External Mastic in Westbrook
Our applicators work in Westbrook on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
About our external mastic in Westbrook
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on render & cladding joints, façade panels and joints between brick and frames, and the jobs we see most are movement joints with cracked, split or missing sealant and weathered mastic that no longer stretches.
Houses in smaller places like Westbrook can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When something else is needed
A few problems are outside what sealant work can do:
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
- Façade panels
When to call us in Westbrook
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we are asked about most:
- Weeds or debris growing in open joints
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Failed seals between different materials
For an older house near a landmark such as Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
- What guarantee comes with the work
- What the cure time is
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the building. Parking around Westbrook is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Clear the area around the work

Advice
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.

Should I try it myself first?
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 tell us about it when you ask for a quote.
External mastic in Westbrook: local notes
Westbrook is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Quex Park (about 2.2 miles south-west) are a reminder that the area around Westbrook has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Margate station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Garlinge Primary School and Nursery are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Westbrook is about 1 mile west of Margate, in Kent. Our applicators cover external mastic for householders, landlords and businesses in Westbrook and the surrounding area. Across Kent, we cover 922 places, and Westbrook is one of them. Our Chelmsford page covers work nearby (45 miles or so).
Every address in CT9 is covered for external mastic, from the main roads to the quietest streets. Streets in the area include Bridge Road, Caxton Road and Albert Road, and we cover them all. We also cover the places around Westbrook: Garlinge (1 mile south-west), Margate (1 mile east), Westgate-on-Sea (1 mile west), Flete (2 miles south) and Westwood (2 miles south-east). We also work in nearby towns such as Canterbury (14 miles south-west), Ramsgate (4 miles south-east), Broadstairs (3 miles south-east), Whitstable (14 miles west), Deal (12 miles south) and Herne Bay (10 miles west).
Near you in Westbrook
Locally, jobs take us to homes and businesses close to Cinque Ports Public House and Hartsdown Academy. Westbrook has its own railway station: Margate station. Other landmarks nearby include Westwood Cross (2.3 miles south-east) and Queen Elizabeth the Queen Mother Hospital (1.3 miles south-east). For a walk, there’s Sandwich and Pegwell Bay.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we’ve said otherwise
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
Do not 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.
What affects the quote in Westbrook
You’ll get a clear quote before work begins. It takes into account:
- The size of the job
- The old material and how stubborn it is
- Working hours on commercial sites
- Access and height
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- The rough size of the job
- Whether it has been sealed before
- What’s wrong with the joints now
- How we’d reach the joints
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Common questions in Westbrook
Is external mastic in a coastal place like Westbrook any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Westbrook?
Yes, we do. 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.
Are you insured?
Yes. We are fully insured.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
