Need someone to assess and seal gaps for home insulation

I'm looking for a reliable handyman in Ireland to help with an insulation-related task. The project involves inspecting exposed gaps around windows and doors, sealing air leaks, and recommending additional insulation improvements if needed. I don’t need major rewiring or demolition—just a practical, tidy job to reduce drafts. Please provide an estimate for materials (if any) and labor, along with any safety credentials or insulation product knowledge you have. Flexible on timing, but I’d like to complete this before winter and prefer a tidy, communicative worker who respects apartments as well as houses.
