Facade sealing for Walkerburn sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Your questions answered

Can you work to our programme on a site in or near Walkerburn?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Which documents can you supply for work in Walkerburn?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

What do you charge?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email drawings and photos.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will tell you which.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

About our facade sealing in Walkerburn

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. The enquiries we see most involve patch repairs that keep failing and weathered joints at frame-to-structure perimeters, across coping and flashing joints, shopfront frames and window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Walkerburn it comes down to the same thing: the right product in a properly prepared joint.

External sealing around Walkerburn depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Surface by surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Where we can, we combine work around Walkerburn with other jobs nearby. Let us know if your dates have any give.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Make sure the joints can be reached
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

Advice

Sites and facades in and around Walkerburn

Building work in Walkerburn 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. A 2-mile radius around Walkerburn takes in a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Hotels like Tweed Valley Hotel, less than half a mile north-east of Walkerburn, rarely close for long, so refurbishment mastic is phased floor by floor. Historic houses such as Peel House, 4.6 miles to the east of Walkerburn, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Walkerburn is about 8 miles west of Galashiels, in the Scottish Borders. We cover commercial sites throughout Walkerburn. Our the Scottish Borders coverage takes in 91 places. For work in that direction, see our Edinburgh page, about 23 miles away.

When something else is needed

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

  • Joints whose design needs changing by the specifier
  • Damp caused by condensation inside the building
  • Arranging specialist high-level access, which is planned with the client

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.

Joints and surfaces we work on

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

What happens if it’s left?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. For buildings near Walkerburn, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Quoting for work in Walkerburn

  • The product specified

  • What the building is and how it’s used
