What Is Cavity Wall Insulation?
Cavity wall insulation is designed for properties built with a hollow cavity between the inner and outer walls. The insulation material is injected into this gap to prevent heat from escaping your building.
Key Benefits of Cavity Wall Insulation
Signs Your Home Needs Cavity Wall Insulation
You may need new or upgraded insulation if you notice:
- Cold rooms even when heating is on
- High energy bills
- Cold spots on interior walls
- Condensation or mould patches
- Difficulty maintaining consistent warmth
How Our Cavity Wall Insulation Works
We follow a professional and highly controlled installation process:
Step-by-Step Installation
Property Survey & Thermal Assessment
Our specialists inspect wall structure, cavity depth, ventilation, and existing insulation if present.
Drilling Micro-Holes
Small, unnoticeable holes are created along the wall.
Injecting Insulation Material
Using specialist equipment, insulation is blown into the cavity evenly.
Sealing & Cleaning
The holes are sealed with colour-matched mortar for a clean look.
Quality & Safety Inspection
Final checks ensure your insulation meets UK safety and performance standards.
What Is Floor Insulation?
Floor insulation prevents heat loss through suspended floors, ground floors, or concrete slabs. It creates a thermal barrier that keeps warm air inside and cold air out.

Most cavity wall insulation jobs take 2–3 hours. Floor insulation may take 1 day depending on access.
3.Will insulation reduce damp or condensation?
Yes, properly installed insulation helps reduce cold spots that cause condensation. However, if your property has structural damp, it must be treated first.
4.Does floor insulation help with noise?

High-quality insulation typically lasts over 30–50 years with no maintenance.
