External mastic in Staplefield
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. Typical jobs include joints pointed up with cement by mistake and sealant pulling away from one side of the joint, across brickwork movement joints, façade panels and copings & trims.
Somewhere as small as Staplefield, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
You get a 12-month guarantee, the same in Staplefield as everywhere else we work.

Walls and rooflines in Staplefield
With historic houses such as Tyes Place (about 0.4 miles east) nearby, there’s older building stock in the area around Staplefield 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.
For an older house near a landmark such as Church of St Mark, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like St Mark's CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Balcombe station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Staplefield is about 4 miles north-west of Haywards Heath, in West Sussex. Jobs in Staplefield get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 371 places across West Sussex.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we’ve said otherwise
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted and spoil the finish.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Staplefield 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.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

Why it’s worth doing now in Staplefield
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Staplefield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Staplefield questions

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 call 0345 464 0079 or email us.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you have insurance?
Yes, we’re fully insured for every job we do.
When it isn’t the sealant
It helps to know what we can’t do:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
Surfaces we seal
- Copings & trims
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Façade panels
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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.
