Outside joints around Sandhurst
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St George's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Sandhurst station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Sandhurst School? Then its movement joints, gutters and trims need looking after like any other building’s.

External mastic in Sandhurst, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We’re often asked to deal with movement joints with cracked, split or missing sealant and leaking joints around cladding and façade panels, across façade panels, concrete & block and render & cladding joints.
Sandhurst mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Quotes for external mastic in Sandhurst
Call for a quick quote. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- Which sealant suits the joint
- How many areas need sealing
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
What we need to know
To help us quote quickly, let us know:
- A few photos by email, if you can
- The type of property
- Access, such as stairs, a lift or height
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Common questions in Sandhurst
What guarantee comes with external mastic in Sandhurst?
All our work, in Sandhurst and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do external mastic in Sandhurst?
Yes. We work across London and the South East, and Sandhurst is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or email us.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Can you reach joints on upper floors?
It depends on the building. Send us photos and a rough idea of the height, and we will confirm what access is needed.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Aftercare tips
Looking after new joints is easy:
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
- Leave the joints unpainted unless we have said otherwise
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. In Sandhurst, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. In Sandhurst, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Keep children and pets away from the work area
