About our mastic sealing in Sandness
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. Site teams most often ask us about movement joints with sealant missing and damaged joints in communal entrances and corridors, across communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms. Most enquiries from Sandness start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Sandness, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Honest limits
Honesty saves time and money. New sealant won’t cure:
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.

When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Planned mastic for Sandness portfolios
With the shore within about 1 mile, Sandness counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. Island jobs, Sandness among them, are planned around the ferry and the forecast. We group island buildings so each crossing covers as much as possible.
Around Sandness, a planned programme renews failed mastic across a building or estate in one go.
Sandness is in the Shetland Islands. Across the ZE2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 63 places in the Shetland Islands, large and small.
Work on mastic joints is covered throughout ZE2, for business premises of every kind. Sites close to Sandness are covered too, including Melby (1 mile north-west), Walls (6 miles south-east), Aith (10 miles east), Easter Skeld (11 miles south-east) and Brae (12 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

What affects the price in Sandness
Quotes vary with the job. Expect it to depend on:
- How much there is to seal
- How accessible the joints are
- Travel to remote or island sites
- Working within restricted access windows
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
What we need to price the job
However big the job, the same details help:
- Your programme or deadline
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- The site address and postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
When to call us in Sandness
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
It’s worth sending us details if you spot any of the following:
- Draughts at frames across a block
- No planned programme for sealant
- Old repairs sealed over failed mastic
- Damaged joints in communal entrances and corridors
Older community buildings, St Margaret's Kirk and Graveyard among them, often have frames of mixed ages whose mastic varies.
Before you book anyone
- What the guarantee covers, and for how long
- Their public liability cover
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
Aftercare for building managers
To get the most from the new sealant:
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Make mastic part of routine maintenance checks
- Prioritise elevations facing the weather
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
FAQs: Sandness
Will you travel to Sandness on the island?
Yes. Every Scottish council area is within our area, and that includes island locations such as Sandness. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Do you take on block-wide or estate-wide mastic work in Sandness?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
What paperwork can you provide?
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.
