Good Decisions 

Start with Insight

Purchasing a home is often one of the biggest financial investments in your life. We offer unbiased, 3rd party home inspections to assist our clients in making an informed decision when purchasing their home. We inspect condos, town homes, single family homes, multi-unit complexes, and small commercial buildings. Our reports are generated within 24 hours of the inspection because we understand how time sensitive and critical it is to have the report in order to make an informed and confident decision.

If you're experiencing high utility bills, hot/cold rooms, ice dams, poor air quality, drafts, poor air circulation, etc., we can help you. A Home Performance Audit will identify the source of those problems and the correct way to address them, before you spend thousands of dollars in inefficient contracting work. We provide contractors with an outlined action plan to assist them through renovations. We provide a complimentary audit after any renovations are completed to ensure the work was done correctly.

We assist builders, architects, and contractors with new construction, as well as consulting during construction to ensure that homes and commercial spaces are being built properly and efficiently.



Used to see how much air is leaking through the duct system specifically. Best to be done during rough-in before drywall is put up. 


Used to see how much air is leaking through the doors, windows, wall, etc. of the house.

We offer the following tests in addition to any service or as stand-alone testing:  Air quality, mold, VOC, Radon, formaldehyde, pest, and combustion safety. Your body’s reaction to poor air quality can often mimic cold symptoms such as a runny nose, itchy throat, watery eyes, headaches, sinus problems, allergies, or asthma. If you notice these symptoms are worse when you are in your home or office, have the air quality tested to pinpoint the source of the problem.

If you've purchased a new construction home within the last year, this inspection is for you. We assess your home from the outside in and form a report for the builders for you. Cover your assets before your warranty expires.

Want the most money for your home? Of course you do. With a Pre-Sale Walk Through we will help you determine what you need to address in order to get a higher price for your home, issues that a Home Inspector would find. By correcting these issues you can show buyers you are serious about selling and have made some improvements. 

Keeping up with the Joneses? Energy Efficient Homes are the future. A Home Energy Rating System (HERS) Rating is a requirement for many green building and energy efficient building standards across the country including ENERGY STAR for Homes.


A HERs Rating is also a requirement for an Energy Efficient Mortgage (EEM) and/or an Energy Improvement Mortgage (EIM).


Further, it can be a great way for builders and realtors to set their homes apart in a crowded real estate market.

Reports are crucial for our clients to have a detailed outline of the current condition of their home in order to make an informed and confident decision, whether buying or renovating. Insight Property Services understands how important this is, our inspectors generate the reports within 24 hrs (Home Inspection) to 48 hrs (Home Performance Audit) after the inspection. The report includes the pictures, breakdown of what is wrong with the construction, what needs remodeling, management, maintenance and more. 




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.
