How we handle external mastic in Shanklin
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you are dealing with gaps where render, brick and frames meet and sealant that has lost its bond to the brick or render, we can help.
Houses in smaller places like Shanklin can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
Our work is backed for twelve months, in Shanklin and everywhere else we cover.

What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- The product the joint needs
- How many rooms, windows or areas are involved
- The amount of work
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.
Helping us quote
When you call or email, these details help:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- The type of property
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:
- Movement that’s more than a sealant joint can take
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Walls and rooflines in Shanklin
Shanklin is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces 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 Shanklin station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as St Blasius Shanklin CofE Primary Academy, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around St. Paul's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Your questions about external mastic in Shanklin
Is external mastic in a coastal place like Shanklin any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Shanklin station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. In an older home around Shanklin, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Parking around Shanklin 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 inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
