Mastic and sealant work in Ealing
Ealing has long been called the “Queen of the Suburbs”, and the name still suits its tree-lined streets of Victorian and Edwardian houses. Mr Mastic travels up from our base in Crawley to work right across the borough, resealing baths, showers and kitchens, renewing tired window mastic and sealing external joints on houses, flats and commercial buildings.
The borough is really seven districts in one: Ealing itself, Acton, Hanwell, Greenford, Perivale, Northolt and Southall. Each has its own mix of homes, and each brings its own sealant problems, from shrinking beads around a refitted bath in a Hanwell terrace to cracked joints in a brand-new Acton flat. Whatever the job, we take the old sealant out completely, clean and prepare the joint properly and finish with a neat, flexible bead that is made to last. You’ll know what the work involves and what it costs before we start.
Garden suburbs, 1930s semis and regeneration blocks
Much of central Ealing and Acton was built up in the late Victorian and Edwardian years, and the borough has 30 conservation areas. Two of its well-known corners are garden suburbs: Brentham Garden Suburb, begun in the early 1900s, and the Ealing side of Bedford Park, the red-brick Queen Anne Revival estate started in 1875 that straddles the boundary with Hounslow. In houses like these, original timber sash windows are common, and the old putty and mastic around the frames dries out and cracks with age. Our guide to sand mastic on sash windows explains why the right product matters on period frames.
Further west, Perivale, Greenford and Northolt grew quickly between the wars, once Western Avenue and new rail links opened them up. Perivale was almost all farmland in 1921, and its three-bedroom houses with gardens were built for the workers at factories such as the Hoover Building, whose upper floors have since been turned into flats. In these 1930s homes the bathroom has usually been refitted more than once, and we often find layers of old sealant, or uPVC replacement windows whose mastic has hardened and lifted.
At the other end of the scale is South Acton, the borough’s largest estate, which is being rebuilt as Acton Gardens with nearly 3,500 new homes. New flats settle in their first few years, and the developer’s sealant in showers and kitchens often splits as they do.

Working in Ealing’s flats and conversions
A large share of Ealing’s Victorian and Edwardian houses have been split into flats, so a failed shower seal on the first floor quickly becomes a stained ceiling for the flat below. We work carefully in shared hallways, keep dust and mess to a minimum and can liaise with a managing agent or building owner if they need to approve the work. In the conservation areas, we keep to slim, neat beads and colours that suit painted timber, so the frames still look right from the street.
In the newer blocks around Acton Gardens and Southall, access is usually the main thing to plan: parking bays, lift bookings and fob entry. Tell us about the building when you book and we’ll arrange the visit around it, so the job runs smoothly on the day.
Park Royal, healthcare and rented homes
Park Royal, shared between Ealing and Brent, is described as the largest business park in London, with more than a thousand firms, many of them food businesses. Kitchens, welfare blocks and staff washrooms in sites like these need hygienic sealant that can be cleaned hard and renewed when it fails. Ealing Hospital in Southall and the University of West London’s Ealing site also sit within the borough, alongside many care homes, clinics and schools; our healthcare sealant page covers anti-bacterial products and working around patients and staff.
Ealing also has a large rented sector. We help landlords and letting agents with resealing between tenancies and when tenants report mould or leaks.

What we do in Ealing
- Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
- Window & door mastic: Window and door mastic that has dried out in the sun replaced with a weather-resistant joint that can move with the frame.
- Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.
- Remedial sealant & repairs: Second opinions on sealant that keeps failing: we strip it out, check for movement or leaks and reseal it properly.
- Fire-rated sealant: Gaps in fire-separating walls and floors sealed with fire-rated products, following the tested details for each one.
- External & façade joints: Outside movement joints given new backing rod and a flexible, weatherproof sealant in a colour to match the wall.
- New-build mastic & snagging: Snagging sealant for new homes and plot-by-plot mastic for builders and developers.
- Floor & skirting joints: Movement joints in tiled and concrete floors, and skirting gaps, sealed so they stay tidy and keep dirt out.
- Regrouting: Shower and splashback grout replaced where it has cracked or stained, with silicone in the movement joints.
- Glazing & conservatory sealant: Glass-to-frame joints on conservatories, rooflights and shower screens cut out and resealed.
- Gutter, fascia & soffit sealing: Exterior joints at gutters, fascias and soffits resealed to stop drips and staining down the wall.
- Sand mastic for sash & case windows: Traditional sand mastic for period windows and doors where a modern sealant would look out of place.

Questions from Ealing
Do you cover all of Ealing?
Yes. We work across the whole borough, including Ealing Broadway, Acton, Hanwell, Greenford, Perivale, Northolt and Southall.
I live in a conservation area. Can you reseal my sash windows?
Yes. We cut out the old, cracked mastic and use a product and colour suited to painted timber, keeping the bead slim and neat.
My Acton Gardens flat is only a few years old and the shower sealant has split. Why?
New buildings settle and showers get daily use, so developer sealant often fails early. We remove it, prime where needed and reseal with sanitary silicone.
Our 1930s Perivale bathroom has several layers of old sealant. Can you sort it?
Yes. We strip every old layer back to a clean surface before resealing, because new silicone won’t bond properly to old.
Can you work in a food business on Park Royal?
Yes. We use hygienic, anti-bacterial sealants for kitchens and washrooms, and out-of-hours visits can be arranged.
Do you work for Ealing letting agents?
Yes. We reseal between tenancies and can deal directly with the agent to arrange access.
How soon can I use my bath after resealing?
Usually after around 24 hours. We’ll confirm the cure time for the product we used before we leave.
