Foulford External Mastic
We cover Foulford for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.

- Movement joints filled with mortar instead of sealant
External mastic for homes and businesses in Foulford
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. Common call-outs are for movement joints with cracked, split or missing sealant and old sealant gone brittle and cracked, on copings & trims, brickwork movement joints and concrete & block.
Around Foulford, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We stand behind the work with a one-year guarantee.

Landlords, agents and businesses in Foulford
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
How it works
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Foulford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

How we quote for external mastic
Call for a quick quote. The main things that affect it are:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- The type of sealant required
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What we need to know
Photos help, but a description is a good start. Please mention:
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- The rough size of the job
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or drop us an email with the details, and pictures are welcome.
Keeping the joints in good condition
Aftercare is simple:
- Keep high-pressure jets off the joints
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Foulford questions
Can you do external mastic in Foulford?
Yes. Our work covers London and the South East, and Foulford is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
What guarantee comes with external mastic in Foulford?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on the building, including preparation and clearing up. We’ll confirm how long when we quote.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.

What else we do in Foulford
Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before sealing.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Foulford buildings and the weather
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. With historic houses such as Avon Tyrrell House (about 3.3 miles south) nearby, there’s older building stock in the area around Foulford as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common problems we fix in Foulford
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People normally contact us when they notice something like this:
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
If you look after a building such as Ringwood School Academy, larger buildings have long runs of movement joint that eventually need resealing.

- How hidden problems are handled
- What guarantee comes with the work
- How the joint is cleaned and prepared
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
