Facade sealing in Houbie

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. Site teams most often ask us about discoloured or dirty facade joints and perimeter sealant that has split or peeled away, across shopfront frames, coping and flashing joints and stone and brick facade joints. Most enquiries from Houbie start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Houbie that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Houbie, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Flag any permit to work we will need

Advice

What we are called out for in Houbie

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

Things that usually lead to an enquiry:

  • Weathered facade joints that have lost their grip
  • Cladding panel joints that have opened up
  • Failed seals around shopfront and entrance frames
  • Draughts around frames and panels

When a school such as Fetlar Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Before you book anyone

  • Proof of insurance
  • Will failed sealant be removed rather than covered?
  • Which product they’ll use, and why it suits the joint
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Common questions from Houbie clients

Will you fit the mastic around our build programme in Houbie?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you work on the island where Houbie is?

Yes. Islands are part of our area, Houbie included. Ferry times and the weather set the plan, so we ask for photos and a full list first.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Surface by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

What we can’t put right

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
  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.

Where we work in Houbie

Quoting for work in Houbie

Quotes vary with the job. It mainly depends on:

  • The total length or number of joints
  • Distance, for remote addresses
  • How accessible the joints are
  • Removal of failed or old sealant

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • Your programme or deadline

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or send details through our quote form.

Contractors’ notes for Houbie

With the shore within about 1 mile, Houbie 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. Island jobs, Houbie 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.

Historic houses such as Brough Lodge (to the west of Houbie) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
