Specialist distributor of coloured mastic joint sealants, adhesives, waterproofing products, stone, concrete and wood care & repair materials


Who are we and what do we do?

The purpose of this About CCC Ltd. page is to allow us to introduce County Construction Chemicals Limited. 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.

The CCC Ltd. Way

With a heavy focus on the fastest delivery becoming the number 1 priority for many consumers, customer service has become a secondary consideration. We’re somewhat reluctant to get carried away with the Amazon Prime type of service, opting to maintain a connection with our customers directly, providing advice and assistance, whilst still providing a solid service with detailed delivery information, something that other companies who sell the same or similar product ranges to us fall short on. Most of these ‘middle man’ companies offer no direct contact details and simply intercept business online, lacking any technical knowhow and promising fast deliveries, then sending the goods direct from the manufacturer, often undercutting everyone else online, earning unfeasible, low margins with no longevity to their business model and ultimately affecting their overall service and performance. We’ve been distributing materials from our warehouse in Chingford, North-East London for over 40 years, using trusted, national courier services and/or local delivery services where possible within London and the surrounding counties.

History & Key Events


County Mastics (Contractors)

Spotting a gap in the market for a dedicated, mastic joint sealing application company, a small family business named COUNTY MASTICS was formed close to the city, on the outskirts of North-East London, with just a single mastic gunner and bare minimum office staff. After much consistent, high quality work, word soon spread in the local London & Essex construction industry and further contracts were acquired, including such prestige projects as Buckingham Palace, 10 Downing Street, Windsor Castle and some of the early stages of the popular landmarks known today in the City and West End of London. The business went from strength to strength and additional staff were taken on for this expansion. Scroll further to see more About CCC Ltd.


About CCC Ltd.(County Construction Chemicals Limited)

After 10 years of mastic joint sealing & waterproofing, County Mastics was well established in the area with a growing workforce. As the contracts were flowing, additional materials were being procured and used progressively more. This lead to early negotiations with the major sealant manufacturers such as Fosroc Expandite, Dow Corning (now Dowsil) UK distributor Geocel, waterproofing giants Sika and Adshead Ratcliffe to keep larger stocks and further product lines, quickly evolving into a small distribution division. This new branch of the business was named County Construction Chemicals Ltd. and the racks of County’s small yard in Highams Park (North-East London) were overflowing with the latest mastic sealant products in the business, servicing the fellow, specialist mastic firms plus the various other trades who used these products in their work in and around London, Essex, Middlesex & Herts.

Deliveries/Larger Premises (Chingford)

Growth meant expansion and with that, a requirement for more storage and administrative space, so both County Mastics (contractors) and County Construction Chemicals Limited. was moved a short distance to a warehouse with offices on the edge of Chingford, within easy reach of the M25, north circular and other major motorways. More space created more potential, so a small, manned trade counter was setup to serve customers either on their way in, or way out of London and courier service was used to ship products to customers. Such was the demand for materials, the range was expanded to include specialist adhesives, waterproofing materials, concrete repair products and relevant tools & accessories.

Dedicated delivery service for CCC Ltd.

Further expansion was inevitable as the company reached it’s 20th year in business and, with the restructure of the warehouse shelves to accept further stock, also came the recruitment of locally-based haulage drivers and a transport manager to streamline the deliveries to customers both in London and farther afield in Essex, Middlesex and Herts.


Warehouse extension for CCC Ltd.

An investment in a sister company called Speed Drill, (a specialist diamond drilling contractor), was made, the adjoining unit was acquired and the warehouse structurally altered and extended to create space for separate office space and further storage for the 3 x companies. The transport manager (Tony) took over as permanent stores manager and becomes a popular and well-known face in the mastic sealant & waterproofing industry (in fact he’d still be in that role at Countys 27 years later!)


CCC Ltd. Celebrated 40 Years

A milestone of 40 years total trading is reached, this is something we’re extremely proud of in this fast-paced age of fly-by-night companies that tend to come and go, trying to make a ‘quick buck’. After a very successful growth period in the early years from the contracting side, when we moved into distribution, our focus was always, and will always be, to keep a sensible, sustainable margin with attention to advice and customer service which sets us apart from the multi-national builders merchants. This 40th year landmark would mark a new venture for County Construction Chemicals,,, as we sowed the seeds for an entry into the world of online retail.


Set Up E-Shop Sealants Online

“It’s the future!” was the frequently heard statement from staff members, manufacturers and customers alike when any conversation involved the internet, or in particular selling online! This was always the plan for CCC Limited. but instead of ‘keeping up with the Jones’ and just start selling through Ebay or setting up a small, generic, ecommerce website to intercept scraps of business, we wanted a stable, secure, informative website that had scope for continued expanison, so we we took our time, researched the marketplace thoroughly and decided the exact business model we wanted to follow and then worked hard over the course of a year, designing and developing our E-Shop, preparing to launch on the world wide web! We didn’t know quite what to expect, but it was time…….  WWW.SEALANTSONLINE.CO.UK was born!


CCC Ltd. Own Brand Materials

After many years in the mastic sealants, adhesives, waterproofing, stone care and wood repair business, we like to think we have a good eye for product solutions and decided now was the time to introduce our very own labelled materials into the market. 3C Sealants came first with a carefully selected range of just a few acrylic and silicone based sealant products initially, (now with several further products added). Next came Liquid Jacket a waterproofing specific range of just a few select coating based products. Both brands’ sales have grown at a steady rate over the past 24 months to a respectable level, with tried & tested products being added to the ranges when appropriate.


Modern Overhaul For CCC Ltd.

With continued growth expected coming into another financial year, further investment meant some big changes for CCC Ltd. A new state-of-the-art, fully integrated Warehouse Management System to increase productivity and streamline despatch, increased social media activity on various channels, including the launch of Sealants Social, (a friendly sociable user-led group on Facebook), local team sponsorship, both physical and digital advertising, new, extensive work on all company websites; the main business (www.county.construction) the online sales E-shop (www.sealantsonline.co.uk) and the own brands (www.3c-sealants.co.uk) & (www.liquid-jacket.co.uk) and also major build improvements to our premises to maintain the high level of service and efficiency our visiting customers have come to expect of us.
