Expansion joint sealing for businesses in Keiss

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

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Where we can, we combine work around Keiss with other jobs nearby. Let us know if your dates have any give.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  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. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  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.

Advice

Expansion joint sealing in Keiss, done properly

A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve weathered movement joint sealant that no longer flexes and joints where the bead has lost adhesion, on cladding panel joints, brickwork movement joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Keiss is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Expansion joint sealing in Keiss: the local picture

With the shore within about 1 mile, Keiss counts as a coastal location. 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, Keiss gets less rain than the west coast. Freezing weather and salt still attack open external joints. Autumn is a sensible time to seal them.

Around Keiss, open joints collect water and debris, and the arrises are the next to go.

Keiss is about 15 miles east of Thurso, in Highland. Commercial clients in Keiss use us for work on movement joints, as part of our coverage of Highland. Keiss is one of 256 places in Highland on our list for movement joints.

Business premises anywhere in KW1 are within our area. If your site is on High Street, South Street and Robertson Crescent or close by, send details and we will quote for movement joints. Just outside Keiss, we also work in Reiss (4 miles south), Ackergillshore (4 miles south), Hastigrow (5 miles west), Staxigoe (6 miles south-east) and Haster (6 miles south). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Maintenance after handover

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

  • Treat a small split as a warning, not a cosmetic issue
  • Brief car park operatives to protect joint lines during winter clearance
  • Keep traffic off new joints until the cure time is up
  • Include every elevation and deck joint in periodic inspections

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can call the office on 01277 525 020 or send details through our quote form and send a picture.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

What the job involves on each surface

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Why it’s worth doing now in Keiss

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Keiss, a repair visit takes planning, so it’s better to act early.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Keiss choose us

  • Our applicators hold CSCS cards
  • CHAS accredited contractor
  • Work to your specification and the manufacturer’s guidance
  • A Constructionline member, so easy to vet

Do you need expansion joint sealing in Keiss?

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. The product has to be suited to the traffic.

Typical triggers for a call:

  • Previous reseals laid over old sealant
  • Water dripping through deck or ramp joints
  • Expansion joints split through the centre of the bead
  • Chipped joint edges on forklift routes

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

Common questions from Keiss clients

Can being near the sea in Keiss affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is a smaller place like Keiss outside your area?

No. Places such as Keiss are covered as much as the big towns. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you reseal car park expansion joints?

Yes. We use a sealant designed for wheel loads and the expected movement.

What exactly is a movement joint?

They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.

Why do our movement joints keep failing?

Usually the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
