Expansion joint sealing across Stornoway

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

Floors, slabs and movement joints in Stornoway

Stornoway 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, so a failed joint lets more in and the edges break up sooner. Being on an island, Stornoway means planning around ferry times as well as the weather. Joint widths, lengths and the traffic over them help us bring the right fillers and sealants.

Large sites such as Western Isles Hospital, 0.5 miles north of Stornoway, have car parks, service roads and long elevations with movement joints in brick and panels. Across sites such as Marybank Industrial Estate (1 mile west of Stornoway), floor and movement joints can be sealed in phases so units keep working. For buildings at a park such as Gleann Seileach Business Park, 0.8 miles to the north-west of Stornoway, brick and panel movement joints are easy to forget until one leaks.

Stornoway (Gaelic: Steòrnabhagh) is in Na h-Eileanan Siar. Commercial clients in Stornoway can call on us for movement joints, as part of our coverage of Na h-Eileanan Siar. We work across 87 places in Na h-Eileanan Siar, large and small.

We take on movement joints across the HS1 and HS2 postcode area. For a building on Barony Square, Bain Square and Grant Square or nearby, we can quote for movement joints.

Stornoway ranks among the main centres of Na h-Eileanan Siar, with offices, shops, schools and other public and commercial buildings, and we cover them all.

About our expansion joint sealing in Stornoway

If you need expansion joint sealing in Stornoway, start with photos and joint lengths. Send them through our quote form, and we will arrange a site visit if needed, then send a fixed quote that names the sealant. You can also phone 01277 525 020 or send details through our quote form to talk the joints through. We work on cladding panel joints, precast concrete panel joints and brickwork movement joints, and the failures we’re asked to look at most are sealant pulling off the joint face and joints packed with grit and debris. Searching for sealant specialists in Stornoway? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

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

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

After the work

To get the most from the new sealant:

  • Plan racking layouts so feet don’t land on a joint
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep traffic off new joints until the cure time is up
  • Brief car park operatives to protect joint lines during winter clearance

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Resealing promptly prevents internal damage.

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Travel to smaller Scottish places like Stornoway is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  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. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached
  • For older buildings, check the asbestos register before work

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Related advice

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Cost factors for movement joints

Your fixed quote is built from the real scope. It takes account of:

  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • The asbestos register, for older buildings
  • Access details, including height
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them

To get a fixed quote, call the office on 01277 525 020 or email us with the site address and an outline of the work. Our quote form is another easy route.

Stornoway: questions and answers

Can you take on a job at a hospital such as Western Isles Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Our building in Stornoway is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement, and phased work can be planned so parts of the car park stay in use.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Different surfaces, different methods

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photos help us judge the joints or a site visit fills the gaps.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

Leave it or put it right?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. Renewing every failing joint on one visit is the sensible approach for a place like Stornoway. Send photos and we’ll quote for everything together.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
