Jobs vary more than people expect. What affects the quote:

- Working hours on commercial sites
- How easy the joints are to reach
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How we handle external mastic in Cuckfield
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 mortar or filler would crack. Common call-outs are for moss and dirt in joints with no sealant left and damp patches traced to an open external joint, on joints between brick and frames, render & cladding joints and copings & trims.
In and around Cuckfield, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before sealing.
When to call us in Cuckfield
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
Managing a site like Holy Trinity Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Outside joints around Cuckfield
With historic houses such as Ockenden Manor (about 0.4 miles south-west) nearby, there’s older building stock in the area around Cuckfield as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Holy Trinity Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Haywards Heath station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Cuckfield is about 2 miles north-west of Haywards Heath, in West Sussex. Jobs in Cuckfield get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Cuckfield is one of 371 towns and villages in West Sussex we cover. For nearby work, see our Crawley page (7 miles or so).

Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on the building in most cases. Parking around Cuckfield is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
