Facade sealing for North Tolsta sites

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

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Arranging specialist high-level access, which is planned with the client
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Surfaces we seal

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

Coping and flashing joints are included where sealant is the specified fix. If you’re dealing with unsightly perimeter sealant on a visible elevation and perimeter sealant that has split or peeled away, we can put it right, on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in North Tolsta is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Quoting for work in North Tolsta

The price varies from site to site. Expect it to depend on:

  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • Working within restricted access windows

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.

A facade joint near North Tolsta lasts when width, depth and backing are right, not just the finish. On any site in or around North Tolsta, the mastic follows the specification and the programme.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a building near North Tolsta, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed 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.

Getting the site ready

Should maintenance staff do it?

Certain joints really need a specialist: 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.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Ask about asbestos in pre-2000 mastic
  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year
  • Keep sills, gutters and drainage paths clear

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.

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

Questions we are asked in North Tolsta

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

Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is North Tolsta inside the area you cover, given it’s on an island?

Yes. Every Scottish council area is within our area, and that includes island locations such as North Tolsta. We group island work where we can and plan around the crossings.

Do you provide access for facade work?

We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
