Expansion joint sealing across Port Logan

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

Expansion joint sealing in Port Logan

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 previous reseals laid over old sealant and rain penetration at brick or block movement joints, on podiums and floor movement joints, cladding panel joints and blockwork control joints. Most enquiries from Port Logan start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

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

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we will arrange a return visit.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For work around Port Logan, 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. We assess the joints on site or from photos, noting widths and how each has failed.
  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. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

Advice

Expansion joint sealing around Port Logan: how the place shapes the job

Port Logan is within about 1 mile of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Port Logan is on Scotland’s wetter western side. External slab joints left open take plenty of rain. Dry spells are used for the external joints.

A joint near Port Logan that has lost its sealant lets in water and grit, and the edges suffer next; we will tell you if the edges need repairing first.

Port Logan is about 13 miles south of Stranraer, in Dumfries and Galloway. Anywhere in DG9, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 139 places across Dumfries and Galloway fall within our area, Port Logan among them.

We cover the DG9 postcode districts for movement joints. We also cover Ardwell (3 miles north), Drummore (3 miles south-east), Sandhead (6 miles north), Stoneykirk (8 miles north) and Lochans (10 miles north) for movement joints.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

When to call us in Port Logan

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. The product has to be suited to the traffic.

Look out for the following:

  • Water dripping through deck or ramp joints
  • Expansion joints filled with dirt and stones
  • Joints where the bead has lost adhesion
  • Brittle, chalky sealant on external joints

For floors and slabs around Port Logan, the product is chosen for the traffic and the movement at each joint.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?
  • How they’ll work around occupants
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

Port Logan: questions and answers

Must our site in Port Logan 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. The phasing plan comes with the quote.

Can being near the sea in Port Logan affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you use silicone or polyurethane in movement joints?

Whatever suits the joint and the specification. We name the proposed product in the quote.

Why has the sealant in our expansion joints split?

The way it has failed typically tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.

What we can’t put right

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

  • Proprietary pre-formed expansion joint systems
  • A joint that has to be widened or re-detailed before it can work
  • Cracking or settlement that calls for an engineer’s assessment

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Joints and surfaces we work on

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

Leave it or put it right?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. We cut out the old seal and prepare the faces every time. For buildings near Port Logan, dealing with all the failing joints at once saves return trips. Send photos and we’ll quote for everything together.

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

What you get with us

  • Work to your specification and the manufacturer’s guidance
  • Sealing commercial buildings since 2005
  • Our applicators hold CSCS cards
  • One phone line for London, the South East and Scotland

Quoting for work in Port Logan

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

  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses
  • How much existing material needs removing
  • Any access equipment needed

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

What to include in your enquiry

We can often quote from photographs and a few details. It helps to include:

  • Where the site is, with the postcode
  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email the details over.
