Our underfloor insulation process

Home eligibility survey

Before providing floor insulation, we survey your home to make sure it is eligible. We may need to lift a floorboard or make a small access hatch to examine your void’s height, moisture level, layout, piping, and the condition of your floorboards. We also measure the surface area to give you an accurate quote.

Quick and hassle-free installation


Step 1: Scan

The robot goes into the void through a removed air brick in the external wall, or through a 44*30cm access hatch created in your floor. As the robot travels through the void, a detailed 3D map is built of the underfloor space. This final check helps assess all installation details and outstanding risk.

Step 2: Spray

The robot sprays layers of insulation to the underside of the floorboards, with a typical thickness of 12cm. The insulation expands to fill all the gaps. This keeps your floor warm, dry and draught-free. The void under your floor stays ventilated, allowing the ground to breathe and avoiding the risk of damp or mould.

Step 3: Quality check

While the robot does its work, the installation is monitored to measure the thickness of the insulation applied under your floor. This allows Q-Bot to verify that the work has been completed successfully.
