Mastic sealing near Finnieston

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Do you need mastic sealing in Finnieston?

Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.

It’s worth sending us details if you spot any of the following:

  • Damaged joints in communal entrances and corridors
  • Complaints coming in block by block
  • Leaks at window and door perimeters
  • Window mastic that has split and shrunk

Buildings close to stations like Exhibition Centre station, less than half a mile to the east of Finnieston, are often flats over shops, with frame mastic to keep sound.

Choosing a commercial sealant contractor

How we handle mastic sealing in Finnieston

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are worn sealant at communal door frames and the same joint failures repeated across a portfolio. One point of contact handles commercial sealant work in Finnieston from the first photos to the final walk-round, whether it’s one building or several.

In Scotland’s cities, housing associations look after blocks and estates of every age. Planned mastic programmes can renew frame and external joints block by block.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Pass on the site’s contractor rules when you get in touch.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Move anything stored against the joints
  • Flag any permit to work we’ll need
  • Send asbestos survey details if the building is pre-2000

What happens if it’s left?

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. In Finnieston, as across Scotland, rain finds any gap, and failed external joints let it into stone walls and around frames. Resealing promptly protects the stone and the interior.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Standard and matched colours in many product ranges
  • A Constructionline member, so easy to vet
  • Old sealant cut out, never sealed over
  • Colour agreed before work starts

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Looking after buildings in and around Finnieston

Finnieston is on Scotland’s wetter western side. The weather side of a block usually needs attention first. Outside mastic goes on in dry spells, with some flexibility in the programme. Finnieston has three care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.

Trustees of buildings like Sandyford Henderson Memorial Church can bring frame and external mastic into a planned maintenance list. Schools and community buildings such as Glasgow Gaelic School need frame and external mastic kept sound like any building.

What the job involves on each surface

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent and easier to manage.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for 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.

Questions we’re asked in Finnieston

How do tenement owners in Finnieston get shared-part mastic done?

Typically through the property factor, once the owners have agreed. We’re happy to deal with the factor directly.

Do you work for managing agents with blocks near Exhibition Centre station?

Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Will residents or tenants be disturbed?

We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

How long will the new sealant 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.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure.
