External & façade joints in Oakley, Hampshire
Problem with your movement joints in Oakley? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Water getting into walls through failed joints
- Failed seals between different materials
- Leaking joints around cladding and façade panels
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
Give the sealant the cure time we tell you before anything rubs against it. 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. Resealing it early helps prevent that.
How we handle external mastic in Oakley
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. Typical jobs include sealant pulling away from one side of the joint and failed seals between different materials, on brickwork movement joints, concrete & block and joints between brick and frames.
Outbuildings, garages and conservatories around homes in places like Oakley add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
There’s a 12-month guarantee on every job, whatever its size.

Oakley: your questions answered
Do you cover smaller places like Oakley?

Yes, Oakley is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
What we are called out for in Oakley
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
The problems people usually mention when they call are:
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
Managing a site like Oakley CE Junior School? Then its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- Is the old sealant removed completely?
- Whether you can choose the colour
- How long the guarantee is
- When the joint can take water or movement

What else we do in Oakley
How we quote for external mastic
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- Whether the work is at height
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- The address or postcode of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Why it’s worth doing now in Oakley
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Homes in smaller places like Oakley can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
External mastic in Oakley: local notes
The South East is one of 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 Overton station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as St John's, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a job in Oakley, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
