Expansion joint sealing near Gremista

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How we handle expansion joint sealing in Gremista

For movement joints in Gremista, photos and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed. To discuss the joints first, call 01277 525 020 or use the quote form. Site teams most often ask us about expansion joints split through the centre of the bead and sealant pulling off the joint face, on precast concrete panel joints, brickwork movement joints and podiums and floor movement joints. Most enquiries from Gremista start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For outside joints near Gremista, the Scottish weather sets the timetable: 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.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Tell us who will meet us and how to get in at your building near Gremista. That goes into the plan alongside the quote.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Agree which areas must stay open
  • Arrange parking or a loading space

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Reopen bays and walkways only after the stated cure time
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Inspect movement joints alongside other routine building checks
  • Keep scrapers and ploughs from dragging across joint sealant

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

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. Catching it early keeps the water outside.

Quoting for work in Gremista

Quotes vary with the job. It mainly depends on:

  • Specialist products, such as fire-rated or hygienic sealants
  • Working within restricted access windows
  • Travel to remote or island sites
  • Joint width, depth and condition

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

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

  • The postcode of the building
  • Your programme or deadline
  • How the joints are reached, and at what height
  • The product your specification calls for

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, phone 01277 525 020 or email a schedule or drawings.

Why it’s worth doing now in Gremista

On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. Renewing every failing joint on one visit is the sensible approach for a place like Gremista. Send photographs and we’ll quote for everything together.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What we are called out for in Gremista

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.

Look out for the following:

  • Joints packed with grit and debris
  • Weathered movement joint sealant that no longer flexes
  • Water getting into the wall through a failed joint
  • Spalled or broken joint edges in floors and decks

Another example is Black Hill Industrial Estate, under half a mile to the west of Gremista, where floors and yards would be done in stages around the occupiers.

How to choose a sealant contractor

How the job changes by surface

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.

Warehouse floors and decks around Gremista

With the shore within about 1 mile, Gremista counts as a coastal location. 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. Gremista is in the east of Scotland, which is drier than the west. Cold winters and gritting are hard on any yard or deck joint left open. Sealing them in drier months limits winter damage.

For a school such as Anderson High School, playground and building joints can be done in the holidays. Estates like Lower Black Hill Industrial Estate (to the south-west of Gremista) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Gremista is about 1 mile north of Lerwick, in the Shetland Islands. We cover commercial sites throughout Gremista, for single jobs and planned programmes alike. 63 places across the Shetland Islands fall within our area, including Gremista.

Business premises anywhere in ZE1 are within our area. For a building on Gremista Road, Arlanda Yard and Holmsgarth Brae or nearby, send details and we will quote for movement joints. Just outside Gremista, we also work in Heogan (1 mile east), Lerwick (1 mile south), Sound (2 miles south), Gunnista (2 miles east) and Veensgarth (2 miles west). For island and remote sites, travel and materials need planning ahead.

Your questions answered

Do you cover business parks and estates near Gremista, such as Lower Black Hill Industrial Estate?

Yes. Our area takes in Gremista and its surroundings, with estates and business parks such as Lower Black Hill Industrial Estate included. A few photographs and the unit address let us price the work.

Do you work on the island where Gremista is?

Yes. Islands are part of our area, Gremista included. Ferry times and the weather set the plan, so we ask for photographs and a full list first.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

Do you use silicone or polyurethane in movement joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks typically need a polyurethane.

Are you CHAS accredited?

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