External mastic in Tarpots
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Common call-outs are for damp patches traced to an open external joint and leaking joints around cladding and façade panels, on brickwork movement joints, copings & trims and façade panels.
External sealant needs dry, clean surfaces, so work around Tarpots is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Your questions about external mastic in Tarpots
Do you work for landlords with property near Benfleet station?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Tarpots within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, large or small.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
External mastic in Tarpots: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St George include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as The Appleton School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Benfleet station? Then split movement joints are easy to miss on a rental until damp shows inside.

How it works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Somewhere as small as Tarpots, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

Quotes for external mastic in Tarpots
There’s no set price list, because no two jobs are the same. The quote depends on:
- The number of rooms or windows
- The type of sealant required
- The old material and how stubborn it is
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: 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
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job, and photos are welcome.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on

Why it’s worth doing now in Tarpots
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Older cottages and farmhouses around Tarpots can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Landlord and commercial work in Tarpots
We also work for property managers and facilities teams in Tarpots and across Essex. We can quote a run of properties together, and we are fully insured for the work.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
