Expansion joint sealing for commercial buildings in Hamnavoe

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. The enquiries we see most involve debris jammed in movement joints and movement joints with split or torn sealant, on podiums and floor movement joints, car park decks and ramps and cladding panel joints. Looking for mastic applicators who cover Hamnavoe? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

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

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Changing the joint layout or spacing of a structure
  • Crumbling edges that would give a new bead nothing sound to grip
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If you are not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer.

Joints and surfaces we work on

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

Different surfaces, different methods

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

After the work

To get the most from the new sealant:

  • Act on the first tear or lifting edge rather than waiting
  • Avoid parking heavy plant or pallets on joint lines
  • Record the sealant used and the date in the O&M file
  • Inspect movement joints alongside other routine building checks

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Catching it early keeps the water outside.

Slabs, ramps and loading bays in Hamnavoe

The sea is no more than about 1 mile from Hamnavoe. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Being in the east of Scotland, Hamnavoe gets less rain than the west coast. Cold winters and gritting are hard on any yard or deck joint left open. Sealing them in drier months limits winter damage.

For floors and slabs around Hamnavoe, the product is chosen for the traffic and the movement at each joint. Around Hamnavoe, open joints collect water and debris, and the arrises are the next to go; we will tell you if the edges need repairing first.

Hamnavoe is in the Shetland Islands. Across the ZE2 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Hamnavoe is one of 63 places in the Shetland Islands on our list.

Quoting for work in Hamnavoe

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • How accessible the joints are
  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Working within restricted access windows

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • Any dates the work must fit around

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or use the quote form.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Hamnavoe is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Let building users know which areas are affected
  • Let us know about inductions and permits

FAQs: Hamnavoe

Do you work on the island where Hamnavoe is?

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

Does a site in Hamnavoe have to shut while its joints are sealed?

Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
