External & façade joints in Woodstock, Oxfordshire
Movement joints in Woodstock need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
How we handle external mastic in Woodstock
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We work on joints between brick and frames, façade panels and copings & trims, and people most often call us about cracked joints where brick meets render or frames and old sealant gone brittle and cracked.
Houses in smaller places like Woodstock can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What affects the quote in Woodstock
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- Working hours on commercial sites
- The type of sealant required
- Mould in or behind the old joints
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we will talk you through it.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Any access issues, like height or stairs
- If someone has resealed it before
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
Woodstock buildings and the weather
London and the South East are among the drier parts 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 Blenheim Palace (about 0.8 miles south-west) nearby, there’s older building stock in the area around Woodstock 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 Hanborough station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St Mary Magdalene include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Woodstock Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
What we seal
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Concrete & block
Questions from Woodstock
Can you help a landlord with a rental near Hanborough station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Woodstock?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
How do I get a quote for external mastic in Woodstock?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Do you have insurance?
Yes. We’re fully insured.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Tell us what the building has when you get in touch.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Parking around Woodstock is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
