Mastic sealing for Stobswell sites

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

After the work

To get the most from the new sealant:

  • Look at the sunniest and most exposed elevations first
  • Reduce knocks to communal area joints
  • Make it easy for occupiers to report draughts
  • Mention RAMS, insurance or CSCS requirements up front

Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.

One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Mastic sealing for commercial buildings in Stobswell

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on window and door perimeters on blocks, balcony and threshold joints and external wall and movement joints, and what we are called in for most is no planned programme for sealant and the same joint failures repeated across a portfolio. A specialist sealant contractor works differently from a general builder: on jobs in Stobswell, preparation and product choice get the time they need.

Many of Scotland’s city tenements are looked after by property factors. Shared-part mastic work is normally agreed by the owners, often through the factor, and can cover a whole close or block.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Building owners, agents and FMs in Stobswell

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

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Work on a big city site in Scotland normally involves inductions and permits. Tell us the rules and we will work to them.

  1. First we look at the mastic on each building and note what needs replacing.
  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. Each building is checked on completion and the work carries our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Agree which areas must stay open
  • Move anything stored against the joints

Should maintenance staff do it?

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

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What the job involves on each surface

External movement joints

External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.

When to call us in Stobswell

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.

Most enquiries start with something like this:

  • Repeated reactive repairs to the same buildings
  • Movement joints with sealant missing
  • Damp patches beside frames
  • Worn sealant at communal door frames

Landlords with units on estates such as Gallagher Retail Park, under half a mile to the south of Stobswell, can bring frame, door and external mastic across several units into one programme.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • Their approach to joint depth and backing
  • Proof of insurance

Choosing a commercial sealant contractor

Block-wide mastic in Stobswell

Stobswell sits close to the coast, within about 1 mile. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. Stobswell is on Scotland’s drier eastern side. Cold mornings still limit when outside mastic can go on. Programmes allow for that

Trustees of buildings like St Patrick's R.C. Church can bring frame and external mastic into a planned maintenance list. If you look after a block within reach of Dundee station, which lies south of Stobswell, frame and balcony mastic can be renewed on one programme.

Stobswell is about 1 mile east of Dundee, in Dundee. Across the DD3 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 28 places in Dundee, from busy centres to rural villages.
