01
Survey And Quote
We visit, inspect the cavity with a boroscope inspection camera, and take moisture meter readings at several points around the property. You get a fixed quote the same day, usually within two hours of the visit. If the foam is only in one elevation, we tell you that and price accordingly.
02
Set Up And Protect
On the day, we sheet floors and furniture, tape doorways, and run an air scrubber and negative air machine to keep dust inside the work zone. PPE disposable coveralls and respirator filters go on before any cutting starts. Setup takes about 45 minutes on a typical three-bed semi.
03
Cut And Extract
We open the cavity at 1-metre intervals, break the foam down with an oscillating multi-tool and reciprocating saw, and pull it out with an industrial vacuum extraction unit. A standard semi takes one to two days. Larger detached homes in Wembdon or Chilton Trinity can run to three.
04
Inspect And Dry
Every section is checked with a thermal imaging camera and moisture meter before we close it. If we find damp in the inner leaf or roof timber, we flag it and dry it out with directed airflow. This is the step that stops the problem coming back six months later.
05
Make Good And Hand Over
We repoint or plug the access holes, match the brick where we can, and leave the cavity clean and ventilated. You get a written summary of the work, photos of the cavity before and after, and a clear line on what to do next if you are reinstating insulation.
