Your questions about external mastic in Smith's Green
Is Smith's Green within the area you cover?
Yes, Smith's Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Stansted Airport station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building, including the preparation. Your quote will say how long we expect yours to take.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How do I get a quote for external mastic in Smith's Green?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
External mastic in Smith's Green
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on façade panels, joints between brick and frames and copings & trims, and the jobs we see most are weathered mastic that no longer stretches and water getting into walls through failed joints.
Older homes in small places like Smith's Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
- Leave the joints unpainted unless we have said otherwise
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What affects the quote in Smith's Green
There’s no set price list, because no two jobs are the same. What we look at:
- The product the joint needs
- Mould in or behind the old joints
- Any working-time requirements on site
- How many areas need sealing
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- The rough size of the job
- Whether it’s a home or a business
- Photos by email, if that is easy
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job, and pictures are welcome.
What we are called out for in Smith's Green
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
The problems people usually mention when they call include:
- Joints with sealant missing in places
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
Schools such as Takeley Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- When the joint can take water or movement
- Are they insured?
- Is the old sealant removed completely?
- The length of the guarantee
How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Smith's Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Mention any tricky access

What external mastic looks like in Smith's Green
Historic houses like Barrington Hall (about 2.6 miles south-west) are a reminder that the area around Smith's Green has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of the Holy Trinity include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Stansted Airport station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Smith's Green
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a small place like Smith's Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
