Expansion joint sealing for Greosabhagh sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Inspect exposed joints once the cold weather has passed
  • Put movement joints on the planned maintenance inspection round
  • Note which joints were done, when, and with what
  • Keep stones and debris out of open joint lines

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can call the office on 01277 525 020 or email the details over and send a picture.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

Expansion joint sealing in Greosabhagh

We cover the full range of movement joints: 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’ll confirm the choice in the quote. We work on cladding panel joints, podiums and floor movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are weathered movement joint sealant that no longer flexes and rain penetration at brick or block movement joints. A specialist sealant contractor works differently from a general builder: in Greosabhagh, that means joint design, primers and backing rod as standard.

Weather windows decide external joint work around a place like Greosabhagh: dry faces and the right temperature are essential, so dates have some give. Internal floors can be done whenever suits the site.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Tell us who will meet us and how to get in at your building near Greosabhagh. We’ll confirm the plan with the fixed quote.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

What affects the price in Greosabhagh

The price varies from site to site. Expect it to depend on:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Removal of failed or old sealant
  • The total length or number of joints

Pricing movement joints depends on quantities, condition and access. Call for a quote.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • Your programme or deadline
  • Whether the building will be occupied during the work

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

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

Where floor joints take the most wear near Greosabhagh

With the shore within about 1 mile, Greosabhagh 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. The west of Scotland, where Greosabhagh is, gets more rain than the east. Rainwater through open yard and deck joints is a bigger issue here than in the drier east. Dry spells are used for the external joints.

For floors and slabs around Greosabhagh, the product is chosen for the traffic and the movement at each joint. Once a joint near Greosabhagh opens up, grit and water get in and the edges start to break.

Greosabhagh is in Na h-Eileanan Siar. Any commercial site in Greosabhagh is covered, for single jobs and planned programmes alike. Our Na h-Eileanan Siar coverage takes in 87 places, large and small.

Anyone looking for expansion joint sealing in HS3 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Nearby places we also cover include Scadabhagh (1 mile east), Plocrapool (2 miles east), Drinisiadar (2 miles north-east), Miabhaig (2 miles north) and Direcleit (4 miles north) for movement joints. Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Questions we’re asked in Greosabhagh

Will our site in Greosabhagh have to close for joint sealing?

Normally not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Our building in Greosabhagh is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

What guarantee do you give on joint sealing?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What exactly is a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably, and the sealing method is much the same.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
