What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Cracking that needs a structural engineer to look at it
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Water from a services leak rather than a joint
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
What Coulter’s businesses ask us to seal
Being in the east of Scotland, Coulter gets less rain than the west coast. Frost and condensation on winter mornings can still hold up external sealing. We plan external frontages and frames around that The 3 miles around Coulter take in two named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it.
In hotels such as Cornhill House Hotel, 1.1 miles north-west of Coulter, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. On estates like Lindsaylands Industrial Estate, 2.5 miles north of Coulter, the office and welfare end of each unit has its own sealant to maintain.
Coulter is about 15 miles south-east of Carluke, in South Lanarkshire. Anywhere in ML12, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Coulter is one of 134 places in South Lanarkshire on our list for sealant joints. There’s a separate page for Edinburgh, about 28 miles away.
If you need commercial sealant contractors in ML12, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside Coulter, we cover Symington (2 miles north-west), Biggar (3 miles north), Quothquan (4 miles north), Thankerton (4 miles north-west) and Wiston (4 miles west). Further afield, our area takes in Carluke (15 miles north-west), Lanark (11 miles north-west), Lesmahagow (14 miles west), Kirkmuirhill (15 miles west), Forth (14 miles north-west) and Douglas (12 miles west).

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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.
How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Tell us who will meet us and how to get in at your building near Coulter. That goes into the plan alongside the quote.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Share the asbestos register for older buildings

Advice
Common problems we fix in Coulter
When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
Any of the following is a good reason to get the joints checked over:
- Hardened, chalky sealant on south-facing or exposed elevations
- Leaks that seem to come through a sealant line
- Shrunken sealant along kitchen worktops and splashbacks
- Messy, uneven beads from earlier work that let the building down
Sites a few miles apart, such as Lindsaylands Industrial Estate and Biggar Business Park, can share one programme and one point of contact.
Questions to ask before you book
- Their pre-qualification and accreditations
- Is the sealant right for the movement and the substrate?
- Who will actually carry out the work
- Do they follow the manufacturer’s priming guidance?
Coulter: questions and answers
Is a smaller place like Coulter outside your area?
Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can the sealant on our Coulter premises match the finishes?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do you keep disruption to occupiers down?
It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing for as long as the cure needs.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Can you supply RAMS and insurance details?
The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.
What do you need from us to quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.
Keeping the joints sound
After handover, a little attention goes a long way:
- Respect the cure time before reopening an area
- Act on the first lifting edges rather than waiting
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep a record of which joints were resealed and when
New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint. Keeping signs or barriers up until then protects the finish.
Tenants and staff spot black or split sealant quickly, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.
