- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.

External mastic in West Hendred
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. We work on brickwork movement joints, concrete & block and façade panels, and common reasons people get in touch are failed seals between different materials and sealant pulling away from one side of the joint.
Older homes in small places like West Hendred may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Whatever the size of the job, you get the same 12-month guarantee in West Hendred and across Oxfordshire.

Walls and rooflines in West Hendred
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Didcot Parkway station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
What affects the cost of external mastic
Jobs vary more than people expect. The main factors:
- The number and length of the joints
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Any access issues, like height or stairs
- What’s wrong with the joints now
If you’re in West Hendred and need external mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

What else we do in West Hendred
Signs you need external mastic in West Hendred
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Common reasons people contact us are:
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
Schools such as The Hendreds Church of England School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- Is VAT in the price?
- How the surfaces are prepared before sealing
- What product goes in the joint
- When the joint can take water or movement
Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like West Hendred, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why book with us
- 12-month guarantee on every job
- Homes, businesses and hotels
- We leave the area clean and tidy
- Colour agreed with you before work begins
Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:

Common questions in West Hendred

Can you do external mastic in West Hendred?

How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
What do you put in the joint?
The product depends on the job: 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 the joint between them must be flexible. We choose one that suits both surfaces.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
