If a radon test has revealed there are high levels of radon within your property, it is likely that your next step will be to investigate remedial measures that can be installed to reduce the radon level. There are two main remediation techniques available for lowering your radon levels: installing a radon sump or introducing positive pressure.
Our fully qualified team have many years of experience implementing these methods in buildings and successfully bringing radon levels down to an acceptable concentration. To get in touch with our team simply fill in the form below or call 0800 012 6451.

Different Types of Radon Remediation
A radon sump is a popular and effective choice when it comes to radon level reduction and is the ideal choice for situations where there are high radon concentrations. A void is created beneath the building which effectively becomes the lowest point of pressure.
This means that any gas in the soil will be drawn to it. Once the gas has reached the void it can be safely vented away from the property via an exhaust pipe incorporating a fan. The exhaust pipe will discharge any harmful gases a safe distance from the property well away from doors and windows, usually above eaves level.
New buildings in radon affected areas often have a radon sump incorporated under the floor at the time of construction, ready to be brought into use if testing shows it is necessary.
A perforated sump box is usually installed centrally beneath the building with pipework capped-off beside an external wall. To activate the sump, a fan should be fitted to the pipework and the exhaust pipe extended.
Positive Pressure Systems
The second method of radon reduction, positive pressure, involves the installation of a special fan in an attic or loft or on the internal side of an external wall if a roof void is not present. The fan draws clean air into the property and disperses it around the property to very gently pressurise the building. In doing so, this will inhibit radon from the soil from being ‘sucked’ inside, meaning radon levels can be safely reduced.
Radon Mitigation Installation Cost
Once the most appropriate method has been chosen, there are numerous factors that will affect the cost of installing the radon mitigation system. These include, but are not limited to:
Size of the property: If a property has a large footprint, or for example is long & narrow rather than ‘square’ a single system may not be adequate to reach all areas, so two or more installations may be required. Properties on more than two levels, particularly those with basements, also often have additional requirements.
Layout & history of the property: Properties that have been extended may be more complex to remediate due to differing floor constructions and ‘compartmentalisation’ of subfloor areas by foundations.
Construction materials: Not all properties are constructed with standard red bricks; we are often required to drill through solid stone walls or even, in the case of commercial buildings, reinforced concrete walls that have been specifically designed to be very difficult to penetrate.
Aesthetic considerations: It may be desirable for the pipework from a sump to be installed in a particular location to minimise its visual impact
Electrical connections: Both positive pressure systems and radon sump fans require an electrical connections, which can usually be provided from a nearby existing circuit. External weatherproof cabling is required for fans located outside.
Equipment required: Fans with different air movement capacities and functionalities are specified depending upon the radon level, ground material and internal conditions.
