External & façade joints in Nettlestone, Isle of Wight
Movement joints in Nettlestone need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Sealant pulling away from one side of the joint
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
How we handle external mastic in Nettlestone
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Common call-outs are for failed sealant between panels on a façade and movement joints filled with mortar instead of sealant, across joints between brick and frames, façade panels and concrete & block.
External sealant needs dry, clean surfaces, so work around Nettlestone is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a one-year guarantee, the same in Nettlestone as everywhere else we work.

What we are called out for in Nettlestone
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Joints with sealant missing in places
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
Homes close to St. Helen's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Nettlestone questions
Will you come out to Nettlestone?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect external mastic in Nettlestone?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will it make 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 does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email and tell us what needs doing and where.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
External mastic in Nettlestone: local notes
Nettlestone 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 landlords with property near Smallbrook Junction station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Nettlestone Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Nettlestone is about 2 miles east of Ryde, in the Isle of Wight.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Movement that is more than a sealant joint can take
- Damp that isn’t coming from the joint
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. In a small place like Nettlestone, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
How to get a quote

What affects the quote in Nettlestone
The price is agreed before any work begins. It takes into account:
- The amount of work
- The product the joint needs
- How many rooms, windows or areas are involved
- Access and height
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
What we need to know
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- The address or postcode of the job
- If someone has resealed it before
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Older cottages and farmhouses around Nettlestone can have timber 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. Call for a quick quote and we’ll talk you through it.

Surface by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Look over the joints every year, ideally after winter
- Leave the joints unpainted unless we’ve said otherwise
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
