External & façade joints in Hurst Green, Surrey
Our applicators work in Hurst Green on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
DIY versus a professional finish
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
About our external mastic in Hurst Green
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on brickwork movement joints, copings & trims and joints between brick and frames, and common reasons people get in touch are leaking joints around cladding and façade panels and plants rooting in failed movement joints.
Outside joints can only be sealed when they’re dry, so work in Hurst Green is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, large or small.

How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a small place like Hurst Green, access is usually the main thing to plan. 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.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

- Adding movement joints to masonry that has none
- Render that is blown, hollow or coming away

Do you need external mastic in Hurst Green?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
Letting a property close to Hurst Green station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Comparing quotes
- When the joint can take water or movement
- How the colour is chosen
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Hurst Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

FAQs for Hurst Green
Is Hurst Green in your area for external mastic?
Yes, Hurst Green is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Hurst Green?
Yes. Hurst Green 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.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Do not let climbing plants root in the sealant
- Look over the joints every year, ideally after winter
- Point out the joints to other trades
- Wash walls gently around the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Outside joints around Hurst Green
Historic houses like Titsey Place (about 2.3 miles north) are a reminder that the area around Hurst Green 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Hurst Green Infant School? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Agatha's Hall, older walls, gutters and the joints where extensions meet them need a flexible sealant.
