External & façade joints in Sheering, Essex
External mastic in Sheering from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
How we handle external mastic in Sheering
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. We work on concrete & block, render & cladding joints and brickwork movement joints, and the jobs we see most are movement joints with cracked, split or missing sealant and movement joints filled with mortar instead of sealant.
Around Sheering, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
A one-year guarantee comes as standard.

Why act early in Sheering
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. In a small place like Sheering, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Sheering buildings and the weather
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. With historic houses such as Barrington Hall (about 3.5 miles north-east) nearby, there’s older building stock in the area around Sheering as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Parish Church of St Mary the Virgin, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Hatfield Heath Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Sawbridgeworth station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Sheering questions
Is Sheering in your area for external mastic?
Yes. We work across London and the South East, and Sheering is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
I let a flat near Sawbridgeworth station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
What affects the cost of external mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- When we can work, for business premises
- The type of sealant required
- How many rooms, windows or areas are involved
No two jobs are quite the same, 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
To help us quote quickly, let us know:
- How we’d reach the joints
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
For external mastic in Sheering, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get split or bare joints resealed while the damage is small
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Avoid pressure-washing directly into sealant joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Sheering, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
How to get a quote
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Advice
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, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What we can’t put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
