Radon System Service and Repair in Michigan

A radon mitigation system operates continuously to help reduce the amount of radon entering a building. Over time, the fan, piping, seals, pressure indicator, or other components may need professional attention.

Elevate Radon Defense provides radon system service and repair for homes and businesses throughout Macomb, Oakland, Washtenaw, and Wayne counties. We evaluate existing equipment, explain apparent concerns, and recommend an appropriate next step based on the system and property.

Keep Your Radon Reduction System Working as Intended

Installing a mitigation system is not the end of radon management. The equipment should be observed, tested, and serviced when signs of damage or reduced performance appear.

The EPA advises property owners to check their system warning device regularly and retest at least every two years. Like other mechanical equipment, a radon system may require occasional maintenance or component replacement.

A fan that sounds normal does not confirm that the indoor radon concentration remains low. Only a new radon measurement can show the current level inside the property.

Signs Your Radon System May Need Service

• The radon fan has stopped running
• The fan has become louder than usual
• The pressure indicator has changed significantly
• Both sides of the manometer show the same level
• Piping is cracked, separated, or damaged
• Seals around foundation openings have deteriorated
• A sump cover is loose, cracked, or no longer sealed
• The system warning device has activated
• Water or condensation has collected in the piping
• Exterior components have been damaged by weather

What Does the Pressure Indicator Tell You?

Many active systems include a U-shaped pressure gauge called a manometer. Different liquid levels on each side generally show that the fan is creating pressure within the system.

A manometer does not measure indoor radon. It only provides information about system pressure, so a normal-looking gauge cannot replace periodic testing.

Property owners should learn what the gauge looked like when the system was operating properly. A major change from the original reading may indicate that professional evaluation is needed.

Our Radon System Evaluation Process

1. Discuss the System History

We begin by asking about the age of the system, previous test results, past repairs, and any recent changes. We also ask what warning signs or performance concerns led you to request service. Original installation records can be helpful but are not required. Our team can evaluate systems installed by another company.

2. Review Accessible Components

We examine accessible piping, connections, seals, fan components, system indicators, and other visible parts. We also consider whether renovations, foundation changes, or property damage may have affected the installation. The inspection focuses on identifying apparent defects and conditions that may interfere with normal operation.

3. Explain the Findings

We explain what we observed and why it may matter. Our goal is to give you clear information rather than a list of technical terms without context. Depending on the findings, we may recommend repair, component replacement, testing, further diagnostic work, or monitoring.

4. Complete the Approved Repair

Once the appropriate work is understood, we complete the approved system repairs within the confirmed scope. This may involve correcting damaged components, improving seals, replacing failed equipment, or addressing other accessible concerns. The exact repair depends on the system design and condition.

5. Recommend Follow-Up Testing

Testing after a system alteration or repair helps determine the current indoor radon concentration. Recognized guidance also calls for retesting when a mitigation system has been modified or repaired. A successful mechanical repair does not provide a radon result by itself. The completed test supplies the information needed to evaluate indoor conditions.

Common Radon System Repairs

Radon reduction systems contain several components that work together. A problem with one component may affect performance, create noise, or allow soil gas to enter the building.

Service needs may include:



• Fan evaluation or replacement
• Damaged pipe repair
• Loose fitting correction
• Foundation penetration resealing
• Sump cover sealing
• Manometer or warning-device service
• Condensation or drainage correction
• Exterior pipe support repair
• System label or documentation updates
• Evaluation after remodeling or construction

Service After Renovations or Property Changes

Construction work can affect an existing mitigation system even when the equipment is not intentionally removed. Finished basements, new additions, sump changes, foundation repairs, and HVAC modifications can alter building pressure or the pathways through which soil gas moves.

Testing and system evaluation should be considered after major building changes. ANSI/AARST guidance identifies system repairs, alterations, foundation changes, ventilation changes, and newly occupied ground-contact spaces as reasons to perform additional testing.

Contact us before covering accessible system components during a renovation. Early coordination can help prevent avoidable damage and preserve access for future service.

Residential and Commercial System Support

Residential systems may serve basements, slabs, crawl spaces, additions, or several connected foundation areas. Homeowners may need service after purchasing a property with an unfamiliar system or noticing a change in the fan or gauge.

Commercial and multifamily systems can involve larger footprints, multiple devices, several suction zones, or formal operation and maintenance responsibilities. These properties may require a broader review based on the building design and occupancy.

Elevate Radon Defense works with homeowners, buyers, sellers, landlords, business owners, and property managers. We tailor the evaluation to the property rather than applying the same repair recommendation to every system.
