The Ultimate Home Inspection Checklist for Des Moines Buyers

Don’t Skip the Most Important Step in Your Home Purchase

You’ve found the home. You’ve made the offer. The sellers have accepted. What happens next could save you tens of thousands of dollars — or prevent a purchase you would have deeply regretted.

The home inspection is the single most important due diligence step in any real estate transaction, and in the Des Moines market it carries particular significance. Central Iowa’s climate puts homes through extreme stress across four distinct seasons — sub-zero winters, spring flooding and freeze-thaw cycles, summer heat and severe storms, and autumn temperature swings that accelerate wear on roofing, foundations, and mechanical systems. Add an aging housing stock in many of Des Moines’ most desirable established neighborhoods, and the case for a thorough inspection becomes undeniable.

This guide gives Des Moines buyers a comprehensive, room-by-room inspection checklist along with practical guidance on choosing the right inspector, interpreting your report, and using inspection findings strategically in purchase negotiations. Whether you’re buying your first home, your fifth, or helping a senior loved one navigate a transition, this checklist is designed to make sure nothing gets missed.

From the Agent’s Desk: With over 10 years in property insurance before entering real estate, I’ve evaluated hundreds of properties for risk, damage, and insurability. I bring that same analytical lens to every home I help buyers evaluate — and I’ll often identify concerns that a standard inspection report flags but doesn’t fully contextualize. You deserve an agent who understands what those findings actually mean for your wallet and your insurance premiums.

Why a Home Inspection Matters in Des Moines

Des Moines is not a generic real estate market, and a home inspection here isn’t a generic exercise. The specific combination of Central Iowa’s climate, the age and construction styles of local housing stock, and Iowa’s building code environment creates a distinct set of inspection priorities that buyers — and even some inspectors from out of state — need to understand.

Weather Effects on Roofs and Exteriors

Iowa’s climate is genuinely demanding. Des Moines averages around 30 inches of snow per year and experiences some of the most dramatic freeze-thaw cycling of any major metro in the country. Winter ice dams form when heat escapes through poorly insulated attics, melting snow that refreezes at cold roof edges and forces water under shingles and into wall cavities. Spring snowmelt combined with heavy rain creates saturated soil conditions that test foundation drainage, sump pump capacity, and basement waterproofing systems.

Summer brings its own challenges. Central Iowa is in one of the highest hail frequency zones in the United States. Severe hail events have become more frequent in recent years, and many Des Moines area homes carry undetected or improperly repaired hail damage to roofing, gutters, siding, and HVAC equipment. Identifying hail damage before closing is critical — not just for negotiating repairs, but because undisclosed prior hail damage can complicate insurance claims and coverage after the sale.

Insurance Warning: Homes with hail damage that was patched rather than fully replaced may face claim denial or coverage limitations under a new homeowner’s policy. Ask your inspector specifically about evidence of hail impact and prior repair history on the roof and siding.

Common Issues in Older Des Moines Neighborhoods

Many of Des Moines’ most appealing neighborhoods — Beaverdale, Merle Hay, Drake, Sherman Hill, and the East Side — feature housing stock built between the 1920s and 1970s. These homes offer character, mature landscaping, and established community, but they come with age-specific concerns that require an experienced inspector’s eye:

• Knob-and-tube or aluminum wiring in pre-1970s homes that may not meet modern safety standards and can be difficult or expensive to insure.
• Original cast iron or galvanized steel drain lines that are approaching or past their service life and may require replacement or lining.
• Lead paint and asbestos-containing materials in homes built before 1978, requiring proper disclosure and potentially specialized remediation.
• Foundation issues ranging from settling and minor cracking to significant movement in homes built on expansive clay soils common throughout Polk County.
• Inadequate attic insulation and ventilation in homes that predate modern energy efficiency standards, resulting in elevated heating and cooling costs.
• Original single-pane windows with failed glazing and seals that reduce energy efficiency and can create condensation and moisture intrusion issues.

Local Building codes and Regulations

Iowa building codes are adopted and enforced at the local level, meaning requirements can vary between Des Moines, Ankeny, West Des Moines, Waukee, and other municipalities. Unpermitted additions, finished basements, deck constructions, and electrical or plumbing work are among the most common code compliance issues discovered during inspections.

Work completed without proper permits creates real problems for buyers: it may not meet current safety standards, it can complicate future insurance claims, it may need to be disclosed in future sales, and some lenders will require remediation before funding. A good inspector will flag areas that appear to be modified or improved without permits, and your agent should help you understand what remediation might cost before you remove contingencies.

Preparing for Your Home Inspection

Choosing a Qualified Inspector

Not all home inspectors are created equal, and in Iowa — which has relatively limited licensing requirements compared to some states — the range in quality and thoroughness can be significant. Choosing the right inspector is one of the most impactful decisions you’ll make in the homebuying process. Here’s how to do it well:

Verify Licenses and Credentials

Iowa home inspectors are licensed through the Iowa Department of Inspections, Appeals and Licensing. Always verify that your inspector holds a current Iowa license. Beyond state licensing, look for membership in professional organizations such as the American Society of Home Inspectors (ASHI) or the International Association of Certified Home Inspectors (InterNACHI), which require ongoing education and adherence to standards of practice that exceed the minimum state requirements.

For older homes or properties with specific concerns, consider inspectors with additional certifications in areas such as radon measurement, mold assessment, or structural evaluation. These specializations indicate both expertise and commitment to professional development.

Read Client Reviews and Request Referrals

Ask your real estate agent for referrals to inspectors they’ve seen produce thorough, accurate reports — not just inspectors who are fast and easy to work with. There’s an important distinction. Google reviews and Yelp listings can be useful, but agent referrals carry more weight because experienced agents have seen which inspectors’ findings hold up over time and which ones miss things.

Ask prospective inspectors for sample reports. A quality inspection report should be detailed, include photographs of every item flagged, clearly distinguish between safety issues, major defects, and minor maintenance items, and be written in plain language that a buyer without construction expertise can understand and act on.

Compare Fees and Service Inclusions

Standard home inspections in the Des Moines area typically range from $350 to $550 for an average-sized single-family home, with pricing influenced by square footage, age of the home, and the inspector’s experience level. Some inspectors offer packages that include radon testing, sewer scope, or thermal imaging at a bundled price — these add-ons are frequently worth the investment.

Recommended Add-Ons: In Des Moines, always add radon testing to your inspection (Iowa has elevated radon levels statewide) and strongly consider a sewer scope for any home over 30 years old. The combined cost of $150–$300 is trivial compared to the cost of a failed sewer line replacement, which can exceed $8,000–15,000 in the metro.

Creating Your Inspection Checklist

Before inspection day arrives, prepare yourself with a working understanding of the key areas that will be evaluated. This allows you to follow along meaningfully during the inspection, ask informed questions, and identify your own concerns before the inspector begins.

Key categories to have on your radar going in:

• Structural elements: Foundation, framing, load-bearing walls, and overall structural integrity of the home.
• Mechanical systems and appliances: Furnace, air conditioning, water heater, electrical panel, and included appliances.
• Safety components: Smoke detectors, carbon monoxide detectors, GFCI outlets in wet areas, handrail compliance, and egress windows in basement bedrooms.
• Exterior features: Roof, gutters, siding, grading and drainage, driveway condition, decks, patios, and outbuildings.

Detailed Home Inspection Checklist

The following checklist is organized by inspection area. Use this as a reference guide before and during your inspection — and bring it with you on inspection day so you can track what has been reviewed and note any questions for your inspector.

  EXTERIOR INSPECTION

  INTERIOR INSPECTION

  ATTIC & BASEMENT EVALUATION

Iowa Radon Alert: Iowa has one of the highest radon concentrations of any state in the country. The EPA action level is 4 pCi/L — Iowa homes frequently test above this threshold. Always include radon testing with your inspection. Mitigation systems typically cost $800–$1,500 and are highly effective, but this should be a negotiated seller cost when levels exceed the action level.

Post-Inspection: Next Steps for Des Moines Buyers

Reviewing the Inspection Report

A thorough home inspection report can run 40 to 80 pages for a typical Des Moines area home, and its length alone can feel overwhelming. Here’s how to approach it strategically rather than reactively:

• Read the summary section first. Most inspectors provide an executive summary of the most significant findings. This gives you the landscape before you dive into details.
• Categorize findings by severity. Issues generally fall into three buckets: safety hazards requiring immediate attention, major defects that affect the home’s function or value, and routine maintenance items that are normal for a home of that age. Focus your negotiation energy on the first two categories.
• Look for patterns. A single crack in drywall is minor. Cracks throughout multiple rooms following consistent patterns may indicate foundation movement. Multiple moisture stains in different locations may indicate a systemic drainage problem rather than isolated incidents. Patterns tell a story.
• Get contractor estimates before negotiating. For any major item you intend to request repair credit for, have a qualified contractor provide a written estimate. This transforms your request from subjective to factual and strengthens your negotiating position.

Report Review Tip: Bring your inspection report to your final walk-through before closing and verify that all negotiated repairs were completed as agreed. Request receipts and any applicable permits or warranties for work performed.

Negotiating Repairs or Credits

The inspection report is not just a disclosure document — it’s a negotiating tool. In the Des Moines market, how you use it depends on current market conditions, the home’s pricing, and the nature of the findings.

General negotiation principles that hold up well in the Des Moines market:

• Prioritize safety and major structural or mechanical issues over cosmetic items. Sellers are far more likely to respond reasonably to requests for essential repairs than to a long list of minor maintenance items.
• Request a credit toward closing costs or purchase price reduction rather than seller-completed repairs for significant items whenever possible. This gives you control over the quality of the work and the contractor selected.
• Be realistic about the age of the home. Requesting that every imperfection in a 1950s bungalow be corrected to new-construction standards will derail negotiations. Focus on material defects, not normal wear and aging.
• Use the inspection period to re-evaluate your offer price if findings are significant. In some cases, the appropriate response to major discoveries is not a repair request but a price adjustment that reflects the home’s true as-is condition.

Negotiation Insight: As your agent, I help you interpret which findings carry real financial weight and which are standard for the age and type of home you’re purchasing. My insurance background gives me an additional lens — I can tell you which items are also likely to affect your insurance premiums or coverage, which changes the calculus on what’s worth fighting for.

Planning Maintenance and Upkeep

A great home inspection doesn’t end your work — it begins it. Use the report as the foundation for a proactive maintenance plan tailored to Central Iowa’s climate demands. Key seasonal maintenance priorities for Des Moines area homeowners:

Fall Preparation (September – October)

• Service furnace and replace filter before first heating use of the season.
• Clean gutters after leaves fall and verify downspout extensions are in place.
• Disconnect and drain exterior hose bibs and shut off irrigation systems before first freeze.
• Inspect roof and flashing for any storm damage from summer hail or wind events.
• Caulk and weatherstrip exterior doors and windows to reduce heating costs.

Winter Monitoring (November – February)

• Monitor attic temperatures to prevent ice dam formation — adequate insulation and ventilation are your primary defenses.
• Keep garage temperatures above freezing to protect pipes on shared walls.
• Test sump pump operation periodically and ensure backup battery is charged before spring thaw.
• Check basement walls and floor-wall joints after significant snowmelt or rain events.

Spring Action (March – May)

• Inspect roof and gutters after winter for hail damage, ice dam impact, or displaced shingles.
• Walk the foundation perimeter after frost leaves the ground — new cracks or movement may appear.
• Schedule AC service before summer demand peaks.
• Check grading and drainage before heavy spring rains to confirm water flows away from foundation.

Summer Readiness (June – August)

• Trim trees and shrubs away from the roofline and foundation to reduce moisture and pest risk.
• Inspect deck hardware and boards after winter — Iowa’s freeze-thaw cycles loosen fasteners over time.
• Check window and door seals for any air infiltration that will stress your cooling system.
• Ensure dryer vent is clear — lint buildup is a significant fire risk and reduces appliance efficiency.

Conclusion: Knowledge Is Your Best Protection

The home inspection is where buyers shift from hoping a home is what it appears to be to knowing what they’re actually purchasing. In the Des Moines market — where Central Iowa’s climate, aging housing stock, and evolving building standards create a genuinely complex inspection environment — going into that process prepared, informed, and represented by the right people makes a real difference.

Use this checklist as your guide. Take it to the inspection. Ask questions. Read the full report. And work with an agent who understands not just the real estate transaction but the physical condition of the home you’re buying and what that condition means for your budget, your insurance, and your long-term ownership experience.
