Why Radon Testing is Critical for Baltimore Homes

Radon is an invisible, odorless radioactive gas that seeps into homes through foundation cracks, basement floors, and gaps around pipes. Baltimore is designated as an EPA Radon Zone 1 area, meaning homes have a high potential for elevated radon levels above 4.0 pCi/L.

Our certified inspector places continuous radon monitoring equipment in the lowest livable level of your home (typically basement or first floor). Strategic placement ensures accurate readings.
48-Hour Monitoring Period
The radon detector continuously measures radon gas levels over 48 hours. During this time, all windows and doors must remain closed (except for normal entry/exit).

After the testing period, we collect the equipment and analyze the data. Our professional-grade monitors provide precise measurements in picocuries per liter (pCi/L).
Receive Your Radon Report

When Should You Test for Radon?

🏡 Home Buyers & Real Estate Transactions

Radon testing is essential during the home buying process. Most purchase agreements include a radon contingency. If levels are above 4.0 pCi/L, buyers can negotiate for radon mitigation or price reduction. Testing during the inspection period protects your investment and your family's health.

🏠 Current Homeowners

If you've never had your home tested for radon, now is the time. The EPA recommends testing every 2 years and after any significant structural changes, basement renovations, or additions to your home.

🏗️ New Construction & Basement Remodels

Test new homes even if radon-resistant construction features were used. Before finishing a basement or converting it to living space, conduct a radon test to ensure safe radon levels.

🏘️ Selling Your Home

Maryland home sellers benefit from proactive radon testing. Having recent radon test results available shows transparency to buyers and can prevent last-minute negotiation surprises during closing.

Radon Testing is Required For:

FHA and VA loan approval (if property is in high-risk zone)
Most real estate purchase agreements in Maryland
Commercial property transactions
Rental properties in certain Maryland jurisdictions

Understanding Radon Levels & Health Risks

What is Radon? Radon is a naturally occurring radioactive gas created when uranium in soil, rock, and groundwater breaks down. It rises through the ground and enters homes through foundation cracks, gaps around pipes, sump pumps, and crawl spaces.

EPA Action Levels

Below 2.0 pCi/L: Low radon levels, minimal risk
2.0-4.0 pCi/L: Moderate levels, consider mitigation
4.0 pCi/L and above: EPA recommends radon mitigation system installation
Above 10 pCi/L: High risk, urgent mitigation needed

⚠️ Radon is the #2 cause of lung cancer in the United States

Long-term exposure to radon damages lung tissue. The radioactive particles settle in your lungs and continue to emit radiation, causing cellular damage that can lead to lung cancer. Risk increases significantly for smokers exposed to radon.

Radon Mitigation Options

If your radon test shows elevated levels, don't panic. Radon problems are fixable. A professionally installed radon mitigation system typically costs $800-$1,500 in Baltimore and can reduce radon levels by up to 99%. Most systems use sub-slab depressurization to vent radon gas safely outside.

Frequently Asked Questions About Radon Testing

How much does radon testing cost in Baltimore?

Professional radon testing in Baltimore costs $150 when added to a home inspection, or $175 as a standalone service. At Precision Home Inspections, we offer competitive radon testing pricing for both standalone tests and home inspection add-ons.

How long does a radon test take?

Professional radon testing requires a minimum 48-hour monitoring period with closed-house conditions. The inspector places the equipment on day 1, the device monitors continuously for 48 hours, then results are available within 24-48 hours after equipment retrieval.

Can I use a DIY radon test kit?

While DIY radon test kits are available at hardware stores for $15-$50, they are less accurate than professional continuous radon monitors. For real estate transactions, lenders and purchase agreements typically require professional radon testing by a certified inspector. DIY tests are prone to user error and may not meet real estate requirements.

Is radon testing required when buying a home in Maryland?

Maryland does not legally require radon testing for real estate transactions. However, the EPA and Maryland Department of Health strongly recommend radon testing before purchasing any home. Most real estate purchase agreements include a radon contingency allowing buyers to test for radon during the inspection period.

What happens if my radon test is high?

If your radon test shows levels at or above 4.0 pCi/L, the EPA recommends installing a radon mitigation system. For home buyers, this can be negotiated with the seller — either the seller installs mitigation before closing, or the purchase price is reduced to cover mitigation costs. Radon mitigation is effective and typically costs $800-$1,500 in Baltimore.

Does every home in Baltimore need radon testing?

Yes. Baltimore is in an EPA Radon Zone 1 area (high risk), and radon levels can vary dramatically between neighboring homes. The only way to know your home's radon level is through testing. Even newer homes with radon-resistant construction should be tested. The EPA recommends testing all homes below the third floor.

Can I live in my home during radon testing?

Yes, you can remain in your home during radon testing. However, you must maintain closed-house conditions — keep all windows and exterior doors closed except for normal entry and exit. Avoid opening windows, running whole-house fans, or using fireplaces during the 48-hour testing period to ensure accurate results.
