Expansion joint sealing across Monreith

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

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Keep traffic off new joints until the cure time is up
  • Act on the first tear or lifting edge rather than waiting
  • Inspect movement joints alongside other routine building checks
  • Clear dirt from joint lines during routine cleaning

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

How we handle expansion joint sealing in Monreith

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. If you’re dealing with arrises breaking up along floor joints and sealant pulling off the joint face, we can help, on precast concrete panel joints, cladding panel joints and blockwork control joints alike. One point of contact handles commercial sealant work in Monreith from the first photographs to the final walk-round, whether it’s one building or several.

For floor or movement joints around smaller places like Monreith, we plan to finish in one visit where we can. Photos, approximate widths and what uses the floor help us bring the right materials.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Movement on a scale no sealant is meant to absorb
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Joints and surfaces we work on

  • Car park decks and ramps
  • Precast concrete panel joints
  • Blockwork control joints
  • Podiums and floor movement joints
  • Cladding panel joints
  • Brickwork movement joints

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. For a building near Monreith, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  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. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs
  • Tell staff and tenants when we’ll be in

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Your questions answered

Must our site in Monreith stop work while the joints are done?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

Is Monreith off your patch?

No. Small places get the same service as large ones. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.

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.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.

Traffic, movement and joints around Monreith

Monreith lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Monreith is on Scotland’s wetter western side. External slab joints left open take plenty of rain. We wait for dry, workable days to seal them.

Around Monreith, each joint gets a filler or sealant matched to what crosses it and how much it moves. Once a joint near Monreith opens up, grit and water get in and the edges start to break.

Monreith is about 22 miles south-east of Stranraer, in Dumfries and Galloway. We send applicators to Monreith for movement joints. We work across 139 places in Dumfries and Galloway. We also cover Glasgow, around 78 miles from Monreith.

What the job involves on each surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Cost factors for movement joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How accessible the joints are
  • The total length or number of joints
  • The site’s rules and procedures
  • Distance, for remote addresses

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • The asbestos register, for older buildings
  • Access details, including height
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
