External & façade joints in Preston, Kent

Common problems we fix in Preston
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
People generally contact us after spotting something like this:
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
Letting a property close to Faversham station? Then split movement joints are easy to miss on a rental until damp shows inside.

External mastic for homes and businesses in Preston
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. If you have weeds or debris growing in open joints and leaking joints around cladding and façade panels, we can put it right, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Preston add more joints to look after. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
What affects the cost of external mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- How much there is to do
- The type of sealant required
- How many rooms, windows or areas are involved
- Any working-time requirements on site
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
To help us quote quickly, let us know:
- A few photos by email, if you can
- Any access issues, like height or stairs
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a smaller place like Preston, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before any work starts.
Why us?
- Experience in homes, commercial sites and hotels
- White, clear, grey or another colour, product permitting
- Fully insured
- You choose the colour before work begins

What external mastic looks like in Preston
Preston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Belmont House and Gardens (about 3.3 miles south-west) are a reminder that the area around Preston has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to St Catherine's Church 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 The Abbey School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Preston is about 7 miles south-west of Whitstable, in Kent. Every kind of property in Preston can book us for external mastic, old or new, large or small. Every job comes with our 12-month guarantee. Across Kent, we cover 922 places, and Preston is one of them. We also work in Chelmsford, about 34 miles from Preston.
Work in ME13 is quoted and booked the same way as anywhere else. You will find streets such as Back Lane, Quay Lane and Park Road, all of which we cover. You will find Preston on the A2 and A251, so it’s easy for us to get to. We also cover the places around Preston: Faversham (1 mile north-west), The Brents (1 mile north), Davington (1 mile north-west), Ospringe (1 mile west) and Whitehill (1 mile south-west).

How it works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. Parking around Preston is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

Questions from Preston
Can you help a landlord with a rental near Faversham station?
Yes, we work for letting agents and landlords. You can phone 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.
Is Preston within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. Exterior sealants come in a good range of colours.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Damp that is not coming from the joint
- Movement that’s more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
