Facade sealing near Tweedbank

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.

Joints and surfaces we work on

  • Shopfront frames
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Cladding panel joints

Facade sealing in Tweedbank

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about old perimeter mastic that has dried out and gaps between rainscreen or cladding panels, across stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure. Looking for mastic applicators who cover Tweedbank? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

External sealing around Tweedbank depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Investigate damp beside windows promptly
  • Add perimeter sealant to planned maintenance checks
  • Check that rainwater leaves the facade the way it was designed to
  • Record the product and colour used on each elevation

Record the sealant type and date on the building file. Future work can then match the product and colour without guesswork.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Contractors’ notes for Tweedbank

There are a number of hotels within about 2 miles of Tweedbank. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Building work in Tweedbank comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification.

Recladding or extending a unit at a site like Tweedbank Industrial Estate, under half a mile east of Tweedbank, brings panel joints and frame perimeters into the programme. Work at a hotel such as Kingsknowes Hotel, 0.6 miles west of Tweedbank, tends to be programmed around bookings, mastic included.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Site staff or a sealant 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.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Questions we’re asked in Tweedbank

Can work at a site such as Heriot-Watt University - Scottish Borders Campus fit around teaching?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is hospital work, at somewhere like Borders General Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you look at water coming in around a frame?

Yes. Photos help, and you can speak to us on 01277 525 020 or email drawings and photos to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.

Can you work while the building is occupied?

Typically, yes. We phase the work so most of the building stays in use.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Should we check old sealant for asbestos?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions.

When to call us in Tweedbank

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.

Most enquiries start with something like this:

  • Damp patches beside frames after rain
  • Unsightly perimeter sealant on a visible elevation
  • Air leaks through failed facade joints
  • Perimeter sealant that has split or peeled away

Building work at universities like Heriot-Watt University - Scottish Borders Campus (0.8 miles north-west of Tweedbank) is often timed for the summer, mastic included.

Questions to ask before you book

  • Who will actually carry out the work
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance
  • How they handle RAMS and site documents

Our contractor checklist

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Tell us who will meet us and how to get in at your building near Tweedbank. That goes into the plan alongside the quote.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Send any specification or drawings in advance
  • Arrange parking or a loading space
  • Let us know about inductions and permits

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
