Facade sealing for businesses in Dunning

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

How we handle facade sealing in Dunning

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around. If you are dealing with air leaks through failed facade joints and failed sealant on precast panel joints, we can help. One point of contact handles commercial sealant work in Dunning from the first photos to the final walk-round, whether it’s one building or several.

Construction around smaller Scottish places like Dunning is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Where we can, we combine work around Dunning with other jobs nearby. Tell us how flexible your dates are.

  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

  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000

Advice

Common questions from Dunning clients

Is a smaller place like Dunning outside your area?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on a hospital site such as St Margaret's Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

How do I request a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

What do you charge?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or send details through our quote form with a description of the work.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Which sealant do you use on facades?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Dunning, a repair visit takes planning, so it’s better to act early.

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Building owners, agents and FMs in Dunning

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Dunning can form part of a wider programme across Perth and Kinross.

Building owners and managing agents use us 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.

Different surfaces, different methods

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

When it isn’t the sealant

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

  • Replacing glass or failed glazing units
  • Joints too narrow for the movement they take, which need redesign
  • Damp caused by condensation inside the building

Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.

Where we work in Dunning

When to call us in Dunning

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

It’s worth sending us details if you spot any of the following:

  • Cold air coming in at window perimeters
  • Discoloured or dirty facade joints
  • Perimeter joints where frames meet the structure
  • Perimeter sealant that has split or peeled away

On any site in or around Dunning, the mastic follows the specification and the programme.
