Surface by surface

Bathrooms, en suites and washrooms

On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent, plot by plot or floor by floor.

Snagging before handover

The last pass before handover is where mastic snags are cleared. Snags are cleared room by room, cutting out damaged joints and resealing them properly.

About our construction mastic in Balgay

External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can typically carry on while the outside waits. If you have different trades sealing to different standards and missed perimeter joints on a new elevation, we can put it right, whatever the surface. Whoever orders the work in Balgay, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

City-centre sites in Scotland typically mean booked deliveries, tight storage and shared access. We work to the programme and the site rules, with CSCS-carded applicators.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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

Your questions answered

Is hospital work, at somewhere like Royal Victoria Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can work at a site such as University of Dundee fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How do you work with the site programme?

Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and adjusted as things change.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Are you CHAS accredited?

We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Public liability insurance is in place.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

Building and refurbishing in Balgay

With the shore within about 1 mile, Balgay counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The area within 2 miles of Balgay holds a good number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

For a contractor working at a hospital such as Royal Victoria Hospital (under half a mile south-east of Balgay), perimeter and facade sealing is planned around patients and deliveries. When a college such as Dundee and Angus College - Kingsway Campus, 2 miles to the north-east of Balgay, builds or refurbishes, the mastic package normally has to fit around students and staff. For contractors on a campus like University of Dundee (1.5 miles east of Balgay), facade and perimeter sealing has to fit around students and term dates.

Balgay is about 2 miles west of Dundee, in Dundee. Across the DD2 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 28 places across Dundee fall within our area, including Balgay.

Work on mastic packages is covered throughout DD2 and DD3, whatever the building. Among the streets we cover are Gala Avenue, Glamis Road and Elliot Road, and sites on any of them can send details for a fixed quote.

Why deal with it now?

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. If the frame is life-expired, we will tell you. Scottish city buildings take plenty of rain, so a split or hardened joint lets water into the wall. Resealing promptly protects the stone and the interior.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Commercial clients in Balgay

On site: what to expect

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 before we move to the next. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we’ll work to them.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

What we can’t put right

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Damage to finishes by other trades after we’ve sealed
  • Frame gaps too wide for sealant, which the installer needs to correct
  • Joint design decisions that belong to the architect or engineer

If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Surfaces we seal

  • Window and door perimeters
  • Sanitary and kitchen joints
  • Cladding and panel joints
  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Brick and block movement joints
