About our external mastic in Ockley
A movement joint is only as good as its depth. 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 have movement joints filled with mortar instead of sealant and weeds or debris growing in open joints, we can put it right.
External sealant needs dry, clean surfaces, so work around Ockley is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
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.

Honest limits
We will not take on work that will not last, so these are the limits:
- Movement that’s more than a sealant joint can take
- Damp that is not coming from the joint
- Cracking across the wall rather than at a joint

Ockley buildings and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St John's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Ockley station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Ockley is about 6 miles north of Horsham, in Surrey. Whether you are in the middle of Ockley or further out, external mastic is available for homes and businesses alike, from flats and houses to offices and hotels. 395 places in Surrey are on our list, large and small. Crawley is on our list too, about 8 miles from Ockley.
Work in RH5 works the same way as everywhere else we cover. You’ll find streets such as Prideaux Gardens, Stane Street and Friday Street. Neighbouring places we cover for external mastic include Paynes Green (1 mile south), Capel (2 miles east), Forest Green (2 miles north-west), Coldharbour (2 miles north) and Kingsfold (3 miles south-east).

Landmarks near Ockley
We work in homes and buildings around Wallis Wood and The Cricketers Arms Public House and the streets around them. Ockley’s nearest station is Ockley station, about 1.2 miles east. A little further out are Horsham Hospital (5.5 miles south) and Abinger Castle (4.3 miles north-west). Not far away are Warnham LNR and Leith Hill.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
Ockley questions
I let a flat near Ockley station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Is Ockley within the area you cover?
Yes, Ockley is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Somewhere like Ockley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

- 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.

Advice
Why act early in Ockley
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Ockley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
