External mastic in Selling
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. Typical jobs include moss and dirt in joints with no sealant left and water getting into walls through failed joints, on brickwork movement joints, concrete & block and façade panels.
External sealant needs dry, clean surfaces, so work around Selling is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall

FAQs for Selling
Is Selling within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Selling station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How do I get a quote for external mastic in Selling?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
What affects the quote in Selling
We quote each job individually. These are the things that affect it:
- The amount of work
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before any work starts.
Asking for a quote
To make quoting easier, please include:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- The rough size of the job
- If someone has resealed it before
To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Somewhere as small as Selling, 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.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
How to get a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
- Make sure movement joints are not pointed over
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
External mastic in Selling: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Belmont House and Gardens (about 3.4 miles west) are a reminder that the area around Selling has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Selling Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Selling station, split movement joints are easy to miss on a rental until damp shows inside.

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a small place like Selling, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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.

Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
