Expansion joint sealing across Gourock

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When it isn’t the sealant

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

  • Waterproofing layers buried beneath the sealant
  • A joint that has to be widened or re-detailed before it can work
  • Concrete or masonry repairs along the arrises

If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think.

Where we work in Gourock

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

Expansion joint sealing in Gourock, 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. We work on cladding panel joints, precast concrete panel joints and blockwork control joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and hardened, cracked sealant on exposed facades. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Gourock is the same: the right product in a properly prepared joint.

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

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Travel to smaller Scottish places like Gourock is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • Point out parking and an unloading spot
  • Tell staff and tenants when we will be in
  • Point out any areas we must not close

Advice

Your questions answered

Is a smaller place like Gourock outside your area?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Inverclyde Royal Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you guarantee expansion joint work?

It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Which product is best for expansion joints?

We choose a sealant with a movement capability that suits the joint as set out in BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.

Do you reseal car park expansion joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

Slabs, ramps and loading bays in Gourock

Gourock lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Gourock is in the west of Scotland, the wetter side of the country. Open joints in car parks and yards let in more water than in drier areas. We wait for dry, workable days to seal them.

Sites like Inverclyde Royal Hospital (0.8 miles south-east of Gourock) carry ambulances, deliveries and visitors’ cars over their road and deck joints. Centres like Oak Mall (2.3 miles east of Gourock) have mall floors and service decks whose joints carry steady traffic.

Gourock is about 2 miles north-west of Greenock, in Inverclyde. Our applicators travel to Gourock for work on movement joints. Gourock is one of 19 places we cover in Inverclyde for movement joints. Our Glasgow page has more on work in that area (22 miles or so).

What we are called out for in Gourock

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.

Site and facilities staff are often the first to spot these:

  • Rain penetration at brick or block movement joints
  • Debris jammed in movement joints
  • Weathered movement joint sealant that no longer flexes
  • Expansion joints split through the centre of the bead

Schools such as Gourock High School have movement joints in their walls and floors that are easy to overlook.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Proof of insurance
  • The named product and why it was chosen
  • How the existing material will be dealt with

Choosing a commercial sealant contractor

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Cost factors for movement joints

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Which sealant the job calls for
  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • Clear photos of the problem areas
  • The postcode of the building
  • Any dates the work must fit around
  • Specification clauses that apply

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email us.

How the job changes by surface

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.
