Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Suspect materials that need testing and specialist removal
  • Structural cracks or movement the joints weren’t designed for
  • Roof leaks that only look like a joint problem

If in doubt, phone 01277 525 020 or email us and we’ll say what we think before you book.

Where we work in Colbost

  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • External facade joints
  • Washrooms and tea points
  • Window and door perimeters

Sealant specialists in Colbost

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested. If you are dealing with hardened, chalky sealant on south-facing or exposed elevations and sanitary sealant that has gone black and patchy, we can help, whatever the surface. For commercial sealant work in Colbost, you deal with one contact from quote to sign-off, whether it’s one building or several.

On a typical commercial building in Colbost, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

For a job around Colbost, the Scottish weather is part of the planning: sealant needs a dry joint and the right temperature, so external work has a weather window built in. Indoor work isn’t held up by rain.

We sign every job 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.

Common problems we fix in Colbost

External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain. A hardened bead can’t follow the building any more.

Things that usually lead to an enquiry:

  • Hardened, chalky sealant on south-facing or exposed elevations
  • A top-up bead over failed sealant, now lifting
  • Damp patches where an external joint has failed
  • Frame mastic that has hardened and come away from the wall

Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • How the joint faces will be prepared and primed
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes part of a day on a small job and longer where several buildings or phases are involved, and our waste is bagged and taken away as we go. Tell us who will meet us and how to get in at your building near Colbost. That goes into the plan alongside the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Warn occupants and staff about the work

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • The site’s rules and procedures
  • Removal of failed or old sealant
  • The size and state of each joint
  • How much there is to seal

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The site address and postcode
  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email drawings and photos.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Some joints are best left to specialists: for example 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.

FAQs: Colbost

Is Colbost off your patch?

Not at all. Colbost is within our area. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.

Our building in Colbost is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Is it OK to apply fresh sealant over existing beads?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts.

Which site documents can you send us?

The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.

Looking after the joints

Once the work is signed off, these steps help:

  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Keep washroom and kitchen extraction working
  • Check sealant as part of routine building inspections
  • Make sure contractors see the asbestos survey before cutting out old mastic

Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. Should something look amiss, you can phone 01277 525 020 or use the quote form and send a picture.

Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Planned replacement saves fielding the same complaint again and again.

Frontages, fit-outs and joints in Colbost

With the shore within about 1 mile, Colbost counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. We choose a product rated for the exposure, then confirm the colours available for it. The west of Scotland, where Colbost is, gets more rain than the east. Frontage work is booked with a few days’ give for the weather. Weather-facing frames tend to need resealing before the sheltered ones

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