Sealant jobs we do in Borough Green
Borough Green is a village of around 4,500 people in Tonbridge and Malling, sitting on the A25 between Sevenoaks and Maidstone, with Wrotham just across the M26 and Platt and Ightham as neighbours. Mr Mastic covers the village from our base in Crawley, resealing baths, showers, basins and worktops, and replacing tired mastic around windows, doors and conservatories.
Most of the calls we get from villages like this are about the same few things: black mould along the back of a bath, a shower tray seal that has come away, or window mastic that has cracked and gone grey. In each case the fix is the same. We remove the old sealant entirely, clean and dry the joint, and lay a new bead suited to the job. Our guide to choosing a mastic man lists the questions worth asking any firm before you book.
A railway village that grew around its crossroads
Borough Green was once part of Wrotham parish and became its own parish in 1934. Its early centre was the crossroads on the old Gravesend to Hastings route, where several coaching inns stood. The village really grew after the railway station opened in 1874: Western Road was planned in 1877, and housing spread out from the station and the A25 over the following decades. Later 20th-century homes filled in around them, and a small housing area was built on the old Basted mill site.
More recently, several former inn sites have been redeveloped as housing, including Red Lion Square, Foxlea and Tavern Close. So the village has a real spread of ages: Victorian and Edwardian houses near the station, mid-century semis and bungalows, and newer homes on infill plots.
Older houses often have bathrooms fitted into small rooms with walls that are not quite square, so the gap round a bath varies along its length. Mid-century houses tend to have second or third bathroom refits with sealant that has shrunk. Newer homes bring settling cracks in the first year or two, which our page on new build mastic explains.

Sandy ground, a motorway and commuter homes
The land around Borough Green has long been dug for sand and Kentish ragstone; a quarry beside the station supplied both until the late 1960s, when the old goods yard became a car park. The M26 runs through the middle of the parish, and homes close to it and to the A25 collect traffic grime on their window frames. Dirt sticks to old, tacky mastic, and once it has blackened and split it needs cutting out, not cleaning.
Borough Green & Wrotham station is on the line towards Maidstone and London, so plenty of residents commute. We can arrange a time to suit, collect a key if you will be out, and leave a note of when the bath or shower can be used again.
Village shops, the medical centre and lettings
The village centre has shops and businesses along the A25 and around the crossroads, each with kitchens, sinks and toilets that need resealing now and then. There is also a medical centre on Quarry Hill Road and a primary school. For any commercial or public building, out-of-hours working can be arranged so the facilities are not out of use during the day.
For landlords and letting agents with homes in Borough Green and the villages around it, we reseal between tenancies and after tenants report mould, and can quote for several properties together.

Questions from Borough Green
Do you cover all of Borough Green?
Yes. We cover the whole village and the parishes around it, including Wrotham, Platt, Ightham, Basted and Plaxtol.
The mastic on my windows near the A25 has gone black. Can it be cleaned?
Not usually. Once mastic has hardened and split, dirt is trapped in it. We cut it out and replace it with a flexible weatherproof sealant.
Can you reseal a bath in an older house where the walls are uneven?
Yes. We fill deeper sections properly, with backing rod where needed, so the finished bead looks even along the whole length.
I live in one of the newer houses on a former pub site. Why has the shower seal cracked?
New homes settle in their first year or two, and builder sealant often cannot cope. We cut it out and reseal with a flexible sanitary silicone.
Can you work while I am at work?
Yes. Many customers leave a key. We will lock up and leave a note with the cure time.
Do you reseal conservatory roofs and frames?
We reseal conservatory frames and the joints where they meet the house wall, where they can be reached safely. We will check access before quoting.
How soon can I use the kitchen sink?
Usually after the cure time we give you, often a few hours for light use. We will tell you before we leave.
