Mastic man in Watford

Sealant jobs we do in Watford

Watford is a busy, built-up town where Victorian terraces, interwar suburbs and new blocks of flats sit within a few minutes of each other. Mr Mastic covers the whole borough from our base in Crawley, resealing showers, baths, basins and kitchens and replacing hardened mastic around windows and doors.

The most common call we get is about a shower that has started to leak or look grubby along the tray. Usually the sealant has lost its grip, or mould has grown into it, and the only lasting fix is to remove it completely and start again. Our shower resealing page describes how we do it, from cutting out the old bead to letting the new one cure.

Railway terraces, Mock Tudor streets and new flats

The town began to grow after the railway opened in 1838. New streets such as Queens Road and Clarendon Road were laid out in the 1850s and 1860s, and in the 1890s smaller houses went up west of the old town and east of the railway in Callowland, now North Watford, where red-brick terraces still line the streets. Oxhey grew around the same time to house railway workers. In the 1920s the council built the Harebreaks estate, and in the early 1930s the land of the old Cassiobury estate was laid out with the Mock Tudor houses that give that area its look. Today, new neighbourhoods are taking shape too, including Watford Riverwell in west Watford, planned for close to 1,000 homes.

In the terraces, bathrooms are often in rear extensions or carved out of a small bedroom, and timber floors flex when the bath is filled, so the sealant needs to be flexible and properly bonded. The 1930s houses have usually had their bathrooms refitted several times, and we often remove more than one layer of old silicone. In new flats, we see builder’s sealant that has cracked as the building settles.

Kitchens follow the same pattern. Worktop joints and the seal behind the sink take daily splashes and knocks, and once they shrink or blacken, moisture can creep into the worktop edge. We cut them out and reseal with a hygienic, food-safe silicone near the sink.

What we do in Watford

• Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
• Window & door mastic: Cracked or shrunken mastic around window and door frames, sills and patio doors replaced with a weatherproof sealant.
• Commercial & hotel sealant: Guest bathrooms, staff washrooms and kitchens in commercial buildings resealed in a planned order that keeps the site running.
• Remedial sealant & repairs: Second opinions on sealant that keeps failing: we strip it out, check for movement or leaks and reseal it properly.
• Fire-rated sealant: Fire-rated sealant for service penetrations and frame gaps where it has been specified, applied to the tested details.
• External & façade joints: Outside movement joints given new backing rod and a flexible, weatherproof sealant in a colour to match the wall.
• New-build mastic & snagging: Snagging sealant for new homes and plot-by-plot mastic for builders and developers.
• Floor & skirting joints: Floor and skirting joints in homes, shops and warehouses sealed neatly and to the right depth.
• Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.

• Gutter, fascia & soffit sealing: Gutter unions, outlets and fascia joints that leak in heavy rain cleaned and resealed.
• Sand mastic for sash & case windows: Traditional burnt sand mastic renewed around sash and case windows and doors in stone and brick.
