Mastic and sealant work in Rickmansworth
Much of Rickmansworth was built on the back of the Metropolitan Railway. The town grew in the Victorian era and again in the 1920s and 1930s as part of Metro-land, and those interwar houses still make up a big part of the area today. Many have since been extended and refitted with larger showers, en suites and wet rooms.
Mr Mastic covers Rickmansworth and the wider Three Rivers district from our base in Crawley. We reseal showers, baths, kitchens and basins, renew window and door mastic and seal external joints. Where a home has several bathrooms, we can usually do them all in one visit, and we always remove the old sealant in full before anything new goes on.
From Metro-land semis to Moor Park’s planned estate
Moor Park is the clearest example of planned Metro-land. Moor Park Ltd began work on 288 acres in 1922, building outwards from Sandy Lodge Halt, now Moor Park station, until 1939, and starting again in 1954. The result is low-density detached two-storey houses with pitched roofs on spacious plots. It was designated a conservation area on 18 May 1995 and has an Article 4 Direction. Loudwater Estate and Batchworth Heath are also conservation areas, and Rickmansworth’s own town centre is another.
Larger houses like these often have three or four bathrooms, a walk-in shower and sometimes a wet room. Wet rooms rely on sound joints at the floor and wall junctions, because there is no tray to catch a leak; our wet room sealing page explains what we check. Showers with frameless glass need sealant at the base and wall channel that stays flexible and clean.
Mill End, Croxley Green and Maple Cross add a mix of interwar, post-war and later homes, and the town centre has modern flats and maisonettes. In those, the usual jobs are tired bath seals, shrunken kitchen joints and window mastic that has hardened in the sun.
Article 4 streets, canal-side flats and managing agents
An Article 4 Direction removes some permitted development rights, so in Moor Park and other controlled areas it’s worth checking before you change windows or doors. Replacing failed mastic like for like is usually straightforward, and we match the colour so it suits the frame.
The Grand Union Canal runs along the edge of the Aquadrome, and there are flats and houses close to it and to the River Colne. In blocks of flats, a shower leak can reach the home below quickly, so we can work with managing agents on access, parking and timings, and reseal at the first sign of a gap rather than waiting for a ceiling stain. In larger houses, en suites are often built over a kitchen or living room, so the same early attention saves a ceiling repair downstairs.
Schools, the Watersmeet and town-centre businesses
Rickmansworth has several large schools, including Rickmansworth School, St Clement Danes and St Joan of Arc, with changing rooms and washrooms that are best resealed in the holidays. Watersmeet, the council’s theatre in the town centre, and the cafés, restaurants and offices along the High Street all have toilets and kitchens that need attention from time to time. Our commercial sealant service can work out of hours.
We also work for landlords and letting agents, resealing between lets.

Questions we’re asked in Rickmansworth
Do you cover all of Rickmansworth?
Yes. We cover Batchworth and the town centre, Mill End, Moor Park, Loudwater, Croxley Green, Maple Cross and West Hyde, plus Chorleywood and Sarratt.
Can you reseal three bathrooms in one visit?
Usually, yes. Tell us how many rooms and what needs doing, and we’ll plan the day so everything is finished together.
Can you seal a wet room?
Yes. We seal the floor and wall junctions with flexible sanitary silicone, as there is no shower tray to catch a leak.
I live in Moor Park. Is window mastic affected by the Article 4 Direction?
Like-for-like resealing of existing frames is usually routine, but if you plan to change windows or doors it’s worth checking with Three Rivers District Council first.
Can you seal around frameless glass shower screens?
Yes. We seal the base and wall channel with a clear or colour-matched silicone, keeping the bead neat.
Do you work in schools during the holidays?
Yes. Holiday work lets the sealant cure fully before pupils return.
Will you deal with my managing agent?
Yes. We can arrange access, parking and timings directly with them.
Water is escaping at the bottom corner of my shower screen. Is it the sealant?
Very often, yes. The corner where tray, wall and screen meet takes the most wear, and once the bead lifts there water runs behind it. We cut it out and reseal the whole run so the joint is continuous.
