Commercial sealant contractors for commercial buildings in Aird Tong

We’ve applied sealant on commercial sites for over 20 years: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. Site teams most often ask us about gaps behind commercial kitchen worktops and sinks and earlier reseals applied straight onto the failed bead, on floor and threshold joints, washrooms and tea points and window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, in Aird Tong it comes down to the same thing: the right product in a properly prepared joint.

In an occupied building in Aird Tong, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.

For work in and around Aird Tong, we’d rather do everything on one trip, so it helps to have photos and a full list first. If neighbouring businesses have work too, the visits can be grouped.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For work around Aird Tong, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Warn occupants and staff about the work
  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open

General trades versus a specialist

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

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Your questions answered

Can you supply sealant in our brand colour for a site in Aird Tong?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Do you work on the island where Aird Tong is?

Yes, Aird Tong is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

How many days will you need on site?

That varies with the scale of the job, but the work normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we’ll set out a timescale with the quote.

Does commercial sealant work come with a guarantee?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.

Are you CHAS accredited?

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

Different surfaces, different methods

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Commercial sealant contractors around Aird Tong: points for this area

The sea is no more than about 1 mile from Aird Tong. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. Being on an island, Aird Tong means planning around ferry times as well as the weather. Photos and a full list before we travel, with any colour references, mean everything comes on the first crossing.

Where a joint is on show in Aird Tong, we will check which shades the product offers before work starts. Whatever the building in Aird Tong, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

What sealant work can’t fix

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

  • Broken glass or blown double-glazed units
  • Structural cracks or movement the joints weren’t designed for
  • Suspect materials that need testing and specialist removal

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.

Surfaces we seal

  • Movement joints in walls and floors
  • External facade joints
  • Floor and threshold joints
  • Washrooms and tea points
  • Window and door perimeters
  • Kitchen worktops and splashbacks

What affects the price in Aird Tong

We price every job individually. The main factors are:

  • Location, for remote and island sites
  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition

We don’t publish prices, 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.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings

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, speak to us on 01277 525 020 or email drawings and photos.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep barriers up until the new sealant has cured
  • Put external and wet-area joints on a regular inspection round
  • Keep a record of which joints were resealed and when
  • Look at the sealant around anything that has been moved or replaced

Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early. If anything looks wrong, give us a call on 01277 525 020 or email us with a photo.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
