Cavity Extraction & Cleaning
Evolve are specialists in the safe extraction and cleaning of cavities using specialist equipment and fully trained crews. We have tackled over 3,000 blocked or defective cavities to date.
Typically, you can expect Evolve to clear your cavities in two or three days, leaving you with clean, debris-free cavities that will no longer be at risk of allowing damp to penetrate.
If you suspect you have a problem with your cavity walls, contact us to arrange a FREE home visit during which we will use a boroscope to look inside the walls to assess the issue for you.
Understanding cavity extraction & clearance
Cavity walls are designed to be free of debris so that moisture cannot use the debris as a bridge to penetrate the internal walls of your home. However, in some cases, cavity walls are full of debris, rubble or other blockages which allows moisture into the interior of homes, causing damp problems.
It’s vital to a property’s condition that cavities are clear; damp can cause significant long term issues and blocked cavity walls are a key reason damp occurs. Of course, the exception to clear cavities is if the cavities are filled with a suitable, professionally installed cavity wall insulation.
Reasons why cavities become blocked
Our team can successfully clear all cavities, from top to bottom, of debris, using specialist equipment to blow compressed air into the cavity, forcing any present materials out into an industrial vacuum which collects the waste.
We can then either leave you with clean, clear cavities or fill them with our state-of-art bonded-bead cavity wall insulation. Either way, your cavities must not have debris in them.
