DSIDE tracks 78 silicone sealants priced between £1.20 and £90.91 from 10 brands. Prices are compared across UK retailers and refreshed continually; only quotes updated within the last 72 hours are shown, so the figures above reflect what these products cost right now rather than a historical average.
The widest choice here comes from Everbuild (16), NoNonsense (14), Soudal (13), Dowsil (9), Mapei (9) and Bostik (8). Use the filters to narrow by brand or price, or sort by price to see the cheapest silicone sealants first.
