External & façade joints in Newbridge, Isle of Wight
Professional external mastic in and around Newbridge, with every bit of old sealant taken out first and a 12-month guarantee.
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
Do you need external mastic in Newbridge?
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
Schools such as Shalfleet Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How we handle external mastic in Newbridge
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. Typical jobs include failed sealant between panels on a façade and joints where the bead has come unstuck, on joints between brick and frames, brickwork movement joints and façade panels.
Somewhere as small as Newbridge, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, in Newbridge and everywhere else we cover.

Newbridge: your questions answered
Is external mastic in a coastal place like Newbridge any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Newbridge in your area for external mastic?
Yes, Newbridge is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Newbridge buildings and the weather
Newbridge is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Swainston Manor (about 1.8 miles east) nearby, there’s older building stock in the area around Newbridge as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Church of St. Michael the Archangel, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Newbridge, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs 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
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or send us an email.

Looking after it afterwards
To keep the joints looking good and working properly:
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
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.
What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around Newbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How the job changes by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Tell us what the building has when you get in touch.
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.
For landlords and businesses
Housing providers, facilities teams and property managers book us too in Newbridge and across the Isle of Wight. We can quote a run of properties together, and we’re fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
