Sealant applicators in Leith

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. Primer is used wherever the manufacturer calls for it on that surface. Most enquiries involve smeared sealant across finishes from a rushed job and hardened, chalky sealant on south-facing or exposed elevations, on washrooms and tea points, external facade joints and movement joints in walls and floors. One point of contact handles commercial sealant work in Leith from the first photos to the final walk-round, whether it’s one building or several.

Occupied buildings in Leith need the work phased: washrooms in turn, floors in sections and entrances kept open.

In Scotland’s cities, commercial premises are packed closely, from stone-fronted offices to shops on the ground floor of tenement blocks. Where a shop sits below tenement flats, work on the frontage or shared parts may involve the property factor.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Don’t let cleaning or traffic back on before the cure time is up
  • On pre-2000 buildings, share the asbestos information before work starts
  • Add sealant to the planned maintenance inspection list
  • Keep abrasive pads and scrapers off resealed joints

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.

Common questions from Leith clients

Does the sea air around Leith change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is Tower Street Industrial Estate, near Leith, within your area?

Yes. We cover Leith and the area around it, including industrial estates, business parks and retail parks such as Tower Street Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

How long before the joints can be used?

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

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you take on multi-site sealant work?

Yes. We regularly take on multi-site work and planned maintenance programmes, priced site by site or as one programme.

Which site documents can you send us?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Is the old sealant taken out first?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

Shops, offices and hotels in and around Leith

With the shore within about 1 mile, Leith counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Where a frontage needs a particular colour, the product still has to suit that exposure. At least three named trading, business or retail sites lie within about 3 miles of Leith. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.

For premises near Edinburgh Waverley station, 2.1 miles to the south of Leith, footfall is part of the plan: work is phased so shops and offices keep trading. Sites a few miles apart, such as Tower Street Industrial Estate and North Leith Sands Industrial Estate, can share one programme and one point of contact. In hotels such as Abbot's House Hotel, 0.5 miles south-east of Leith, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Leith is about 3 miles north-east of Edinburgh, in Edinburgh. Our applicators travel to Leith for work on sealant joints, handled exactly as we handle every other area. Our Edinburgh coverage takes in 174 places.

Business premises anywhere in EH6, EH5 and EH1 are within our area. Among the streets we cover are Fyfe Lane, Haig Lane and Mill Lane. We also cover Timber Bush (1 mile south), North Leith (1 mile south-west), Bonnington (1 mile south-west), Newhaven (1 mile west) and Victoria Park (1 mile west). Bigger towns within reach include Edinburgh (3 miles south-west), West End (3 miles south-west), West Coates (3 miles south-west), Sciennes (3 miles south), Merchiston (3 miles south-west) and Newington (3 miles south). Among the larger centres in Edinburgh is Leith, and we take on sealant joints for its commercial and public buildings.

Local landmarks in Leith

Around Leith, our work takes us to commercial buildings near Leith Academy, McDonald Road Library and Taylor Gardens and the streets around them. For rail, the closest station is Edinburgh Waverley station, roughly 2.1 miles south of the centre. A little further out are Ocean Terminal (less than half a mile west) and Edinburgh Castle (2.5 miles south-west). For a walk, there’s The New Leaf Co-op and Whinny Hill.

Surface by surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Cost factors for sealant joints

Before we quote, we look at:

  • Location, for remote and island sites
  • Working within restricted access windows
  • How accessible the joints are
  • Joint width, depth and condition

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it
  • Any specification or named product
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

What happens if it’s left?

Leaving a failed joint rarely saves money. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. In a tenement or shared city building, water from a failed joint can reach other owners’ property. Fixing it promptly keeps repairs small.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What you get with us

  • Old sealant cut out, never sealed over
  • One number for every site we cover
  • RAL and finish matching where the product range allows
  • Coloured sealants to suit the setting, where available

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For premises in Leith, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Preparing the site

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • Share your working hours and any access restrictions
