External & façade joints in New Town, Oxfordshire
Professional external mastic in and around New Town, with every bit of old sealant taken out first and a one-year guarantee.
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
When something else is needed
New sealant can’t fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that is not coming from the joint
- Structural movement, which needs a surveyor or engineer
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on

How we handle external mastic in New Town
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. If you are dealing with gaps where render, brick and frames meet and rain getting behind render or cladding at a joint, we can put it right, whatever the surface.
Older homes in small places like New Town may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
Big or small, you get the same one-year guarantee.

Do you need external mastic in New Town?
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.
It’s worth asking for a quote if you see:
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Hard, crazed mastic that has stopped moving
If you live in an older home near St Stephen's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before you book
- The length of the guarantee
- How the surfaces are prepared before sealing
- Whether they’re fully insured
- What happens if they find a problem under the old sealant

- Any mould that needs treating
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

External mastic in New Town: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Basildon Park (about 1.4 miles north) nearby, there’s older building stock in the area around New Town 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.
Rented homes near Pangbourne station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Basildon C.E. Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Advice
Common questions in New Town
Do you cover smaller places like New Town?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Pangbourne station. Can you help?

How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How do I get a quote for external mastic in New Town?

How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we have said otherwise
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
We also work for property managers and facilities teams in New Town and across Oxfordshire. Several sites can be quoted together, and we’re fully insured for the work.
