After the work

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

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Keep a record of which joints were resealed and when
  • Deal with small splits before they become leaks
  • Ask fit-out and M&E contractors to report any sealant they disturb

Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, especially on exposed elevations and in washrooms. Should something look amiss, you can call the office on 01277 525 020 or send photos by email and send a picture.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

How we handle commercial sealant contractors in Corran

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. The enquiries we see most involve untidy joints in a reception, shop floor or lobby and shrunken sealant along kitchen worktops and splashbacks, across movement joints in walls and floors, floor and threshold joints and external facade joints. Most enquiries from Corran 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.

Quotes for commercial sealant in Corran can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.

For a job around Corran, the Scottish weather is part of the planning: outside joints need dry, frost-clear surfaces, so we agree a window with some give in it. Internal joints can be done whatever the day brings.

A 12-month guarantee applies to all our work in Highland. If an installation problem shows up, phone 01277 525 020 or use the quote form and we will arrange a return visit.

When to call us in Corran

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. Getting back to a clean joint then means removing every layer.

Typical triggers for a call:

  • Leaks that seem to come through a sealant line
  • Expansion joints with the sealant torn out
  • Earlier reseals applied straight onto the failed bead
  • Frame sealant that has cracked, shrunk or pulled away

A lasting commercial joint around Corran begins with the old bead fully out and the faces clean and dry.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • The terms of the workmanship guarantee
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Common questions from Corran clients

Does a coastal location like Corran affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. 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 Corran outside your area?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

How is commercial sealant work priced?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Can areas stay open during the work?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.

Can you take on work for an FM or managing agent?

Yes. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility, and we don’t remove asbestos-containing materials.

Why deal with it now?

Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Corran before they leak.

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.

Commercial sealant contractors around Corran: points for this area

Corran lies within about 1 mile of the sea. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. Being in the west of Scotland, Corran gets more rain than eastern areas. Frontage work is booked with a few days’ give for the weather.

For premises around Corran where the joint is seen, colour options for the product are confirmed with the quote.

Corran is in Highland. Across the PH33 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Corran is one of 256 places we cover in Highland for sealant joints. There’s a separate page for Glasgow, about 71 miles away.

Commercial sites across PH33 are covered for sealant joints. We also cover Clo Mhuillin (1 mile south-west), Inchree (1 mile east), Kentallen (3 miles south), Duror (5 miles south) and Ballachulish (5 miles south-east) for sealant joints.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

What affects the price in Corran

The price varies from site to site. Expect it to depend on:

  • Joint width, depth and condition
  • Removal of failed or old sealant
  • How much there is to seal
  • Whether the work must be split into stages

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Asbestos survey details if the building is older
  • Access details, including height
  • The site address and postcode
  • A wide shot and a close-up of the area

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email us to discuss it first.
