External & façade joints in Shepherd's Green, Oxfordshire
Our applicators work in Shepherd's Green on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Movement joints filled with mortar instead of sealant
Why act early in Shepherd's Green
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Shepherd's Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Shepherd's Green: your questions answered
Will you come out to Shepherd's Green?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do external mastic in Shepherd's Green?
Yes. We work across London and the South East, and Shepherd's Green is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
How long will you be here?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Are you fully insured?
Yes. We’re fully insured.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Landlords, agents and businesses in Shepherd's Green
Housing providers, facilities teams and property managers book us too in Shepherd's Green and across Oxfordshire. Several sites can go on one quote.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
When something else is needed
In fairness, some problems need a different trade:
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Copings & trims
- Concrete & block
What we’re called out for in Shepherd's Green
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Keep an eye out for these signs:
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
If you let a flat or house near Henley-On-Thames station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- How much experience the applicator has
- How long to leave it before use
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building, and the area is left clean. Somewhere like Shepherd's Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Related advice
Shepherd's Green buildings and the weather
With historic houses such as Greys Court (about 0.7 miles east) nearby, there’s older building stock in the area around Shepherd's Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Peppard Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
