Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Will you come out to Steventon End?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
I’m a tenant. Can you help?

Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- Mould in or behind the old joints
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- The address or postcode of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or email us.
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Steventon End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

The process
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.

- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.

Should I try it myself first?
What a professional job adds is preparation and the right 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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
