Professional MASTIC Sealant Services Across the South West
Residential Sealant Services for Homes and Landlords
Cracked or mouldy silicone isn’t just unsightly. It lets water in where it can cause real damage.
We remove the old sealant completely, then apply fresh, mould-resistant silicone. We never seal over the top.
Bathroom Resealing
We replace mouldy, peeling or leaking silicone around baths and basins. The result is a clean, watertight finish that lasts.
Shower Resealing
Showers take more water than anywhere else in the home. A proper reseal stops leaks before they reach the floors and ceilings.
Kitchen Sealing
We reseal sinks, worktops and splashbacks using mould resistant hygienic silicone. It keeps water out and wipes clean easily.
Window & Door Sealing
Over time, mastic around frames cracks and shrinks. Fresh sealant keeps draughts and rain where they belong: outside.
Floor Perimeter Sealing
We seal joints between different floor finishes such as skirting, tiles, laminate, vinyl and walls. This creates a clean finish and prevents dirt, gaps and moisture build-up.
Silicone Removal
New sealant only works if the old silicone comes out completely. We remove it carefully, without scratching your surfaces.
Commercial sealant services for contractors and developers
On construction projects, sealant does a lot of quiet, important work. It protects fire lines, acoustic performance and airtightness. When it’s wrong, it usually shows at handover.
We work with housebuilders, main contractors and facilities teams across the South West. We work to your programme and keep you informed throughout.
Fire Rated Sealants
We install fire-rated sealant around service penetrations, gaps and compartment lines. Every joint follows the manufacturer’s tested details.
Expansion Joint Sealing
Movement joints in brick, block and concrete need room to flex. We use the right backing and sealant, so joints don’t tear.
Air Tightness Sealing
We seal gaps and penetrations ahead of your air pressure test. Getting it right first time save time and cost.
Acoustic Sealing
Acoustic sealant stops sound passing between rooms, flats and floors. We seal partition heads, junctions and service gaps.
Glazing & Façade Sealing
We seal curtain walling, glazing and façade joints. you get a clean, sharp finish that keeps the weather out.
Hygienic Sealing
Commercial kitchens, clean rooms and food areas need joints that are easy to keep clean. Our hygienic sealants are made for exactly that.
