External & façade joints in Havenstreet, Isle of Wight
Movement joints in Havenstreet need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Water getting into walls through failed joints
- Movement joints filled with mortar instead of sealant
- Weathered mastic that no longer stretches
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
External mastic in Havenstreet
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you’re dealing with movement joints filled with mortar instead of sealant and weeds or debris growing in open joints, we can put it right, on render & cladding joints, joints between brick and frames and brickwork movement joints alike.
Around Havenstreet, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Common problems we fix in Havenstreet
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The most common problems we see are:
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
Letting a property close to Smallbrook Junction station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

FAQs for Havenstreet
Do you work for landlords with property near Smallbrook Junction station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Is external mastic in a coastal place like Havenstreet any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.
How much does external mastic cost in Havenstreet?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
- Render that’s blown, hollow or coming away
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Façade panels
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
- Wash walls gently around the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere as small as Havenstreet, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Advice
What external mastic looks like in Havenstreet
Havenstreet 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’s hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Ryde Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St. Peter's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Havenstreet is about 2 miles south-west of Ryde, in the Isle of Wight. For external mastic in and around Havenstreet, it’s easy to get a quote: please call 0345 464 0079 or drop us an email.

Why act early in Havenstreet
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Havenstreet can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What the job involves on each surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
