Walls and rooflines in Elmfield
Elmfield 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. With historic houses such as Nunwell House (about 2.6 miles south) nearby, there’s older building stock in the area around Elmfield as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Oakfield Church of England Aided Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around St John's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Elmfield is about 1 mile south-east of Ryde, in the Isle of Wight.

About our external mastic in Elmfield
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are sealant pulling away from one side of the joint and joints with sealant missing in places.
Homes around Elmfield range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
You get a one-year guarantee, the same in Elmfield as everywhere else we work.

What affects the quote in Elmfield
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- The size of the job
- Whether the work is at height
- When we can work, for business premises
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel

Your questions about external mastic in Elmfield
Is Elmfield within the area you cover?
Yes. Elmfield is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is external mastic in a coastal place like Elmfield 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 it messy?
No. The area is protected while we work and cleaned up afterwards.
What is backing rod for?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Act on the first splits you see
- Point out the joints to other trades
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Homes in smaller places like Elmfield can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
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.

The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. For a job in Elmfield, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
Before we arrive
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

Advice
Signs you need external mastic in Elmfield
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and make things worse.
Most people get in touch when they notice one of these:
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
- Panel joints letting water in
- Rigid filler in a joint that should flex
Letting a property close to Ryde St Johns Road station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Honest limits
Before booking, it’s worth knowing the limits:
- Cracked brickwork or render that needs a builder or plasterer
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall

What we seal
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Render & cladding joints
- Façade panels
Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.
