What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
About our external mastic in Winterbrook
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We are often asked to deal with rigid filler in a joint that should flex and gaps where render, brick and frames meet, on joints between brick and frames, copings & trims and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Winterbrook is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What happens on the day
The work is kept neat and contained to the joints we’re treating. The job normally takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Somewhere as small as Winterbrook, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive

What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Outside joints around Winterbrook
Historic houses like Brightwell Manor (about 2.7 miles north-west) are a reminder that the area around Winterbrook has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Cholsey Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Cholsey station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near St John the Baptist's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

FAQs for Winterbrook
Is Winterbrook within the area you cover?
Yes, Winterbrook is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Winterbrook for external mastic?
Yes. Our work covers London and the South East, and Winterbrook is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Tell us about the building and we’ll confirm what access is needed.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Where a wall is exposed, as many are in small places like Winterbrook, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep soil, plants and ivy away from the joints
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we have said otherwise
- Walk round the building once a year and look at the joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
