When to bring in a specialist
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Why act early in St Boswells
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. Renewing every failing joint on one visit is the sensible approach for a place like St Boswells. Photos of each area help us quote the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Why appoint us
- Sealing commercial buildings since 2005
- Colours confirmed for the specified product
- Work carried out by CSCS-carded applicators
- Products installed to the manufacturer’s instructions
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Keep product details for future maintenance
- Check frame gaps are within the sealant’s range before sealing
- Don’t force external sealing on a damp or frosty day
- Ask for joint and product checks before the package is urgent
Expect some settlement in the first months. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That normally means redoing finishes in a completed area. Checking perimeters before internal finishes go on avoids it.
Questions about St Boswells
Can you work at a site such as Tweed Horizons Business Centre, by St Boswells?
Yes. Our area takes in St Boswells and its surroundings, with estates and business parks such as Tweed Horizons Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
Is hospital work, at somewhere like Dingleton Hospital, something you do?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What does a mastic package normally include?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens in one fixed quote.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
