Walls and rooflines in East Shalford
With historic houses such as Chilworth Manor (about 0.9 miles east) nearby, there’s older building stock in the area around East Shalford as well as newer homes. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Tillingbourne Junior School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Shalford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St Thomas include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we handle external mastic in East Shalford
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. We work on façade panels, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are sealant that has lost its bond to the brick or render and moss and dirt in joints with no sealant left.
Around East Shalford, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.

What affects the cost of external mastic
Call for a quick quote. What matters most is:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- How easy the joints are to reach
Instead of a standard rate, 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.
Asking for a quote
When you contact us, these details help:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- If someone has resealed it before
- Roughly how big the job is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like East Shalford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Advice
Common questions in East Shalford
Do you cover smaller places like East Shalford?
Yes. East Shalford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover East Shalford for external mastic?

Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Do you do commercial work?

Can landlords and businesses book you?

How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Around East Shalford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?
- Anti-fungal silicone where joints get wet
- White, clear, grey or coloured to suit, where the product allows
- Neat joints and a tidy finish
- Trusted Arbo and Everbuild sealants

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep high-pressure jets off the joints
- Point out the joints to other trades
- Make sure movement joints are not pointed over
- Fix overflowing gutters above sealed joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
