Common problems we fix in Sgiogarstaigh

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.

Look out for the following:

  • Water getting in round frames after rain
  • No planned programme for sealant
  • Estate-wide sealant that is simply worn out
  • Cracked, hardened mastic round windows on a block

Near Sgiogarstaigh, we review each elevation first so the quote covers what actually needs doing.

Choosing a commercial sealant contractor

Mastic sealing for commercial buildings in Sgiogarstaigh

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. The enquiries we see most involve repeated reactive repairs to the same buildings and communal area joints that look neglected, across external wall and movement joints, shopfronts below residential blocks and communal entrances and stairwells. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sgiogarstaigh it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Travel to smaller places like Sgiogarstaigh is planned so several buildings can be done on one trip. A list of addresses and photos lets us quote for them together.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Tell us who will meet us and how to get in at your building near Sgiogarstaigh. That goes into the plan alongside the quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Move anything stored against the joints
  • Send your site hours and access windows

How the job changes by surface

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

FAQs: Sgiogarstaigh

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

Yes, Sgiogarstaigh is within the area we cover. We work across every Scottish council area. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Do you take on block-wide or estate-wide mastic work in Sgiogarstaigh?

Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Asbestos-containing sealant, which we don’t remove
  • Masonry that has broken away beside the joint
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Surfaces we seal

  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • External wall and movement joints
  • Communal kitchens and washrooms
