External mastic for homes and businesses in Southcote
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We work on joints between brick and frames, copings & trims and concrete & block, and the jobs we see most are old sealant gone brittle and cracked and damp patches traced to an open external joint.
Homes around Southcote range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Landlords, agents and businesses in Southcote
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. For a job in Southcote, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Advice
Southcote: your questions answered
Can you do external mastic in Southcote?
Yes. Our work covers London and the South East, and Southcote is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Southcote?
Yes. Southcote is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you have insurance?
Yes. We’re fully insured.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
What external mastic looks like in Southcote
With historic houses such as Mapledurham House (about 3.1 miles north) nearby, there’s older building stock in the area around Southcote 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Matthew's, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Manor Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Reading Green Park station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

What affects the quote in Southcote
We quote each job individually. This is what makes a difference:
- The type of sealant required
- The size of the job
- When we can work, for business premises
- How many areas need sealing
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
For external mastic in Southcote, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Leave it or put it right?
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. Around Southcote, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
