Pre-Sale Inspection Checklist for Denver Home Sellers

Thinking about listing your Denver home this season? The fastest way to reduce buyer surprises and protect your bottom line is to find issues before they do. If you know what to test and how to document it, you can price confidently and negotiate from strength. This guide gives you a Denver-focused pre-sale inspection checklist, local cost ranges, timelines, and tips to choose the right pros. Let’s dive in.

Why pre-sale inspections matter in Denver

Denver homes face a few unique risks that buyers ask about. Radon is common along the Front Range, and Denver sits in a high potential zone, so buyers expect test results and mitigation documentation. State and local agencies stress testing and mitigation as standard practice here. See guidance from the Colorado Department of Public Health and Environment and the City and County of Denver on radon testing and action steps.

Hail can be costly in our region, and major storms have produced widespread roof damage across metro neighborhoods. Buyers and insurers often want proof of roof condition or repair after storms. Seasonal freeze-thaw cycles also stress roofs, gutters, grading, and foundations, which can lead to moisture issues if not addressed.

What to inspect before you list

Use this checklist to order the right inspections in the right order. Tackle the general home inspection first, then add specialty tests based on age, location, and findings.

General home inspection

A pre-listing home inspection covers structure, roof, attic, HVAC, plumbing, electrical, grading, windows, and visible moisture. It helps you decide what to fix, disclose, or price around before buyers tour.

• Typical Denver cost: about $250 to $700 for most homes. Local averages for smaller homes often fall in the $288 to $440 range.
• Source for local costs: recent Denver pricing data.

Roof inspection

A roofer or roof-focused inspector checks shingles, flashing, hail impact, and remaining life. If your home was in a recent hail path, gather insurance claim papers and repair invoices.

• Why Denver: frequent hail events drive scrutiny of roof condition.
• Typical cost: about $100 to $300 for a standalone roof inspection.

Radon testing

A certified pro places a short-term device or continuous monitor for 48 to 96 hours and provides a report. Disclose results and any existing mitigation system.

• Why Denver: state and local agencies emphasize testing due to higher prevalence.
• Typical cost: professional test about $100 to $250.
• Mitigation: many systems run roughly $800 to $1,500 depending on foundation type. State and local programs outline testing and mitigation resources.
• Learn more: statewide guidance and Denver’s local radon page.

Sewer scope

A plumber runs a camera through the sewer lateral to check for roots, cracks, bellies, and offsets. Older Denver neighborhoods often have clay or cast-iron lines that warrant a look.

• Typical cost: usually $125 to $350 in Denver, within a broader national range up to $500.
• Cost reference: sewer camera inspection averages.

HVAC and chimney checks

Have an HVAC technician inspect and tune the furnace and AC, and provide service receipts. If you have a chimney or fireplace, a level-1 or level-2 inspection by a sweep can document condition.

• Typical cost: HVAC check about $100 to $200, chimney inspection about $100 to $200.
• Cost reference: Denver inspection price ranges.

Pest inspection

Order a wood-destroying insect inspection when required by a lender or when a home has extensive wood elements or prior activity. Keep any treatment warranties or repair records.

• Typical cost: often $50 to $200 depending on provider and scope.

Mold or moisture testing

If your inspector finds water stains or musty odors, targeted air or surface sampling can confirm concerns and inform remediation.

• Typical cost: roughly $300 to $450 for a basic inspection with a few samples.
• Cost reference: Denver mold inspection averages.

Lead and asbestos checks

For homes built before 1978, federal law requires lead-based paint disclosure and gives buyers the right to an inspection. Asbestos may be present in some older materials. Testing is optional pre-listing but can clarify scope and safety if you plan repairs.

• Typical cost: many lead XRF or asbestos sample sets run a few hundred dollars depending on scope.

Structural engineering review

If inspections show significant foundation movement or major cracks, bring in a licensed structural engineer. A clear report narrows negotiations and helps you compare repair bids to offering a buyer credit.

• Typical cost: simple evaluations can start in the low hundreds, and full engineered reports often range from $800 to $2,500 or more.

HOA, well, and septic documentation

If applicable, assemble HOA documents, known assessments, and any private well or septic records. Buyers often ask for these early in the process.

Colorado disclosures you should know

Colorado uses a Seller’s Property Disclosure that asks for your current actual knowledge. You must disclose adverse material facts you know about, which can include environmental hazards, past repairs, and permits. Give buyers copies of any pre-listing inspection and testing reports you order. Brokers also have a duty to disclose adverse material facts they know, so your listing team will encourage thorough, honest documentation.

Suggested timeline and workflow

• Step 0: Gather permits, receipts, warranties, service logs, insurance claim paperwork, and prior radon results. Organize HOA docs.
• Step 1: Order a general pre-listing home inspection. In busy seasons, book 2 to 3 weeks ahead. Use the report to prioritize next steps.
• Step 2: Order specialty tests based on findings and age. In Denver, prioritize a professional radon test, a roof inspection if the roof is 10 to 12 years old or hail is suspected, and a sewer scope for older homes or slow drains. Most can run concurrently.
• Step 3: If issues arise, get written bids, timelines, and warranties for repairs or mitigation. Decide whether to fix now or disclose and price accordingly. Keep all invoices and permits.
• Total window: about 2 to 6 weeks depending on scope and contractor schedules.

Use your results to negotiate

• Repair high-visibility, low-cost items to improve first impressions.
• For large-ticket items, consider disclosing clearly and offering a credit instead of repairing. Competitive bids help you set a fair number.
• Share inspection reports, receipts, and warranties with buyers. Transparent documentation often shortens negotiations and reduces re-inspection friction.
• For radon, include the mitigation report, contractor guarantee, and a recent post-mitigation test.

Choose qualified Denver pros

• General inspectors: look for membership in respected organizations and ask for sample reports, local references, and proof of E&O insurance. InterNACHI publishes standards and resources for inspectors.
• Radon measurement or mitigation: use NRPP or NRSB certified testers and DORA-licensed mitigation firms. Ask for calibration documentation or lab accreditation.
• Sewer scope: hire a plumber who provides a recorded video file and clear written findings.
• Roofing and hail work: choose roofers experienced with storm documentation and insurance claims. Ask for photos, material details, and workmanship warranties.
• Structural engineers: select a licensed PE with local foundation experience and request a written scope and estimate.
