About our mastic sealing in Boleside
Owners and agents typically inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. Site teams most often ask us about failed external movement joints and leaks at window and door perimeters, on communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks. Most enquiries from Boleside 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 Boleside, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

General trades versus a specialist
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
After the work
After handover, these steps help:
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
- Have the asbestos survey to hand for older buildings
- Group repairs into a planned programme
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Boleside, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Let us know about inductions and permits
- Warn occupants and staff about the work
- Arrange parking or a loading space

How the job changes by surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. We plan around the site hours and access windows you give us.
What we’re called out for in Boleside
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.
Site and facilities staff are often the first to spot these:
- The same joint failures repeated across a portfolio
- Repeated reactive repairs to the same buildings
- Open joints in brickwork or panels
- Old repairs sealed over failed mastic
Student accommodation around universities such as Heriot-Watt University - Scottish Borders Campus, 1.3 miles to the north-east of Boleside, is usually managed block by block, which suits a planned mastic programme.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
Planned mastic for Boleside portfolios
Being in the east of Scotland, Boleside gets less rain than the west coast. Frost and condensation on winter mornings can still delay outside mastic.
Property owners at sites such as Netherdale Industrial Estate, 1.3 miles to the north-east of Boleside, can have mastic renewed between lettings. With historic buildings such as Peel House (to the west of Boleside) in the wider area, owners of older properties around Boleside should expect mastic to need a product that suits old masonry.

Questions we’re asked in Boleside
We manage a building near Galashiels station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Is Boleside too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Do you check for asbestos in old sealant?
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.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
