External mastic in Westley: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Sparsholt Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St Stephen, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic for homes and businesses in Westley
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. Typical jobs include old sealant gone brittle and cracked and rain getting behind render or cladding at a joint, across façade panels, concrete & block and brickwork movement joints.
Somewhere as small as Westley, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee, whatever its size.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Movement that is more than a sealant joint can take
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Façade panels
- Copings & trims
When to call us in Westley
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
If you let a flat or house near Winchester station, split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Which colour the sealant will be
- The length of the guarantee
- Whether all the old sealant comes out first

FAQs for Westley
Do you work for landlords with property near Winchester station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Is Westley within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
How much does external mastic cost in Westley?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Do you work at height?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
How long does the job take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. In a small place like Westley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Aftercare tips
To keep the joints looking good and working properly:
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
What happens on the day
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Westley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
