Frittenden buildings and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Headcorn station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. 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. For site and facilities teams at buildings such as Frittenden Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

External mastic for homes and businesses in Frittenden
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. We’re often asked to deal with joints where the bead has come unstuck and failed seals between different materials, on joints between brick and frames, concrete & block and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Frittenden is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall

Questions from Frittenden
Can you help a landlord with a rental near Headcorn station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Do you cover Frittenden for external mastic?
Yes, Frittenden is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Can I do it myself?
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, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What we do, step by step
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building. For a village or hamlet like Frittenden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Clear the area around the work
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Advice
Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
What affects the cost of external mastic
The price is agreed before any work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Whether there’s mould to deal with
- How much there is to do
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
When you contact us, it’s useful to know:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- The rough size of the job
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job.
How to look after the new joints
Looking after new joints is easy:
- Tell anyone working on the walls about the movement joints
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we have said otherwise
- Avoid pressure-washing directly into sealant joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal.

Why act early in Frittenden
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Around Frittenden, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
