Facade sealing across Finstown

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

How we handle facade sealing in Finstown

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. Site teams most often ask us about cladding panel joints that have opened up and leaks at window and door perimeters, on window and door perimeters, cladding panel joints and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, in Finstown it comes down to the same thing: the right product in a properly prepared joint.

In smaller places such as Finstown, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints whose design needs changing by the specifier
  • Damaged frames that need replacing

Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.

What we seal

  • Coping and flashing joints
  • Window and door perimeters
  • Shopfront frames
  • Stone and brick facade joints
  • Cladding panel joints
  • Perimeter joints where frames meet the structure

Quoting for work in Finstown

We price every job individually. The main factors are:

  • Travel to remote or island sites
  • Which sealant the job calls for
  • The total length or number of joints
  • Whether old sealant has to be cut out first

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.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • The product your specification calls for
  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around

For a fixed quote, ring 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.

When to call us in Finstown

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Look out for the following:

  • Facade joints cracked through the middle
  • Previous reseals run over old sealant
  • Gaps between rainscreen or cladding panels
  • Perimeter joints where frames meet the structure

Sites around Finstown get mastic sealed to the drawings and the programme, nothing improvised.

What your quote should include

  • What site paperwork they can supply
  • Whether their applicators hold CSCS cards
  • Whether old or failed sealant will be cut out, not overlaid
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

How the job changes by surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs near Finstown are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached

Common questions from Finstown clients

Is hospital work, at somewhere like Balfour Hospital, something you do?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you take on a job in Finstown, on the island?

Yes. Every Scottish council area is within our area, and that includes island locations such as Finstown. We group island work where we can and plan around the crossings.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Can the building stay open while you work?

Typically, yes. Phased work can be planned so areas stay in use.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.

Facade sealing in Finstown: the local picture

Finstown is within about 1 mile of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Island jobs, Finstown among them, are planned around the ferry and the forecast. Drawings and the programme let us bring every sealant, primer and backing rod the package needs.

For a contractor working at a hospital such as Balfour Hospital, 5.7 miles east of Finstown, perimeter and facade sealing is planned around patients and deliveries.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Report water ingress at frames as soon as it shows
  • Add perimeter sealant to planned maintenance checks
  • Combine resealing with other works that need access
  • Insist on a full cut-out when joints are renewed

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down.
