RADON MITIGATION FAQ

Radon Mitigation Cost
The cost to install a radon mitigation system varies mainly based on the
complexity of the construction of the building. Generally, newer homes with
modern building codes are easier to mitigate. Our standard system averages $1500
for a complete single port install which includes all electrical &
post-mitigation testing. Homes built before the 90’s may require additional
suction ports and require larger fans. Please call to discuss an exact estimate
for your project.
While comparing estimates with other companies. Please note we use all schedule
40 hard-wall piping, and stainless steel hardware, with complete the electrical
connections.
What maintenance is required?
We design our systems to be maintenance-free and the only thing that will need
replacement is the motor about every 10+ years. We have seen motors last 20
years or more but when they do fail, a new one can be installed for around $400.
Our systems use all quality parts and stainless steel fasteners to ensure the
longevity of system integrity.
How much does it cost to run a radon system?
Using an average cost of $0.13/kilowatt, the average radon motor will cost $3
per month to operate 24 hours a day.
How long will the system need to run?
Generally, we install intend to leave the motor running all the time but in
certain situations, we can install a programmable timer. Limiting the motor use
could provide benefits to longevity and noise control but should only be used in
certain situations.
How long does installation take?
Most of the installs take around 4-6 hours and can be completed in one day. In
basements with multiple levels or crawlspaces, it could take multiple days
depending on complexity.
How long does installation take?
Most of the installs take around 4-6 hours and can be completed in one day. In
basements with multiple levels or crawlspaces, it could take multiple days
depending on complexity.
What are other benefits of radon systems?
The overall air quality of the home and basement should improve after a system
is installed. Manufacturers indicate up to 2 gallons of water vapor per day can
be pulled from the soil which reduces the overall humidity of the home. We have
also found buried building materials and other problems producing odors / VOC’s
which the system does a great job removing before reaching indoor air.

TYPES OF RADON MITIGATION SYSTEMS

Sub-Slab Depressurization (SSD)

Sub-slab depressurization works by creating a pressure differential between the
soil beneath a building’s foundation and the indoor environment. This technique
involves the following key steps:

Installation of a Mitigation System: A specialized radon mitigation system is
installed. The central component of this system is a PVC pipe that runs from the
ground beneath the building (below the concrete slab) up through the structure
and out through the roof or exterior wall.

Sub-Slab Depressurization: A fan, known as a radon mitigation fan or radon fan,
is installed in the PVC pipe. This fan creates a negative pressure or vacuum
beneath the building’s foundation, drawing radon gas from the soil into the
pipe. As the radon-laden air is pulled away from the soil, it is safely vented
above the roofline or to the exterior, where it dissipates harmlessly into the
atmosphere.

Sealing Entry Points: Any openings or cracks in the foundation that may be
allowing radon entry are sealed to prevent further radon infiltration.

Monitoring and Verification: After installation, the system is typically
monitored to ensure it is effectively reducing radon levels to acceptable
levels. Periodic testing may be conducted to confirm the system’s continued
efficiency.

Sub-slab depressurization is considered one of the most reliable and effective
methods for radon mitigation. It is often the preferred choice because it
actively removes radon gas at its source, preventing it from entering indoor
living spaces. This method can be customized to suit different building types
and configurations, making it adaptable to various construction designs.

--------------------------------------------------------------------------------

Sub-membrane depressurization (SMD)

Sub-membrane depressurization (SMD) is another effective technique used in radon
mitigation to reduce elevated radon levels in buildings. Similar to Sub-Slab
Depressurization (SSD), SMD is designed to prevent radon gas from entering
indoor living spaces by creating a pressure differential. However, SMD is
specifically used in crawl spaces or areas with dirt or gravel floors covered by
a plastic membrane or vapor barrier.

Here’s how Sub-Membrane Depressurization works:

Installation of a Mitigation System: A specialized radon mitigation system is
installed in the crawl space area. The central component of this system is a PVC
or similar pipe that is placed beneath the plastic membrane or vapor barrier.

Sub-Membrane Depressurization: A fan, known as a radon mitigation fan or radon
fan, is installed in the pipe beneath the membrane. This fan creates a negative
pressure or vacuum between the plastic membrane and the soil or gravel
underneath it. As a result, radon gas that might otherwise migrate through the
soil and into the crawl space is drawn into the pipe beneath the membrane.

Ventilation and Discharge: The radon-laden air collected beneath the membrane is
safely vented to the outdoors, either through the roof or an exterior wall. This
allows the radon gas to dissipate harmlessly into the atmosphere.

Monitoring and Verification: After installation, the system is typically
monitored to ensure it is effectively reducing radon levels in the crawl space
to acceptable levels. Periodic testing may be conducted to confirm the system’s
continued efficiency.

Sub-membrane depressurization is particularly suitable for crawl spaces with
dirt or gravel floors that are covered by a plastic vapor barrier or membrane.
It is designed to address radon issues in these specific areas and is considered
an effective method to prevent radon from entering the building’s living spaces.

Sump/Drain-Tile Depressurization (DTD)

Sump and drain-tile depressurization is a radon mitigation technique used to
reduce elevated levels of radon gas in buildings, particularly in basements or
crawl spaces. Radon is a colorless, odorless, and radioactive gas that can seep
into homes and buildings through the soil and foundation. Prolonged exposure to
high levels of radon can increase the risk of lung cancer.

Here’s how sump and drain-tile depressurization works:

Sump Pump: Many homes have sump pumps installed in their basements or crawl
spaces to prevent water buildup and flooding. A sump pump collects excess
groundwater and pumps it out of the building. In a sump and drain-tile
depressurization system, the sump pump pit is used as part of the mitigation
system.

Perforated Drain Tile: Perforated drain tiles are pipes with small holes or
perforations designed to collect water from the surrounding soil. These drain
tiles are typically installed around the perimeter of the basement or under the
basement floor. They help manage excess water and moisture.

PVC Pipe and Ventilation: In a sump and drain-tile depressurization system, a
PVC pipe is connected to the sump pump pit and/or the perforated drain tiles.
The pipe is routed to the exterior of the building, usually through the roof or
an exterior wall. An exhaust fan or blower is installed in the PVC pipe to
create a negative pressure or suction in the soil beneath the building.

Radon Gas Removal: As the fan or blower operates, it draws air and soil gases,
including radon, from beneath the building’s foundation. This prevents radon
from entering the living space and instead directs it safely outside, where it
quickly dilutes in the outdoor air and poses no health risk.

By creating this depressurized zone beneath the building, the sump and
drain-tile depressurization system effectively reduces the entry of radon gas
into the indoor environment. It’s an effective and commonly used radon
mitigation method, especially in areas where elevated radon levels are prevalent
in the soil.

Heat Recovery Ventilators (HRV)

We have installed many direct ventilation systems where the standard mitigation
system listed above is unavailable. Sometimes it is more cost-effective to
install an HRV where other mitigation methods can get expensive.

A Heat Recovery Ventilator (HRV) is a mechanical ventilation system designed to
improve indoor air quality in buildings while also conserving energy. HRVs are
commonly used in residential and commercial buildings to provide controlled
ventilation by exchanging stale indoor air with fresh outdoor air. They are
particularly useful in buildings with good insulation and airtight construction
to ensure proper ventilation without excessive heat or energy loss.

Here’s how an HRV works:

Supply and Exhaust Airflow: HRVs consist of two separate air duct systems—one
for supplying fresh outdoor air into the building and another for exhausting
stale indoor air from the building. These airflows run parallel but do not mix.

Heat Exchange Core: At the heart of the HRV is a heat exchange core, typically
made of materials with high thermal conductivity, such as aluminum or plastic.
This core allows heat to transfer between the incoming and outgoing air streams
without them mixing. In cold weather, heat from the indoor air is transferred to
the incoming cold outdoor air, pre-warming it. In hot weather, the process is
reversed, where heat from the incoming outdoor air is transferred to the
outgoing indoor air, helping to cool it.

Fans and Filters: HRVs are equipped with fans that ensure a controlled and
balanced airflow between the two air streams. Filters are also commonly used to
capture dust, pollen, and other airborne particles from both incoming and
outgoing air, improving indoor air quality.

Controls: HRVs are typically equipped with controls that allow users to adjust
the ventilation rate and other settings to meet the specific needs of the
building and its occupants. Some HRVs come with smart features that can
automatically adjust ventilation based on factors like humidity or occupancy.

Benefits of HRVs:

Improved Indoor Air Quality: HRVs ensure a steady supply of fresh outdoor air,
reducing the buildup of indoor pollutants, humidity, and odors.

Energy Efficiency: By recovering heat from exhaust air, HRVs help to conserve
energy and reduce heating and cooling costs.

Comfort: HRVs maintain a more consistent indoor temperature and humidity level
while providing fresh air, contributing to occupant comfort.

Moisture Control: HRVs help control indoor humidity levels, which can prevent
issues like mold growth.

HRVs are an effective solution for providing controlled ventilation and
maintaining indoor air quality while minimizing energy loss, making them a
valuable component of modern energy-efficient building designs.
