External mastic in Wexham Court, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Typical jobs include moss and dirt in joints with no sealant left and joints where the bead has come unstuck, across render & cladding joints, façade panels and copings & trims.
External sealant needs dry, clean surfaces, so work around Wexham Court is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, whatever its size.

How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Wexham Court, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children

Wexham Court buildings and the weather
Historic houses like Windsor Castle (about 3.4 miles south) are a reminder that the area around Wexham Court 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. London and the South East are among the drier parts 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 Wexham School, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Parish Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Do you need external mastic in Wexham Court?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Signs it’s time to call us include:
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
Rented homes near Slough station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Older cottages and farmhouses around Wexham Court can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.

What affects the quote in Wexham Court
There’s no set price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How many areas need sealing
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- Where the property is
- What’s wrong with the joints now
- The type of property
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we will take it from there.
Wexham Court questions
Can you help a landlord with a rental near Slough station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can you do external mastic in Wexham Court?
Yes. Our work covers London and the South East, and Wexham Court is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall and the joint fails. If it has already been filled, we can usually cut it out and reseal it.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
