Your local mastic man for Croxley Green
Croxley Green is a village of distinct streets, each from a different decade, which makes it an interesting place to work. A terrace in Dickinson Square, a 1930s semi on Baldwins Lane and a 1970s house on Windmill Drive all need resealing sooner or later, but each one fails in its own way. Mr Mastic covers the whole village from our base in Crawley.
We reseal baths, showers, basins and kitchens, replace window and door mastic and seal external joints. The method is always to remove the old sealant completely, clean and dry the joint and then lay a single, well-tooled bead. Our bath resealing page shows what that involves.
From Dickinson’s mill to Windmill Drive
John Dickinson built Croxley Mill beside the canal in 1830, and in the late 1880s houses were built around Dickinson Square for the people who worked there. The square has been a conservation area since 1995: small terraced cottages and larger semis in finely pointed brick with terracotta dressings, originally with timber sashes, though many have since been replaced. New Road holds the village’s main run of Victorian terraces, while Dickinson Avenue and Yorke Road have larger Victorian and Edwardian houses.
Between the wars the village filled out with council houses on Gonville Avenue in the 1920s and semis and bungalows along Baldwins Lane and Winton Drive into the 1930s. After 1945 came council housing at Grove Crescent and Owens Way, flat-roofed 1960s estates such as Dorrofield Close, and Windmill Drive in the 1970s.
Each era has its own weak spots. Period houses have frames and sills that move with the seasons, interwar and post-war homes often have bathrooms on their third or fourth refit with layers of old sealant, and flat-roofed 1960s homes tend to have joints around frames and panels that have been patched more than once.
Terraces, bungalows and flats near the station
In the terraces of New Road and Dickinson Square, rooms are small and bathrooms are often at the back, sometimes in a later extension. Poor ventilation means condensation sits on the sealant and mould follows, so we use anti-fungal sanitary silicone and suggest simple ways to keep the joint dry. Where original timber sashes remain, we can use a paintable sealant that suits the frame.
Croxley Green has a lot of bungalows, especially around Links Way and Sherbourne Way, and many are home to older residents. Where a bath has been swapped for a walk-in shower or wet room, the sealant needs to be right first time; see our wet room sealing page. In the blocks of flats near Croxley station, we can work with managing agents on access.
Croxley Park, schools and lettings
Croxley Park, the office campus off Hatters Lane between the village and Watford, has buildings full of staff kitchens, toilets and showers. We can plan commercial resealing early in the morning or out of hours so facilities aren’t out of use during the working day.
Croxley Danes School, built between 2017 and 2020, York House School and the village primaries have washrooms and changing areas that can be done in the holidays. With a Metropolitan line station on the doorstep, Croxley Green also has plenty of rented homes, and we reseal for landlords and letting agents between tenancies.

Questions we’re asked in Croxley Green
Do you cover all of Croxley Green?
Yes. We cover the whole village, from Dickinson Square, New Road and the Green to Baldwins Lane and Windmill Drive, plus nearby Watford, Rickmansworth and Sarratt.
I live in the Dickinson Square conservation area. Can you reseal my windows?
Yes, internally and externally where the frames can be reached. Changes to front windows and doors there are controlled, so we keep to like-for-like sealant work and use paintable products on timber.
Can you seal a walk-in shower in a bungalow?
Yes. We reseal walk-in showers and wet rooms with sanitary silicone suited to constant wetting.
My flat-roofed 1960s house has gaps around the window panels. Can you help?
Yes. We cut out old, patched sealant and replace it with a flexible, weatherproof sealant, using backing rod where the gap is deep.
Can you work at offices on Croxley Park out of hours?
Out-of-hours working can be arranged for commercial jobs so staff facilities stay available during the day.
The bathroom in my New Road terrace keeps getting mould. Why?
Small, poorly ventilated rooms keep the sealant damp. We remove the mouldy bead, treat the joint and use anti-fungal silicone, and airing the room after showers helps.
Do you work for landlords near Croxley station?
Yes. We reseal between tenancies and when tenants report mould or leaks.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
