Facade sealing across Forth

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

Facade sealing for commercial buildings in Forth

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. If you have gaps between rainscreen or cladding panels and perimeter sealant that has split or peeled away, we can help, on window and door perimeters, shopfront frames and stone and brick facade joints alike. A single leaking joint is often how a building in Forth first comes to us: we look at the rest while we’re there and tell you what we find.

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

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common questions from Forth clients

Which documents can you supply for work in Forth?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

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

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Can staff carry on working while you are here?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you just add new sealant on top?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. That is what makes the new joint last.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Sites and facades in and around Forth

Building work in Forth 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. Being in the east of Scotland, Forth gets less rain than the west coast. Cold, damp starts still stop external sealing on some days. We programme around it with the site team.

A facade joint near Forth lasts when width, depth and backing are right, not just the finish.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Damaged frames that need replacing
  • Joints too narrow for the movement they take, which need redesign
  • Providing access systems for the work

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Joints and surfaces we work on

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

When to call us in Forth

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, and the joint opens with the first real movement.

Typical triggers for a call:

  • Weathered joints at frame-to-structure perimeters
  • Gaps between rainscreen or cladding panels
  • Hard, chalky sealant that no longer flexes
  • New sealant peeling off old mastic

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

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Access and working height
  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers
  • Which sealant the job calls for

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

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

  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • What the building is and how it’s used
  • Access details, including height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Maintenance after handover

A few simple habits keep the new joints working:

  • Combine resealing with other works that need access
  • Report water ingress at frames as soon as it shows
  • Inspect facade joints on a regular cycle
  • Never let anyone seal over old sealant

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.

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.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Travel to smaller Scottish places like Forth is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  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. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Move anything stored against the joints
  • Tell staff and tenants when we’ll be in
  • Have the specification and drawings to hand
