We’re going to be blunt: skipping the home inspection is the worst decision you can make as a buyer in the western suburbs. We don’t care how competitive the market is. We don’t care if the seller says “as-is.” A $400 to $600 inspection can save you $20K to $50K in surprise repairs.

Here’s what your inspector should be looking for — and what we’ve learned to watch for specifically in western suburb homes.

The Big-Ticket Items

Foundation. This is the one that scares everyone, and for good reason. Foundation repairs can run $10K to $30K+. In the western suburbs, we see foundation issues most often in older homes built before the 1970s, particularly in areas with clay-heavy soil. Horizontal cracks in basement walls are the red flag — they indicate lateral pressure that’s not going to fix itself.

Roof. A roof replacement on a typical suburban home runs $12K to $25K. Your inspector should tell you the approximate age and remaining life. If it’s got 3-5 years left, that’s a negotiation point, not a dealbreaker. If it’s actively leaking, that’s a different conversation.

HVAC. Furnace and AC replacements run $8K to $15K for a mid-size suburban home. Systems older than 15-20 years are living on borrowed time. We’ve seen plenty of homes in Hinsdale and Naperville where the sellers replaced the kitchen but left the 22-year-old furnace. Ask about it specifically.

The Western Suburbs Specific Stuff

Flood risk in Downers Grove. Look, we love Downers Grove. It’s one of our favorite markets. But parts of it — particularly near St. Joseph Creek — have documented flood risk. If you’re buying in DG, check the FEMA flood map for your specific address. Homes in flood zones require flood insurance, which can add $1,000 to $3,000 per year to your costs. Your inspector won’t check this, so you need to do it yourself.

Sewer issues in older areas. Many pre-1970s homes in the western suburbs still have clay sewer pipes connecting to the main line. These deteriorate over time and can cost $5K to $15K to replace. We’d recommend a sewer scope (a camera inspection of the line) for any home older than 40 years. It’s an extra $200 to $350 and it’s worth every penny.

Radon. Illinois has naturally elevated radon levels, and the western suburbs aren’t exempt. Your inspector should include radon testing, or you should add it separately. Radon mitigation systems are straightforward and run $800 to $1,500 — but you want to know before you close, not after.

What to Do With the Results

Here’s the thing that first-time buyers often misunderstand: the inspection report isn’t a reason to panic. Every home has issues. A 20-year-old home will have a list of items. That’s normal.

What we help our buyers do is separate the deal-relevant issues from the maintenance stuff. A cracked foundation? That’s a negotiation. A dripping faucet? That’s a Saturday project. Don’t walk away from a great home because the inspection found $2,000 worth of minor repairs.

The smart move is to use significant findings — roof, HVAC, foundation, sewer — as leverage for a price credit or repair agreement. We’ve negotiated $5K to $25K in credits for our buyers based on inspection findings. The inspection pays for itself many times over.
