Facade sealing for commercial buildings in Tom nan Ragh

External joints face UV, rain, temperature swings and building movement all year. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on perimeter joints where frames meet the structure, shopfront frames and stone and brick facade joints, and the usual reasons a site gets in touch are weathered joints at frame-to-structure perimeters and damp patches beside frames after rain. Facilities teams, main contractors and managing agents in Tom nan Ragh tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction around smaller Scottish places like Tom nan Ragh is often one-off schemes: a school, a health centre, a hotel extension or a few houses. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites around Tom nan Ragh. Several sites can go on one quote, which keeps the paperwork simple.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Common problems we fix in Tom nan Ragh

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.

Site and facilities staff are often the first to spot these:

  • Unsightly perimeter sealant on a visible elevation
  • Sealant pulling away from frames or panels
  • Gaps between rainscreen or cladding panels
  • New sealant peeling off old mastic

Work at a hotel such as Cot House Hotel (0.8 miles north of Tom nan Ragh) tends to be programmed around bookings, mastic included.

Our contractor checklist

After the work

For the best life from the joints:

  • Walk the elevations once or twice a year
  • Never let anyone seal over old sealant
  • Brief window cleaners about newly sealed joints
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.

Quoting for work in Tom nan Ragh

What shapes the price:

  • Access and working height
  • How much existing material needs removing
  • The total length or number of joints
  • Which sealant the job calls for

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used
  • The site address and postcode
  • Any dates the work must fit around

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email us.

Different surfaces, different methods

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.

Common questions from Tom nan Ragh clients

Is Tom nan Ragh too small for you to travel to?

No. Places such as Tom nan Ragh are covered as much as the big towns. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Cowal Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Are you fully insured?

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

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Can you work in cold or wet weather?

Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Where we can, we combine work around Tom nan Ragh with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Point out parking and an unloading spot
  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000

Contractors’ notes for Tom nan Ragh

With the shore within about 1 mile, Tom nan Ragh counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. The west of Scotland, where Tom nan Ragh is, gets more rain than the east. External mastic needs dry spells, with internal work ready to fill the wet days.

Hospital estates such as Cowal Community Hospital, 2.8 miles south-east of Tom nan Ragh, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Tom nan Ragh is about 8 miles north-west of Greenock, in Argyll and Bute. Commercial clients in Tom nan Ragh use us for work on facade joints. We work across 124 places in Argyll and Bute. We also cover Glasgow, some 29 miles away.
