External mastic for homes and businesses in Crowhurst
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have rain getting behind render or cladding at a joint and joints pointed up with cement by mistake, we can put it right, on render & cladding joints, joints between brick and frames and copings & trims alike.
External sealant needs dry, clean surfaces, so work around Crowhurst is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What external mastic looks like in Crowhurst
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. Historic houses like Chartwell (about 4.7 miles north-east) are a reminder that the area around Crowhurst 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.
If you let a flat or house near Godstone station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Around Crowhurst
Crowhurst’s nearest station is Godstone station, roughly 1.9 miles west. Well-known places in the area include Haxted Watermill Museum (2.1 miles south-east) and Bletchingley Castle (4.7 miles north-west). Open spaces near Crowhurst include Hedgecourt Lake and Botley Hill.
Aftercare tips
A little care helps the new joints last. We recommend:
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
What affects the quote in Crowhurst
Jobs vary more than people expect. What affects the quote:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How many areas need sealing
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Helping us quote
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- How many joints, rooms or windows are involved
- Whether it has been sealed before
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Do you need external mastic in Crowhurst?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
People generally contact us after spotting one of these:
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
Homes close to Church of St George include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before booking anyone
- How the joint is cleaned and prepared
- Whether they’re fully insured
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Different surfaces, different methods
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Crowhurst, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
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.
