Mastic sealing for Sound sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Log resealing dates block by block
- Share your contractor requirements early
- Ask residents or tenants to report leaks and draughts early
- Avoid piecemeal callouts where you can
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Mastic sealing in Sound
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Most enquiries involve open joints in brickwork or panels and draught complaints from residents or tenants, across shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sound, preparation and product choice get the time they need.
Around smaller places such as Sound, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic usually fails first.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Advice
Surface by surface
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Why it’s worth doing now in Sound
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Sound, a repair visit takes planning, so it’s better to act early.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Failed window or door frames, which need a window contractor
- Materials that need asbestos testing before work
- Masonry that has broken away beside the joint
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Questions we’re asked in Sound
Do you work on the island where Sound is?
Yes. Every Scottish council area is within our area, and that includes island locations such as Sound. We group island work where we can and plan around the crossings.
Does the sea air around Sound change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Looking after buildings in and around Sound
Sound lies within about 1 mile of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Sound is on Scotland’s drier eastern side. Frost and condensation on winter mornings can still delay outside mastic. Block programmes are built with that in mind
Schools and community buildings such as Anderson High School need frame and external mastic kept sound like any building. Property owners at sites such as North Ness Business Park (1.4 miles north-east of Sound) can have mastic renewed between lettings.
Sound is about 1 mile south-west of Lerwick, in the Shetland Islands. We cover commercial sites throughout Sound, whether it’s a single job or part of a planned programme. 63 places across the Shetland Islands fall within our area, Sound among them.
We cover the ZE1 postcode districts. For a building on Quoys Road, South Road and Oversund Road or nearby, send details and we’ll quote for mastic joints. Sites close to Sound are covered too, including Lerwick (1 mile north-east), Gulberwick (2 miles south-west), Gremista (2 miles north), Grindiscol (2 miles east) and Heogan (2 miles north-east). Among the larger centres in the Shetland Islands is Sound, and we take on mastic joints for its commercial and public buildings. Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you call 01277 525 020 or send photos by email.

Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
