Mastic sealing in Glasgow

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

Looking after the joints

For the best life from the joints:

  • Start inspections with the most exposed faces
  • Ask residents or tenants to report leaks and draughts early
  • Share the asbestos register when you send details
  • Check sealant joints during planned building inspections

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

Mastic sealing for commercial buildings in Glasgow

Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you are dealing with damaged joints in communal entrances and corridors and no planned programme for sealant, we can help. For commercial sealant work in Glasgow, you deal with one contact from quote to sign-off, whether it’s one building or several.

Scotland’s city blocks are largely sandstone or, in Aberdeen, granite, and replacement windows set into those walls need a perimeter sealant that won’t mark the stone.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Why it’s worth doing now in Glasgow

Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Getting access arranged for a building in Glasgow takes time, so it makes sense to renew every failing joint while it’s in place.

Pricing mastic joints depends on how many there are, their condition and the access. Call for a quote.

Why clients in Glasgow choose us

  • Standard and matched colours in many product ranges

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Looking after buildings in and around Glasgow

Glasgow is in the west of Scotland, the wetter side of the country. The most exposed elevations need checking most often. We plan block programmes with the forecast in mind. There are four care or nursing homes within about 2 miles of Glasgow. Owners of care premises can bring window and door mastic into a phased programme planned around the home.

If you look after a block within reach of Anderston station (under half a mile north-east of Glasgow), frame and balcony mastic can be renewed on one programme. Schools and community buildings such as Our Lady and St Margaret's Primary School need frame and external mastic kept sound like any building. Property owners at sites such as Kingston Bridge Trading Estate (to the south-west of Glasgow) can have mastic renewed between lettings.

Glasgow is in Scotland. Glasgow sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 171 places in Glasgow, large and small.

Business premises anywhere in G33, G32, G53 and G46 are within our area for mastic joints. Streets here include Plantation Square, Minerva Square and George Square, and sites on any of them can send details for a fixed quote. With the A8 and A74 nearby, Glasgow is straightforward for us to reach. Sites close to Glasgow are covered too, including Plantation (1 mile west), Tradeston (1 mile east), Kinning Park (1 mile south-west), Sandyford (1 mile north) and Blythswood Hill (1 mile north-east). Further afield, our area takes in Yoker (5 miles north-west), Hillpark (3 miles south), Temple (3 miles north-west), Muirend (3 miles south), Newlands (3 miles south) and Anniesland (3 miles north-west).

Surface by surface

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We will confirm the colours available for the specified product.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Questions we are asked in Glasgow

Who arranges mastic work on a tenement in Glasgow?

Typically through the property factor, once the owners have agreed. We can quote to the factor or to the owners, for a single close or a whole block.

We manage a building near Anderston station. Can you help?

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

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.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

Can you reseal a whole block or estate?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we will work to them.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Share your working hours and any access restrictions

Quotes

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

What affects the price in Glasgow

The price varies from site to site. It mainly depends on:

  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • Working within restricted access windows

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email a schedule or drawings.
