Expansion joint sealing for commercial buildings in Melby

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. If you are dealing with damp inside where a wall movement joint has failed and debris jammed in movement joints, we can help, on blockwork control joints, brickwork movement joints and precast concrete panel joints alike. A single leaking joint is often how a building in Melby first comes to us: we look at the rest while we are there and tell you what we find.

Travel to smaller places like Melby is planned so the work is done in one trip where possible. Photos, approximate widths and what uses the floor help us bring the right materials.

Every job we finish is backed by a 12-month workmanship guarantee, in Melby as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.

Warehouse floors and decks around Melby

The sea is no more than about 1 mile from Melby. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Being in the east of Scotland, Melby gets less rain than the west coast. Frost and winter road salt still work into open joints in car parks and yards. Autumn is a sensible time to seal them.

Once a joint near Melby opens up, grit and water get in and the edges start to break.

Melby is in the Shetland Islands. Melby sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our the Shetland Islands coverage takes in 63 places, large and small.

Work on movement joints is covered throughout ZE2, whatever the building. Just outside Melby, we also work in Sandness (1 mile south-east), Walls (6 miles south-east), Aith (10 miles east), Easter Skeld (11 miles south-east) and Brae (12 miles north-east). For island and remote sites, travel and materials need planning ahead, so the full address helps from the start.

After the work

Regular inspection catches problems early. Specifically:

  • Keep racking legs and heavy point loads off floor joints
  • Reopen bays and walkways only after the stated cure time
  • Include every elevation and deck joint in periodic inspections
  • Keep scrapers and ploughs from dragging across joint sealant

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

Signs you need expansion joint sealing in Melby

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.

If one of these sounds familiar, it’s time for a closer look:

  • Rain penetration at brick or block movement joints
  • Arrises breaking up along floor joints
  • Brittle, chalky sealant on external joints
  • Movement joints with split or torn sealant

For floors and slabs around Melby, the product is chosen for the traffic and the movement at each joint.

Questions to ask before you book

  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

What affects the price in Melby

A fixed quote reflects the actual work. It allows for:

  • The total length or number of joints
  • How much existing material needs removing
  • Location, for remote and island sites
  • Which sealant the job calls for

There’s no price list, since every building and every scope is different. Call for a quote.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • Any specification or named product
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building near Melby, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  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. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Concrete or masonry repairs along the arrises
  • Waterproofing layers buried beneath the sealant
  • Cracking or settlement that calls for an engineer’s assessment

If you’re not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer before you book.

Your questions answered

Does a coastal location like Melby affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

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

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Which product is best for expansion joints?

Whatever suits the joint and the specification. We name the proposed product in the quote so there are no surprises.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

What will the job cost?

Each job is quoted on its own details. To get one, phone 01277 525 020 or email a schedule or drawings with a description of the work.
