The wonder of mastic sealant
Flexible
Mastic sealant is a unique and versatile product. It can be applied not only to join two surfaces together, but also to provide protective cover to certain areas. Plus, it has the advantage of staying flexible once it’s dried, making it very durable.
Waterproof
We regularly use mastic sealant to fit windows and doors in houses and other buildings, along with kitchens and bathrooms, where it frequently comes into contact with hot and cold water. The waterproofing properties, keep units watertight and prevent leaks.
Connects with multi-surfaces
Amazingly versatile, we can apply mastic sealant to a wide range of materials, including wood, glass, aluminium, steel and concrete. It’s an excellent all-rounder for a huge variety of projects, but if you’re unsure as to whether it’s suitable for your particular job, we’ll happily advise you.
Weatherproof
As well as being waterproof, the ultraviolet nature of mastic sealant makes it ideal for use outdoors, as it can withstand the damaging rays of the sun. So, it retains its strength much longer than most other alternative products.


Metal-friendly
We’ve also found mastic sealant to perform exceptionally well on metal. It doesn’t cause corrosion, and provides essential protection.
Priming for a precise finish
Before we make a start on your job, our sealant technicians first ensure the area is well-primed by thoroughly cleaning, and ensuring it’s perfectly dry. Although priming isn’t strictly necessary, we want to achieve the smoothest, most precise finish, and our surface-prepping is part and parcel of giving you a top-class, professional service.
Sealant lifespan
You can expect the mastic sealant we apply to work efficiently for around five years. This is the average lifespan, and we advise having it replaced once it’s been in situ for that length of time, so you continue to enjoy the trouble-free benefits of mastic sealant’s maximum protection. It will save you time, money, and hassle in the long run, to arrange with us for your sealant to be renewed periodically.
Our work covers the following sectors: private clients and companies, care homes, hospitals (both public and private), renowned hotels chains, schools, commercial new builds and high street supermarkets.
