Installation time varies by project. Attic insulation typically takes 1-2 days, cavity wall insulation can be completed in a single day, while dry lining may take 3-5 days depending on the area covered.

For attic insulation, we ask that the attic is accessible and any stored items are moved. For cavity wall, we need access to external walls. We'll provide a detailed checklist before installation day.

When installed correctly by certified professionals, insulation does not cause damp. Our surveyors assess ventilation and moisture levels before work begins, ensuring proper installation that protects your home.
