Facade sealing across West Side

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Leave it or put it right?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, often turning up far from the joint. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around West Side before they leak.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

About our facade sealing in West Side

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you are dealing with air leaks through failed facade joints and hard, chalky sealant that no longer flexes, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in West Side is the same: the right product in a properly prepared joint.

For a site around West Side, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.

Every job is signed 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.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Joints whose design needs changing by the specifier
  • Work on the window or framing system itself
  • Damaged frames that need replacing

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

Joints and surfaces we work on

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

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For work around West Side, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  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. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Make sure the joints can be reached
  • Let building users know which areas are affected

Facade sealing around West Side: what changes locally

The sea is no more than about 2 miles from West Side. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Being in the west of Scotland, West Side gets more rain than eastern areas. External mastic needs dry spells, with internal work ready to fill the wet days.

New units and refits on sites such as Barvas Industrial Estate, less than half a mile to the south-east of West Side, need their panel and perimeter joints sealed to the specification.

West Side is about 11 miles north-west of Stornoway, in Na h-Eileanan Siar. Looking for facade sealing in West Side? We can help. West Side is one of 87 places in Na h-Eileanan Siar on our list for facade joints.

Anyone looking for facade sealing in HS2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Among the streets we cover are Gleann Mor, Heatherhill and Sraid na Loch, and sites on any of them can send details for a fixed quote. Just outside West Side, we also work in Barabhas (1 mile north-west), Bragar (4 miles west), Shader (4 miles north-east), Borgh (6 miles north-east) and Shawbost (7 miles west). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Common questions from West Side clients

Do you cover business parks and estates near West Side, such as Barvas Industrial Estate?

Yes. Our area takes in West Side and its surroundings, with estates and business parks such as Barvas Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Does a coastal location like West Side affect which sealant is used?

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.

Are you CHAS accredited?

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

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you seal facades in winter?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated as the work goes on.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What affects the price in West Side

Your fixed quote is built from the real scope. It takes account of:

  • Site requirements such as inductions and permits
  • The total length or number of joints
  • Distance, for remote addresses
  • Whether old sealant has to be cut out first

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • When you need the work done
  • Whether the building will be occupied during the work

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or send details through our quote form with what you know.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in West Side can sit alongside others in a wider programme across Na h-Eileanan Siar.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

What we are called out for in West Side

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

What tends to prompt an enquiry:

  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints
  • Discoloured or dirty facade joints
  • Previous reseals run over old sealant

On any site in or around West Side, the mastic follows the specification and the programme.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • Whether old or failed sealant will be cut out, not overlaid
  • Can the work be phased to keep areas open?
