Your local mastic man for Billericay
Billericay is a commuter town with a historic High Street at its heart and well-kept family homes around it. Many of those homes have good quality bathrooms and kitchens where the sealant is the first thing to look tired. Mr Mastic covers Billericay from our base in Crawley, and we reseal baths, showers, basins and worktops, and renew the mastic around windows and doors.
Where the finish matters, we take extra time. Old sealant is cut out cleanly without scratching tiles or worktops, and the new bead can be matched to grout, stone or a coloured suite. Our colour-matched resealing page shows the range we can work with, so the joint blends in rather than standing out as a white line.
Georgian frontages, a railway suburb and converted hospital buildings
Billericay began as a market town in the old parish of Great Burstead, and the High Street still has Georgian houses and listed buildings along it. The Billericay High Street conservation area protects that core, and Great Burstead and Little Burstead each have conservation areas of their own. On older buildings like these, joints around timber windows and doors need a sealant that moves with the frame, and the colour has to sit comfortably with paintwork and brick.
The railway arrived in 1889, and the town grew from under 2,000 people in the 1840s to more than 28,000 today. Most of that growth is 20th-century housing in districts such as Queen’s Park, Sunnymede, South Green, Great Burstead and Noak Hill: detached and semi-detached houses and bungalows, many extended, with refitted bathrooms, en suites and replacement double glazing. Our usual work there is renewing bath and shower seals, kitchen worktop joints and window mastic that has hardened in the sun.
On Norsey Road, the former St Andrew’s Hospital site was redeveloped as housing, and the listed workhouse buildings were converted into homes. Conversions like that combine old walls with modern bathrooms, which makes careful sealing important.

Period buildings, extensions and quiet roads
In and around the conservation areas, the main thing is to respect the building. On a listed or period frame we cut out failed mastic by hand rather than with heavy tools, and we pick a sealant colour that suits the joinery. Our window mastic guide explains what we look for before replacing it.
Elsewhere in Billericay, extensions are common, and the joints where a new wall meets an old one, or where a roof light or bi-fold door sits in new brickwork, often crack as the extension settles. Flats above High Street shops and the newer apartment blocks near the station bring the usual issue of leaks into the flat below, so we act quickly when a shower seal has failed.
High Street businesses, schools and lettings
The High Street mixes shops, cafés, restaurants and offices, many in older buildings with small staff kitchens and washrooms that need resealing every few years. We can work early or late so that businesses can stay open. Schools, including Mayflower High School and Billericay School, have toilets, changing rooms and kitchens that are best resealed in the holidays.
Billericay’s commuter appeal also brings a steady rental market. Landlords and letting agents use us between tenancies to strip out mouldy sealant and reseal kitchens and bathrooms, so a property looks clean and well kept when the next tenant moves in.

Billericay: common questions
Do you cover all of Billericay?
Yes. We cover the whole town, including Queen’s Park, Sunnymede, South Green, Great Burstead and Noak Hill, plus nearby Little Burstead, Stock, Ramsden Heath and Ramsden Bellhouse.
Can you reseal windows on a period building in the conservation area?
Yes. We remove old mastic carefully by hand and choose a sealant colour that suits the frame and brickwork.
Can you match the sealant to my grey grout?
Yes. We carry a range of colours and can match sealant to grout, stone worktops and coloured sanitaryware.
The joint where my extension meets the house has cracked. Can you seal it?
Usually, yes. We cut out the old joint, add backing rod if it is deep, and use a flexible external sealant that can take some movement.
Do you reseal en suites as well as main bathrooms?
Yes. Many Billericay houses have one or more en suites, and we can reseal them all in one visit.
Can you work in a school during the holidays?
Yes. We are happy to plan school washroom and kitchen resealing around term dates.
Will you reseal over my old silicone to save time?
No. New silicone won’t bond properly to old, so we always take the old bead out completely first.
Can you reseal a flat in the converted St Andrew’s Hospital buildings?
Yes. We reseal bathrooms and kitchens in converted and listed buildings, taking care with older walls and arranging access through the managing agent if needed.
