Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Haroldswick, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- We start with the evidence: photographs, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Send your site hours and access windows
- Arrange parking or a loading space
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

About our commercial sealant contractors in Haroldswick
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). Site teams most often ask us about frame mastic that has hardened and come away from the wall and shrunken sealant along kitchen worktops and splashbacks, on external facade joints, movement joints in walls and floors and washrooms and tea points. Looking for mastic applicators who cover Haroldswick? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Occupied buildings in Haroldswick need the work phased: we agree the order with you and hand back each area with its cure time.
For work in and around Haroldswick, 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Roof leaks that only look like a joint problem
- Leaks from pipework, wastes or valves (that’s plumbing)
- Cracking that needs a structural engineer to look at it
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

What affects the price in Haroldswick
Each job is priced on its own details. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- How accessible the joints are
- Location, for remote and island sites
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
What we need to price the job
A few photographs plus some basic facts will normally do. It helps to include:
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- Whether an asbestos survey exists
Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or email us.
What else we do in Haroldswick
Sealant on show in Haroldswick’s commercial buildings
The sea is no more than about 2 miles from Haroldswick. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Where a frontage needs a particular colour, the product still has to suit that exposure. Being on an island, Haroldswick means planning around ferry times as well as the weather. Photos and a full list before we travel, with any colour references, mean everything comes on the first crossing.
Where a joint is on show in Haroldswick, we will check which shades the product offers before work starts.
Haroldswick is in the Shetland Islands. If you are looking for commercial sealant contractors in Haroldswick, we can help. We work across 63 places in the Shetland Islands, large and small.
Commercial sites across ZE2 are covered for sealant joints. Buildings on Taftens, Nordabrake and Brakefield Crescent are within our area for sealant joints. Being close to the B9087, Haroldswick is straightforward for us to reach. We also cover Baltasound (3 miles south-west), Clivocast (8 miles south), Cullivoe (9 miles south-west), Houbie (14 miles south) and Camb (15 miles south-west) for sealant joints. Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.
Near you in Haroldswick
Nearby you’ll also find Unst Heritage Centre (0.6 miles south-west). For a walk, there’s Little Heog and Loomer Shun.
What we’re called out for in Haroldswick
No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, which is why regular inspection pays.
Site and facilities staff are often the first to spot these:
- External beads that have gone brittle and cracked
- Greasy, split joints in a kitchen or tea point
- Window and door perimeter joints that have cracked open
- Wall and floor joints that have lost their seal
A lasting commercial joint around Haroldswick begins with the old bead fully out and the faces clean and dry.
Comparing quotes
- Will failed sealant be removed rather than covered?
- How joint depth will be controlled
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?
What happens if it’s left?
A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation. Around smaller places like Haroldswick, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Why us?
- Failed material removed, not covered up
- Constructionline member
- Colours chosen to suit frames, cladding or finishes where possible
- Public liability insurance in place
Commercial clients in Haroldswick
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Questions we’re asked in Haroldswick
Do you work on the island where Haroldswick is?
Yes. Islands are part of our area, Haroldswick included. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.
Can you match sealant colours for premises in Haroldswick?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Is the old sealant taken out first?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What site paperwork can you provide?
The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
