- Gaps where render, brick and frames meet
- Sealant pulling away from one side of the joint
- Joints with sealant missing in places
Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
How we handle external mastic in Godstow
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We’re often asked to deal with joints with sealant missing in places and movement joints filled with mortar instead of sealant, on façade panels, brickwork movement joints and joints between brick and frames.
Somewhere as small as Godstow, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

Questions from Godstow
Do you work for landlords with property near Oxford Parkway station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Godstow in your area for external mastic?
Yes, Godstow is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
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.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Godstow buildings and the weather
With historic houses such as Holywell Manor (about 2.7 miles south-east) nearby, there’s older building stock in the area around Godstow as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Wolvercote Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Oxford Parkway station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

When to call us in Godstow
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Common reasons people contact us include:
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
In the older streets around Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Older cottages and farmhouses around Godstow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
Why book with us

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 one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

- The old material and how stubborn it is
- Whether there’s mould to deal with
- When we can work, for business premises

What to tell us for a quote
When you contact us, it’s useful to know:
- Where the property is
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height

How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Godstow, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- Mention if the joints have been sealed before
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
