About our external mastic in Horton-cum-Studley
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you are dealing with cracked joints where brick meets render or frames and weeds or debris growing in open joints, we can help.
Older homes in small places like Horton-cum-Studley may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
All our work is covered by a one-year guarantee, wherever you are in Oxfordshire.

What we can’t put right

- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

How the visit works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere like Horton-cum-Studley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Mention any tricky access
- Keep children and pets away from the work area

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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, then guaranteed for a year.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Why it’s worth doing now in Horton-cum-Studley
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Horton-cum-Studley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.

Outside joints around Horton-cum-Studley
Historic houses like Boarstall Tower (about 2.2 miles north-east) are a reminder that the area around Horton-cum-Studley 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Islip station, split movement joints are easy to miss on a rental until damp shows inside.

What we are called out for in Horton-cum-Studley
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
It’s worth asking for a quote if you see:
- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
Homes close to Church of St Barnabas include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
