If you’re planning to sell your home soon, here’s one truth every Denver seller learns quickly:

inspections can make or break your deal.

Buyers today come in well-researched, well-advised, and ready to dig into every inch of your home — and the inspection report becomes their roadmap. The cleaner that report looks, the smoother your closing goes. The messier it is, the more money and time you stand to lose.

The good news? Most of the biggest (and costliest) surprises are completely avoidable with a little prep.

Here are the top issues that blindsided sellers this year — and how to get ahead of them.

1. Sewer Line Problems

A sewer scope is one of the first things buyers order, and it’s also one of the priciest repairs when something pops up.

Common surprises:

• Root intrusion
• A belly or low spot
• Cracked clay tile
• Full replacements from house to city tap

Why this matters:

Sewer repairs can run anywhere from a few hundred to $20,000+. And if buyers see a major issue, they either want a full replacement or a massive credit… fast.

How to avoid it:

Get a sewer scope before listing. If it’s clean, amazing — you’ve just eliminated a huge inspection hurdle. If it’s not, you control the timeline and the bids.

2. Roof Damage

Between hailstorms and age, Colorado roofs take a beating.

Buyer inspectors often flag:

• Soft spots
• Missing shingles
• Granule loss
• Poor flashing
• Old swamp cooler penetrations

Why this matters:

Roof issues can spook buyers and insurers. A questionable roof may even delay closing if a new policy can’t be bound.

How to avoid it:

Order a roof inspection and, if needed, a certification from a licensed roofer. A clean roof cert is basically seller gold.

3. Electrical Panel & Wiring Issues

This has become a huge pain point, especially when previous work wasn’t permitted or done by a licensed electrician.

Common findings include:

• Double-tapped breakers
• Outdated or recalled panels
• Exposed wiring
• DIY work that wasn’t up to code

Why this matters:

Electrical issues scream “safety hazard,” and buyers rarely shrug those off. If a panel needs replacement, that’s a multi-thousand-dollar project… and it often turns into a negotiation circus.

How to avoid it:

If you’ve had electrical work done over the years, make sure the contractor was licensed and a permit was pulled. (Last week’s blog was exactly about this — because it can truly derail a sale.)

4. HVAC & Water Heater Problems

Mechanical systems tell the story of how the home has been maintained.

Issues inspectors love to note:

• Dirty furnace filters
• No proof of service
• Cracked heat exchangers
• Rusting or leaking water heaters

Why this matters:

Replacing systems is expensive. Buyers get nervous about anything nearing end-of-life even if it still works.

How to avoid it:

Have your HVAC serviced prior to listing and keep receipts. If your water heater is ancient, consider replacing it before the buyer even brings it up.

5. Radon (Yes, It’s Still a Big Deal)

Denver and the surrounding metro are notorious for high radon.

Why this matters:

If levels test high, buyers will request mitigation — usually $1,000–$1,600. Totally normal, but avoidable drama.

How to avoid it:

Order your own radon test ahead of time. If it’s high, you can install mitigation without dealing with inspection-day stress.

6. Crawlspace & Attic Surprises

Places sellers never look… inspectors always do.

Possible issues:

• Minor moisture
• Insulation gaps
• Evidence of past pests
• Ventilation issues

Why this matters:

These aren’t always big-ticket items, but they create a “maintenance concern” vibe that buyers cling onto.

How to avoid it:

Have someone pop their head in these spaces before listing. A handyman can fix 90% of what inspectors flag.

The Bottom Line

A smoother inspection = fewer negotiations, fewer credits, and fewer headaches.

When you tackle these items early:

• Your buyer feels confident
• Your contract stays stronger
• Your closing stays on track
• And you keep more money in your pocket
