Why act early in Lindfield
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Around Lindfield, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Why book with us
- Quality sealants from Arbo and Everbuild
- We agree the colour with you first
- Any old sealant cut out fully, not covered over
- Anti-fungal sanitary silicone in wet areas
External mastic for homes and businesses in Lindfield
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have brick movement joints where the sealant has split and leaking joints around cladding and façade panels, we can help, whatever the surface.
Around Lindfield, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Every job comes with our 12-month guarantee.

When to call us in Lindfield
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
If you live in an older home near All Saints Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- How hidden problems are handled
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- How the colour is chosen
Surface by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Outside joints around Lindfield
Historic houses like Ockenden Manor (about 2.7 miles west) are a reminder that the area around Lindfield has older buildings as well as new. In older buildings, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Haywards Heath station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Lindfield Primary Academy, its movement joints, gutters and trims need looking after like any other building’s.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
