External & façade joints in Combe, Oxfordshire
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Combe and across Oxfordshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. In a small place like Combe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

External mastic in Combe, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. 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. If you have failed sealant between panels on a façade and sealant that has lost its bond to the brick or render, we can help.
In a village or hamlet like Combe, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, you get the same one-year guarantee in Combe and across Oxfordshire.

Do you need external mastic in Combe?
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
If you can see any of these, it’s time to have the joints looked at:
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
Managing a site like Combe CofE Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- What the quote includes, VAT included or not
- When the joint can take water or movement
- Who turns up on the day
- What happens if the job turns out different
When something else is needed
In fairness, some problems need a different trade:
- Movement that is more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

External mastic in Combe: local notes
With historic houses such as Blenheim Palace (about 1.9 miles east) nearby, there’s older building stock in the area around Combe as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For landlords with property near Combe 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 St Laurence's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How the visit works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. For a village or hamlet like Combe, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
