Resealing and mastic work across South Oxhey
Most homes in South Oxhey were built in a single burst after the Second World War, which means a lot of them now share the same problems at the same time: baths that have been replaced two or three times, shower trays fitted over old floors and window frames whose mastic has gone hard and grey. Mr Mastic travels to South Oxhey from our base in Crawley to put those joints right, inside and out.
We reseal baths, showers, basins, toilet bases and kitchen worktops, and we cut out and renew the sealant around windows and doors. The method never changes. Old silicone is removed completely, the joint is cleaned and dried, any mould is treated, and only then is a new bead applied and tooled. If a joint keeps failing because the surface behind it has moved or broken down, our remedial sealant work deals with the cause rather than covering it up.
An LCC estate built in six years
South Oxhey was laid out by the London County Council as an overspill estate on part of the old Oxhey Hall land. Work started in October 1946, the first residents moved in during November 1947, and building ran on until 1952, with the estate planned for around 3,850 homes. Ownership passed from the Greater London Council to Three Rivers District Council in 1980, and Right to Buy followed, so by 2007 roughly seven in ten houses were privately owned. The remaining council homes later moved to Thrive Homes.
That history shows in the bathrooms. Owner-occupied houses have usually been refitted by several different people, and we often find a new acrylic bath sealed over an older bead, or a shower tray set on a floor that flexes. Some of the estate was built with experimental prefabricated methods, and in those houses walls and floors can move differently from the fittings, so the sealant has to be flexible and properly bonded.
The centre of South Oxhey is now changing. Three Rivers and Countryside Properties agreed in 2016 to replace the old shopping precinct with a scheme of 514 new homes, shops and public space, built in phases from sites such as Hayling Road, Maylands and Ferndown Road, and Hallowes Crescent. Those newer flats and houses bring the usual first-years snags, which our new build mastic page explains.
Flats above shops, new blocks and estate terraces
Flats have always been part of South Oxhey, from the parades with homes above the shops to the new multi-storey blocks that have replaced the old precinct. In any flat, a split seal round a bath or shower can let water into the ceiling of the home below, so quick work matters. We can arrange access through Thrive Homes, a managing agent or the leaseholder, and we keep the work tidy in shared stairways.
Around the terraces and semi-detached houses, the outside jobs are mostly about replacement windows and doors. Frames fitted in the 1980s and 1990s were often sealed with mastic that has since shrunk away from the brick or render. We cut it out, add backing rod where the gap is deep and run a weatherproof bead that will move with the building. Streets near Oxhey Woods, with mature trees overhead, tend to need gutters and frames checked more often because of damp and leaf litter.
Landlords, housing providers and local shops
A large share of South Oxhey homes are rented, either from a housing association or from private landlords who bought former council houses. Our landlord sealant service fits around check-outs and new tenancies, and we can send photos of the finished work for your records.
We also reseal staff toilets, kitchens and washrooms for shops, cafés, surgeries and community buildings in and around the estate, and for small businesses in nearby Watford. Out-of-hours visits can be arranged so customers aren’t disturbed.

Your questions about mastic work in South Oxhey
Do you cover all of South Oxhey?
Yes. We cover the whole estate, the new homes in the town centre, Carpenders Park across the railway and the roads along the edge of Oxhey Woods.
My house was built by the LCC in the late 1940s. Does that change how you reseal?
It can. Older and prefabricated houses can move more than the fittings in them, so we use a flexible sanitary silicone and make sure the joint is fully clean and dry before sealing.
I rent from Thrive Homes. Can I book you myself?
Usually repairs go through your landlord first. If you own your home or lease a flat, you can book us directly.
I’ve moved into one of the new town centre flats and the shower seal is already cracking. Why?
New buildings settle in their first year or two, and builder sealant often can’t keep up. We cut it out, prime where needed and reseal properly.
Can you reseal a former council house before I let it out?
Yes. Landlords often book us between tenants so the bathroom and kitchen are sound before the new tenancy starts.
Do you replace mastic round uPVC windows on the estate?
Yes. We remove old, hardened mastic and apply a weatherproof sealant in white, brown or another colour to suit the frame.
How soon can I use the bath after resealing?
Usually after about 24 hours, depending on the product. We’ll tell you the exact cure time before we leave.
