About 3C Sealants

History

Starting out as a mastic contractor in 1971 known nationwide as County Mastics and progressing into distribution 10 years later with a sister company which is County Construction Chemicals Ltd. then branching out to internet sales with our e-shop Sealants Online, we have over 45 years mastic sealant experience.

In this day and age, it's not something that happens by luck or by chance and as a friendly, family-run business, this is a landmark we're very proud of!

We're now one of the UK's largest independant suppliers of high quality building and waterproofing materials, specialising in mastic joint sealants.

As a preferred supplier and specialist distributor, County Construction Chemicals Ltd. have a long-standing reputation for providing only the highest quality, proven materials from the most trusted names in the business like Dow Corning, Geocel, Sika Everbuild, Tremco illbruck, Nullifire, Fosroc, Otto Chemie, Mapei, SafeGuard Chemicals, Resiblock, DL Chemicals, PC Cox (now Cox Sulzer Mixpac UK), C-Tec CT1, Adshead Ratcliffe Arbo, Repaircare International and more.

We have not, and will not compromise on this high standard and strive to advance with the ever-changing market, to bring you the very best materials in a helpful and professional manner.

With our great reputation, experience and vast knowledge of the mastic joint sealant industry, we thought it was about time we had our own brand, hence the introduction of...

Service

Why are we successful and why do customers give us repeat business?

We believe that trust is built and earnt with our customers! Our ethos, from day one, has been to evolve our business at just the right pace instead of being gung-ho in the marketplace, squashing margins and roping in custom with loss-leaders, so as to keep up a high level of quality and service, with attention to detail being paramount to our operation.

There's always been competition in the specialist builders merchant market, so we've always strived to go the extra mile when it comes to our customers, to set us apart with fantastic customer service and useful, informative advice and recommendations.

We've been sending out mastic sealant orders from 1 x single tube to many pallet loads, for decades before the internet revolution and thus we're well versed in the speedy and safe delivery of mastic sealants, using only the best multi-national networked, courier services and where appropriate, local, rapid-response delivery services.

For any aftersales delivery enquiries, amendments or errors, we have a dedicated customer service team.

We also realise that over-ordering, changing circumstances and other factors can affect already placed/received orders and so, accept returns as per our general returns policy and will try our utmost to assist our customers with any AFTERCARE they may require.
