout the Chicagoland area.

We are not your traditional home inspectors. We know people need advice about their homes and properties even more after they buy, as they continue to invest thousands more than the purchase price in maintaining, repairing, and upgrading the property. As building consultants, we are here to provide follow-on guidance and resources to our clients, throughout their homeownership.

Need to replace your water heater? Experiencing air quality/respiratory issues? Want to remodel your kitchen or bathroom? We are here to help guide you toward opportunities and best practices, and away from pitfalls.

We help property owners identify the underlying cause of issues in their homes, before the renovation process begins. We provide an improvement 'road map', eliminating guesswork and streamlining your home renovation process, while considering issues such as fresh air exchange, ventilation, and air quality.  


Insight does not provide contracting services, as we believe doing so could lead to a conflict of interest. However, we can and often do recommend contractors in your area that we know to provide quality work, and who are committed to the proper application of building science principles. Just email us or check out our Affiliate page. Whichever contractor you use, remember to have Insight's consultants return and retest your home after the work is completed. We use diagnostic testing to ensure the quality of the work, ideally before the contractors leave - saving everyone time, money, and frustration. 

If you are buying, selling, building, or improving a home, good and timely advice is key to making good decisions - especially when thousands of dollars are on the line. Insight can alert you to opportunities to take advantage of, and to issues that should be avoided. Even experienced contractors consult with us when they come across issues they've not seen before.


We have been providing superior quality Home Inspections, small Commercial Building Inspections, Home Performance Testing & Energy Audits, Air Quality Testing, Energy Star Home certifications, and Professional Contractor Training since 2009.

Joe Konopacki has a gift to teach and inspire! I did not know much about the process as a new home buyer and he used analogies and humor to educate me on the finer points of my new home. He took his time and found parts of the home that I don’t know if the seller knew was there! The patience and time he took to explain various concepts was worth every penny! He didn’t leave a part of the house untouched as he even made sure all the appliances worked properly. The report was done quickly and with pictures to show issues that came up during the inspection. I could not have asked for a better experience and the home inspection was the LEAST stressful part of the entire experience. Joe and Bill did a phenomenal job! I highly recommend Insight! I’ve already recommended them twice!
