Need expansion joint sealing in Shader?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Record the sealant used and the date in the O&M file
  • Check joints after long freezing spells
  • Avoid parking heavy plant or pallets on joint lines
  • Keep scrapers and ploughs from dragging across joint sealant

Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it. A routine sweep is the simplest protection.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

How we handle expansion joint sealing in Shader

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors. If you’re dealing with torn sealant in brick or block movement joints and chipped joint edges on forklift routes, we can help. One point of contact handles commercial sealant work in Shader from the first photos to the final walk-round, for single jobs and planned programmes alike.

In smaller places such as Shader, the joints we are asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.

Work we carry out in Na h-Eileanan Siar comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Location, for remote and island sites
  • Any access equipment needed
  • Working within restricted access windows
  • The product specified

Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • Any dates the work must fit around
  • How the joints are reached, and at what height

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email us.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs near Shader are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Let us know about inductions and permits
  • Share the asbestos register for older buildings
  • Tell staff and tenants when we’ll be in

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment
  • Joints too narrow for the movement, which need redesigning by the engineer

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.

Expansion joint sealing in Shader: the local picture

With the shore within about 1 mile, Shader counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. Shader is on Scotland’s wetter western side. Open joints in external slabs take a lot of water. Outside joints are sealed in dry spells, so dates have some give.

A joint near Shader that has lost its sealant lets in water and grit, and the edges suffer next; we’ll tell you if the edges need repairing first.

Shader (Gaelic: Siadar) is in Na h-Eileanan Siar. Across the HS2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Na h-Eileanan Siar coverage takes in 87 places, large and small.

We take on movement joints across the HS2 postcode area, for business premises of every kind. We also cover Borgh (1 mile north-east), Barabhas (4 miles south-west), West Side (4 miles south-west), South Dell (7 miles north-east) and North Dell (8 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you give us a call on 01277 525 020 or email drawings and photos.

Common problems we fix in Shader

Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

What tends to prompt an enquiry:

  • Debris jammed in movement joints
  • Expansion joints split through the centre of the bead
  • Joints where the bead has lost adhesion
  • Weathered movement joint sealant that no longer flexes

In and around Shader, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What your quote should include

  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • How the existing material will be dealt with
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Shader: questions and answers

Can being near the sea in Shader affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. 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 Shader 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.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

What exactly is a movement joint?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

How long will the joint resealing take?

The metres of joint, the access and the amount of removal decide it. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
