Outside joints around South Stoke
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Basildon Park (about 3.5 miles south) nearby, there’s older building stock in the area around South Stoke as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Cholsey station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St Andrew, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as South Stoke Primary School, larger buildings have long runs of movement joint that eventually need resealing.

External mastic in South Stoke, done properly
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. If you’re dealing with sealant pulling away from one side of the joint and brick movement joints where the sealant has split, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in South Stoke is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We stand behind the work with a 12-month guarantee.

Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
FAQs for South Stoke
Do you cover smaller places like South Stoke?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Cholsey station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
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.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. We will reseal it with a flexible sealant.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. In a small place like South Stoke, 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 depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

Aftercare tips
Looking after new joints is easy:
- Get split or bare joints resealed while the damage is small
- Leave the joints unpainted unless we’ve said otherwise
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like South Stoke, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Advice
What affects the quote in South Stoke
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Access and height
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
When you contact us, it’s useful to know:
- A few pictures by email, if you can
- Whether it has been sealed before
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
