External mastic for homes and businesses in Five Oaks
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. If you have damp patches traced to an open external joint and plants rooting in failed movement joints, we can put it right.
Somewhere as small as Five Oaks, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
You get a one-year guarantee, the same in Five Oaks as everywhere else we work.

Why act early in Five Oaks
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Five Oaks, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the quote in Five Oaks
Call for a quick quote. What matters most is:
- Working hours on commercial sites
- How easy the joints are to reach
- The type of sealant required
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

What the job involves on each surface

Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.

Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.

What external mastic looks like in Five Oaks
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 The Weald School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Billingshurst station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
