Expansion joint sealing in Longforgan: the local picture

Longforgan is within about 2 miles of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Being in the east of Scotland, Longforgan gets less rain than the west coast. Frost and de-icing salt still find their way into open external joints. Sealing them in drier months limits winter damage.

Office parks like Dundee Technology Park, 2.6 miles to the east of Longforgan, have decks, ramps and clad elevations whose joints take movement every day. A healthcare site such as Royal Dundee Liff Hospital (to the north-east of Longforgan) depends on car parks, ramps and service yards whose joints take traffic all day.

Longforgan is about 6 miles west of Dundee, in Perth and Kinross. Looking for expansion joint sealing in Longforgan? We can help, as we do across Perth and Kinross. 114 places across Perth and Kinross fall within our area, Longforgan among them. Our Dundee page has more on work in that area.

Expansion joint sealing in Longforgan, done properly

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. Site teams most often ask us about weathered movement joint sealant that no longer flexes and damp inside where a wall movement joint has failed, across cladding panel joints, precast concrete panel joints and car park decks and ramps. A single leaking joint is often how a building in Longforgan first comes to us: we look at the rest while we are there and tell you what we find.

Weather windows decide external joint work around a place like Longforgan: dry faces and the right temperature are essential, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.

Work we carry out in Perth and Kinross comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we’ll come back to it.

When to bring in a specialist

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 where general trades tend to cut corners.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Leaks coming from the membrane rather than the joint seal
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

What we seal

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

Why it’s worth doing now in Longforgan

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. We cut out the old seal and prepare the faces every time. Around smaller places like Longforgan, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why us?

  • Colours confirmed for the specified product
  • One number for every site we cover
  • CHAS accredited
  • Over 20 years of commercial sealing

How a job runs

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 we finish with a walk round so the work can be signed off. Tell us who will meet us and how to get in at your building near Longforgan. We will confirm the plan with the fixed quote.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  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.

Getting the site ready

  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Work for main contractors and building owners

Whether you are 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. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

How the job changes by surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed, and we will tell you if any edges need repairing first.

Questions about Longforgan

Is hospital work, at somewhere like Royal Dundee Liff Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Longforgan off your patch?

Not at all. Longforgan is within our area. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

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: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Are you CHAS accredited?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
