Sealant on show in Sandwick’s commercial buildings
Sandwick is within about 1 mile of the coast. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. Sandwick is on Scotland’s drier eastern side. Winter frost and damp frames still stop outside sealing on some days.
For any commercial premises in Sandwick, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Sealant specialists in Sandwick
Sealant joints are easy to overlook until one lets water in, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Sandwick. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you are dealing with smeared sealant across finishes from a rushed job and mouldy silicone around WCs, urinals and vanity tops, we can put it right, on window and door perimeters, washrooms and tea points and floor and threshold joints alike. A specialist sealant contractor works differently from a general builder: in Sandwick, that means joint design, primers and backing rod as standard.
In an occupied building in Sandwick, 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 Sandwick, we’d rather do everything on one trip: send photos and a complete list so the right products and colours come on the day. Several jobs nearby can also be put together.
A 12-month guarantee applies to all our work in the Shetland Islands. Should something we installed fail, phone 01277 525 020 or email the details over and we’ll come back to it.

Signs you need commercial sealant contractors in Sandwick
In wet areas the enemy is usually mould rather than movement. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead; when mould is in the body of the sealant, no cleaner will shift it. Replacement with a sanitary anti-mould silicone is the lasting answer.
These are often picked up first by site or facilities staff:
- Frame mastic that has hardened and come away from the wall
- Gaps behind commercial kitchen worktops and sinks
- Movement joints packed with grit and debris
- Smeared sealant across finishes from a rushed job
For premises around Sandwick where the joint is seen, colour options for the product are confirmed with the quote.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Who will actually carry out the work
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Misted, cracked or failed glazing units (a glazier’s job)
- Old mastic that tests positive for asbestos
- Leaks from pipework, wastes or valves (that’s plumbing)
Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Movement joints in walls and floors
- External facade joints
- Kitchen worktops and splashbacks
- Window and door perimeters
- Washrooms and tea points
- Floor and threshold joints
Keeping the joints sound
To get the most from the new sealant:
- Don’t let cleaning or traffic back on before the cure time is up
- On pre-2000 buildings, share the asbestos information before work starts
- Keep a record of which joints were resealed and when
- Look at the sealant around anything that has been moved or replaced
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.
Common questions from Sandwick clients
Can you match sealant colours for premises in Sandwick?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
Our building in Sandwick is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How many days will you need on site?
It depends on the scope, 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.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can weather delay the job?
It can, for external work. 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.
Is your work guaranteed?
It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.
Why deal with it now?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We’ll suggest an order, worst sealant joints first. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Sandwick before they leak.
Pricing sealant joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

How a job runs

For work around Sandwick, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
- We work out why the joints have failed and fix a quote for the agreed scope.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.

Advice
What sets the cost
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- How much there is to seal
- Location, for remote and island sites
- The size and state of each joint
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- The type of building and who uses it
- Drawings or a marked-up plan, if available
- A wide shot and a close-up of the area
- Where the site is, with the postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
