- Panel joints letting water in
- Rigid filler in a joint that should flex

When to call us in Steephill
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
If you let a flat or house near Shanklin station, split movement joints are easy to miss on a rental until damp shows inside.

How we handle external mastic in Steephill
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. We work on façade panels, brickwork movement joints and render & cladding joints, and people most often call us about plants rooting in failed movement joints and movement joints with cracked, split or missing sealant.
Outside joints can only be sealed when they’re dry, so work in Steephill is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job.

Landlord and commercial work in Steephill
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
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.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new 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 Steephill, 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.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

External mastic in Steephill: local notes
Steephill is within about 1 mile 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. With historic houses such as Rylstone Manor (about 3.2 miles north-east) nearby, there’s older building stock in the area around Steephill as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St. Alban-the-martyr, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as St Francis Catholic and Church of England Primary Academy, larger buildings have long runs of movement joint that eventually need resealing.

Common questions in Steephill
Is Steephill within the area you cover?
Yes, Steephill is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Shanklin station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Steephill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.
