Why Remove Cavity Wall Insulation?
Debris that has fallen into the air-space (cavity) can create a platform for moisture to travel across and penetrate the vertical layer resulting in damp and sometimes the formation of fungi and mould growth visible on the inner side of the exterior walls. Debris/obstructions can also build up at the bottom of the Cavity and allow moisture to transmit upwards through the obstructions also resulting in damp.
It’s absolutely essential that the cavity must be free of significant blockages such as debris and rubble. Since the inception of cavity wall construction, properties have been identified as having minor and sometimes major blockages/obstructions within the cavity.
The causes for these obstructions can include:
When the property was constructed, the cavity was not cleared correctly prior to completion
Alterations to the propertyi.e. extensions, walls removed, wall tie replacements etc.
Cavity exposure – normally through window / door replacement or conservatory installation
General improvements / repairs – fitting of balanced flue boiler systems / vents being installed
Replacement of wall ties allowing inward motion of debris / rubble into the cavity
Other reasons to remove cavity wall insulation are if the property has been flooded or has had fire, escape of water, subsidence or impact damage.
Ecosave will fully inspect the insulation to report on what damage has occurred. Should the removal of insulation be recommended, we extract the material and re-install using EPS Bead, complying to current Building Regulations and comes with a CIGA backed 25-year guarantee
All our staff are fully trained and experienced in Cavity Wall Extraction and insulation and hold all the necessary certifications.
