Commercial mastic work in Sandwick
If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Sandwick, phone 01277 525 020 or use the quote form with the site addresses. We work on external facade joints, window and door perimeters and floor and threshold joints, and what we are called in for most is messy, uneven beads from earlier work that let the building down and weathered facade sealant that no longer flexes. Whether you call it commercial sealant work, mastic application or joint sealing, in Sandwick it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
We price commercial jobs in Sandwick from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.
Travel to smaller places such as Sandwick is planned so the whole job is finished in one visit where possible: send photos and a complete list so the right products and colours come on the day. If neighbouring businesses have work too, the visits can be grouped.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we will arrange a return visit.

Aftercare for building managers
Once the work is signed off, these steps help:
- Have extract fans checked so wet areas dry out
- Ask fit-out and M&E contractors to report any sealant they disturb
- On pre-2000 buildings, share the asbestos information before work starts
- Brief cleaning contractors to avoid scourers and blades on sealant
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.
Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Roof leaks that only look like a joint problem
- Broken glass or blown double-glazed units
- Cracking that needs a structural engineer to look at it
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think.
Surfaces we seal
- External facade joints
- Floor and threshold joints
- Movement joints in walls and floors
- Window and door perimeters
- Washrooms and tea points
- Kitchen worktops and splashbacks
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Sandwick. That goes into the plan alongside the quote.
- First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Getting the site ready
- Tell staff and tenants when we will be in
- Agree which areas must stay open
- Arrange parking or a loading space

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Your questions answered
Can you take on a job in Sandwick, on the island?
Yes. Islands are part of our area, Sandwick included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Can you supply sealant in our brand colour for a site 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. Available colours for the product are confirmed with the quote.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Will the building have to shut during the work?
We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you work directly for building managers?
Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.
Why deal with it now?
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, so access and set-up end up being paid for twice. We can price both options so you can decide on the facts. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Sandwick, a repair visit takes planning, so it’s better to act early.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Working on commercial sites near Sandwick
Sandwick is within about 1 mile of the coast. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. We choose a product rated for the exposure, then confirm the colours available for it. The east of Scotland, where Sandwick is, gets less rain than the west. 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.

When to call us in Sandwick
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
Things that typically lead to an enquiry:
- Hardened, chalky sealant on south-facing or exposed elevations
- Wall and floor joints that have lost their seal
- Greasy, split joints in a kitchen or tea point
- Sanitary sealant that has gone black and patchy
For premises around Sandwick where the joint is seen, colour options for the product are confirmed with the quote.
