Expansion joint sealing in Ness

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. We work on podiums and floor movement joints, cladding panel joints and blockwork control joints, and what we are called in for most is brittle, chalky sealant on external joints and chipped joint edges on forklift routes. Facilities teams, main contractors and managing agents in Ness tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Weather windows decide external joint work around a place like Ness: dry faces and the right temperature are essential. Inside slabs aren’t affected and can be scheduled around the occupier.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Ness, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Let building users know which areas are affected
  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work

For managing agents and facilities managers

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

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

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Ness, a repair visit takes planning, so it’s better to act early.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why clients in Ness choose us

  • A range of standard colours, depending on the product
  • A fixed quote before work starts
  • RAL and finish matching where the product range allows
  • One phone line for London, the South East and Scotland

See our cost guide or how we’re accredited.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Damaged metal nosings or cover plates over a joint
  • Broken or spalled joint edges, which need repairing before any sealant goes in

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.

What we seal

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

Slabs, ramps and loading bays in Ness

The sea is no more than about 2 miles from Ness. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Island jobs, Ness among them, are planned around the ferry and the forecast. Joint widths, lengths and the traffic over them help us bring the right fillers and sealants.

In and around Ness, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Ness is about 18 miles north of Stornoway, in Na h-Eileanan Siar. We cover Ness and the rest of Na h-Eileanan Siar, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Na h-Eileanan Siar, 87 places are covered, including Ness.

If you need expansion joint sealing in HS2, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Sites close to Ness are covered too, including Nis (1 mile north), Cross (1 mile west), Sgiogarstaigh (1 mile east), Lionel (1 mile north) and North Dell (2 miles west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you call the office on 01277 525 020 or email a schedule or drawings.

Doing it in-house

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Signs you need expansion joint sealing in Ness

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

Things that normally lead to an enquiry:

  • Car park joints leaking onto vehicles below
  • Chipped joint edges on forklift routes
  • Sealant pulling off the joint face
  • Expansion joints split through the centre of the bead

Once a joint near Ness opens up, grit and water get in and the edges start to break.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?
  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Ness: questions and answers

Do you work on the island where Ness is?

Yes. Islands are part of our area, Ness included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Do we have to stop operations in Ness while the joints are sealed?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Are you insured?

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

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What sealant do you use in movement joints?

The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class.
