Expansion joint sealing in Carloway
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. Site teams most often ask us about debris jammed in movement joints and water dripping through deck or ramp joints, on podiums and floor movement joints, cladding panel joints and car park decks and ramps. Searching for sealant specialists in Carloway? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around smaller Scottish places like Carloway, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.

When to call us in Carloway
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
Site and facilities staff are often the first to spot these:
- Layers of sealant in a movement joint
- Chipped joint edges on forklift routes
- Brittle, chalky sealant on external joints
- Damp inside where a wall movement joint has failed
Around Carloway, each joint gets a filler or sealant matched to what crosses it and how much it moves.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Travel to smaller Scottish places like Carloway is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- First, the joints are inspected for width, movement and the type of failure.
- 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.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Let us know about inductions and permits
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions

Expansion joint sealing in Carloway: the local picture
Carloway sits close to the coast, within about 2 miles. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Being on an island, Carloway means planning around ferry times as well as the weather. Joint widths, lengths and the traffic over them help us bring the right fillers and sealants.
A joint near Carloway that has lost its sealant lets in water and grit, and the edges suffer next.

Carloway: questions and answers
Does a coastal location like Carloway affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do we have to stop operations in Carloway while the joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
Does the weather affect joint sealing?
Weather matters for any external joint: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks typically need a polyurethane, and the specification has the final say.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
- Whether the work must be split into stages
- Quantities, in metres or numbers
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.
Sending details for a quote
However big the job, the same details help:
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
- What the building is and how it’s used
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Different surfaces, different methods
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed.
