Balscote External Mastic
Problem with your movement joints in Balscote? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Weathered mastic that no longer stretches
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
What sealant work cannot fix
We will always be straight with you, so here’s what sealant cannot fix:
- Subsidence or other structural problems
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.
Joints and surfaces we work on
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
How we handle external mastic in Balscote
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We’re often asked to deal with leaking joints around cladding and façade panels and failed seals between different materials, across copings & trims, joints between brick and frames and façade panels.
Outside joints can only be sealed when they’re dry, so work in Balscote is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work comes with our one-year guarantee.

How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
Should I try it myself first?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Common problems we fix in Balscote
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The most common problems we see are:
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
Homes close to Church of St Mary Magdalene include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What else we do in Balscote
Balscote: your questions answered
Is Balscote within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do external mastic in Balscote?
Yes. We work across London and the South East, and Balscote is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Balscote buildings and the weather
Rainfall in the South East is lower than in much 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 Upton House (about 2.8 miles north-west) nearby, there’s older building stock in the area around Balscote 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.
If you let a flat or house near Banbury station, outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Act on the first splits you see
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the 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.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
For landlords and businesses
We also work for property managers and facilities teams in Balscote and across Oxfordshire. We can quote a run of properties together, and we’re fully insured.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Somewhere as small as Balscote, access is often the only tricky part. 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.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
