I'm looking for a skilled tradesperson to help with an insulation job on a semi-detached home. The project involves inspecting attic and cellar access, adding mineral wool insulation where gaps exist, sealing drafts around doors and windows, and ensuring ventilation is balanced. I prefer environmentally friendly materials and tidy workmanship. Please provide an estimate for materials and labor, and note any structural considerations or permits if required. I’m flexible on dates but would like to complete the work within a couple of days. Access is through the kitchen and utility room; a brief safety briefing and cleanup at the end would be appreciated.
