Your local mastic man for Tilbury
Tilbury grew because of its docks. They opened in 1886 on the marshes beside the Thames, and the town that grew up to house the people who worked there still shapes most of what you see today: rows of older houses, post-war homes, flats and a steady flow of new building. Mr Mastic covers Tilbury from our base in Crawley, renewing bath, shower and kitchen sealant and replacing worn mastic around windows and doors.
The problems in homes like these tend to be the same few things. A shower tray seal that has turned black at the corners. A gap opening between the bath and the wall. Mastic around a uPVC window that has gone brittle and pulled away from the brick. Each of those is fixed the same way: cut out the old sealant completely, clean and dry the joint, then lay a new bead with a product chosen for the spot. If your shower is the problem, our guide to leaking shower sealant explains the signs to look out for.
From dock housing to brownfield rebuilds
The workers who dug the docks were first housed in temporary buildings or travelled in from nearby villages. Permanent housing followed, some of it poorly built, and conditions in the town did not improve much until government money became available around 1918. The Port of London Authority also drew up housing of its own, including a 1920 scheme for police and firemen designed by Sir Edwin Cooper. Much of Tilbury’s older stock dates from this period and the decades after, with bathrooms and kitchens that have been refitted several times.
Newer homes have been added on brownfield land. St Chads, built by Thurrock Council’s housing company Gloriana and designed by Bell Phillips Architects, brought 128 houses to a former redundant site in a post-war suburban part of the town and won a RIBA East Award in 2018. Between the town centre and the station, a block of 35 flats for over-55s was built on a vacant site in the flood plain. There is also recent residential building on the west side of Civic Square, and plans for more around Calcutta Road and Anchor Fields.
Each of these brings its own sealant job. Older homes need careful stripping of layers of past sealant. New ones usually need the builder’s first bead replaced once the building has settled.

Low-lying ground, flats and shared buildings
Tilbury sits on low, flat land between the river and the higher ground at Chadwell St Mary and West Tilbury. Wind across the marshes and off the Thames is hard on external mastic, especially on exposed gable ends and around ground-floor doors. We use weatherproof, flexible sealants outside and replace them in full, rather than running a new line over the top of cracked material. Our page on external joint sealing covers how we deal with deep or uneven gaps.
In flats and sheltered housing, a failed seal round a bath or shower can leak into the home below without anyone noticing at first. We can book through a managing agent or housing provider, carry everything up stairs where there is no lift, and use low-odour products where residents are at home during the work.
Port businesses, offices and rented homes
The Port of Tilbury is one of Britain’s three major container ports and handles bulk cargo, timber, cars and paper, and the London Cruise Terminal operates from the former passenger landing stage. Around the port are warehouses, depots and offices with staff showers, toilets and kitchens that need resealing from time to time. Our commercial sealant service can work out of hours so facilities stay in use during the day.
Landlords and letting agents in the town use us between tenancies, so a bathroom looks clean and sound before the next tenant arrives.

Questions from Tilbury
Do you cover all of Tilbury?
Yes. We cover the whole town, from the centre and Civic Square to Dock Road and the riverside, and nearby Chadwell St Mary, West Tilbury, East Tilbury and Grays.
My shower tray seal goes black within months. Why?
Usually mould was left behind the old bead, or the joint wasn’t dry when it was resealed. We strip it fully, treat the area and reseal with a mould-resistant silicone.
Can you deal with a leak into the flat below?
If the cause is failed sealant round a bath or shower, yes. We replace it and can point out any other issues, such as loose tiles, that need a different trade.
Do you work in sheltered or retirement flats?
Yes. We can arrange access through the scheme manager and use low-odour sealants where residents are at home.
Can you reseal staff facilities at a warehouse or depot?
Yes. We can work early, late or at weekends so showers and toilets aren’t out of use during shifts.
The mastic round my front door has shrunk away from the brick. Can you fix it?
Yes. We cut out the old material, fill deep gaps with backing rod and lay a flexible, weatherproof mastic.
