Facade sealing in Darnick
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. We work on window and door perimeters, coping and flashing joints and cladding panel joints, and what we are called in for most is leaks at window and door perimeters and perimeter sealant that has split or peeled away. Looking for mastic applicators who cover Darnick? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
External sealing around Darnick depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Contractors’ notes for Darnick
Darnick has a number of hotels close by, all within 2 miles. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Darnick is in the east of Scotland, which is drier than the west. Cold, damp starts still stop external sealing on some days. External dates keep a little give.
Work at a hotel such as Waverley Castle Hotel (to the north of Darnick) tends to be programmed around bookings, mastic included. For contractors at a college like Borders College - Galashiels Campus, which lies west of Darnick, perimeters and internal sealant are timed for the holidays. When units on a site such as Tweedbank Industrial Estate (to the west of Darnick) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs near Darnick are often grouped with others in the same area. Let us know if your dates have any give.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits

Common questions from Darnick clients
Is Tweedbank Industrial Estate, near Darnick, within your area?
Yes. Our area takes in Darnick and its surroundings, with estates and business parks such as Tweedbank Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is hospital work, at somewhere like Borders General Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Will rain stop the work?
Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things throughout the job.
Do you run new sealant over the existing bead?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
What happens if it’s left?
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. For buildings near Darnick, dealing with all the failing joints at once saves return trips. Send photos and we will quote for everything together.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief window cleaners about newly sealed joints
- Check that rainwater leaves the facade the way it was designed to
- Check the asbestos register before old mastic is disturbed
- Plan facade sealing alongside redecoration
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal across the elevation.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Darnick can sit alongside others in a wider programme.
