How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
- Point out the joints to other trades
- Keep high-pressure jets off the joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
External mastic in Chapel Row
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you are dealing with damp patches traced to an open external joint and joints with sealant missing in places, we can help.
Outside joints can only be sealed when they’re dry, so work in Chapel Row is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, whatever its size.

What the job involves on each surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.

Outside joints around Chapel Row
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Woolhampton C.E. Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Douai Abbey Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

- On commercial sites, let us know about site rules

When to call us in Chapel Row
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 can’t stretch and tears as soon as the joint widens.
Most people get in touch when they notice something like this:
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
If you let a flat or house near Midgham station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before booking
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- What the cure time is
- Is VAT in the price?
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
- Movement that’s more than a sealant joint can take
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
