Sealant jobs we do in Hythe, Hampshire

Hythe looks across Southampton Water towards the city’s docks, with the New Forest at its back. Together with Dibden Purlieu it makes up the parish of Hythe and Dibden, a town of around 20,500 people in the New Forest district. Mr Mastic covers Hythe from our base in Crawley, resealing bathrooms and kitchens and replacing mastic on windows and doors that take the brunt of the weather off the water.

Whatever the job, the method does not change. We remove the old sealant completely, treat mould, clean and dry the joint and lay a new bead chosen for the surface and the exposure. Outside, that usually means a durable weatherproof sealant with backing rod; inside, an anti-fungal sanitary silicone.

A village that grew into a town

Hythe was a village with a ferry and a pier for centuries, and its old High Street area still has older buildings, such as the red-brick church of St John the Baptist from 1874. The real growth came after the Fawley refinery expanded. A 1953 plan proposed turning Hythe and Dibden Purlieu into a small town of 10,000, and the two have since merged into one built-up area, with Dibden Purlieu alone now home to around 4,000 people.

That makes much of Hythe’s housing post-war: family estates, semis, bungalows and flats from the 1950s onwards. Many have had several bathroom refits, and the sealant left behind is often layered, hardened or mouldy. Building work on Hythe Marina began in 1985, and the large houses around it overlook the water, with big glazed areas and balconies where external joints do a lot of work.

Whether it is a 1960s bathroom or a waterfront patio door, the answer is a full cut-out and reseal. Our glazing sealant page covers larger windows and glazed doors.

Salt spray and wind across Southampton Water

Homes along the shore and around the marina face open water, and wind-driven rain and salt are hard on external mastic. Joints on south- and east-facing frames dry out, harden and split, and once they open, rain gets behind the frame and into the wall. We check sills, thresholds and the joints under them, not just the frame edges, and use flexible sealant that can move with the building.

Flats and apartments near the waterfront bring their own planning: access, parking and, often, a managing agent. A failed shower seal in a flat tends to show first on the ceiling below, so we are happy to talk to the agent about keys and access before the visit. Older blocks from the town’s post-war growth often have compact bathrooms where baths sit tight between walls, so we take care to cut out old sealant without scratching tiles or acrylic, and we leave the room clean.

Marina businesses, the High Street and landlords

Hythe’s High Street, with its library and shops, has Waitrose and Lidl, independent shops and charity shops, and Hythe Marine Park, on the site of the former RAF Hythe, is now a business park for marine firms. The Hardley Industrial Estate is close by. Staff washrooms, kitchens and showers in workplaces like these need resealing from time to time, and out-of-hours working can be arranged.

We also reseal for landlords and letting agents between tenancies, and our sealant guide for landlords explains what to check at each change of tenant.

Questions from Hythe, Hampshire

Do you cover all of Hythe?

Yes. We cover Hythe and Dibden Purlieu, the marina, and nearby Dibden, Holbury and Fawley.

My marina house has big glazed doors. Can you reseal them?

Yes, where they can be reached safely. We cut out the old sealant and use a durable weatherproof product suited to glazing.

Why does the mastic on my sea-facing windows fail so fast?

Wind, salt and sun dry out external sealant faster than inland. A flexible sealant at the right depth, with backing rod, lasts longer.

Can you work in a flat with a managing agent?

Yes. We can arrange access and parking with the agent before we come.

My 1960s house in Dibden Purlieu has several layers of old sealant. Can you get it all off?

Yes. We cut and scrape out every layer and clean the joint fully before resealing, so the new bead bonds properly.

Do you work on business units at Hythe Marine Park?

We take on commercial sealant work, and out-of-hours working can be arranged so staff are not disturbed.

Can you reseal over my old sealant?

No. New silicone will not bond to old, so we always remove the old bead completely.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee.
