Our team assesses each property to determine suitability and installs high-performance materials that retain warmth, improve comfort, and boost EPC ratings.

Whether you manage a single home or a large housing portfolio in Barking and across the UK, we deliver fast, certified installations that enhance energy efficiency while supporting sustainability goals.

What Are The Benefits Of Cavity Wall Insulation?

Cavity wall insulation helps lower heating bills, reduce carbon emissions, and improve indoor comfort year-round.

Proper insulation reduces energy demand by slowing heat loss through external walls. This leads to lower gas and electricity bills, a warmer home in winter and a cooler interior in summer, and reduced condensation or damp problems. It also supports improved EPC ratings, making your property more attractive to buyers or tenants and helping meet environmental standards.

What Types Of Insulation Materials Do You Offer?

A variety of cavity wall insulation materials are available to meet performance, property, and sustainability needs, including:

• Polystyrene beads for uniform coverage and drainage – Provide consistent fill and moisture resistance in cavity walls.
• Mineral wool for sound insulation and fire safety – Ideal for properties requiring acoustic performance and fire-rated materials.
• Urea-formaldehyde foam for solid fill applications – Common in older buildings or where cavities are irregular or narrow.
• Eco-friendly insulation for sustainable upgrades – Includes low-impact materials selected for environmental performance.
• Custom material selection based on project needs – Tailored recommendations factoring in building structure, exposure, and client goals.

How Much Does Cavity Wall Insulation Cost?

Costs for cavity wall insulation start from around £450 for a small flat and can exceed £1,500 for a large detached home.

Additional factors include whether scaffolding or specialist equipment is required and if government grants or ECO schemes can be applied.

How Do I Know If My Property Is Suitable For Cavity Wall Insulation?

To check if cavity wall insulation is needed, we assess the age, structure, and condition of your walls.

Most cavity wall insulation is installed in homes built between 1920 and 1990 that have unfilled cavity walls and are not exposed to extreme moisture. Our surveyors check for wall type, cavity width, and external render or cladding and ensure the property is in good repair.

How Long Does Cavity Wall Insulation Last?

Cavity wall insulation can last over 25 years when installed correctly with suitable materials. Most modern insulation types, such as mineral wool, polystyrene beads, and polyurethane foam, are designed for long-term performance and are often backed by guarantees.

Longevity also depends on factors like the quality of installation, property condition, and whether the home is in an exposed or damp-prone area.

What Is The Installation Process For Cavity Wall Insulation?

Installation of cavity wall installation begins with an initial property survey. We drill small holes in the external brickwork, typically around 22mm in diameter and spaced evenly across each wall.

The insulation material is then injected into the cavity under pressure to ensure full coverage. Finally, the holes are filled to match the existing finish as closely as possible, leaving a clean and tidy result.

Do You Offer Cavity Wall Insulation Removal Or Remedial Work?

We provide cavity wall insulation removal and replacement services for failed or unsuitable installations.

If insulation has caused damp, failed due to age, or wasn’t properly installed, we can extract the old material and either remediate the issue or upgrade it with new, modern insulation. We also assess for cavity wall clearance and ventilation upgrades as part of remedial works.
