Expansion joint sealing near Langholm

Expansion joint sealing in Langholm, done properly

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we will confirm the choice in the quote. We work on precast concrete panel joints, podiums and floor movement joints and brickwork movement joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and sealant pulling off the joint face. For commercial sealant work in Langholm, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Travel to smaller places like Langholm is planned so the work is done in one trip where possible. Send photographs, joint widths and details of the traffic first.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • A joint that has to be widened or re-detailed before it can work
  • Cracking or settlement that calls for an engineer’s assessment
  • Proprietary pre-formed expansion joint systems

If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.

Slabs, ramps and loading bays in Langholm

Langholm is on Scotland’s drier eastern side. Freezing weather and salt still attack open external joints. Sealing them in drier months limits winter damage.

In a school such as Langholm Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Langholm: questions and answers

Do we have to stop operations in Langholm while the joints are sealed?

Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we will plan from there.

Is Langholm too small for you to travel to?

Not at all. Langholm is within our area. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Langholm, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Let us know about inductions and permits
  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send details through our quote form.

Related advice

Should maintenance staff do it?

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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Signs you need expansion joint sealing in Langholm

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.

Clients typically get in touch after noticing one or more of the following:

  • Weathered movement joint sealant that no longer flexes
  • Chipped joint edges on forklift routes
  • Car park joints leaking onto vehicles below
  • Expansion joints filled with dirt and stones

Sites like Thomas Hope Hospital, under half a mile to the south-east of Langholm, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Questions to ask before you book

  • Their public liability cover
  • Is the sealant right for the movement and the substrate?
  • What site paperwork they can supply
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Keeping the joints sound

A few simple habits keep the new joints working:

  • Raise snow-clearing blades over deck joints where possible
  • Keep product details with the building records for the next reseal
  • Plan racking layouts so feet don’t land on a joint
  • Clear dirt from joint lines during routine cleaning

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Surface by surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
