Questions about Brae
Is Brae inside the area you cover, given it’s on an island?
Yes. Every Scottish council area is within our area, and that includes island locations such as Brae. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Will you price a mastic programme across our Brae portfolio?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Mastic sealing for commercial buildings in Brae
Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you are dealing with movement joints with sealant missing and water getting in round frames after rain, we can help, whatever the surface. For commercial sealant work in Brae, you deal with one contact from quote to sign-off, whether it’s one building or several.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Brae is planned with the forecast. Programmes allow for the weather.
Work we carry out in the Shetland Islands comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email us and we will come back to it.

Blocks and managed buildings in Brae
Brae 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, so it’s worth inspecting those sides more often. The east of Scotland, where Brae is, gets less rain than the west. Cold mornings still limit when outside mastic can go on. We plan block programmes with some give for it
For owners and agents with buildings in or around Brae, block-wide mastic programmes deal with frames and external joints of the same age together. Wherever your building is in or near Brae, we look at the whole elevation before quoting, so you know what needs doing now.

What the job involves on each surface
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Brae. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Log resealing dates block by block
- List the paperwork your organisation requires when you send details
- Avoid piecemeal callouts where you can
- Have the asbestos survey to hand for older buildings
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Cost factors for mastic joints
We price every job individually. The main factors are:
- Which sealant the job calls for
- How accessible the joints are
- Working within restricted access windows
- Quantities, in metres or numbers
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- The type of building and who uses it
- Your programme or deadline
- Where the site is, with the postcode
- Clear photos of the problem areas
To get a fixed quote, call the office on 01277 525 020 or email drawings and photos. Our quote form is another easy route.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
