Surface by surface
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.
Expansion joint sealing in Walls, done properly
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1, and the bead is tooled so it grips the two faces alone. If you are dealing with water getting into the wall through a failed joint and layers of sealant in a movement joint, we can help. Facilities teams, main contractors and managing agents in Walls tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Travel to smaller places like Walls is planned so the work is done in one trip where possible. Send photos, joint widths and details of the traffic first.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. Where we can, we combine work around Walls with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Warn occupants and staff about the work
- Arrange parking or a loading space

Acting at the first split keeps the cost down. For buildings near Walls, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

We price every job individually. The main factors are:

- Removal of failed or old sealant
- Access and working height
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Joints that move: notes for Walls
Walls is within about 1 mile of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. For an island location such as Walls, work is planned around ferry crossings and the weather. Joint widths, lengths and the traffic over them help us bring the right fillers and sealants.
Once a joint near Walls opens up, grit and water get in and the edges start to break.
Walls is in the Shetland Islands. If you are looking for expansion joint sealing in Walls, we can help, as we do across the Shetland Islands. Our the Shetland Islands coverage takes in 63 places, large and small.

What we’re called out for in Walls
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Look out for the following:
- Debris jammed in movement joints
- Chipped joint edges on forklift routes
- Joints where the bead has lost adhesion
- Rain penetration at brick or block movement joints
Around Walls, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Questions about Walls
Can being near the sea in Walls affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do we have to stop operations in Walls while the joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
What causes movement joint sealant to fail?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first since each needs a different fix.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you guarantee expansion joint work?
A 12-month guarantee covers our workmanship and we hold public liability insurance. Regular sweeping and inspection help the joints last.
Can staff carry on working while you are here?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
