About our facade sealing in Hamnavoe

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about previous reseals run over old sealant and cladding panel joints that have opened up, across cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in Hamnavoe tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In smaller places such as Hamnavoe, 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.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Cost factors for facade joints

The price varies from site to site. It mainly depends on:

  • How accessible the joints are
  • The size and state of each joint
  • Distance, for remote addresses
  • Whether old sealant has to be cut out first

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.

Maintenance after handover

Cleaning and maintenance staff play a part too. Share these points with them:

  • Avoid patch repairs on failed facade joints
  • Avoid harsh cleaners on facade sealant
  • Ask about asbestos in pre-2000 mastic
  • Keep sills, gutters and drainage paths clear

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.

For managing agents and facilities managers

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.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Facades, frames and programmes in Hamnavoe

The sea is no more than about 1 mile from Hamnavoe. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. For an island location such as Hamnavoe, work is planned around ferry crossings and the weather. Everything for the package travels with us, so drawings and quantities matter.

A facade joint near Hamnavoe lasts when width, depth and backing are right, not just the finish.

Hamnavoe is in the Shetland Islands. Anywhere in ZE2, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Hamnavoe is one of 63 places we cover in the Shetland Islands.

Commercial sites across ZE2 are covered for facade joints. If your site is on Glenburn Road, Atlaness and Gudda Taing or close by, send details and we will quote for facade joints. If your building is just outside Hamnavoe, we cover Toogs (1 mile south), Scalloway (3 miles north-east), Gulberwick (5 miles east), Cunningsburgh (5 miles south-east) and Bremirehoull (6 miles south-east). A short drive away, we cover Lerwick (7 miles north-east), Sound (6 miles north-east) and Sandwick (8 miles south-east). Among the larger centres in the Shetland Islands is Hamnavoe, and its commercial and public buildings are all within our area. Where a site is remote or on an island, we plan travel and materials carefully.

A little further out are Scalloway Museum (3.5 miles north-east). Not far away are West Loch and Hill of Berry.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Where we can, we combine work around Hamnavoe with other jobs nearby. Let us know if your dates have any give.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Make sure the joints can be reached
  • Point out any areas we must not close
  • Share the asbestos register for older buildings

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we’re called out for in Hamnavoe

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

It’s worth sending us details if you spot any of the following:

  • Weathered facade joints that have lost their grip
  • Damp patches beside frames after rain
  • Cold air coming in at window perimeters
  • Failed seals around shopfront and entrance frames

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

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Your questions answered

Can the mastic package for our job in Hamnavoe follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

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

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can call 01277 525 020 or email us to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can the building stay open while you work?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
