Construction mastic in Selkirk
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. We work on brick and block movement joints, internal decorators’ caulk and cladding and panel joints, and what we are called in for most is perimeter gaps outside the sealant’s range and sealant knocked or painted over by other trades. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Selkirk, that means joint design, primers and backing rod as standard.
Construction around smaller Scottish places like Selkirk is often one-off schemes: a school, a health centre, a hotel extension or a few houses. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Why deal with it now?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Selkirk, a repair visit takes planning, so it’s better to act early.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Colour options checked against the specified product
- Joints cleaned back to sound surfaces
- Colours chosen to suit frames, cladding or finishes where possible
- Coloured sealants to suit the setting, where available
Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Selkirk are often grouped with others in the same area. Tell us how flexible your dates are.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- Explain the parking and delivery arrangements

Advice
Common problems we fix in Selkirk
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Clients typically get in touch after noticing one or more of the following:
- External joints sealed in damp or cold conditions that are now failing
- A long mastic snag list close to completion
- Internal caulk splitting as the building dries out
- Sealant knocked or painted over by other trades
Older buildings in the area around Selkirk, such as Bowhill House, 2.9 miles to the west of Selkirk, need care when sealed: the product has to suit soft or historic materials.
Questions to ask before you book
- Their approach to joint depth and backing
- How long is the guarantee, and what does it include?
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Glazing units that are cracked or misted
- Oversized gaps that need packing or adjustment by others
- Damage to finishes by other trades after we have sealed
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

What affects the price in Selkirk
There’s no standard rate for sealant work, because every site is different. What we take into account:
- How much existing material needs removing
- Quantities, in metres or numbers
- How accessible the joints are
- Distance, for remote addresses
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Asbestos survey details if the building is older
- Access details, including height
- The type of building and who uses it
- The product your specification calls for

Common questions from Selkirk clients
Do you take on work at healthcare sites like Borders General Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is Selkirk off your patch?
Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you guarantee new-build sealant work?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
How do you work with the site programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
How do you choose the sealant?
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.
Do you seal on top of existing sealant?
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 accreditations do you hold?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.

When to bring in a specialist
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
