One of my bedrooms has just been measure for carpet. When the measurer was here, he saw that there was a gap all the way round underneath the skirting board. He advised me to sort it beofre the carpets went down to prevent dust, dirt, cold and even moisture getting through. This did make sense to me. However, I thought he meant silicone beading or something similar, but he said when asked, the trims like you use round laminate flooring. So: Do I actually need beading? Should it be the wooden strips or silicone? Should it be done before the carpet is fitted? I will have a go whatever is recommended cos I want the room to right. Thank you in advance for your knowledge and advice! Sue
