Cavity Wall Extraction

If your home is suffering from damp or cold spots, it may be due to failing insulation. Cavity wall extraction is the process of removing degraded, damp, or incorrectly installed insulation from between a building’s inner and outer walls.

Retaining warmth in your home starts with professional insulation. Without it, a significant amount of heat escapes through the roof. Our team helps you lock in that heat, lowering your energy bills and improving comfort throughout the year. Every property is unique, which is why we avoid “one size fits all” approaches. Whether you require loft upgrades or cavity wall extraction, we tailor our services to deliver the best results for your home.

How do we remove Cavity Wall Insulation?

Our process is a precise engineering task designed to clear out failing material without affecting your home’s structural integrity. We begin with a borescope survey to identify damp or slumped areas. Specialists then perform strategic drilling into mortar joints, creating specific entry points for our equipment.

The extraction uses high pressure air to loosen debris while industrial vacuums pull the material into a sealed unit. Once a final inspection confirms the cavity is clear, we restore the brickwork with matching mortar and provide a certificate of completion along with a 2 year warranty.

Our Process

Comprehensive Site Survey

Before any work begins, we conduct a detailed assessment using borescope cameras. This allows us to inspect the condition of the existing insulation inside the walls and identify specific problem areas, such as damp or debris, to plan the extraction effectively.

Strategic Drilling

To access the cavity, our specialists drill small, unobtrusive holes in the mortar joints of your external brickwork. These holes are positioned according to a specific pattern to ensure that the extraction equipment can reach every part of the wall without affecting the structural integrity of your home.

High-Pressure Extraction

Using specialised industrial vacuums and compressed air tools, we begin the removal process. High-pressure air is blown into the cavity to agitate and loosen the degraded or damp insulation, which is then powerfully vacuumed out through the extraction points into a sealed unit.

Cavity Clearance and Inspection

Once the material is removed, we use borescope cameras again to verify that the cavity is completely empty and clean. This step is vital to ensure no “cold bridges” or damp pockets remain, restoring the essential air gap between your inner and outer walls.

Site Clean & Warranty

Once the extraction is verified, we fill the drill holes with matching mortar to ensure a seamless finish that blends with your brickwork. We clear all debris from the site, leaving your property tidy and your walls ready to breathe again. Upon completion, we issue a formal certificate and a comprehensive 2-year workmanship warranty. This guarantees that all work meets the highest professional standards, giving you complete confidence and long-lasting peace of mind.
