Littleton Common External Mastic
Professional external mastic in and around Littleton Common, with old sealant always removed completely and a one-year guarantee.
- Weeds or debris growing in open joints
- Sealant pulling away from one side of the joint
- Damp patches traced to an open external joint
How we handle external mastic in Littleton Common
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you are dealing with damp patches traced to an open external joint and failed sealant between panels on a façade, we can put it right, on joints between brick and frames, façade panels and concrete & block alike.
Somewhere as small as Littleton Common, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, 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.

How we quote for external mastic
There’s no set price list. The quote depends on:
- The type of sealant required
- Any mould that needs treating
- When we can work, for business premises
- How many rooms, windows or areas are involved
Every job is a little different, 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.
What we need to know
What to tell us when you ask for a quote:
- How we’d reach the joints
- Whether it has been sealed before
- Roughly how big the job is
- Whether it’s a home or a business
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or drop us an email.
How the job changes by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Littleton Common needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Check the sealant is paintable before painting near it
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Damp that is not coming from the joint
- Subsidence or other structural problems
- Walls that need new movement joints cut into them
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

Littleton Common buildings and the weather
Historic houses like Hampton Court Palace (about 4.8 miles east) are a reminder that the area around Littleton Common has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Letting a property close to Upper Halliford station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Ashford CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Parish Church of St Matthew, the joints between older walls, newer extensions and the roofline need a sealant that can move.
