Common questions from Reay clients

Is a smaller place like Reay outside your area?

Not at all. Reay is within our area. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

Can one quote cover a number of our buildings near Reay?

Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.

How long does a typical visit take?

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

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will residents or tenants be disturbed?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.

Mastic sealing in Reay, done properly

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and what we’re called in for most is brittle perimeter mastic across a building and no planned programme for sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Reay, preparation and product choice get the time they need.

Outside mastic in Scotland needs dry joints and the right temperature, so work around Reay is planned with the forecast. We agree a window with some flexibility.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common problems we fix in Reay

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

What tends to prompt an enquiry:

  • Cracked, hardened mastic round windows on a block
  • Worn sealant at communal door frames
  • Draughts at frames across a block
  • Repeated reactive repairs to the same buildings

Owners near Reay can renew frame and external mastic block by block on one programme.

Before you book anyone

  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • How they’ll work around occupants
  • Proof of insurance

How to choose a sealant contractor

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Broken glass or failed sealed units
  • Substrate edges that need repairing first
  • Materials that need asbestos testing before work

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.

What we seal

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

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What the job involves on each surface

Tenement and older buildings

Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Block-wide mastic in Reay

With the shore within about 2 miles, Reay counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Being in the east of Scotland, Reay gets less rain than the west coast. Outside mastic still waits for dry, frost-clear conditions. Block programmes are built with that in mind

Churches, halls and community buildings such as Reay Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Reay is about 10 miles west of Thurso, in Highland. Across the KW14 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 256 places across Highland fall within our area, Reay among them.

Business premises anywhere in KW14 are within our area for mastic joints. For a building on The Terrace, The Avenue and Beinn Ratha Court or nearby, we can quote for mastic joints. Nearby places we also cover include Melvich (5 miles west), Portskerra (5 miles west), Forss (6 miles north-east), Westfield (6 miles east) and Janetstown (8 miles east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you give us a call on 01277 525 020 or use the quote form.

Nearby you will also find Dounreay Castle (2.1 miles north-east). The countryside around Reay includes Caol-Loch.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and we clear our waste as we work. Where we can, we combine work around Reay with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Before we start on site

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
