What we do, step by step
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work normally takes a few hours to a few days, depending on the length of joint and the access. Parking around Binstead is generally 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.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

Advice
External mastic for homes and businesses in Binstead
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on concrete & block, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are movement joints with cracked, split or missing sealant and hard, crazed mastic that has stopped moving.
Around Binstead, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
Every job comes with our 12-month guarantee, wherever you are in the Isle of Wight.

Surface by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Why act early in Binstead
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Homes in smaller places like Binstead can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

Questions from Binstead
Can you help a landlord with a rental near Ryde Esplanade station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Binstead?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Where do you work from?
We work from Crawley. Our applicators cover Binstead.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Walk round the building once a year and look at the joints
- Act on the first splits you see
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Quotes for external mastic in Binstead
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- The number and length of the joints
- Access and height
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
To make quoting easier, let us know:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- If someone has resealed it before
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Outside joints around Binstead
Binstead is close to 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Holy Cross Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Binstead Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Ryde Esplanade station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work can’t fix
It helps to know what we can’t do too:
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
- Movement that is more than a sealant joint can take
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
