Questions we’re asked in Possilpark

Can you work at a site such as Cowlairs Industrial Estate, by Possilpark?

Yes, sites like Cowlairs Industrial Estate are within our area, along with the rest of Possilpark. Photos and a short description are enough for a first look.

Would you work within a site like Stobhill Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you seal facades in winter?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

How we handle facade sealing in Possilpark

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on shopfront frames, cladding panel joints and perimeter joints where frames meet the structure, and what we are called in for most is gaps between rainscreen or cladding panels and perimeter sealant that has split or peeled away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Possilpark, preparation and product choice get the time they need.

Where new frames meet sandstone or granite in a Scottish city, the sealant has to suit the stone: the right primer, a neutral-cure sealant and a colour that blends. That holds on a tenement as much as on a city-centre office.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Possilpark can sit alongside others in a wider programme across Glasgow.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Specialist high-level access methods
  • Movement beyond what any sealant can handle
  • Damp caused by condensation inside the building

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

  • Shopfront frames
  • Cladding panel joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints

Why it’s worth doing now in Possilpark

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, so the real damage is often some distance away. In a tenement or shared city building, water from a failed joint can reach other owners’ property, which makes early repair simpler for everyone. Acting early avoids disputes and bigger repairs.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why clients in Possilpark choose us

  • Public liability insurance in place
  • Colour agreed before work starts
  • A fixed quote before work starts
  • Over 20 years of commercial sealing

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Facades, frames and programmes in Possilpark

The west of Scotland, where Possilpark is, gets more rain than the east. We keep internal mastic in hand so wet days aren’t lost. Projects in Possilpark follow Scotland’s building regulations, with the local authority acting as verifier. We seal to the specification that sits behind the warrant.

For contractors refurbishing units at places like Cowlairs Industrial Estate, which lies east of Possilpark, the mastic covers cladding panels, roller-door and window perimeters. University estates such as Glasgow Caledonian University (1.3 miles south of Possilpark) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For contractors at a college like Glasgow Kelvin College - Springburn Campus, which lies east of Possilpark, perimeters and internal sealant are timed for the holidays.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. 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 usually involves inductions and permits. Tell us the rules and we will work to them.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Let us know about inductions and permits
