Radon Gas Removal, Remediation, and Services in Halifax: A Comprehensive Guide

Radon gas is a colorless, odorless radioactive gas that can infiltrate homes and buildings, posing serious health risks. According to health experts, prolonged exposure to radon can increase the risk of lung cancer, making it a silent but dangerous threat to homeowners. In Halifax, like many other areas, radon levels can be higher than expected, particularly in older homes, and it’s important for residents to be aware of the risks and available radon services. This guide will walk you through what radon is, how it enters your home, why it’s a problem, and the steps you can take for radon gas removal and remediation in Halifax.

What Is Radon Gas?

Radon is a naturally occurring radioactive gas that is produced by the decay of uranium in the soil, rock, and water beneath your home. It typically enters homes through cracks in the foundation, gaps around windows and doors, and other openings in the structure. Since radon is colorless and odorless, it is impossible to detect without specialized equipment.

According to Health Canada, radon is the second leading cause of lung cancer after smoking, and it is estimated that radon exposure is responsible for 16% of lung cancer deaths in Canada. The only way to determine if radon is present in your home is through testing, and the only way to remove it is through a remediation process.

Why Is Radon a Concern in Halifax?

Halifax, situated in the province of Nova Scotia, is not immune to radon exposure. In fact, certain areas of Halifax and surrounding regions have been found to have elevated radon levels due to the underlying geology, which may have higher uranium concentrations in the soil. This means that homeowners in these areas may be at increased risk.

The high moisture levels in Halifax’s coastal climate can also contribute to radon problems, as radon tends to accumulate more easily in damp and poorly ventilated areas. Homes built with a foundation that has cracks or gaps are particularly vulnerable to radon infiltration.

Radon levels can vary even within a single neighborhood, making it essential for homeowners to have their properties tested, regardless of the age or condition of the Residential Radon Removal Halifax. Even new homes can have elevated radon levels if the construction materials or the foundation have created pathways for radon gas to enter.

How Does Radon Enter a Home?

Radon gas enters buildings primarily through the ground. The gas rises from the soil or rock below the house and can seep in through the following routes:

Cracks in the foundation: Even small cracks can allow radon to seep through.

Unsealed joints: Any gaps around floor drains, sumps, or joints between walls and floors can let radon into your home.

Openings around pipes: Areas where plumbing and electrical pipes enter the house may provide a pathway for radon to enter.

Dirt floors: If your basement or crawl space has a dirt floor, this increases the potential for radon to infiltrate your home.

While the gas is most commonly found in basements and lower levels of homes, it can also move upward to other parts of the house. This is why radon testing and remediation should be a concern for any part of the home, not just the basement.

Testing for Radon in Halifax

The first step in addressing a radon problem is testing. There are two main types of radon testing:

Short-term Radon Testing

Short-term testing is typically done using charcoal canisters, alpha-track detectors, or electronic monitors, which are left in place for a period of 2-7 days. This type of test provides a quick snapshot of radon levels, but it may not give an accurate reading of the long-term exposure risks.

Long-term Radon Testing

Long-term testing uses devices that remain in place for 90 days to one year. This provides a more accurate measure of radon levels over time, as radon levels can fluctuate due to changes in weather, ventilation, and other factors. Health Canada recommends using long-term tests to get a better understanding of the potential risk.

Testing is crucial, as radon levels can vary significantly from one home to the next. Even two homes in the same neighborhood might have drastically different radon levels, which is why personal testing is the only way to ensure the safety of your home.

What Are Acceptable Radon Levels?

According to Health Canada, the acceptable radon level in a home is less than 200 becquerels per cubic meter (Bq/m³). However, any radon level above 100 Bq/m³ is considered elevated, and homeowners are encouraged to take steps to reduce radon levels as much as possible.

If your home’s radon level is found to be higher than the recommended limit, it is time to look into radon gas removal and remediation services.

Radon Gas Removal and Remediation in Halifax

Once radon levels in your home have been tested and found to be high, remediation is the next step. Radon remediation refers to the process of removing or reducing radon gas levels to safe levels. The methods for remediation depend on the specifics of the home, but in general, they involve increasing ventilation or sealing the pathways through which radon enters the building.

Here are some of the most common radon remediation techniques used in Halifax:

1. Active Soil Depressurization (ASD)

This is the most common and effective method of radon remediation. It involves installing a vent pipe system and fan that draws radon from beneath the house and vents it outside. This system is typically installed in the basement or crawl space, where radon is most likely to accumulate. The fan helps create a negative pressure below the house, which prevents radon from entering.

2. Sealing Cracks and Openings

Sealing cracks in the foundation, walls, and floors can reduce the pathways through which radon enters the home. While sealing alone will not remove all radon from a home, it can significantly reduce radon levels when combined with other remediation methods, like ASD.

3. Sub-membrane Depressurization (SMD)

For homes with dirt floors in the basement or crawl spaces, sub-membrane depressurization can be an effective solution. This method involves laying a plastic sheet over the dirt floor and creating a venting system to draw radon gas away from the space. This system is often used when active soil depressurization isn’t practical due to the home’s design.

4. Increasing Ventilation

In some cases, improving the ventilation in your basement or lower levels can help to reduce radon concentrations. This may involve installing a ventilation system or increasing the number of air exchanges in the home to dilute radon levels.

5. Heat Recovery Ventilation (HRV)

In homes with poor ventilation, installing an HRV system can help improve air circulation while also reducing radon levels. These systems exchange stale indoor air with fresh outdoor air while conserving energy.

Finding Radon Remediation Services in Halifax

If you’ve determined that radon levels are elevated in your home, you’ll need a professional radon mitigation company to help with the remediation process. In Halifax, there are several radon mitigation specialists who can assist with the removal and reduction of radon gas in your home.

When searching for a radon remediation professional, consider the following:

Certification: Look for professionals who are certified by national or provincial radon Radon Gas Testing Halifax, such as the Canadian National Radon Proficiency Program (C-NRPP). This ensures they have the necessary training and expertise.

Experience: Choose a company with experience in radon remediation and a proven track record of successful radon removal projects.

Free Consultation: A reputable company should offer a free consultation to assess your home and determine the best approach for remediation.

Warranty: Many companies provide a warranty on their radon mitigation systems, giving you peace of mind that the solution will be effective long-term.

Final Thoughts
