Signs you need external mastic in Foscot
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
The problems people generally mention when they call are:
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Old sealant gone brittle and cracked
If you live in an older home near Church of St Leonard, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- How the colour is chosen
- How the joint is cleaned and prepared
- What insurance they hold
- Which sealant they’ll use, and why
External mastic in Foscot, done properly
For buildings in Foscot, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on copings & trims, joints between brick and frames and brickwork movement joints, and the jobs we see most are damp patches traced to an open external joint and leaking joints around cladding and façade panels.
Somewhere as small as Foscot, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
There’s a 12-month guarantee on every job.

Landlord and commercial work in Foscot
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
How we quote for external mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- The size of the job
- The type of sealant required
- Whether the work is at height
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that’s easy
- Whether it has been sealed before
- What’s wrong with the joints now
- Where the job is, and your postcode
Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or send us an email and describe the job.
When something else is needed
In fairness, some problems need a different trade:
- Walls that need new movement joints cut into them
- Render that is blown, hollow or coming away
- Movement that’s more than a sealant joint can take
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Look over the joints every year, ideally after winter
- Have failed joints looked at early
- Show decorators and builders where the movement joints are
- Keep movement joints as flexible joints, not mortar
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. In a small place like Foscot, access is generally 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.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Foscot buildings and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Chastleton House (about 4.4 miles north) nearby, there’s older building stock in the area around Foscot 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.
Rented homes near Kingham station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Bledington Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Foscot questions
Can you help a landlord with a rental near Kingham station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Foscot?
Yes. Foscot is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.
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.
