Facade sealing for Blackhall sites

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

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Give us the access times and building rules for your premises in Blackhall, and we’ll plan the work to suit, phased where areas need to stay in use.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we’ll be in

How we handle facade sealing in Blackhall

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. We work on shopfront frames, perimeter joints where frames meet the structure and cladding panel joints, and the failures we are asked to look at most are hard, chalky sealant that no longer flexes and gaps between rainscreen or cladding panels. Whoever orders the work in Blackhall, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Sandstone and, in Aberdeen, granite buildings need care when new windows or panels are sealed against them: neutral-cure products that won’t mark the masonry, primed where the maker says, in a colour that sits with it.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Why act early in Blackhall

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. In Blackhall, as across Scotland, rain finds any gap, so a split or hardened joint lets water into the wall. Resealing promptly protects the stone and the interior.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

When to call us in Blackhall

When the sealant tears down its centre, it has typically been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

These are often picked up first by site or facilities staff:

  • Leaks at window and door perimeters
  • Old perimeter mastic that has dried out
  • Perimeter sealant that has split or peeled away
  • Draughts around frames and panels

When a college such as Edinburgh College - Granton Campus, 1.3 miles to the north of Blackhall, builds or refurbishes, the mastic package usually has to fit around students and staff.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply
  • What the guarantee covers, and for how long

Questions about Blackhall

Does a coastal location like Blackhall affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Can work at a site such as University of Edinburgh - Lauriston Campus fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you replace failed glazing units?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Installing or repairing glazing systems
  • Specialist high-level access methods
  • Damaged frames that need replacing

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.

Where we work in Blackhall

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

Keeping the joints sound

For the best life from the joints:

  • Ask about asbestos in pre-2000 mastic
  • Inspect facade joints on a regular cycle
  • Avoid harsh cleaners on facade sealant
  • Plan facade sealing alongside redecoration

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Quoting for work in Blackhall

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • How much there is to seal
  • Whether old sealant has to be cut out first

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • The site address and postcode
  • Any specification or named product
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or use the quote form if you’d rather talk the job through.

Facades, frames and programmes in Blackhall

Blackhall lies within about 2 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Building work in Blackhall comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. The mastic package follows the approved specification.

New units and refits on sites such as Craigleith Retail Park (less than half a mile east of Blackhall) need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Western General Hospital (Edinburgh), which lies east of Blackhall, perimeter and facade sealing is planned around patients and deliveries.
