Common problems we fix in Silverknowes

Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.

Any of the following is a good reason to get the joints checked over:

  • Leaks that seem to come through a sealant line
  • Weathered facade sealant that no longer flexes
  • Sanitary sealant that has gone black and patchy
  • Expansion joints with the sealant torn out

In hotels such as Leonardo Hotel Edinburgh Murrayfield, 1 mile to the south of Silverknowes, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • What the guarantee covers, and for how long
  • What level of public liability insurance do they hold?
  • Who will actually carry out the work

Questions to ask before you appoint anyone

How we handle commercial sealant contractors in Silverknowes

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. If you are dealing with weathered facade sealant that no longer flexes and frame mastic that has hardened and come away from the wall, we can help, on window and door perimeters, movement joints in walls and floors and floor and threshold joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Silverknowes is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A lot of what we do in Silverknowes is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

City-centre premises in Scotland often come with tight access, shared closes and loading restrictions. Tell us when the building is open and how we get in, and the plan will follow, phased so offices and shops keep trading.

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.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Keep washroom and kitchen extraction working
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Look at the sealant around anything that has been moved or replaced

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks. If anything looks wrong, ring 01277 525 020 or email a schedule or drawings with a photo.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Cracking that needs a structural engineer to look at it
  • Suspect materials that need testing and specialist removal
  • Misted, cracked or failed glazing units (a glazier’s job)

If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Window and door perimeters
  • Washrooms and tea points
  • Movement joints in walls and floors
  • External facade joints
  • Kitchen worktops and splashbacks
  • Floor and threshold joints

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Common questions from Silverknowes clients

Is Drylaw Shopping Centre, near Silverknowes, within your area?

Yes. Estates, retail parks and business parks around Silverknowes, Drylaw Shopping Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Will our hotel in Silverknowes need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

How is commercial sealant work priced?

Start with whatever information is to hand. Questions or a site visit follow where needed, then a fixed quote.

Is Silverknowes in your area?

Yes. We cover Silverknowes, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or send photos by email.

Is the old sealant taken out first?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How a job runs

Where the site stays busy, 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 we move to the next. Work on a big city site in Scotland normally involves inductions and permits. Tell us the rules and we’ll work to them.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Point out parking and an unloading spot
  • Let building users know which areas are affected
  • Point out any areas we must not close

Request a quote

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or email the details over.

Shops, offices and hotels in and around Silverknowes

With the shore within about 1 mile, Silverknowes counts as a coastal location. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. A matched colour is only half the brief on an exposed frontage. The east of Scotland, where Silverknowes is, gets less rain than the west. Cold snaps still affect when external joints can be sealed. We plan external frontages and frames around that

Shops and cafés around stations like South Gyle station (2.5 miles south-west of Silverknowes) trade from early, so work is timed around them. If you have premises on more than one site, say at Drylaw Shopping Centre and West Shore Road Trading Estate, one contractor and one quote can cover both.

Silverknowes is about 3 miles north-west of Edinburgh, in Edinburgh. Any commercial site in Silverknowes is covered, whether it’s a single job or part of a planned programme. We work across 174 places in Edinburgh, from busy centres to rural villages.

We also cover Davidson's Mains (1 mile south-west), Muirhouse (1 mile east), Craigcrook (1 mile south), Drylaw (1 mile south-east) and West Pilton (1 mile east). Further afield, our area takes in Edinburgh (3 miles south-east), Leith (4 miles east), Bonnington (4 miles east), Greenside (3 miles east), Broughton (3 miles east) and Bellevue (3 miles east).
