Your local mastic man for Hailsham
Hailsham is the largest inland town in East Sussex, with around 8,500 homes, and most of them have been built since the Second World War. That means a lot of bathrooms and kitchens that are now on their second or third refit, and a lot of sealant that has quietly reached the end of its life. Mr Mastic covers Hailsham from our base in Crawley, resealing baths, showers, basins and worktops and renewing the mastic around windows and doors.
A typical visit is simple. We look at what has failed and why, cut out every trace of the old bead, treat any mould behind it and let the joint dry before a new line of sanitary silicone goes on. If black spots keep coming back on your shower seal, our page on anti-mould resealing explains what we do differently.
A market town that kept on growing
The old core of Hailsham is small. St Mary’s Church dates from the early 15th century, The Stone is thought to go back to around 1320, and the 1542 building in Market Street now holds the Town Council offices. The Grade II listed Hailsham Pavilion opened in 1921. Around this centre, private developers have built steadily since 1945, and the north of the town now runs right up to the Hellingly boundary, with large developments such as Welbury and Woodholm Farm and, just over the parish line, the Roebuck Park estate on the former Hellingly Hospital site.
For sealant, those decades show up in different ways. In the post-war and 1970s houses, acrylic baths that have been swapped in over the years often flex when full and tear a bead that was laid when the bath was empty. Kitchen worktops have shrunk back from the tiles, leaving a dark line where crumbs and damp collect. Replacement uPVC windows from the 1990s and 2000s now have mastic that has hardened and pulled away from the brick.
The newest homes are a different story. Builder sealant is often thin and laid before the house has settled, so cracks around shower trays and bath ends in the first year or two are common. Our guide to new build sealant snagging covers what to look for.
Family houses, flats over shops and plenty of frames
Most Hailsham jobs are in houses, where access is easy and we can usually park on the drive or the street outside. In the town centre, along the High Street, George Street and around the Quintins in North Street, there are flats above shops where the bathroom sits over a business. A failed shower seal there can mark a shop ceiling, so we take extra care to fill trays and baths before sealing and to leave the bead to cure properly.
Outside, the estates have a lot of windows, patio doors and conservatory frames. The joints facing south and west take the most sun and dry out first. We cut out the old mastic, clean the frame and brickwork, add backing rod where the gap is deep and finish with a flexible, weatherproof sealant in a colour that suits the frame.
Industrial estates, schools and rented homes
Light industry in Hailsham is based mainly on the two large estates west of the town, at Diplocks Way and Station Road, with smaller sites at Burfield Park and north of Old Swan Lane. Units like these have staff washrooms, kitchens and sometimes shower rooms, and we can reseal them out of hours so they are not lost during the working day. The town also has several primary schools, Hailsham Academy on Battle Road and Bede’s School nearby, all with washrooms that need attention from time to time.
With so much family housing, landlords and letting agents are a steady part of the work. We reseal between tenancies and can look at several properties in one visit.

Hailsham: common questions
Do you cover all of Hailsham?
Yes. We cover the whole town, from the High Street and George Street out to the northern estates, plus Hellingly, Horsebridge, Upper and Lower Dicker, Magham Down and Herstmonceux.
We bought on one of the newer estates in north Hailsham and the shower seal has split. Why?
New homes settle and builder sealant is often thin, so early cracking is common. We cut it out, prime where needed and reseal with a flexible sanitary silicone.
My acrylic bath keeps pulling away from the wall. Can that be fixed?
Usually, yes. We remove the old bead, fill the bath so it sits at its lowest, then reseal so the joint can move with it.
Can you work in a unit on Diplocks Way or Station Road before staff arrive?
Out-of-hours working can be arranged for commercial jobs, so washrooms and kitchens stay in use during the day.
I live above a shop on the High Street. Can you still reseal my bathroom?
Yes. We bring everything up ourselves and take care to leave the seal fully cured so nothing reaches the shop below.
Do you reseal conservatory and patio door frames?
Yes. We replace hardened mastic around uPVC, timber and aluminium frames with a flexible, weatherproof sealant.
How long should I leave the bath after resealing?
Usually around 24 hours. We will tell you the exact cure time for the product before we leave.
