Sealant jobs we do in South Benfleet
South Benfleet looks out over Benfleet Creek towards Canvey Island, with the old village tucked at the foot of the Benfleet Downs and twentieth-century suburbs spreading up the hill behind. It shares a post town with Thundersley and Hadleigh and is part of Castle Point. Mr Mastic covers South Benfleet from our base in Crawley, resealing bathrooms, kitchens, windows and outside joints.
Most calls here start with a shower. A tray that has dropped slightly, a screen with a gap at the bottom, or a seal that has shrunk away from the tiles will let water into the floor long before anything shows. Our guide to leaking shower sealant lists the signs, and when we visit we remove every trace of old silicone before resealing.
Weatherboarded village, plotland bungalows and suburban streets
The old village around St Mary’s Church is a conservation area, and Castle Point Council has had an Article 4 Direction in place there since 1997, which brings changes to windows, roofs and painting under planning control. The council’s appraisal describes the older buildings as timber-framed, finished in render or timber weatherboarding with tiled roofs, and originally fitted with timber sash and casement windows, most of which have since been replaced.
Up the hill, much of the town was built on former farmland sold off in small plots. Kents Hill Road, for example, was a farm track that became the Kents Hill Estate in the 1920s, with bungalows on large plots, some of them built with little in the way of foundations. Many of those bungalows were later extended or replaced with houses. That history leaves a lot of homes with extensions of different ages, where old and new walls meet and bathroom floors can move slightly.
The suburbs to the north and north-east filled in through the middle of the twentieth century with semis, bungalows and small blocks of flats, most now on their second or third bathroom.

Extensions, bungalows and wet rooms
Bungalows are common in South Benfleet, and many owners are adapting them for later life with walk-in showers or level-access wet rooms. A wet room only works if every joint is sound: floor to wall, around the drain, and at the base of the screen. Our wet room sealing covers those joints with sealants suited to standing water.
In extended houses, a crack often appears where the new wall meets the old, inside and out. Outside, we cut out failed mastic around frames and at movement joints and use a flexible exterior sealant. In the conservation area, we check with you about colour and finish before we start.
Village restaurants, station-side businesses and lettings
The conservation area holds a cluster of restaurants and pubs in old timber-framed buildings, where kitchens and customer toilets work hard. Benfleet station, on the c2c line to London Fenchurch Street, also makes the town popular with commuters and their landlords.
We reseal kitchens and washrooms outside service hours where possible, and for landlords we work between tenancies and send photos for the file. A loose toilet seal is a common inventory note in rentals, and our toilet base resealing deals with it neatly.

Nearby towns we cover
South Benfleet: common questions
Do you cover all of South Benfleet?
Yes. We cover the old village, Kents Hill and the streets towards Thundersley and Tarpots, as well as Hadleigh and Canvey Island nearby.
My house is in the conservation area. Do I need permission to reseal my windows?
Resealing like for like is upkeep, but the Article 4 Direction covers window changes, so check with Castle Point Council before replacing anything.
We’re turning our bungalow bathroom into a wet room. Can you seal it?
Yes. We seal the floor-to-wall joints, drain surround and screen base with products suited to wet areas.
There’s a crack where our extension meets the house. Can mastic fix it?
If it is a movement joint, yes. We cut out the old filler and use a flexible sealant that can move with the two walls.
Can you reseal a restaurant kitchen without closing it?
We can usually work before or after service, and we use food-safe and anti-bacterial sealants where needed.
How soon can I use the shower after resealing?
Usually after around 24 hours. We’ll tell you the cure time for the product we used.
Will you remove all the old silicone?
Always. New sealant does not bond to old, so we strip the joint back fully first.
Is it worth resealing a shower tray that moves slightly?
Only once the movement is fixed. If the tray rocks, a new bead will split again, so we check the tray first and tell you if it needs bedding down.
