Mastic and sealant work in Locks Heath

Not much more than a century ago, Locks Heath was strawberry fields. The land was split into small plots after enclosure in 1866, and when Swanwick station opened in 1889 the fruit could be sent all over the country. Today most of those plots are houses, and Locks Heath, Warsash and Whiteley together formed one urban area of 43,359 people at the 2011 Census. Mr Mastic covers Locks Heath and its neighbours from our base in Crawley.

We reseal baths, showers, basins, toilets and kitchens, and replace failed mastic around windows and doors. Old sealant always comes out first, every bit of it; our silicone removal page explains why that step matters more than any other.

Built plot by plot, then estate by estate

Because the land was held in small plots, it was built on a few at a time. Writing in 1967, the architectural historians Pevsner and Lloyd described the suburban building here as proceeding piecemeal, and the result is a patchwork: older houses on single plots, small estates tucked in behind them, and closes squeezed between earlier roads. In the late 1980s Locks Heath and neighbouring Park Gate became a growth area for southern Hampshire, and the mid-1980s brought a large amount of new housing, along with the Lockswood Centre.

That makes a lot of local homes around 35 to 40 years old, and their bathrooms and kitchens have mostly been refitted at least once. We see acrylic baths that have dropped, shower trays where the sealant has split along the back wall, and toilets and basins with yellowed, peeling beads around the base. A neat line of sealant at the foot of a toilet or pedestal is a small job but makes a big difference; our toilet base resealing page shows how it’s done.

The 1980s and 1990s homes also have original or early replacement uPVC windows, and the mastic around them has usually hardened and cracked.

Estates, closes and the Hamble side

Most homes here are houses rather than flats, which makes access easy, but closes and cul-de-sacs can be tight for parking, so we plan visits to keep out of the way. Because so many neighbouring houses were built at the same time, their sealant tends to fail at the same time too, and it is common for a whole close to need the same jobs within a few years of each other. Where there are flats or maisonettes, a failed shower seal usually reaches the ceiling below before anyone notices, and we can arrange access through a managing agent.

Towards Warsash, at the mouth of the River Hamble, homes face more wind and weather than those inland. External mastic on exposed elevations dries out and cracks sooner, and wind-driven rain gets in behind frames. We cut out the old joints and reseal with a flexible, weatherproof product, using backing rod where the gap is deep.

The Lockswood Centre, Segensworth and landlords

The Lockswood Centre, built in the mid-1980s, holds a Waitrose, a library and community centre and the Lockswood surgery, along with the Strawberry Tavern. Nearby Segensworth has drawn businesses since the late 1980s, and Warsash Maritime Academy trains Merchant Navy officers. Washrooms, kitchens and shower rooms in places like these need resealing from time to time, and we can work out of hours.

For landlords, our guide to sealant for landlords covers when to reseal and why between tenancies is the best time.

Questions from Locks Heath

Do you cover all of Locks Heath?

Yes. We cover Locks Heath and its neighbours, including Park Gate, Sarisbury, Swanwick, Warsash, Titchfield and Whiteley.

My 1980s house still has the original bath sealant. Should I replace it?

If it’s cracked, discoloured or coming away, yes. Old sealant hardens and can’t move with the bath, so it lets water through.

Can you reseal around a toilet base and basin pedestal?

Yes. We remove the old bead, clean the floor and porcelain, and lay a neat, flexible sanitary silicone.

My house is near Warsash and the window mastic keeps cracking. Why?

Exposed walls take more wind, rain and sun, which wears out external mastic faster. We use a flexible, weatherproof sealant set to the right depth.

Do you work for businesses at Segensworth?

Yes. We reseal staff washrooms, kitchens and shower rooms, and out-of-hours working can be arranged.

How long does a bathroom reseal take?

Most baths or showers take a few hours, including removing the old sealant. We’ll tell you how long to leave it before use.

Is the work guaranteed?

Yes, every job has our one-year guarantee.

My basin sealant has gone yellow and keeps peeling. Can it be fixed?

Yes. We remove the old bead completely, clean and dry the joint, and reseal with a fresh sanitary silicone that stays white and flexible.
