When to call us in Scottish Borders
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
It’s worth sending us details if you spot any of the following:
- Brittle perimeter mastic across a building
- A mix of products and colours from past repairs
- Draught complaints from residents or tenants
- Mastic failing across several blocks on an estate
For owners and agents with buildings in or around Scottish Borders, block-wide mastic programmes deal with frames and external joints of the same age together.
Questions to ask before you book
- How they handle RAMS and site documents
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
Mastic sealing in Scottish Borders, done properly
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. 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. We work on communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are mastic failing across several blocks on an estate and leaks at window and door perimeters. Looking for mastic applicators who cover Scottish Borders? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
In smaller Scottish places like Scottish Borders, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Questions about Scottish Borders
Can you quote for mastic across several buildings in and around Scottish Borders?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Is Scottish Borders too small for you to travel to?
Not at all. Scottish Borders is within our area. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Scottish Borders is on Scotland’s drier eastern side. Cold mornings still limit when outside mastic can go on. Programmes allow for that
Churches, halls and community buildings such as Tweedsmuir Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Quoting for work in Scottish Borders
The price varies from site to site. It mainly depends on:
- The size and state of each joint
- Access and working height
- Whether the work must be split into stages
- How much existing material needs removing
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Drawings or a marked-up plan, if available
- The postcode of the building
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or use the quote form.
When it isn’t the sealant
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:
- Water coming in from the roof or rainwater goods
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Asbestos-containing sealant, which we don’t remove
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Where we work in Scottish Borders
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Track which buildings were done and when
- Protect low-level joints in entrances
- Plan resealing building by building rather than complaint by complaint
- Check the asbestos register before any old mastic is disturbed
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs near Scottish Borders are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
