How we handle mastic sealing in Tenston

For blocks and buildings in Tenston and across the Orkney Islands, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells, and what we’re called in for most is no planned programme for sealant and estate-wide sealant that is simply worn out. A single leaking joint is often how a building in Tenston first comes to us: we look at the rest while we’re there and tell you what we find.

Around Tenston, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about Tenston

Do you work on the island where Tenston is?

Yes. We work across every Scottish council area, and that includes island locations such as Tenston. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Can being near the sea in Tenston affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

What happens if it’s left?

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Tenston, a repair visit takes planning, so it’s better to act early.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

What you get with us

  • Standard and matched colours in many product ranges
  • One contact handling all your sites
  • Colour options checked against the specified product
  • Old sealant cut out, never sealed over

Mastic sealing in Tenston: the local picture

The sea is no more than about 1 mile from Tenston. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Being in the east of Scotland, Tenston gets less rain than the west coast. Frost and condensation on winter mornings can still delay outside mastic. We plan block programmes with some give for it

Student accommodation around universities such as Heriot-Watt University - Orkney Campus, 4.9 miles south of Tenston, is usually managed block by block, which suits a planned mastic programme.

Tenston is about 12 miles west of Kirkwall, in the Orkney Islands. We send applicators to Tenston for mastic joints, handled exactly as we handle every other area. Our the Orkney Islands coverage takes in 51 places, from busy centres to rural villages.

Postcode districts covered here: KW16. We also cover Wasbister (1 mile south), Russland (2 miles north-east), Hourston (2 miles north-east), Skeabrae (3 miles north) and Harray (3 miles east) for mastic joints. Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you call 01277 525 020 or email drawings and photos.

Local landmarks in Tenston

Well-known places in the area include Skara Brae Visitor Centre (2.8 miles north-west). Green spaces nearby include Mill Dam of Rango and Hill of Miffia.

Common problems we fix in Tenston

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.

If one of these sounds familiar, it’s time for a closer look:

  • Movement joints with sealant missing
  • Draughts at frames across a block
  • A mix of products and colours from past repairs
  • Window mastic that has split and shrunk

With historic buildings such as Skaill House (to the north-west of Tenston) in the wider area, owners of older properties around Tenston should expect mastic to need a product that suits old masonry.

What your quote should include

  • How they handle RAMS and site documents
  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Plan resealing building by building rather than complaint by complaint
  • Look at the sunniest and most exposed elevations first
  • Check sealant joints during planned building inspections
  • Share your contractor requirements early

Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Where we can, we combine work around Tenston with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

What we need from you

  • Send your site hours and access windows
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
