About our external mastic in Milcombe
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We’re often asked to deal with brick movement joints where the sealant has split and sealant that has lost its bond to the brick or render, across brickwork movement joints, façade panels and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Milcombe is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Each job carries a 12-month guarantee, large or small.

FAQs for Milcombe
Do you work for landlords with property near Banbury station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you do external mastic in Milcombe?
Yes, Milcombe is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How much does external mastic cost in Milcombe?
Size, access and the old material all affect the cost. Call for a quick quote.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height and we will confirm how they can be reached safely.
Walls and rooflines in Milcombe
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Broughton Castle (about 2.2 miles north) nearby, there’s older building stock in the area around Milcombe as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Banbury station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Bloxham Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- Concrete & block
- Brickwork movement joints
- Copings & trims

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Clear growth from the base of walls and joints
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Milcombe
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In a small place like Milcombe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

- Each joint is checked and the colour of the new sealant agreed.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Surface by surface
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.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
