About PJ Mastics LTD

Welcome to PJ Mastics LTD. We are a premier, family-run sealant application specialist based in Norfolk, delivering flawless, professional joint sealing across residential, commercial, and industrial sectors.

With a combined 53+ years of hands-on industry experience, we have built a reputation for reliability, precision, and unrivalled trade knowledge.

Our History & Heritage

PJ Mastics LTD was officially established in 2010 by Peter, but our roots go back much further. Peter began mastering the trade in the early 1980s, later launching PJ Sealants in the 1990s. Today, the business is proudly run as a father-and-son team. Having grown up in the trade, we live and breathe sealant application.

We aren’t a massive agency that sends temporary sub-contractors to your site. We are a family business, which means our personal reputation is on the line with every single joint we seal. To us, perfection isn’t just a target—it’s personal.

        Peter and Connor have just completed 'masticing' the externals and internals of our new retirement home and their workmanship is seriously outstanding. We are absolutely delighted with the finish and would be happy to recommend them.

        I needed some mastic doing in my bathroom and kitchen quite urgently as I had been let down by another company. Connor and Pete were able to come out the next day and get it done for me. Neatly finished, cleaned up after themselves and complimented my brew! I would definitely use them again!

        Prompt efficient helpful. Cured the leaks where others failed! A neat job and no mess. Peter pointed out why previous seals failed, cleaned out old mastic and made a lovely job with a new proper mastic seal.
