Questions about Newstead
Can you work on a hospital site such as Borders General Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Newstead too small for you to travel to?
Not at all. Newstead is within our area. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you work plot by plot or floor by floor?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team.
Do you take on mastic snagging only?
Yes. Share the list and photos, and a fixed quote follows.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
How we handle construction mastic in Newstead
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. The enquiries we see most involve old sealant on a refurbishment that needs stripping before new work and frame gaps too wide for sealant alone, across floor and skirting junctions, brick and block movement joints and internal decorators’ caulk. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Newstead, that means joint design, primers and backing rod as standard.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Newstead that means watching the forecast. We build some give into the plan and agree it with the site manager.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the job changes by surface
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly.
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker.
Sites and facades in and around Newstead
A 2-mile radius around Newstead takes in several hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Building work in Newstead comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. We seal to the specification that sits behind the warrant.
Hotels like Station Hotel, 0.9 miles west of Newstead, rarely close for long, so refurbishment mastic is phased floor by floor. Units on estates such as Tweed Horizons Business Centre, 2.1 miles south-east of Newstead, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Newstead is about 4 miles east of Galashiels, in the Scottish Borders. Across the TD6 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 91 places in the Scottish Borders. There’s a separate page for Edinburgh, about 31 miles away.
We take on mastic packages across the TD6 postcode area, for business premises of every kind. Buildings on Main Street, Claymires Lane and Back Road are within our area for mastic packages. Close to Newstead, our area also takes in Melrose (1 mile west), Gattonside (1 mile north-west), Newtown St Boswells (2 miles south-east), Darnick (2 miles west) and Bowden (2 miles south). A short drive away, we cover Galashiels (4 miles west), Hawick (13 miles south), Kelso (10 miles east), Selkirk (7 miles south-west), Jedburgh (10 miles south-east) and Wilton (13 miles south).
Landmarks near Newstead
The nearest railway station is Tweedbank station, roughly 2.5 miles west. A little further out are Commendators House Museum (0.9 miles west) and Castle Holydean (2.9 miles south-west). Not far away are Eildon Hill North and Bemersyde Moss.
Common problems we fix in Newstead
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Look out for the following:
- Perimeter gaps outside the sealant’s range
- Sealant knocked or painted over by other trades
- A mastic package split between trades with no clear owner
- Window and door perimeters that won’t pass inspection
For contractors on a campus like Heriot-Watt University - Scottish Borders Campus, 3.5 miles to the west of Newstead, facade and perimeter sealing has to fit around students and term dates.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Deciding which fire-stopping product a penetration needs
- Rework caused by others damaging completed areas
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
