Mastic sealing in Sandbank
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have a mix of products and colours from past repairs and damp patches beside frames, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sandbank, preparation and product choice get the time they need.
Around Sandbank, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Look at the sunniest and most exposed elevations first
- Protect low-level joints in entrances
- Group repairs into a planned programme
- Encourage occupiers to report problems at frames
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For work around Sandbank, 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.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Flag any permit to work we’ll need
- Point out parking and an unloading spot
- Move anything stored against the joints
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice
Different surfaces, different methods
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Common questions from Sandbank clients
We manage a building near Gourock station. Can you help?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Does the sea air around Sandbank change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

Why it’s worth doing now in Sandbank
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Around smaller places like Sandbank, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Commercial clients in Sandbank
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites around Sandbank. Several sites can go on one quote, which keeps the paperwork simple.
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Block-wide mastic in Sandbank
Sandbank 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. The west of Scotland, where Sandbank is, gets more rain than the east. Frame mastic on weather-facing sides tends to fail first. Outside mastic goes on in dry spells, with some flexibility in the programme.
Blocks of flats and mixed-use buildings often cluster around stations such as Gourock station, 4.9 miles east of Sandbank, and their window and balcony mastic tends to age at the same rate across a building. Schools and community buildings such as Dunoon Grammar School need frame and external mastic kept sound like any building. Trustees of buildings like Sandbank Parish Church can bring frame and external mastic into a planned maintenance list.
