About Darren Salton Mastic Man
Professional Mastic & Sealant Services - and Hands on Training in Bedfordshire
I'm Darren Salton. Mastic and sealant specialist. Based in Bedford.
Six years doing this properly.
I'm not the cheapest mastic man in Bedfordshire. I'm the one people call when they want it done properly - first time.
Every job gets the same standard - proper prep, clean lines, no rushing, no cutting corners. Whether it's one bathroom or a full week's work, the approach doesn't change.
My reputation has been built one job at a time across Bedfordshire, Hertfordshire and Buckinghamshire. Most people find me through Facebook or a recommendation from someone whose bathroom I've already done. Word travels when the work speaks for itself.
I'm also proud to run the Mastic Man Training School.
From my purpose-built studio in Bedford I teach the exact same techniques, tools and standards I use every day on client jobs. Two trainees at a time. Hands-on from the first morning. No PowerPoints. No YouTube clips. Just proper, practical training that gives people a skill they can earn from immediately.
One of my trainees completed his first paid job on the final afternoon of the course. £200. Same day.
That's what this training does.
If you want mastic done properly - or you want to learn how to do it properly - you're in the right place.

It's the detail at the end of many jobs that determines the quality of the finished product - and Darren has certainly lifted the appearance of my kitchen. A pleasure to have met him.
