About our external mastic in Hope End Green
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have old sealant gone brittle and cracked and failed seals between different materials, we can help.
Older homes in small places like Hope End Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, whatever its size.

Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.

What else we do in Hope End Green
Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Hope End Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Hope End Green buildings and the weather
With historic houses such as Barrington Hall (about 2.2 miles south-west) nearby, there’s older building stock in the area around Hope End Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Takeley Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of All Saints 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 Stansted Airport station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
