External Mastic in Little Horkesley
Movement joints in Little Horkesley need attention? We cut out the old, prepare the joints and apply the right sealant.
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
Why act early in Little Horkesley
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Little Horkesley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before work begins.

How we handle external mastic in Little Horkesley
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on façade panels, brickwork movement joints and concrete & block, and common reasons people get in touch are panel joints letting water in and hard, crazed mastic that has stopped moving.
Around Little Horkesley, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
We stand behind the work with a 12-month guarantee.

Different surfaces, different methods
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Outside joints around Little Horkesley
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Bures station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere as small as Little Horkesley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Mention any sign-in or site rules at work premises
How to get a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.
Advice
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Common questions in Little Horkesley
Can you do external mastic in Little Horkesley?
Yes. We work across London and the South East, and Little Horkesley is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
I let a flat near Bures station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you work at height?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
What affects the cost of external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- Mould in or behind the old joints
- How much there is to do
- How many rooms, windows or areas are involved
Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Do you need external mastic in Little Horkesley?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The problems people normally mention when they call include:
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
For an older house near a landmark such as Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain.
