Facade sealing for Bun Othan sites

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

Quoting for work in Bun Othan

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Phasing around occupants
  • The total length or number of joints
  • Distance, for remote addresses
  • Any access equipment needed

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Photos of the joints, close up and from further back
  • Any dates the work must fit around
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email the details over.

Facade sealing in Bun Othan, done properly

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. If you have cladding panel joints that have opened up and facade joints cracked through the middle, we can help, on window and door perimeters, stone and brick facade joints and shopfront frames alike. A single leaking joint is often how a building in Bun Othan first comes to us: we look at the rest while we’re there and tell you what we find.

For a site around Bun Othan, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs near Bun Othan 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 start with photos, drawings or a visit to see the joints and agree 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.

What we need from you

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Confirm the product named in the specification

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Don’t wait for a second leak before calling
  • Ask about asbestos in pre-2000 mastic
  • Combine resealing with other works that need access
  • Keep pressure washers away from fresh sealant

Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Do you need facade sealing in Bun Othan?

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Typical triggers for a call:

  • Cold air coming in at window perimeters
  • Gaps between rainscreen or cladding panels
  • New sealant peeling off old mastic
  • Hard, chalky sealant that no longer flexes

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

FAQs: Bun Othan

Is Bun Othan too far out for you?

No. Small places get the same service as large ones. We work across every Scottish council area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work to our programme on a site in or near Bun Othan?

Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

What do you charge?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Do you hold CHAS accreditation?

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

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Facade sealing around Bun Othan: points for this area

Bun Othan is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Bun Othan is in the west of Scotland, the wetter side of the country. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days.

Around Bun Othan, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

Owners, agents and contractors

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.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
