Colorado homeowners and buyers are becoming increasingly aware of a critical health risk hiding beneath their homes: radon gas. Radon is a naturally occurring radioactive gas that seeps into homes through cracks in the foundation, slabs, crawlspaces, and plumbing penetrations. It's colorless, odorless, and tasteless—making it undetectable without proper testing.

Why does this matter in Colorado? Because our entire state lies within EPA Radon Zone 1, meaning we have some of the highest average indoor radon levels in the U.S. In fact, more than 50% of homes in Colorado test above the EPA's recommended action level of 4.0 pCi/L.

In this article, we’re diving into the importance of radon testing and mitigation during home inspections in Colorado. Whether you're buying, selling, or maintaining a property, here's what you need to know.

Why Radon Is a Serious Concern in Colorado

• High Elevation + Geology = High Risk: Colorado's geology makes it a hotspot for radon release. Because of our elevation and soil composition, radon gas escapes more easily and accumulates in homes at unsafe levels.

• Lung Cancer Risk: Radon is the second leading cause of lung cancer in the U.S., following smoking. Long-term exposure—even to moderately elevated levels—can significantly increase health risks.

• Widespread Presence: The Colorado Department of Public Health and Environment (CDPHE) has found that radon levels average around 6.3 pCi/L across the state, well above national averages.

Radon and Colorado Real Estate Law

Recent legislation in Colorado has made radon testing and disclosure more important than ever:

• HB21-1195: As of 2022, radon measurement and mitigation professionals in Colorado must be licensed through the Department of Regulatory Agencies (DORA). This law ensures that only trained, certified professionals can legally test or mitigate radon in residential properties.

• SB23-206: Effective August 2023, this bill requires sellers and landlords to disclose any known radon testing results, mitigation systems, and potential risks. It also requires them to provide educational materials to buyers and tenants.

What does this mean for homebuyers?

• Always request radon test results during the inspection process.

• If results are unavailable, consider testing as part of your due diligence.

• If radon levels exceed 4.0 pCi/L, negotiate for mitigation before closing.

For sellers:

• Be prepared to disclose any known radon test results.

• If mitigation systems are in place, ensure they’re documented and functioning.

What Radon Testing Involves

Short-Term vs. Long-Term Testing

• Short-term tests (2–7 days) are commonly used during real estate transactions.

• Long-term tests (90 days or more) provide a more accurate picture of year-round exposure.

Certified inspectors typically use continuous radon monitors (CRMs), charcoal canisters, or alpha-track detectors.

Where to Test

Testing should occur in the lowest level of the home that is regularly used—often basements or ground-level living areas.

What to Do If Radon Levels Are High

If your radon test results come back at or above 4.0 pCi/L, it’s time to take action.

Common Mitigation Techniques

1. Sub-Slab Depressurization: The most common system. A pipe is inserted through the basement floor and connected to a fan that vents radon gas outside the home.

2. Sump Pit Suction: For homes with sump pumps, this system can draw radon from beneath the slab through the sump basin.

3. Crawlspace Ventilation: Installing a vapor barrier and using fans to vent gas from crawlspaces.

Costs

• Radon mitigation typically costs between $800–$1,500, depending on the size of the home and system complexity.

• Annual maintenance costs are minimal, often under $150.

Post-Mitigation Testing

Once a system is installed, retesting is essential to confirm effectiveness. The EPA recommends retesting every two years to ensure ongoing safety.

Common Questions About Radon in Colorado

Is radon testing required by law in Colorado? No, testing itself is not legally required for every home sale. However, disclosure is required if radon testing has been conducted and results are known.

What is a safe radon level? The EPA recommends mitigation if levels are at or above 4.0 pCi/L. Ideal levels are under 2.0 pCi/L.

Can new homes have high radon levels? Yes. Even homes built with passive radon systems can still have elevated levels. Testing is necessary regardless of age, style, or location.

How often should I test for radon? Every 2 years, or after major renovations that affect the foundation or ventilation.

Will a mitigation system affect home value? Not negatively. In fact, buyers often see a radon mitigation system as a value-add, knowing the home is already protected.

Why Every Home Inspection in Colorado Should Include Radon Testing

Radon isn’t just another box to check—it’s a health and safety issue that impacts every homeowner and future occupant. Because Colorado has such high levels statewide, every home inspection should include a radon test.

Including radon testing during inspections:

• Protects buyers from unknown health risks.

• Helps sellers avoid future liability.

• Ensures transparency in every real estate transaction.

The Denver housing market is entering 2025 with significant opportunities and challenges for buyers. Whether you’re a first-time homebuyer or a seasoned investor, understanding the market dynamics and the importance of home inspections can give you a competitive edge. Here, we’ll explore the latest trends in Denver’s real estate market and dive into how home inspections are evolving to meet modern demands.

Denver Housing Market Trends for 2025

As of January 2025, the Denver housing market remains active, albeit with some notable changes:

• Home Value Adjustments: Home values in Denver are expected to see a slight decrease of approximately 0.8% by mid-2025. This adjustment comes after years of rapid appreciation, offering buyers a chance to enter the market at more favorable prices.

• Price Reductions: Around 50% of homes sold in late 2024 experienced at least one price reduction before closing. For buyers, this indicates increased opportunities to negotiate and find better deals.

• Market Activity: Despite a cooling trend in some areas, Denver’s real estate market remains competitive, with homes spending an average of 30 to 40 days on the market. Buyers should be prepared to act quickly when they find the right property.

Why Home Inspections Matter More Than Ever

A comprehensive home inspection has always been a cornerstone of the buying process, but its importance is heightened in 2025 due to evolving buyer expectations and technological advancements. Here are key reasons why home inspections are essential:

Advanced Inspection Technologies

Modern home inspections now include tools like drones and thermal imaging. These advancements allow inspectors to assess hard-to-reach areas, such as rooftops, and detect hidden issues like moisture leaks or insulation gaps. For buyers, this means a more thorough understanding of a property’s condition before making a commitment.

Specialized Inspections

As homes become more complex, the demand for specialized inspections is rising. In Denver, buyers are increasingly requesting:

• Radon Testing: Given Colorado’s high radon levels, this test is a must to ensure a safe living environment.

• Energy Audits: With a focus on sustainability, energy audits help buyers understand a home’s efficiency and potential savings.

• Smart Home Assessments: As smart technology becomes more common, inspectors are evaluating the functionality and reliability of these systems.

Inspection Contingencies

Most buyers include an inspection contingency in their offers, which allows them to renegotiate or withdraw if significant issues are found. This clause is especially critical in a market where hidden maintenance concerns can lead to unexpected costs.

Tips for Buyers in 2025

To navigate the Denver market successfully, buyers should consider the following:

1. Prioritize Home Inspections Never skip a home inspection, even in a competitive market. A thorough report can uncover critical issues and save you thousands of dollars in the long run.

2. Consider Pre-Inspections Conducting a pre-inspection before submitting an offer can give you a competitive edge. Sellers may view this as a sign of serious intent, potentially strengthening your negotiation position.

3. Budget for Repairs Be prepared to allocate funds for necessary repairs or updates. This is especially important in Denver’s older neighborhoods, where homes may require structural or aesthetic improvements.

4. Work with Certified Inspectors Choose inspectors with certifications and experience relevant to Denver’s market. Ask for references and reviews to ensure you’re working with a trusted professional.

The Role of Negotiation in 2025

With price reductions becoming more common, buyers have room to negotiate—not just on price, but also on repairs and seller concessions. Use the home inspection report as leverage to request fixes or credits that align with the property’s condition. Sellers are often more willing to negotiate in a cooling market to ensure a smooth transaction.

The Denver housing market in 2025 offers opportunities for savvy buyers who come prepared. By prioritizing a comprehensive home inspection, leveraging advanced technologies, and understanding market trends, you can make informed decisions that protect your investment and your peace of mind.

Whether you’re buying your dream home or adding to your real estate portfolio, staying informed and proactive is the key to success in Denver’s ever-evolving market.

Visually inspecting your roof will help you spot missing, cupped, or cracked shingles. Your roof’s structure and your home’s interior become vulnerable to water damage when you have missing shingles. Therefore, it is best to replace torn or missing shingles as soon as possible. If left unaddressed, the gutters, flashing, ventilation pipes, and chimney may eventually be damaged.
