County Construction Chemicals Ltd. / Sealants Online

From humble beginnings, starting out as a mastic contractor in 1971, working in and around London in a specialist trade and then progressing into distribution 10 years later, it’s fair to say, now nearly 50 years on, as a company, we’ve evolved and carved a firm slot in the mastic joint sealant and waterproofing material distributor market. Specialising in all types of mastic joint sealants, with a large stock holding, we’re proud to say that we officially have the largest range of silicone colours in the whole of the UK, FACT! As well as friendly and popular showroom counter in Chingford, North-East London, we’ve also grown our online, E-Shop business www.sealantsonline.co.uk to become one of the UK’s largest online suppliers of high quality building and waterproofing materials.
