Questions we’re asked in Sgiogarstaigh

Does a coastal location like Sgiogarstaigh affect which sealant is used?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Is Sgiogarstaigh inside the area you cover, given it’s on an island?

Yes. Islands are part of our area, Sgiogarstaigh included. We group island work where we can and plan around the crossings.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you do fire-rated sealing on new builds?

It can be part of the package where specified. Record requirements are confirmed at quote stage.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

How we handle construction mastic in Sgiogarstaigh

Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items. We seal so the snag list stays short. We work on sanitary and kitchen joints, internal decorators’ caulk and cladding and panel joints, and what we are called in for most is inconsistent sealant finishes from plot to plot and bath and shower joints scraped during the final clean. One point of contact handles commercial sealant work in Sgiogarstaigh from the first photographs to the final walk-round, whether it’s one building or several.

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

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Sgiogarstaigh is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Damage to finishes by other trades after we’ve sealed
  • Approving fire stopping as compliant

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.

Surfaces we seal

  • Cladding and panel joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Window and door perimeters
  • Sanitary and kitchen joints
  • Internal decorators’ caulk

Building owners, agents and FMs in Sgiogarstaigh

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sgiogarstaigh can form part of a wider programme across Na h-Eileanan Siar.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Use the product the specification names
  • Keep scrapers and abrasive pads off new beads
  • Bring the mastic contractor in after the last trades are through
  • Ask for joint and product checks before the package is urgent

Any damage after we’ve finished should go on the snag list right away. We can return to clear snags before handover as agreed in the quote.

Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We flag them as soon as we see them.

Mastic packages on Sgiogarstaigh sites

Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind.

Sites around Sgiogarstaigh get mastic sealed to the drawings and the programme, nothing improvised. Around Sgiogarstaigh, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

What the job involves on each surface

Window and door perimeters

A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent.
