About our floor joint sealing in Firth

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we will tell you if the joint edges need repairing first and leave that decision with you. We work on loading bays, joints along racking aisles and construction joints, and what we are called in for most is filler that has parted from one face and saw-cut joints left open and packed with grit. A specialist sealant contractor works differently from a general builder: on jobs in Firth, preparation and product choice get the time they need.

Around smaller Scottish places like Firth, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

What sets the cost

We price every job individually. The things that drive the figure:

  • The total length or number of joints
  • Phasing around occupants
  • Travel to remote or island sites
  • The size and state of each joint

There’s no price list, since every building and every scope is different. Call for a quote.

Sending details for a quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around
  • What the building is and how it’s used

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

What happens if it’s left?

Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. None of it is designed for wheel loads and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Firth before they leak.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why clients in Firth choose us

  • Fully insured
  • Commercial sealant work since 2005

Questions we’re asked in Firth

Must our site in Firth stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Do you work on the island where Firth is?

Yes. Islands are part of our area, Firth included. We group island work where we can and plan around the crossings.

How do we get a quote for floor joints?

Use our quote form, or email photos and a plan and tell us what runs on the floor. We then send a fixed quote with the product and phasing set out.

Is it normal for joint filler to separate?

Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. A top-up normally puts it right.

Do you use semi-rigid filler or flexible sealant on floor joints?

The answer comes from the traffic and the joint’s movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do you have public liability insurance?

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

Joints that move: notes for Firth

Firth lies within about 2 miles of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. Firth is on Scotland’s drier eastern side. Freezing weather and salt still attack open external joints. Sealing them before winter limits the damage.

A joint near Firth that has lost its sealant lets in water and grit, and the edges suffer next.

Firth is in the Shetland Islands. We send applicators to Firth for floor joints, handled exactly as we handle every other area. We work across 63 places in the Shetland Islands, large and small.

Postcode districts covered here: ZE2. Streets here include Midlea, Leaside and Sandside, and sites on any of them can send details for a fixed quote. Just outside Firth, we also work in Mossbank (1 mile north-east), Scatsta (4 miles west), Vidlin (6 miles south), Sullom (6 miles west) and Burravoe (6 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Signs you need floor joint sealing in Firth

Left open, joints fill with grit, wrap and wood fragments. That debris is hard and levers at the edges as wheels pass, speeding up the damage.

Look out for the following:

  • A rough ride across broken joints
  • Loading bay joints breaking down
  • Sealant pulled out along a truck route
  • Grimy joint lines spoiling a showroom floor

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

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Will RAMS and insurance details be available?
  • Are they CHAS accredited or on Constructionline?
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Commercial clients in Firth

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Firth can sit alongside others in a wider programme.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building near Firth, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Getting the site ready

  • Confirm the product named in the specification
  • Arrange parking or a loading space
  • Share the asbestos register for older buildings

Keeping the joints sound

A few simple habits keep the new joints working:

  • Respect the cure time before traffic returns
  • Sweep debris out of open joints until they can be filled
  • Keep photos of joints that look like they’re failing
  • Treat loading bay joints first if they’re failing

Young concrete carries on shrinking, so some fillers part slightly from one face. That is common and is normally dealt with by topping up once the slab has settled down in most cases.

Grit in an open joint does damage every time a wheel crosses it. Filling it ends that cycle before it becomes a repair.
