Facade sealing in Boleside, done properly

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Most enquiries involve patch repairs that keep failing and damp patches beside frames after rain, on cladding panel joints, coping and flashing joints and stone and brick facade joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Boleside, that means joint design, primers and backing rod as standard.

In smaller places such as Boleside, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What we can’t put right

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

  • Joints whose design needs changing by the specifier
  • Cracked or spalling substrates that need repair before sealing
  • Water getting in through cracked render or porous masonry

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Surfaces we seal

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

Why act early in Boleside

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Boleside before they leak.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Your questions answered

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

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

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

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

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.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

How a job runs

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Travel to smaller Scottish places like Boleside is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in

Cost factors for facade joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How accessible the joints are
  • Joint width, depth and condition
  • The site’s rules and procedures
  • Whether old sealant has to be cut out first

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • Clear photographs of the problem areas

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email a schedule or drawings.

When to bring in a specialist

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. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Facade sealing in Boleside: the local picture

Building work in Boleside comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. The mastic follows the specification that goes with the warrant. Boleside is in the east of Scotland, which is drier than the west. Winter mornings can still bring frost and condensation on steel and glass. We agree external dates with the site team and keep internal work ready.

When a college such as Borders College - Galashiels Campus, 1.2 miles to the north-east of Boleside, builds or refurbishes, the mastic package typically has to fit around students and staff. When units on a site such as Netherdale Industrial Estate, 1.3 miles north-east of Boleside, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Boleside is about 2 miles south of Galashiels, in the Scottish Borders. We cover commercial sites throughout Boleside. Across the Scottish Borders, 91 places are covered, including Boleside. Our Edinburgh page has more on work in that area.

Do you need facade sealing in Boleside?

Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

Things that typically lead to an enquiry:

  • Perimeter sealant that has split or peeled away
  • Cladding panel joints that have opened up
  • New sealant peeling off old mastic
  • Hard, chalky sealant that no longer flexes

Work at a hotel such as Kingsknowes Hotel (to the north-east of Boleside) tends to be programmed around bookings, mastic included.

What your quote should include

  • Will RAMS and insurance details be available?
  • Will failed sealant be removed rather than covered?
  • What the guarantee covers, and for how long
  • Can the work be phased to keep areas open?
