Expansion joint sealing across Gullane

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

Expansion joint sealing for commercial buildings in Gullane

If you need expansion joint sealing in Gullane, start with photos and joint lengths. We will come and look where photos don’t show enough, then send a fixed quote that names the sealant. To discuss the joints first, call the office on 01277 525 020 or email the details over. If you have torn sealant in brick or block movement joints and rain penetration at brick or block movement joints, we can help, on blockwork control joints, podiums and floor movement joints and precast concrete panel joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Gullane is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For floor or movement joints around smaller places like Gullane, we plan to finish in one visit where we can. Send photos, joint widths and details of the traffic first.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. For work around Gullane, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  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. 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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why it’s worth doing now in Gullane

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Gullane before they leak.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What you get with us

  • Failed material removed, not covered up
  • A range of standard colours, depending on the product
  • Our applicators hold CSCS cards
  • Sealing commercial buildings since 2005

See how commercial sealant jobs are priced or our accreditations.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

How the job changes by surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Leaks coming from the membrane rather than the joint seal
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

Questions about Gullane

Is Gullane off your patch?

No. Small places get the same service as large ones. We work across every Scottish council area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is a hospital such as Edington Cottage Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

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.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Expansion joint sealing in Gullane: the local picture

Gullane sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. The east of Scotland, where Gullane is, gets less rain than the west. Frost and de-icing salt still find their way into open external joints. Sealing them in drier months limits winter damage.

Around Gullane, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Gullane is about 6 miles north of Haddington, in East Lothian. Any commercial site in Gullane is covered, whether it’s a single job or part of a planned programme. Across East Lothian, 48 places are covered, including Gullane. For work in that direction, see our Edinburgh page (16 miles or so).

What we’re called out for in Gullane

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

Look out for the following:

  • Chipped joint edges on forklift routes
  • Leaks through car park deck joints onto the level below
  • Rain penetration at brick or block movement joints
  • Hardened, cracked sealant on exposed facades

Sites like Edington Cottage Hospital (to the east of Gullane) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Before you book anyone

  • How the existing material will be dealt with
  • How the joint faces will be prepared and primed
  • Who will actually carry out the work
  • How joint depth will be controlled
