External mastic in Broadbridge
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We work on render & cladding joints, concrete & block and brickwork movement joints, and people most often call us about failed sealant between panels on a façade and hard, crazed mastic that has stopped moving.
External sealant needs dry, clean surfaces, so work around Broadbridge is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Broadbridge: your questions answered
Can you help a landlord with a rental near Bosham station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Broadbridge?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Are you fully insured?
Yes. We’re fully insured.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Surface by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.

Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Cracked brickwork or render that needs a builder or plasterer
- Damp that is not coming from the joint
- Render that is blown, hollow or coming away
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.
Surfaces we seal
- Joints between brick and frames
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Copings & trims
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. A stiffer product can damage the joint edge as it fails. Around Broadbridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.

Broadbridge buildings and the weather
Broadbridge is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Rented homes near Bosham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Bosham Primary School, its movement joints, gutters and trims need looking after like any other building’s.

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- The product the joint needs
- Any working-time requirements on site
- Access and height
- How many rooms, windows or areas are involved
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
To help us quote quickly, let us know:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.
The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Broadbridge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Move anything stored near the joints

Advice
Do you need external mastic in Broadbridge?
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
Homes close to The United Reformed Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- What the cure time is
- Who does the work, and how experienced they are
- What guarantee comes with the work
- How hidden problems are handled
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
