Five Oak Green: your questions answered
Do you work for landlords with property near Paddock Wood station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is Five Oak Green in your area for external mastic?
Yes. We work across London and the South East, and Five Oak Green is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Should I point up the gap in my brickwork?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
External mastic in Five Oak Green, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. Common call-outs are for sealant pulling away from one side of the joint and weathered mastic that no longer stretches, across render & cladding joints, brickwork movement joints and concrete & block.
Around Five Oak Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
You get a one-year guarantee, the same in Five Oak Green as everywhere else we work.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Five Oak Green buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Paddock Wood station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Capel Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Homes close to Five Oak Green Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Deal with leaking gutters that soak the joints below
- Never let anyone fill a movement joint with mortar
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

What affects the quote in Five Oak Green
There’s no set price list. The quote depends on:
- The old material and how stubborn it is
- Working hours on commercial sites
- The size of the job
- The product the joint needs
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
How the visit works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Somewhere as small as Five Oak Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
