About our external mastic in Easthampstead
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on concrete & block, brickwork movement joints and façade panels, and common reasons people get in touch are cracked joints where brick meets render or frames and weeds or debris growing in open joints.
In a smaller place like Easthampstead, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

How to look after the new joints
So the new joints stay in good condition:
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
- Clear growth from the base of walls and joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. A visit to Easthampstead is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

Advice
External mastic in Easthampstead: local notes
Easthampstead is part of Bracknell, one of the post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Michael and St Mary Magdalene's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Fox Hill Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.

When it is not the sealant
A few problems are outside what sealant work can do:
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.

When to call us in Easthampstead
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Look out for any of the following:
- Damp patches traced to an open external joint
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
If you let a flat or house near Bracknell station, split movement joints are easy to miss on a rental until damp shows inside.

- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- What product goes in the joint

What to tell us for a quote

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
FAQs for Easthampstead
Can you help a landlord with a rental near Bracknell station?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Easthampstead?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
