Do you need external mastic in Didling?
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.
These are the problems we are asked about most:
- Old sealant gone brittle and cracked
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
If you live in an older home near Church of St Andrew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

About our external mastic in Didling
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include sealant pulling away from one side of the joint and cracked joints where brick meets render or frames, across concrete & block, copings & trims and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Didling is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, in Didling and everywhere else we cover.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
- Have failed joints looked at early
- Check external joints each spring
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

Why act early in Didling
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a small place like Didling, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Old sealant always removed completely
- Every job guaranteed for a year
- A choice of colours where the product allows
- Tidy, careful work

What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Walls and rooflines in Didling
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. Historic houses like Uppark (about 3.7 miles west) are a reminder that the area around Didling has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Didling, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
