External mastic for homes and businesses in East Cowes
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include gaps where render, brick and frames meet and brick movement joints where the sealant has split, on render & cladding joints, concrete & block and copings & trims.
In and around East Cowes, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
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.

East Cowes buildings and the weather
East Cowes 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 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Isle of Wight Studio School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as St James's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Loose or hollow render, which needs re-rendering
- Damp that isn’t coming from the joint
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a smaller place like East Cowes, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In an older home around East Cowes, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

- Anti-fungal sanitary silicone in wet areas

East Cowes: your questions answered
Is East Cowes within the area you cover?
Yes, East Cowes is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does the coastal weather in East Cowes affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- Any working-time requirements on site
- The size of the job
- Whether there’s mould to deal with
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What we need to know
Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- Where the property is
- The rough size of the job
We quote each job on its own. Simply phone 0345 464 0079 or send us an email and describe the job and send photos if you have them.
