Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Plan resealing building by building rather than complaint by complaint
  • Prioritise elevations facing the weather
  • Protect low-level joints in entrances
  • Make mastic part of routine maintenance checks

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

Mastic sealing for commercial buildings in Dundee

Owners and agents typically inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you are dealing with no planned programme for sealant and damaged joints in communal entrances and corridors, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Dundee it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Tenements are a large part of the housing in Scotland’s cities, and shared repairs often go through a property factor. Mastic around windows and on shared parts can be renewed across a close or a whole block, with the owners agreeing the work.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. In a Scottish city, kerbside space and loading need planning, especially near the centre. Tenement closes, shared stairs and factor approvals may also be involved.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

What we need from you

  • Move anything stored against the joints
  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed

Advice

How the job changes by surface

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading so the work is phased.

External movement joints

The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Water coming in from the roof or rainwater goods
  • Leaks through the frame itself rather than the perimeter
  • Materials that need asbestos testing before work

If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Where we work in Dundee

  • External wall and movement joints
  • Communal kitchens and washrooms

Questions about Dundee

Can you work in a care home near Dundee with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Is Kingsway West Retail Park, near Dundee, within your area?

Yes. Estates, retail parks and business parks around Dundee, Kingsway West Retail Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Quoting for work in Dundee

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Removal of failed or old sealant
  • How accessible the joints are
  • Travel to remote or island sites
  • The size and state of each joint

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Mastic sealing in Dundee: the local picture

With the shore within about 2 miles, Dundee counts as a coastal location. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, and they deserve more regular inspection. The 2 miles around Dundee include 10 care or nursing homes. Care home owners need frame and external mastic kept sound without unsettling residents.

Historic properties like Camperdown House (2.5 miles west of Dundee) show the age of some local stock, where frame mastic must suit soft brick or stone. If your remit includes a building such as Scottish School of Contemporary Dance, frame and door mastic can be programmed for the holidays. Owners of student blocks near Abertay University (to the south of Dundee) can schedule frame and external mastic for the summer vacation.
