About our external mastic in Vernham Street
On houses, flats and commercial buildings across Vernham Street, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you are dealing with moss and dirt in joints with no sealant left and damp patches traced to an open external joint, we can help.
Outside joints can only be sealed when they’re dry, so work in Vernham Street is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, it’s backed by our 12-month guarantee.

How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Vernham Street, 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.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Related advice
What we’re called out for in Vernham Street
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and make things worse.
These are the problems we’re asked about most:
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
In the older streets around Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- When the joint can take water or movement
- Are they insured?
- How the colour is chosen
- What the quote includes, VAT included or not
When something else is needed
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Movement that’s more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that isn’t coming from the joint
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Brickwork movement joints

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
External mastic in Vernham Street: local notes
Historic houses like Stargroves (about 4.2 miles north-east) are a reminder that the area around Vernham Street 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Vernham Dean Gillum's Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Common questions in Vernham Street
Is there a guarantee on external mastic in Vernham Street?
All our work, in Vernham Street and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you come out to Vernham Street?
Yes, Vernham Street is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Are you fully insured?
Yes. Full insurance covers our work.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around Vernham Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
