External & façade joints in Headington Quarry, Oxfordshire
Movement joints in Headington Quarry need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
When to call us in Headington Quarry
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
The most common problems we see are:
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
Managing a site like Headington Quarry Foundation Stage School? Then its movement joints, gutters and trims need looking after like any other building’s.

External mastic in Headington Quarry
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. If you have gaps where render, brick and frames meet and movement joints filled with mortar instead of sealant, we can put it right.
In and around Headington Quarry, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Quotes for external mastic in Headington Quarry
Your quote is based on your job. We look at:
- How easy the joints are to reach
- How many areas need sealing
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- If someone has resealed it before
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or send us an email.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access from start to finish. A visit to Headington Quarry is planned like any other: the time, the access and where to park are agreed in advance. 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.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.
Related advice
Headington Quarry buildings and the weather
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. With historic houses such as Holywell Manor (about 2 miles west) nearby, there’s older building stock in the area around Headington Quarry as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Holy Trinity Church 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 Oxford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Common questions in Headington Quarry
Will you come out to Headington Quarry?
Yes, Headington Quarry is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Headington Quarry in your area for external mastic?
Yes. We work across London and the South East, and Headington Quarry is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Looking after it afterwards
After the cure time, these simple habits help:
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Avoid pressure-washing directly into sealant joints
- Clear growth from the base of walls and joints
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.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
Why it’s worth doing now in Headington Quarry
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a smaller place like Headington Quarry, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
