Outside joints around Lower Beeding
Historic houses like Tyes Place (about 4.1 miles east) are a reminder that the area around Lower Beeding has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as The Parish Church of the Holy Trinity, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Horsham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

About our external mastic in Lower Beeding
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. Common call-outs are for joints pointed up with cement by mistake and weathered mastic that no longer stretches, across façade panels, copings & trims and render & cladding joints.
Around Lower Beeding, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Lower Beeding, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Clear the area around the work

What affects the cost of external mastic
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- How much there is to do
- Access and height
- The old material and how stubborn it is
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- If someone has resealed it before

Honest limits
Before you book, it’s worth knowing the limits:
- Adding movement joints to masonry that has none
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Where we work in Lower Beeding
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Concrete & block
- Render & cladding joints
- Copings & trims
Common problems we fix in Lower Beeding
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we’re asked about most:
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
Schools such as Holy Trinity CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- Is the old sealant removed completely?
- Whether they’re fully insured
- Is VAT in the price?
- How the surfaces are prepared before sealing
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Are you an approved applicator?

Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Why act early in Lower Beeding
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Lower Beeding, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
