Mastic sealing across Leith

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

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Leaks from above rather than through a joint
  • Frames that are rotten, warped or broken

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Surfaces we seal

  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • External wall and movement joints
  • Communal entrances and stairwells
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks

Mastic sealing in Leith, done properly

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. The enquiries we see most involve a mix of products and colours from past repairs and estate-wide sealant that is simply worn out, across window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Leith it comes down to the same thing: the right product in a properly prepared joint.

In Scotland’s cities, housing associations look after blocks and estates of every age. A planned programme deals with failed mastic across an estate, block by block.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

When to call us in Leith

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

Site and facilities staff are often the first to spot these:

  • Leaks at window and door perimeters
  • No planned programme for sealant
  • A mix of products and colours from past repairs
  • Movement joints with sealant missing

Owners of student blocks near University of Edinburgh - Holyrood Campus (2.1 miles south of Leith) can schedule frame and external mastic for the summer vacation.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Whether their applicators hold CSCS cards
  • What the guarantee covers, and for how long
  • Their public liability cover

Choosing a commercial sealant contractor

Mastic sealing around Leith: points for this area

Leith is within about 1 mile of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Five care or nursing homes sit less than 2 miles from Leith. Owners of care premises can bring window and door mastic into a phased programme planned around the home.

Site managers at schools like Leith School of Art can fit frame mastic into the summer works. If you’re responsible for a building such as St Ninians Church, frame and door mastic needs the same attention as any other property.

Leith is about 3 miles north-east of Edinburgh, in Edinburgh. Commercial clients in Leith can call on us for mastic joints, as part of our coverage of Edinburgh. Across Edinburgh, 174 places are covered, Leith among them.

Aftercare for building managers

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

  • Make it easy for occupiers to report draughts
  • Check sealant joints during planned building inspections
  • Protect low-level joints in entrances
  • Have the asbestos survey to hand for older buildings

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.

FAQs: Leith

Do you cover business parks and estates near Leith, such as Tower Street Industrial Estate?

Yes, sites like Tower Street Industrial Estate are within our area, along with the rest of Leith. Send details of the unit and the work through our quote form for a quick quote.

Will you work in a care home in Leith without moving residents out?

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.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Can you plan resealing across several buildings?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

What paperwork can you provide?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What about access for upper-floor joints?

Every block is different. We agree access with you at quote stage so there are no surprises.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. City jobs in Leith normally need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Getting the site ready
