When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
- 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’ll give you a straight answer before you book.
What we seal
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Façade panels
About our external mastic in Barton
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Typical jobs include damp patches traced to an open external joint and sealant pulling away from one side of the joint, on render & cladding joints, façade panels and copings & trims.
Around Barton, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

How it works
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take anything from a few hours to several days, depending on the building. A visit to Barton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules

Do you cover smaller places like Barton?
Yes, Barton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How do I get a quote for external mastic in Barton?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Different surfaces, different methods
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly where it can be done safely.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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. All the old material has to come out first.
Signs you need external mastic in Barton
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Look out for any of the following:
- Damp patches traced to an open external joint
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
In the older streets around Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

Barton buildings and the weather
Historic houses like Holywell Manor (about 2.3 miles west) are a reminder that the area around Barton has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Oxford station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Bayards Hill School? Then larger buildings have long runs of movement joint that eventually need resealing.

Quotes for external mastic in Barton
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- Whether the work is at height
- The number of rooms or windows
- When we can work, for business premises
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
For a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Around Barton, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
