Facade sealing in Clockmill

About our facade sealing in Clockmill

Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Most enquiries involve gaps between rainscreen or cladding panels and weathered joints at frame-to-structure perimeters, across perimeter joints where frames meet the structure, cladding panel joints and stone and brick facade joints. Facilities teams, main contractors and managing agents in Clockmill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction around smaller Scottish places like Clockmill 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.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Diagnose, treat, 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 handed back before we move to the next. Jobs near Clockmill are often grouped with others in the same area. Tell us how flexible your dates are.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use

Advice

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Arranging specialist high-level access, which is planned with the client

If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Clear debris that holds water against joints
  • Record the product and colour used on each elevation
  • Avoid harsh cleaners on facade sealant
  • Add perimeter sealant to planned maintenance checks

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Why deal with it now?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Clockmill, a repair visit takes planning, so it’s better to act early.

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Is Duns Industrial Estate, near Clockmill, within your area?

Do you take on work at healthcare sites like Knoll Community 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.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

How long do sealant joints last?

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

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Do you run new sealant over the existing bead?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
