Commercial sealant contractors in Tankerness

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

Sealant applicators in Tankerness

We have applied sealant on commercial sites for over 20 years: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. If you are dealing with water staining near frames, panels or ceilings and gaps behind commercial kitchen worktops and sinks, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Tankerness from the first photos to the final walk-round, whether it’s one building or several.

If you look after more than one building near Tankerness, the work can be planned as one programme, so standards and paperwork match across every site.

For a job around Tankerness, the Scottish weather is part of the planning: sealant needs a dry joint and the right temperature, so external work has a weather window built in. Indoor work isn’t held up by rain.

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’re clear about what is covered before work starts.

Frontages, fit-outs and joints in Tankerness

With the shore within about 1 mile, Tankerness counts as a coastal location. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. A matched colour is only half the brief on an exposed frontage. The east of Scotland, where Tankerness is, gets less rain than the west. Frost and condensation on winter mornings can still hold up external sealing. In winter, outside joints are timed for when surfaces are dry and within the product’s range

For premises around Tankerness where the joint is seen, colour options for the product are confirmed with the quote. Whatever the building in Tankerness, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Tankerness is about 4 miles east of Kirkwall, in the Orkney Islands. Our applicators travel to Tankerness for work on sealant joints, handled exactly as we handle every other area. Across the Orkney Islands, 51 places are covered, including Tankerness.

Surface by surface

Washrooms and toilets

Mould that has grown into washroom sealant can’t typically be cleaned out. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.

Fire-rated seals where specified

Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, so we’ll flag it if the detail needs a different product.

Commercial clients in Tankerness

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Tankerness can form part of a wider programme.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Tankerness, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Before we start on site

Leave it or put it right?

On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. You notice the difference years later, not on the day. Around smaller places like Tankerness, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Common questions from Tankerness clients

Will you travel to Tankerness on the island?

Yes, Tankerness 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.

Can the sealant on our Tankerness premises match the finishes?

Yes, we can usually get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

How do you keep disruption to occupiers down?

Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we are sealing, until its cure time has passed.

What do you need from us to quote?

Send photographs, drawings or a list of locations. If a visit is needed we will book one, and a fixed quote follows.

How soon can the area be used again?

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.

Could the old sealant in an older building contain asbestos?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • A failed roof covering or waterproofing membrane
  • Old mastic that tests positive for asbestos
  • Leaks from pipework, wastes or valves (that’s plumbing)

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
