External mastic in Goddard's Green, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We work on façade panels, joints between brick and frames and brickwork movement joints, and people most often call us about damp patches traced to an open external joint and joints pointed up with cement by mistake.
Around Goddard's 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.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
After the cure time, these simple habits help:
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Keep high-pressure jets off the joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Can I do it myself?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Signs you need external mastic in Goddard's Green
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
These are the problems we’re asked about most:
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
For site and facilities teams at buildings such as Garland Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- What the cure time is

How do I get a quote for external mastic in Goddard's Green?

Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Goddard's Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- 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 tricky access
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Advice
What external mastic looks like in Goddard's Green
Historic houses like Stratfield Saye House (about 3.7 miles south-east) are a reminder that the area around Goddard's Green has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Rented homes near Mortimer station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Stratfield Saye House, about 3.7 miles south-east, is one of the historic houses in the wider area around Goddard's Green.

What affects the quote in Goddard's Green

- Whether there’s mould to deal with
- Whether the work is at height
- The number and length of the joints
- Any working-time requirements on site
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.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- The rough size of the job
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Goddard's Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
