When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
What we seal
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
- Communal entrances and stairwells

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Ashiestiel can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Blocks and managed buildings in Ashiestiel
Being in the east of Scotland, Ashiestiel gets less rain than the west coast. Frost and condensation on winter mornings can still delay outside mastic. Programmes allow for that
For agents with blocks near Galashiels station, 4 miles to the east of Ashiestiel, a block-wide mastic programme deals with frames, balconies and entrances in one go. With historic buildings such as Peel House, 0.3 miles to the south-east of Ashiestiel, in the wider area, owners of older properties around Ashiestiel should expect mastic to need a product that suits old masonry. Student blocks close to universities like Heriot-Watt University - Scottish Borders Campus (4.8 miles east of Ashiestiel) are easiest to work on between tenancies.
Ashiestiel is about 4 miles west of Galashiels, in the Scottish Borders. If you’re looking for mastic sealing in Ashiestiel, we can help, as we do across the Scottish Borders.

When to bring in a specialist
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.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Leave it or put it right?
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. For buildings near Ashiestiel, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Where we can, we combine work around Ashiestiel with other jobs nearby. Let us know if your dates have any give.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Flag any permit to work we’ll need
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work

Related advice
Your questions answered
Is a smaller place like Ashiestiel outside your area?
Not at all. Ashiestiel is within our area. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.
Can you quote for a block close to Galashiels station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long does a typical visit take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Do you check for asbestos in old sealant?
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.
