Upgrading and maintaining your radon system ensures continuous protection for your family. Over time, equipment can lose efficiency, but with regular care, the system keeps harmful radon levels under control, providing ongoing safety and healthier indoor air quality.
Extended System Lifespan
Routine maintenance and timely upgrades add years to the lifespan of your radon mitigation system. Preventing wear and replacing outdated parts helps avoid complete system failure, keeping your investment performing efficiently while minimizing unnecessary future replacement costs.
Compliance with Current Standards

FREQUENTLY ASKED QUESTIONS
Why is sealing my sump pit important?
An unsealed sump pit can allow radon gas, moisture, foul odors, and pests to enter living areas. Professional sealing creates an airtight barrier that still allows sump pump access, protecting your home’s air quality, structure, and occupants from hidden environmental hazards.
Will sealing affect sump pump performance?
No. We use specially engineered covers with removable access panels, allowing maintenance, repair, or pump replacement without disturbing the seal. This ensures your sump pump operates efficiently while maintaining the protective barrier against radon, moisture, odors, and pests year-round for continuous home safety.
Can sump pit sealing reduce radon levels?
Yes. Sump pits are often major radon entry points. Sealing them eliminates a direct infiltration pathway, helping lower radon concentrations in conjunction with mitigation systems. This combined approach ensures safer indoor air quality and provides an essential layer of protection against long-term radon exposure.
How often should seals be inspected?
We recommend annual inspections to confirm seals remain intact and effective. Natural wear, material degradation, or foundation settling can compromise sealing over time. Routine checks help identify potential issues early, ensuring ongoing protection against radon, moisture, pests, and odors without unexpected performance failures.
Does drain sealing stop water flow in emergencies?
No. Our sealing techniques preserve a drain’s ability to function during water emergencies, such as flooding, while blocking gases, pests, and odors under normal conditions. This ensures both safety and utility, keeping your home protected without sacrificing essential drainage performance capabilities.
Is sealing part of a radon mitigation system?
Yes. Sump pit and drain sealing is often a vital component of a complete radon mitigation plan. When combined with other systems, it enhances overall effectiveness, reducing radon infiltration and improving the home’s defense against multiple environmental hazards simultaneously.
Can I seal my sump pit myself?
While DIY kits exist, professional sealing ensures high-quality materials, precision installation, and compliance with radon mitigation best practices. Experts also identify additional vulnerabilities you might miss, ensuring a more comprehensive, long-lasting solution that protects air quality and structural integrity effectively.
Will sealing improve my home’s air quality?
Yes. Sealing sump pits and drains blocks radon gas, excess moisture, odors, and pest infiltration. This leads to cleaner, healthier indoor air, reduced allergens, and a lower risk of respiratory problems, benefiting both immediate comfort and long-term occupant health.
